# Gradle start up script for POSIX generated by Gradle.
|
||||
#
|
||||
# Important for running:
|
||||
#
|
||||
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||
# noncompliant, but you have some other compliant shell such as ksh or
|
||||
# bash, then to run this script, type that shell name before the whole
|
||||
# command line, like:
|
||||
#
|
||||
# ksh Gradle
|
||||
#
|
||||
# Busybox and similar reduced shells will NOT work, because this script
|
||||
# requires all of these POSIX shell features:
|
||||
# * functions;
|
||||
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||
# * compound commands having a testable exit status, especially «case»;
|
||||
# * various built-in commands including «command», «set», and «ulimit».
|
||||
#
|
||||
# Important for patching:
|
||||
#
|
||||
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||
#
|
||||
# The "traditional" practice of packing multiple parameters into a
|
||||
# space-separated string is a well documented source of bugs and security
|
||||
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||
# options in "$@", and eventually passing that to Java.
|
||||
#
|
||||
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||
# see the in-line comments for details.
|
||||
#
|
||||
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||
# Darwin, MinGW, and NonStop.
|
||||
#
|
||||
# (3) This script is generated from the Groovy template
|
||||
# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
|
||||

# Asset Transfer Basic typescript HSM sample
|
||||
|
||||
This sample takes the Asset Transfer basic example and re-works it to focus on how
|
||||
you would use a Hardware Security Modules within your node client application.
|
||||
|
||||
## About the Sample
|
||||
|
||||
This typescript sample application is able to use any of the asset transfer basic
|
||||
chaincode samples. It will show how to register users with a Fabric CA and enroll users which will store keys in an HSM (In this case the sample uses SoftHSM which is an HSM implementation that should be used for development and testing purposes only). It also demonstrates setting up a wallet that will store identities that can then be used to transact on the fabric network which are HSM managed.
|
||||
|
||||
## C Compilers
|
||||
|
||||
In order for the client application to run successfully you must ensure you have C compilers and Python 3 (Note that Python 2 may still work however Python 2 is out of support and could stop working in the future) installed otherwise the node dependency `pkcs11js` will not be built and the application will fail. The failure will look like
|
||||
|
||||
```
|
||||
Loaded the network configuration located at /home/dave/temp/fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/connection-org1.json
|
||||
******** FAILED to run the application: Error: Cannot find module 'pkcs11js'
|
||||
Require stack:
|
||||
- /home/dave/temp/fabric-samples/asset-transfer-basic/application-typescript-hsm/node_modules/fabric-common/lib/impl/bccsp_pkcs11.js
|
||||

||||

|
||||
- /home/dave/temp/fabric-samples/asset-transfer-basic/application-typescript-hsm/dist/app.js
|
||||
```
|
||||
|
||||
how to install the required C Compilers and Python will depend on your operating system and version.
|
||||
|
||||
## Configuring and running a Hardware Security Module
|
||||
|
||||
This sample sets the hsmOptions for the wallet as follows
|
||||
|
||||
```javascript
|
||||
const softHSMOptions: HsmOptions = {
|
||||
lib: await findSoftHSMPKCS11Lib(),
|
||||
pin: process.env.PKCS11_PIN || '98765432',
|
||||
label: process.env.PKCS11_LABEL || 'ForFabric',
|
||||
};
|
||||
```
|
||||
|
||||
which is specific to using SoftHSM which has been initialised with a token labelled `ForFabric`
|
||||
and a user pin of `98765432`, however you can override these values to use your own HSM by either
|
||||
editting the application or use these environment variables to pass in the values:
|
||||
|
||||
* PKCS11_LIB - path to the your specific HSM Library
|
||||
* PKCS11_PIN - your HSM pin
|
||||
* PKCS11_LABEL - your HSM label
|
||||
|
||||
Alternatively you could install SoftHSM to try out the application as described in the next sections
|
||||
|
||||
### Install SoftHSM
|
||||
|
||||
In order to run the application in the absence of a real HSM, a software
|
||||
emulator of the PKCS#11 interface is required.
