fabric-java-sdk1.3.0 测试End2endIT
2024-04-24 11:16:26
本文描述fabric-java-sdk的End2endIT在阿里云服务器和本地如何测试，测试环境如下：
阿里云服务器centos7.4，安装过程可以参考centos7安装fabric
建议给阿里云服务器配置弹性公网IP，在测试时可以租用按时付费的阿里云以节省费用。按时付费的阿里云在重启服务器后会变更公网IP。

#eclipse版本
Mars.1 Release (4.5.1)
End2endIT实现了如下功能：
- 使用Fabric ca注册和加入用户
- 构造channel
- 安装链码chaincode
- 实例化链码
- 执行链码
- 查询channel中的区块信息
- 链码事件监听器用法
- 遍历区块信息
测试步骤如下：
- 服务器下载fabric-java-sdk并运行fabric.sh脚本启动fabric网络；
- 本地环境eclipse导入fabric-java-sdk，测试End2endIT。
1、启动fabric网络
1.1、下载fabric-java-sdk
#运行前避免被其他fabric干扰，删除运行的docker并附带其镜像
docker rm $(docker ps -aq)
docker rmi -f $(docker images -q)
#执行如下命令确保docker和images清空
docker ps -a
docker images
#我们在/home/yigou路径下新建fabric-1.3.0目录并下载源码，切换到1.3.0
cd /home/yigou
mkdir fabric-1.3.0
cd fabric-1.3.0
git clone https://github.com/hyperledger/fabric-sdk-java.git
cd fabric-sdk-java
git tag
git checkout -b v1.3.0
cd src/test/fixture/sdkintegration
1.2、启动fabric网络
启动网络之前，由于centos7.4的缘故，需要修改docker-compose.yaml文件，在所有environment下面添加如下命令，参考下图。
- GODEBUG=netdns=go
fabric.sh脚本说明
1）脚本命令包含了：./fabric.sh up 强制重新创建网络(默认会启动)。
./fabric.sh start启动
./fabric.sh stop停止
./fabric.sh clean清理生成的docker容器；
实际上fabric.sh只是对docker-compose命令的简单封装。
2）每次使用后，如果重新跑需要执行clean命令清除掉生成的docker容器和其他临时文件。
执行如下命令，启动fabric网络。
fabric.sh up
至此，一个包含1个orderer；4个peer；2个fabric-ca-server的网络（定义在docker-compose.yaml）启动成功，通过如下命令我们可以看到。
[root@bc1 ~]# docker ps -a

如果你想查看某个docker具体的日志，可以通过如下命令查看
#56943fccc47c是CONTAINER ID ，通过docker ps命令可以查看
docker logs --details -f 56943fccc47c
2、运行End2endIT
通过github下载官方源码，导入eclipse中。
需要注意如下两点：
1、如果遇到如下错误，请删除.project和 .classpath 文件再次导入。
Failed to read the project description file (.project) for 'fabric-sdk-java'.
The file has been changed on disk, and it now contains invalid information.
The project will not function properly until the description file is restored to a valid state.
2、修改TestConfig文件中的LOCALHOST，变更为阿里云服务器外网地址。
使用maven，输入test -Dtest=End2endIT（参考下图），运行即可看到程序执行效果。
结果日志：

3、源码分析
3.1、检查配置文件
checkConfig方法，构造测试组织的fabric-ca-client（用于和fabric网络交互的入口）。能够让客户端使用rest风格调用，这样能够注册用户和添加用户
3.2、注册用户并加入
enrollUsersSetup方法将会注册用户并加入组织。该方法为组织org1注册user、admin以及peer(peer用户能够创建channel、加入peer节点、安装chaincode)。
3.3、创建通道
关键代码分析
//调用Channel fooChannel = constructChannel(FOO_CHANNEL_NAME, client, sampleOrg);//定义Channel constructChannel(String name, HFClient client, SampleOrg sampleOrg) throws Exception {//只有peer用户能够创建channelSampleUser peerAdmin = sampleOrg.getPeerAdmin();client.setUserContext(peerAdmin);...//官方工具查看tx文件内容 https://hyperledger-fabric.readthedocs.io/en/release-1.4/commands/configtxgen.html?highlight=.tx//路径位于fabric-sdk-java-master\src\test\fixture\sdkintegration\e2e-2Orgs\v1.3String path = TEST_FIXTURES_PATH + "/sdkintegration/e2e-2Orgs/" + testConfig.getFabricConfigGenVers() + "/" + name + ".tx";//将channel加入peer、orderer，绑定时间监听
}
3.4、安装链码并实例化
关键代码分析
//调用
runChannel(client, fooChannel, true, sampleOrg, 0);//定义
void runChannel(HFClient client, Channel channel, boolean installChaincode, SampleOrg sampleOrg, int delta) {//安装链码Collection<Peer> peers = channel.getPeers();responses = client.sendInstallProposal(installProposalRequest, peers);for (ProposalResponse response : responses) {//查看安装链码的结果 }//实例化链码responses = channel.sendInstantiationProposal(instantiateProposalRequest, channel.getPeers());for (ProposalResponse response : responses) {//查看实例化链码的结果 }//a向b转账100的操作TransactionProposalRequest transactionProposalRequest = client.newTransactionProposalRequest();transactionProposalRequest.setChaincodeID(chaincodeID);transactionProposalRequest.setChaincodeLanguage(CHAIN_CODE_LANG);transactionProposalRequest.setFcn("move");transactionProposalRequest.setProposalWaitTime(testConfig.getProposalWaitTime());transactionProposalRequest.setArgs("a", "b", "100");Collection<ProposalResponse> transactionPropResp = channel.sendTransactionProposal(transactionProposalRequest, channel.getPeers());for (ProposalResponse response : transactionPropResp ) {//查看转账操作的结果 }//验证交易一致性Collection<Set<ProposalResponse>> proposalConsistencySets = SDKUtils.getProposalConsistencySets(transactionPropResp);// 交易信息发送给ordererchannel.sendTransaction(successful).get(testConfig.getTransactionWaitTime(), TimeUnit.SECONDS);// 查询b的值QueryByChaincodeRequest queryByChaincodeRequest = client.newQueryProposalRequest();queryByChaincodeRequest.setArgs(new String[] {"b"});queryByChaincodeRequest.setFcn("query");queryByChaincodeRequest.setChaincodeID(chaincodeID);// 查询channel中区块链高度等信息
}
备注
查看源码和fabric理论有如下几个不一致的地方：
1、实例化链码只需实例化一次，但代码中在所有peer都实例化。
responses = channel.sendInstantiationProposal(instantiateProposalRequest, channel.getPeers());
2、客户端提交交易请求，向需要背书的peer发送请求，获得背书后再发送请求至orderer，orderer再广播至其他peer存储此次交易。
a：代码是向所有peer发送背书请求。修改代码后尝试也是可以的，和背书策略相关。
