hyperledger fabric 发现服务背书失败

Question

大家好，我正在尝试将服务发现与节点 js 客户端结合使用来生成交易提案，我遇到的问题是，当发现生成背书计划时，它会将提案发送给同一对等点，但背书失败，这是生成的背书计划之一，idk 为什么但是对等名称都是错误的

Answer 1

我们能看到通道初始化时的调试日志吗？查看从 Peer 的 Discovery Service 中读取的 Discovery 结果会很有帮助。背书计划中看到的 Peer 的名称不是来自 Discovery Service，这是 NodeSDK 分配的名称，这些名称应该是唯一的并且包含主机和端口。由于它们不是唯一的，因此确实使用了同一个 Peer。

Answer 2

当 NodeSDK 应用程序是运行第一级并且在本地虚拟环境中使用 fabric 网络时，对等地址被视为 "localhost"，虚拟环境中的端口地址必须也是独一无二的。在 docker-compose 将虚拟端口映射到真实端口时，使用相同的地址是最简单的。请注意，在以下示例中，定义虚拟环境的端口地址与主机映射相同。

    environment:
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - CORE_PEER_ID=peer0.org2.example.com
      - CORE_PEER_ADDRESS=peer0.org2.example.com:8051
      - CORE_PEER_LISTENADDRESS=peer0.org2.example.com:8051
      - CORE_PEER_GOSSIP_ENDPOINT=peer0.org2.example.com:8051
      - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org2.example.com:8051
      - CORE_PEER_LOCALMSPID=Org2MSP
      - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/peerOrg2/msp
      - CORE_PEER_GOSSIP_BOOTSTRAP=peer0.org2.example.com:8051

    ports:
      - 8051:8051

请记住，主机名也必须从虚拟名称映射到 "localhost"，这是通过在初始化通道时使用连接选项 "aslocalhost:true" 完成的。

await channel.initialize({discover:true, asLocalhost:true})
