It's a sample project for how to use fabric-sdk-go to use chaincode.

Directorys:

• config: config files of fabric network
• cli: codes to use chaincode

• write sdk config.yaml for byfn
• chaincode source code
• struct used for sdk operations
• get fabsdk
• install chaincode to a target peer
• instantiate chaincode
• invoke chaincode
• query chaincode
• upgrade chaincode's policy
• invoke chaincode with new policy
• query chaincode agian
• fetch chaincode information, policy included

1. Clone fabric-samples into your $GOPATH, and fabric-sdk-go-sample into a workspace not in you $GOPATH.

   cd $GOPATH/src/github.com/hyperledger
   git clone [email protected]:hyperledger/fabric-samples.git
   
   
   cd ~
   git clone [email protected]:Shitaibin/fabric-sdk-go-sample.git
   

2. Start byfn

   cd $GOPATH/src/github.com/hyperledger/fabric-samples/first-network
   ./byfn.sh up
   

   

3. Modify config.yaml files. All config files in config directory, replace /Users/shitaibin/go/src/github.com/hyperledger/fabric-samples/first-network/crypto-config to ${GOPATH}/src/github.com/hyperledger/fabric-samples/first-network/crypto-config, ${GOPAHT} is your real GOPATH.

4. Run chaincode sample by go run main.go，to instantiate a new chaincode and upgrade it.

5. Run event sample:

   $ cd fabric-sdk-go-sample/samples/event
   $ go run main.go