|
||||
For more information please refer to [SoftHSM](https://www.opendnssec.org/softhsm/).
|
||||
|
||||
SoftHSM can either be installed using the package manager for your host system:
|
||||
|
||||
* Ubuntu: `sudo apt install softhsm2`
|
||||
* macOS: `brew install softhsm`
|
||||
* Windows: **unsupported**
|
||||
|
||||
Or compiled and installed from source:
|
||||
|
||||
1. install openssl 1.0.0+ or botan 1.10.0+
|
||||
2. download the source code from <https://dist.opendnssec.org/source/softhsm-2.5.0.tar.gz>
|
||||
3. `tar -xvf softhsm-2.5.0.tar.gz`
|
||||
4. `cd softhsm-2.5.0`
|
||||
5. `./configure --disable-gost` (would require additional libraries, turn it off unless you need 'gost' algorithm support for the Russian market)
|
||||
6. `make`
|
||||
7. `sudo make install`
|
||||
|
||||
### Specify the SoftHSM configuration file
|
||||
|
||||
A configuration file for SoftHSM is provided in this sample directory. This file
|
||||
uses /tmp as the location for SoftHSM to store it's data which means (depending on
|
||||
your operating system configuration) the data could be deleted at some point, for example
|
||||
when you reboot your system. If this data is lost then you will have to delete the wallet
|
||||
created. An alternative is to change this file to store SoftHSM data in a permanent location
|
||||
on your file system.
|
||||
To use this configuration file you need to export an environment variable to point to it
|
||||
for example, if you are in the application directory then you can use the following command
|
||||
|
||||
```bash
|
||||
export SOFTHSM2_CONF=$PWD/softhsm2.conf
|
||||
```
|
||||
|
||||
Ensure you have this set when initializing the token as well as running the application
|
||||
|
||||
### Initialize a token to store keys in SoftHSM
|
||||
|
||||
If you have not initialized a token previously (or it has been deleted) then you will need to perform this one time operation
|
||||
|
||||
```bash
|
||||
softhsm2-util --init-token --slot 0 --label "ForFabric" --pin 98765432 --so-pin 1234
|
||||
```
|
||||
|
||||
The Security Officer PIN, specified with the `--so-pin` flag, can be used to re-initialize the token,
|
||||
and the user PIN (see below), specified with the `--pin` flag, is used by applications to access the token for
|
||||
generating and retrieving keys.
|
||||
|
||||
## Running the sample
|
||||
|
||||
Use the Fabric test network utility (`network.sh`) to start a Fabric network and deploy one
|
||||
one of the sample chaincodes.
|
||||
|
||||
Follow these step in order.
|
||||
- Start the test network with a Certificate Authority and create a channel, so assuming you are in the ensuring you are in the `application-typescript-hsm` directory
|
||||
|
||||
```
|
||||
cd ../../test-network
|
||||
./network.sh down
|
||||
./network.sh up createChannel -c mychannel -ca
|
||||
```
|
||||
|
||||
- Deploy the chaincode (smart contract)
|
||||
|
||||
```
|
||||
# to deploy the javascript version
|
||||
./network.sh deployCC -ccs 1 -ccv 1 -ccep "OR('Org1MSP.peer','Org2MSP.peer')" -ccl javascript -ccp ./../asset-transfer-basic/chaincode-javascript/ -ccn basic
|
||||
```
|
||||
|
||||
- Run the application
|
||||
|
||||
```
|
||||
cd ../asset-transfer-basic/application-typescript-hsm
|
||||
npm install
|
||||
npm run build
|
||||
node dist/app.js
|
||||
```
|
||||
|
||||
### Expected successful execution
|
||||
|
||||
If the sample runs successfully then it will output several messages showing the various actions and finally display the message
|
||||
|
||||
```
|
||||
*** The sample ran successfully ***
|
||||
```
|
||||
|
||||
One the first run of the sample, a CA admin id from Org1 will be enrolled from the CA. The certificate for this admin will be stored in the application wallet but the private key will have been stored in the HSM, it will not be in the application wallet. A User in Org1 will be registered in the the Org1 CA and then enrolled. Again only it's certificate will be stored in the application wallet.
