# Asset Transfer REST API Sample
|
||||
|
||||
This is a simple REST server written in golang with endpoints for chaincode invoke and query.
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
- Setup fabric test network and deploy the asset transfer chaincode by [following this instructions](https://hyperledger-fabric.readthedocs.io/en/release-2.4/test_network.html).
|
||||
|
||||
- cd into rest-api-go directory
|
||||
- Download required dependencies using `go mod download`
|
||||
- Run `go run main.go` to run the REST server
|
||||
|
||||
## Sending Requests
|
||||
|
||||
Invoke endpoint accepts POST requests with chaincode function and arguments. Query endpoint accepts get requests with chaincode function and arguments.
|
||||
|
||||
Sample chaincode invoke for the "createAsset" function. Response will contain transaction ID for a successful invoke.
|
||||
|
||||
``` sh
|
||||
curl --request POST \
|
||||
--url http://localhost:3000/invoke \
|
||||
--header 'content-type: application/x-www-form-urlencoded' \
|
||||
--data = \
|
||||
--data channelid=mychannel \
|
||||
--data chaincodeid=basic \
|
||||
--data function=createAsset \
|
||||
--data args=Asset123 \
|
||||
--data args=yellow \
|
||||
--data args=54 \
|
||||
--data args=Tom \
|
||||
--data args=13005
|
||||
```
|
||||
Sample chaincode query for getting asset details.
|
||||
|
||||
``` sh
|
||||
curl --request GET \
|
||||
--url 'http://localhost:3000/query?channelid=mychannel&chaincodeid=basic&function=ReadAsset&args=Asset123'
|
||||
```
