写在最前
在使用Fabric-SDK-Go@1.0.0操作Fabric网络时遇到了bug。Fabric-SDK-GO的当前版本没有办法在没有系统通道的情况下创建应用通道,而Fabric的最新几个版本允许在没有系统通道的情况下搭建应用通道。为了解决这个矛盾并使用Fabric-SDK-GO完成后续的项目开发,所以只能将Fabric做降级。这里使用的Fabric版本为:2.2.10。
本篇博客不会完整地介绍整个系统通道的搭建过程,这里主要是为了配合使用Fabric-SDK-GO。
这里依然使用前序博文中的finance_network
网络示例来展示应用通道的搭建过程。在使用Fabric2.2搭建该网络时,生成证书及链码链接配置文件的过程可以直接参考博客:https://blog.csdn.net/yeshang_lady/article/details/134113296。 这里就不在赘述了。
1. 创建通道配置文件
在有系统通道的情况下搭建应用通道时,在启动相关docker容器之前,一定要先创建系统通道(应用通道可以等到容器启动之后创建)。所以这里要先创建系统通道配置文件configtx.yaml
,其具体内容如下:

接着,便可以创建系统通道了:
#在finance_network目录下执行
configtxgen -profile TwoOrgsOrdererGenesis -channelID system-channel -outputBlock ./system-genesis-block/genesis.block -configPath ./
如果在启动docker容器之前没有创建系统通道的话,可能会提示如下错误:panic: unable to bootstrap orderer. Error reading genesis block file: read /var/hyperledger/orderer/orderer.genesis.block: is a directory。
出现这种错误是因为在docker配置文件中指定了系统通道文件路径,docker容器会自己创建相关文件。
2. 创建docker配置文件
这里创建compose/compose-withsystem.yaml
文件作为docker容器配置文件,这里要增加系统通道相关的环境变量。文件具体内容如下:

然后启动容器,具体命令如下:
#在finance_network目录下执行
sudo DOCKER_SOCK="/var/run/docker.sock" docker-compose -f compose/compose-withsystem.yaml up -d
创建应用通道及配置锚节点
接下来使用如下命令创建应用通道并配置各个组织的锚节点。文章来源:https://www.toymoban.com/news/detail-812250.html
#创建应用通道
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel
#设置组织Org1的锚节点
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP
#设置组织Org2的锚节点
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP
接下来的peer节点加入通道及部署链码等的操作将使用Fabric-sdk-go来实现,具体参考博客:https://blog.csdn.net/yeshang_lady/article/details/134921528。
Tips:在使用Fabric-SDK-GO进行后续操作的时候,要对docker容器进行重启(注意,只需要重启docker容器)。因为Fabric-SDK-GO会依据我们生成的文件(channel.tx、Org1MSPanchors.tx、Org2MSPanchors.tx)重新进行创建应用通道及配置锚节点等操作。如果不重启,则会提示如下错误: create channel failed: create channel failed: SendEnvelope failed: calling orderer 'orderer.finance.com:7050' failed: Orderer Server Status Code: (400) BAD_REQUEST. Description: error applying config update to existing channel 'mychannel': error authorizing update: error validating ReadSet: proposed update requires that key [Group] /Channel/Application be at version 0, but it is currently at version 1
