在IBM Bluemix上部署Hyperledger应用
2024-10-13 08:47:05
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
200 OK

Invoke请求

{

},
"ctorMsg": {

}
Invoke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：
POST https://e1bb641577f249a88acca04da0272249-vp0.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/blob/master/HelloWorld/HelloWorld.go"
},
"ctorMsg": {
"function": "init",
"args": [
]
},
"secureContext": "user_type8_0"
},
"id": 1
}

{"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 1'\npackage github.com/huyouhengbc/Hyperledger/blob/master/HelloWorld/HelloWorld.go: cannot find package 'github.com/huyouhengbc/Hyperledger/blob/master/HelloWorld/HelloWorld.go' in any of:\n\t/usr/local/go/src/github.com/huyouhengbc/Hyperledger/blob/master/HelloWorld/HelloWorld.go (from $GOROOT)\n\t/go/_usercode_/234208637/src/github.com/huyouhengbc/Hyperledger/blob/master/HelloWorld/HelloWorld.go (from $GOPATH)\n\t/go/src/github.com/huyouhengbc/Hyperledger/blob/master/HelloWorld/HelloWorld.go\n"},"id":1}
- Bluemix提供基于基于Hyperledger Fabric v0.5的服务，如果使用最新的Hyperledger Fabric接口, 发布应用时错误响应如下：
{
"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"
},
"id": 1
}
- 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。