|
||||
All signing of transactions done by the application (driven by the node sdk) will actually be done by the HSM rather than within the node sdk as the private key will never be directly available outside of the HSM.
|
||||
|
||||
This sample can be run multiple times even while the same network remains up. As the certificates are already in the application wallet it will not have to enroll a CA admin or register and enroll a user.
|
||||
|
||||
### Possible issues you could encounter running the sample
|
||||
|
||||
If you see this error:
|
||||
|
||||
```
|
||||
******** FAILED to run the application: Pkcs11Error: CKR_GENERAL_ERROR
|
||||
```
|
||||
Make sure you have exported SOFTHSM2_CONF correctly and it points to a valid SoftHSM configuration file that references
|
||||
a directory containing a initialised SoftHSM token
|
||||
|
||||
|
||||
If you see this error:
|
||||
|
||||
```
|
||||
2020-08-07T20:23:17.590Z - error: [DiscoveryService]: send[mychannel] - Channel:mychannel received discovery error:access denied
|
||||
******** FAILED to run the application: Error: DiscoveryService: mychannel error: access denied
|
||||
```
|
||||
|
||||
Then the current certificates in your wallet are not valid for the network you are trying to interact with. This would happen if you had
|
||||
shutdown the fabric network using `network.sh down` and created a new network because this causes all the root certificates to be recreated
|
||||
To address this problem, you can delete the `wallet` directory in the `dist` folder (`fabric-samples/asset-transfer-basic/application-typescript-hsm/dist/wallet`) of this sample to create new certificates. Because new keypairs are generated these will be stored in SoftHSM and the existing old ones will not be referenced
|
||||
|
||||
If you see this error
|
||||
|
||||
```
|
||||
Failed to register user : Error: fabric-ca request register failed with errors [[ { code: 20, message: 'Authentication failure' } ]]
|
||||
******** FAILED to run the application: Error: Identity not found in wallet: appUser
|
||||
```
|
||||
|
||||
Then the most likely cause is you have deleted your wallet. You would need to either
|
||||
- stop and create a new fabric network using the `network.sh down` and then following the above instructions to start a new fabric network (but you should not re-initialize the softhsm token)
|
||||
- or change the application such that it registers a new user instead of `appUser`. This is because be default a registered user can only be enrolled once (using the userid and it's secret)
|
||||
|
||||
If you see this error
|
||||
|
||||
```
|
||||
******** FAILED to run the application: Error: _pkcs11OpenSession[336]: PKCS11 label ForFabric cannot be found in the slot list
|
||||
```
|
||||
|
||||
Then the SoftHSM token directory has been deleted (could be due to the /tmp file being cleaned up if you use the sample softhsm2.conf file provided).
|
||||
You will either need to
|
||||
- delete your existing wallet, bring down the network as described in `Clean up` section and recreate the network including re-initializing the softhsm token
|
||||
- or you could just re-initialise the softhsm token but you will need to change the application so that it registers a new user instead of `appUser`
|
||||
|
||||
If you see this error (note the number following `SKI` will not be the same)
|
||||
|
||||
```
|
||||
******** FAILED to run the application: Error: _pkcs11SkiToHandle[572]: no key with SKI 27f3557183cd5f26384ab69968ba74944c94c0e24f681c4fadd6502886891da0 found
|
||||
```
|
||||
|
||||
Then the certificates in your wallet do not have corresponding keys in SoftHSM. You can should bring down the network and delete your current wallet (as described in `Clean up` section) and create the network again
|
||||
|
||||
|
||||
If you see either of these errors when the application ends
|
||||
|
||||

||||

|
||||
Aborted (core dumped)
|
||||
```
|
||||
|
||||
then this is due to a bug in `node`. May sure you are using the latest supported version of node, however at the time of writing (node 14.17.1 & node 12.22.1) a fix had not been released by node.js
|
||||
|
||||
### Enabling Node SDK logging
|
||||
|
||||
To see the SDK workings, try setting the logging to show on the console before running
|
||||
```
|
||||
export HFC_LOGGING='{"debug":"console"}'
|
||||
```
|
||||
or log to a file
|
||||
```
|
||||
export HFC_LOGGING='{"debug":"./debug.log"}'
|
||||
```
|
||||
|
||||
## Clean up
|
||||
|
||||
When you are finished, you can bring down the test network.
