简介
IBM Bluemix (http://www.ibm.com/bluemix)是一个基于 cloud 的应用开发和部署平台，提供包括多种服务和运行环境的支持。对 Hyperledger 应用开发者而言，IBM Bluemix 提供免费的入门级区块运行环境。本文介绍了在 IBM Bluemix 上部署 Hyperledger 应用的基本过程。
第一步：在 Bluemix 中选择区块服务
登录 Bluemix 后，在 Catalog 页面中选择 Application Services 下的 Blochain 服务。
确认区块服务的名称，然后点击 Create 按钮以创建区块服务。
在新建的区块服务页面上点击 LAUNCH 按钮以启动区块服务，并显示其具体信息。
第二步：在 Bluemix 区块服务中注册用户
首先在区块服务页面中选择 APIs，然后展开 Network's Enroll IDs 列表以获取预置的用户名和密码列表。
然后向选定的区块节点发送如下请求以注册用户
POST https://e1bb641577f249a88acca04da0272249-vp3.us.blockchain.ibm.com:444/registrar
Content-Type: application/json
{"enrollId": "admin",
"enrollSecret": "19725f3d88"
}注册成功的响应为
{"OK": "Login successful for user'admin'."
} 第三步：在 Bluemix 区块服务中发布应用代码，前提是应用的 GoLang 代码必须在 github.com 上。
POST https://e1bb641577f249a88acca04da0272249-vp3.us.blockchain.ibm.com:444/chaincode
Content-Type: application/json
{"jsonrpc": "2.0",
"method": "deploy",
"params": {"type": 1,
"chaincodeID": {"path": "https://github.com/huyouhengbc/Hyperledger/HelloWorld"
},
"ctorMsg": {"function": "init",
"args": []},
"secureContext": "admin"
},
"id": 1
}发布成功的响应为
{"jsonrpc": "2.0",
"result": {"status": "OK",
"message": "e2623e76371a16ca86d97bfb90bdab95885939bf4f2fa40133d65bca4aace27eaf94d8cd10438b80de097442916f6bfef87fb45a6cd678e3cb6ec0bd8dd008c2"
},
"id": 1
}第四步：测试应用代码，
Query 请求
POST https://e1bb641577f249a88acca04da0272249-vp3.us.blockchain.ibm.com:444/chaincode
Content-Type: application/json
{"jsonrpc": "2.0",
"method": "query",
"params": {"type": 1,
"chaincodeID": {"name": "e2623e76371a16ca86d97bfb90bdab95885939bf4f2fa40133d65bca4aace27eaf94d8cd10438b80de097442916f6bfef87fb45a6cd678e3cb6ec0bd8dd008c2"
},
"ctorMsg": {"function": "hello",
"args": []},
"secureContext": "admin"
},
"id": 3
}Query 响应

{"jsonrpc":"2.0","result":{"status":"OK","message":"d74495ff-f3d3-44ba-acc6-5fbc767bbf21"},"id":3}后记
- 发布应用代码中的 path 指向的是 GoLang 代码所在的目录，而不是 GoLang 源码文件，错误响应如下：

Content-Type: application/json
{"jsonrpc": "2.0",

{"jsonrpc": "2.0",
"error": {"code": -32001,
"message": "Deployment failure",
"data": "Error when deploying chaincode: Error getting chaincode package bytes: Error getting code'go get'failed with error:'exit status 2'\n# github.com/huyouhengbc/Hyperledger/HelloWorld\n/go/_usercode_/730749822/src/github.com/huyouhengbc/Hyperledger/HelloWorld/HelloWorld.go:15: undefined: shim.ChaincodeStubInterface\n/go/_usercode_/730749822/src/github.com/huyouhengbc/Hyperledger/HelloWorld/HelloWorld.go:21: undefined: shim.ChaincodeStubInterface\n/go/_usercode_/730749822/src/github.com/huyouhengbc/Hyperledger/HelloWorld/HelloWorld.go:27: undefined: shim.ChaincodeStubInterface\n"
},

}- 发布应用报错
{"jsonrpc": "2.0",
"error": {"code": -32001,
"message": "Deployment failure",
"data": "Error when deploying chaincode: Failed loading TCerts from TCA"
},
"id": 1
}解决方法：在 Demo Chaincoded下发布示例应用，选择 Show API details 输出中使用的节点。
