Fabric sdk go sample
==========

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

## TODOs

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


## Quick start

1. Clone [fabric-samples](https://github.com/hyperledger/fabric-samples) into
 your $GOPATH, and [fabric-sdk-go-sample](https://github.com/Shitaibin/fabric-sdk-go-sample) into a workspace not in you $GOPATH.
    ```
    cd $GOPATH/src/github.com/hyperledger
    git clone git@github.com:hyperledger/fabric-samples.git
    
    
    cd ~
    git clone git@github.com:Shitaibin/fabric-sdk-go-sample.git
    ```
1. Start byfn

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

1. 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.  
    
1. Run this sample by `go run main.go`，to instantiate a new chaincode and 
upgrade it.