|
||||
The command will remove all the nodes of the test network, and delete any
|
||||
ledger data that you created:
|
||||
|
||||
```bash
|
||||
cd ../../test-network
|
||||
./network.sh down
|
||||
```
|
||||
Be sure to delete the wallet directory create by the application.
|
||||
The stored identities will no longer be valid when restarting the network.
|
||||
For example if you are in the application-typescript-hsm directory
|
||||
|
||||
```bash
|
||||
rm -fr dist/wallet
|
||||
```
|
||||
|
||||
## Suggestions
|
||||
When typescript node applications log problems or terminate with a stack trace you normally would have to look at the compiled .js code to find the code that was executed in the stack trace. It would be easier if you could find the corresponding lines in the typescript source file. One solution to this problem can be found here https://github.com/evanw/node-source-map-support which will convert stack trace output to corresponding typescript file lines using the generated source maps.

# Off Chain data
|
||||
|
||||
This sample demonstrates how you can use [Peer channel-based event services](https://hyperledger-fabric.readthedocs.io/en/latest/peer_event_services.html)
|
||||
to replicate the data on your blockchain network to an off chain database.
|
||||
Using an off chain database allows you to analyze the data from your network or
|
||||
build a dashboard without degrading the performance of your application.
|
||||
|
||||
This sample uses the [Fabric network event listener](https://hyperledger.github.io/fabric-sdk-node/release-1.4/tutorial-channel-events.html) from the Node.JS Fabric SDK to write data to local instance of
|
||||
CouchDB.
|
||||
|
||||
## Getting started
|
||||
|
||||
This sample uses Node Fabric SDK application code to connect to a running instance
|
||||
of the Fabric test network. Make sure that you are running the following
|
||||
commands from the `off_chain_data/legacy-javascript` directory.
|
||||
|
||||
### Starting the Network
|
||||
|
||||
Use the following command to start the sample network:
|
||||
|
||||
```
|
||||
./startFabric.sh
|
||||
```
|
||||
|
||||
This command will deploy an instance of the Fabric test network. The network
|
||||
consists of an ordering service, two peer organizations with one peers each, and
|
||||
a CA for each org. The command also creates a channel named `mychannel`. The
|
||||
`asset-transfer-basic` chaincode will be installed on both peers and deployed to
|
||||
the channel.
|
||||
|
||||
### Configuration
|
||||
|
||||
The configuration for the listener is stored in the `config.json` file:
|
||||
|
||||
```
|
||||
{
|
||||
"peer_name": "peer0.org1.example.com",
|
||||
"channelid": "mychannel",
|
||||
"use_couchdb":true,
|
||||
"create_history_log":true,
|
||||
"couchdb_address": "http://admin:password@localhost:5990"
|
||||
}
|
||||
```
|
||||
|
||||
`peer_name:` is the target peer for the listener.
|
||||
`channelid:` is the channel name for block events.
|
||||
`use_couchdb:` If set to true, events will be stored in a local instance of
|
||||
CouchDB. If set to false, only a local log of events will be stored.
|
||||
`create_history_log:` If true, a local log file will be created with all of the
|
||||
block changes.
|
||||
`couchdb_address:` is the local address for an off chain CouchDB database with username and password.
|
||||
|
||||
### Create an instance of CouchDB
|
||||
|
||||
If you set the "use_couchdb" option to true in `config.json`, you can run the
|
||||
following command start a local instance of CouchDB using docker:
|
||||
|
||||
```
|
||||
docker run -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password --publish 5990:5984 --detach --name offchaindb couchdb:3.2.2
|
||||
docker start offchaindb
|
||||
```
|
||||
|
||||
|
||||
### Install dependencies
|
||||
|
||||
You need to install Node.js version 8.9.x to use the sample application code.
