Question

在Hyperledger作曲家下，我试图通过多组织设置使用googleauth2.0设置一个持久的Rest服务器。

对于多组织设置，我已关注https://hyperledger.github.io/composer/latest/tutorials/deploy-to-fabric-multi-org，对于谷歌身份验证设置，我已关注https://hyperledger.github.io/composer/latest/tutorials/google_oauth2_rest。

当我尝试使用以下命令为REST服务器启动扩展Docker镜像的新实例时，一切顺利，直到后续步骤

docker run
-d
-e COMPOSER_CARD=${COMPOSER_CARD}
-e COMPOSER_NAMESPACES=${COMPOSER_NAMESPACES}
-e COMPOSER_AUTHENTICATION=${COMPOSER_AUTHENTICATION}
-e COMPOSER_MULTIUSER=${COMPOSER_MULTIUSER}
-e COMPOSER_PROVIDERS="${COMPOSER_PROVIDERS}"
-e COMPOSER_DATASOURCES="${COMPOSER_DATASOURCES}"
-v ~/.composer:/home/composer/.composer
--name rest
--network composer_default
-p 3001:3001
org1/composer-rest-server

以下是来自rest容器的日志：

我已经遇到了其他人收到的错误，因此已经执行了以下额外步骤：

使用以下命令更改〜/ .composer的权限：chmod -R 777~ / .composer
替换了我的网卡connection.json中的IP地址，建议使用0.0.0.0 在https://github.com/hyperledger/composer/issues/3002。

我已经尝试清理所有的docker容器和图像，停止布料并启动布料但是它仍然会出现相同的错误..

预期的行为是命令docker logs -f rest应该在http://localhost:3001/explorer浏览您的REST API完成。但是，它会导致上述错误。

Answer 1

Google Auth教程并不期望从multiorg教程中设置结构，因此如果您按照这些步骤进行操作，则无法正常工作。 Auth教程旨在使用开发结构提供的单一组织来设置编写器开发环境或运行单个组织教程。问题是connection.json需要描述多组织设置（所以你需要一个来自multi-org教程的适当的连接配置文件），并且当你在docker容器中运行你的rest服务器并附加到所有超级分层结构容器连接到您的网络都无法使用主机名和地址（如localhost，127.0.0.1或0.0.0.0）来尝试解决不同的超级分层结构进程（所有这些都会实际请参阅您的休息服务器容器）。您需要使用正确的主机名来识别它们。例如

  订货人
的
orderer.example.com
peer0.org1.example.com for peer0.org1.example.com（与其他同行类似）

org1中的证书颁发机构的ca0，org2中的证书颁发机构的ca1

Answer 2

尝试在

中替换peer0.org1.example.com，peer0.org1.example.com，ca.org1.example.com和orderer.example.com

sed -e 's/localhost:7051/peer0.org1.example.com:7051/' \
    -e 's/localhost:7053/peer0.org1.example.com:7053/' \
    -e 's/localhost:7054/ca.org1.example.com:7054/' \
    -e 's/localhost:7050/orderer.example.com:7050/' \
    < $HOME/.composer/cards/restadmin@trade-network/connection.json \
    > /tmp/connection.json && \
    cp -p /tmp/connection.json $HOME/.composer/cards/restadmin@trade-network/

使用IP地址的

命令，如：

sed -e 's/localhost:7051/192.168.0.170:7051/' \
    -e 's/localhost:7053/192.168.0.170:7053/' \
    -e 's/localhost:7054/192.168.0.170:7054/' \
    -e 's/localhost:7050/192.168.0.170:7050/' \
    < $HOME/.composer/cards/restadmin@trade-network/connection.json \
    > /tmp/connection.json && \
    cp -p /tmp/connection.json $HOME/.composer/cards/restadmin@trade-network/

Hyperledger composer rest server：尝试ping时出错。错误：没有可用于查询的对等项。最后一个错误是错误：14 UNAVAILABLE：连接失败
