This repository contains source code for HTTP server which is able to call the Hyperledger Fabric Chaincode. Both query and invoke operations are supported.

• Fully functional Hyperledger Fabric network
• Prepared Fabric SDK configuration file (see sample)
• Private key of the user which has access to the Hyperledger Fabric network
• Go
• Git
• Make
• Docker Compose

• Clone this repository and cd there

  git clone https://github.com/KompiTech/fabric-sdk-server-go.git && cd fabric-sdk-server-go
  

• Copy user's private key into keystore directory
• Insert Fabric SDK configuration file into config directory and name it sdk_config.yaml (sample can be found in examples)
• Run the Docker Compose

  make compose-up
  

• Try test query (replace fields in [] with your configuration)

  curl "http://localhost:8080/api/v1/chaincode/query?chaincode=[CHAINCODE_NAME]&user=[USER_NAME]&channel=[CHANNEL_NAME]&fcn=[CHAINCODE_FUNCTION]&args=[CHAINCODE_ARGUMENTS]
  

The server itself offers environment variables listed below to set the configuration. This configuration is not needed to override if you're using Docker Compose.

The keystore directory containing user private keys must be placed in CWD from server binary has been started

There are another set of variables used only for running the server in Docker Compose. Those variables don't need to be overriden if you're using default keystore dir and config/sdk_config.yaml as a config file.

This repository contains a Postman collection of request which can be imported to the app for making the requests easier. It contains query and invoke requests with predefined default parameters.

If you're not familiar with Postman, you can give it a try here

This repository contains a file named swagger.json which contains Open API specification of server's API.