|
||||
Execute the following commands to install the required dependencies:
|
||||
|
||||
```
|
||||
npm install
|
||||
```
|
||||
|
||||
### Starting the Channel Event Listener
|
||||
|
||||
After we have installed the application dependencies, we can use the Node.js SDK
|
||||
to create the identity our listener application will use to interact with the
|
||||
network. Run the following command to enroll the admin user:
|
||||
```
|
||||
node enrollAdmin.js
|
||||
```
|
||||
|
||||
You can then run the following command to register and enroll an application
|
||||
user:
|
||||
|
||||
```
|
||||
node registerUser.js
|
||||
```
|
||||
|
||||
We can then use our application user to start the block event listener:
|
||||
|
||||
```
|
||||
node blockEventListener.js
|
||||
```
|
||||
|
||||
If the command is successful, you should see the output of the listener reading
|
||||
the configuration blocks of `mychannel` in addition to the blocks that recorded
|
||||
the approval and commitment of the assets chaincode definition.
|
||||
|
||||
`blockEventListener.js` creates a listener named "offchain-listener" on the
|
||||
channel `mychannel`. The listener writes each block added to the channel to a
|
||||
processing map called BlockMap for temporary storage and ordering purposes.
|
||||
`blockEventListener.js` uses `nextblock.txt` to keep track of the latest block
|
||||
that was retrieved by the listener. The block number in `nextblock.txt` may be
|
||||
set to a previous block number in order to replay previous blocks. The file
|
||||
may also be deleted and all blocks will be replayed when the block listener is
|
||||
started.
|
||||
|
||||
`BlockProcessing.js` runs as a daemon and pulls each block in order from the
|
||||
BlockMap. It then uses the read-write set of that block to extract the latest
|
||||
key value data and store it in the database. The configuration blocks of
|
||||
mychannel did not any data to the database because the blocks did not contain a
|
||||
read-write set.
|
||||
|
||||
The channel event listener also writes metadata from each block to a log file
|
||||
defined as channelid_chaincodeid.log. In this example, events will be written to
|
||||
a file named `mychannel_basic.log`. This allows you to record a history of
|
||||
changes made by each block for each key in addition to storing the latest value
|
||||
of the world state.
|
||||
|
||||
**Note:** Leave the blockEventListener.js running in a terminal window. Open a
|
||||
new window to execute the next parts of the demo.
|
||||
|
||||
### Generate data on the blockchain
|
||||
|
||||
Now that our listener is setup, we can generate data using the assets chaincode
|
||||
and use our application to replicate the data to our database. Open a new
|
||||
terminal and navigate to the `fabric-samples/off_chain_data/legacy-javascript` directory.
|
||||
|
||||
You can use the `addAssets.js` file to add random sample data to blockchain.
|
||||
The file uses the configuration information stored in `addAssets.json` to
|
||||
create a series of assets. This file will be created during the first execution
|
||||
of `addAssets.js` if it does not exist. This program can be run multiple times
|
||||
without changing the properties. The `nextAssetNumber` will be incremented and
|
||||
stored in the `addAssets.json` file.
|
||||
|
||||
```
|
||||
{
|
||||
"nextAssetNumber": 100,
|
||||
"numberAssetsToAdd": 20
|
||||
}
|
||||
```
|
||||
|
||||
Open a new window and run the following command to add 20 assets to the
|
||||
blockchain:
|
||||
|
||||
```
|
||||
node addAssets.js
|
||||
```
|
||||
|
||||
After the assets have been added to the ledger, use the following command to
|
||||
transfer one of the assets to a new owner:
|
||||
|
||||
```
|
||||
node transferAsset.js asset110 james
|
||||
```
|
||||
|
||||
Now run the following command to delete the asset that was transferred:
|
||||
|
||||
```
|
||||
node deleteAsset.js asset110
|
||||
```
|
||||
|
||||
## Offchain CouchDB storage:
|
||||
|
||||
If you followed the instructions above and set `use_couchdb` to true,
|
||||
`blockEventListener.js` will create two tables in the local instance of CouchDB.
