Hyperledger之 Fabric0.6（ 上）

1、安装docker

#curl -fsSL https://get.docker.com/ | sh
#service docker start
#service docker status

安装加速器
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://88b7691f.m.daocloud.io

安装docker
curl -sSL https://get.daocloud.io/docker | sh

设置随机启动
systemctl enable docker

安装docker-compose

docker-compose -f 4-peers-with-membersrvc.yml up|down

4、测试

docker exec -it pbft_vp0_1 bash

root@vp0:/opt/gopath/src/github.com/hyperledger/fabric# peer network login jim -p 6avZQLwcUe9b
09:41:09.300 [networkCmd] networkLogin -> INFO 001 CLI client login...

09:41:17.326 [main] main -> INFO 006 Exiting.....

5、部署链码

cd /opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go

mkdir chaincode_example06

cd chaincode_example06

wget https://raw.githubusercontent.com/IBM-Blockchain/learn-chaincode/master/finished/chaincode_finished.go

mv chaincode_finished.go chaincode_example06.go

peer chaincode deploy -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example06 -c '{"Function":"init","Args":["ancun"]}' -u jim


09:46:38.363 [chaincodeCmd] getChaincodeSpecification -> INFO 001 Local user 'jim' is already logged in. Retrieving login token.
09:46:41.898 [chaincodeCmd] chaincodeDeploy -> INFO 002 Deploy result: type:GOLANG chaincodeID:<path:"github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example06" name:"a551e00fec9b30a1d47996cf50fe45d82e045d5f40c3ea1f3e5559bdda8a9f23b6e2d3d07c772e50e69b1f00628a883f2f658369d5619f82c01f79d1c6ce2cff" > ctorMsg:<args:"init" args:"ancun" > 
Deploy chaincode: a551e00fec9b30a1d47996cf50fe45d82e045d5f40c3ea1f3e5559bdda8a9f23b6e2d3d07c772e50e69b1f00628a883f2f658369d5619f82c01f79d1c6ce2cff
09:46:41.899 [main] main -> INFO 003 Exiting.....

6、执行调用
POST http://xx.xx.xx.xx:7050/chaincode

{
  "jsonrpc": "2.0",
  "method": "invoke",
  "params": {
    "type": 1,
    "chaincodeID": {
      "name": "上一步返回的链码ID"
    },
    "ctorMsg": {
      "function": "write",
      "args": [
        "hash",
        "xyz"
      ]
    },
    "secureContext": "jim"
  },
  "id": 2
}

这里通过调用 write 函数写入 key=hash,value=xyz。
示例响应内容：

{
    "jsonrpc": "2.0",
    "result": {
        "status": "OK",
        "message": "73304d46-5677-4ba9-9020-02f618a494d4"
    },
    "id": 2
}

7、查询

{
  "jsonrpc": "2.0",
  "method": "query",
  "params": {
    "type": 1,
    "chaincodeID": {
      "name": "上一步返回的链码ID"
    },
    "ctorMsg": {
      "function": "read",
      "args": [
        "hash"
      ]
    },
    "secureContext": "jim"
  },
  "id": 0
}

示例响应：

{
    "jsonrpc": "2.0",
    "result": {
        "status": "OK",
        "message": "xyz"
    },
    "id": 0
}

更多使用方法，可以参考 API 文档。

###########                  Python客户端            #########
##############################################################

yum -y install python-pip
No package python-pip available.
Error: Nothing to do
说没有python-pip软件包可以安装。
这是因为像centos这类衍生出来的发行版，他们的源有时候内容更新的比较滞后，或者说有时候一些扩展的源根本就没有。
所以在使用yum来search  python-pip的时候，会说没有找到该软件包。因此为了能够安装这些包，需要先安装扩展源EPEL。
yum -y install epel-release
安装完之后别忘了清除一下cache
yum clean all

pip --version
pip install --upgrade pip
