Hyperledger Fabric v1.2 中的通道创建失败

Question

我正在尝试使用我自己生成的网络（使用二进制 configtxgen）在 v1.2 中启动一个 Hyperledger Fabric 网络。网络正常启动，无组件提示错误。

但是，当我尝试创建一个新通道时，orderer级别出现错误（以下三种错误之一），没有创建通道。

Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: existing config does not contain element for [Group]  /Channel/Application/Org1MSP but was in the read set

或

Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: existing config does not contain element for [Group]  /Channel/Application but was in the read set

或

Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: existing config does not contain element for [Value]  /Channel/Consortium but was in the read set

为了创建通道，我在 master 分支上使用 Go SDK 并遵循与功能测试相同的过程。

如有任何帮助，我们将不胜感激。

Answer 1

我终于通过更改生成频道的名称成功地通过了这个错误。但是，这并不能解释为什么有些名称不起作用。

Answer 2

我从 JSKIM 得到了解决方案。由于您使用的是 fabric v1.2，因此当排序节点使用创世块启动时，排序节点将创建一个默认通道。

我猜您正在使用 configtxgen 生成您自己的频道工件，但忽略了频道的命名规则。因此，当您的 exec 进入订购者的容器时：

docker exec -it <orderer's container ID> bash

和cd进入chains目录，默认设置为/var/hyperledger/production/orderer/chains。您会注意到已经有一个通道出口。

解决方法如下：

configtxgen -profile testOrgsOrdererGenesis -channelID testchannel -outputBlock ./crypto-config/ordererOrganizations/orderer.block
configtxgen -profile testorgschannel -channelID mychannel-outputCreateChannelTx ./crypto-config/ordererOrganizations/mychannel.tx

当你生成创世块时，使用 channelID 来指定它。或者您可以在创建频道配置事务时重命名您的频道。