|
||||
`blockEventListener.js` is written to create two tables for each channel and for
|
||||
each chaincode.
|
||||
|
||||
The first table is an offline representation of the current world state of the
|
||||
blockchain ledger. This table was created using the read-write set data from
|
||||
the blocks. If the listener is running, this table should be the same as the
|
||||
latest values in the state database running on your peer. The table is named
|
||||
after the channelid and chaincodeid, and is named mychannel_basic in this
|
||||
example. You can navigate to this table using your browser:
|
||||
http://127.0.0.1:5990/mychannel_basic/_all_docs
|
||||
|
||||
A second table records each block as a historical record entry, and was created
|
||||
using the block data that was recorded in the log file. The table name appends
|
||||
history to the name of the first table, and is named mychannel_basic_history
|
||||
in this example. You can also navigate to this table using your browser:
|
||||
http://127.0.0.1:5990/mychannel_basic_history/_all_docs
|
||||
|
||||
### Configure a map/reduce view for summarizing counts of assets by color:
|
||||
|
||||
Now that we have state and history data replicated to tables in CouchDB, we
|
||||
can use the following commands query our off-chain data. We will also add an
|
||||
index to support a more complex query. Note that if the `blockEventListener.js`
|
||||
is not running, the database commands below may fail since the database is only
|
||||
created when events are received.
|
||||
|
||||
Open a new terminal window and execute the following:
|
||||
|
||||
```
|
||||
curl -X PUT http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign -d '{"views":{"colorview":{"map":"function (doc) { emit(doc.color, 1);}","reduce":"function ( keys , values , combine ) {return sum( values )}"}}}' -H 'Content-Type:application/json'
|
||||
```
|
||||
|
||||
Execute a query to retrieve the total number of assets (reduce function):
|
||||
|
||||
```
|
||||
curl -X GET http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign/_view/colorview?reduce=true
|
||||
```
|
||||
|
||||
If successful, this command will return the number of assets in the blockchain
|
||||
world state, without having to query the blockchain ledger:
|
||||
|
||||
```
|
||||
{"rows":[
|
||||
{"key":null,"value":19}
|
||||
]}
|
||||
```
|
||||
|
||||
Execute a new query to retrieve the number of assets by color (map function):
|
||||
|
||||
```
|
||||
curl -X GET http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign/_view/colorview?group=true
|
||||
```
|
||||
|
||||
The command will return a list of assets by color from the CouchDB database.
|
||||
|
||||
```
|
||||
{"rows":[
|
||||
{"key":"blue","value":2},
|
||||
{"key":"green","value":2},
|
||||
{"key":"purple","value":3},
|
||||
{"key":"red","value":4},
|
||||
{"key":"white","value":6},
|
||||
{"key":"yellow","value":2}
|
||||
]}
|
||||
```
|
||||
|
||||
To run a more complex command that reads through the block history database, we
|
||||
will create an index of the blocknumber, sequence, and key fields. This index
|
||||
will support a query that traces the history of each asset. Execute the
|
||||
following command to create the index:
|
||||
|
||||
```
|
||||
curl -X POST http://127.0.0.1:5990/mychannel_basic_history/_index -d '{"index":{"fields":["blocknumber", "sequence", "key"]},"name":"asset_history"}' -H 'Content-Type:application/json'
|
||||
```
|
||||
|
||||
Now execute a query to retrieve the history for the asset we transferred and
|
||||
then deleted:
|
||||
|
||||
```
|
||||
curl -X POST http://127.0.0.1:5990/mychannel_basic_history/_find -d '{"selector":{"key":{"$eq":"asset110"}}, "fields":["blocknumber","is_delete","value"],"sort":[{"blocknumber":"asc"}, {"sequence":"asc"}]}' -H 'Content-Type:application/json'
|
||||
```
|
||||
|
||||
You should see the transaction history of the asset that was created,
|
||||
transferred, and then removed from the ledger.
|
||||
|
||||
```
|
||||
{"docs":[
|
||||
{"blocknumber":12,"is_delete":false,"value":"{\"docType\":\"asset\",\"name\":\"asset110\",\"color\":\"blue\",\"size\":60,\"owner\":\"debra\"}"},
|
||||
{"blocknumber":22,"is_delete":false,"value":"{\"docType\":\"asset\",\"name\":\"asset110\",\"color\":\"blue\",\"size\":60,\"owner\":\"james\"}"},
|
||||
{"blocknumber":23,"is_delete":true,"value":""}
|
||||
]}
|
||||
```
|
||||
|
||||
## Getting historical data from the network
|
||||
|
||||
You can also use the `blockEventListener.js` program to retrieve historical data
|
||||
from your network. This allows you to create a database that is up to date with
|
||||
the latest data from the network or recover any blocks that the program may
|
||||
have missed.
|
||||
|
||||
If you ran through the example steps above, navigate back to the terminal window
|
||||
where `blockEventListener.js` is running and close it. Once the listener is no
|
||||
longer running, use the following command to add 20 more assets to the
|
||||
ledger:
|
||||
|
||||
```
|
||||
node addAssets.js
|
||||
```
|
||||
|
||||
The listener will not be able to add the new assets to your CouchDB database.
|
||||
If you check the current state table using the reduce command, you will only
|
||||
be able to see the original assets in your database.
|
||||
|
||||
```
|
||||
curl -X GET http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign/_view/colorview?reduce=true
|
||||
```
|
||||
|
||||
To add the new data to your off-chain database, remove the `nextblock.txt`
|
||||
file that kept track of the latest block read by `blockEventListener.js`:
|
||||
|
||||
```
|
||||
rm nextblock.txt
|
||||
```
|
||||
|
||||
You can new re-run the channel listener to read every block from the channel:
|
||||
|
||||
```
|
||||
node blockEventListener.js
|
||||
```
|
||||
|
||||
This will rebuild the CouchDB tables and include the 20 assets that have been
|
||||
added to the ledger. If you run the reduce command against your database one
|
||||
more time,
|
||||
|
||||
```
|
||||
curl -X GET http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign/_view/colorview?reduce=true
|
||||
```
|
||||
|
||||
you will be able to see that all of the assets have been added to your
|
||||
database:
|
||||
|
||||
```
|
||||
{"rows":[
|
||||
{"key":null,"value":39}
|
||||
]}
|
||||
```
|
||||
|
||||
## Clean up
|
||||
|
||||
If you are finished using the sample application, you can bring down the network
|
||||
and any accompanying artifacts by running the following command:
|
||||
```
|
||||
./network-clean.sh
|
||||
```
|
||||
|
||||
Running the script will complete the following actions:
|
||||
|
||||
* Bring down the Fabric test network.
|
||||
* Takes down the local CouchDB database.
|
||||
* Remove the certificates you generated by deleting the `wallet` folder.
|
||||
* Delete `nextblock.txt` so you can start with the first block next time you
|
||||
operate the listener.
|
||||
* Removes `addAssets.json`.

blockEventListener.js is an nodejs application to listen for block events from

"channelid": "mychannel",

|

}
|

|

peer_name: target peer for the listener
|
||||
channelid: channel name for block events
|
||||
use_couchdb: if set to true, events will be stored in a local couchdb
|
||||
couchdb_address: local address for an off chain couchdb database
|
||||
|
||||
Note: If use_couchdb is set to false, only a local log of events will be stored.
|
||||
|
||||
Usage:
|
||||
|
||||
node bockEventListener.js
|
||||
|
||||
The block event listener will log events received to the console and write event blocks to
|
||||
a log file based on the channelid and chaincode name.
|
||||
|
||||
The event listener stores the next block to retrieve in a file named nextblock.txt. This file
|
||||
is automatically created and initialized to zero if it does not exist.
