Question

我目前正在为我正在研究的Hyperledger Composer项目建立自定义Hyperledger Fabric网络。

Composer文件已经可以使用提供的现成的dev结构服务器（即./startFabric.sh）完美运行。我已经按照tutorial的方法，使用给定的byfn.sh将现有业务网络部署到多组织情况，并且网络已成功安装（composer network install ...已成功安装{{ 1}}在光纤网络上。

现在，我尝试修改.bna以支持3（三个）组织，每个组织只有一个同级。其他文件（crypto-config.yaml，configtx.yaml，scripts/script.sh和docker compose文件）也进行了相应的修改。

byfn.sh中的e2e测试实际上已经成功运行（直到出现“ END” ASCII码），这使我认为结构网络已成功建立。 script/script.sh命令也shows表示Docker容器正在运行。

但是，当我尝试在安装结构上执行docker ps时，它会输出以下内容：

composer network install

即使端到端测试运行正常，为什么也会出现此错误？我怀疑connection.json file的配置不正确，因为e2e运行得很好（（ “ $ composer network install -c PeerAdmin@example-org1 -a stockchainz.bna ✖ Installing business network. This may take a minute... Error: Error trying install business network. Error: No valid responses from any peers. Response from attempted peer comms was an error: Error: Failed to connect before the deadline Command failed”和“ INSERT_..._CA_CERT”已替换为正确的值）

浏览日志后，我发现grpc找不到对等方。原来这是一个证书问题，我的怀疑是正确的。设置GRPC_VERBOSITY=DEBUG会在重新执行composer network install时显示日志：

...
D0507 12:21:21.934229064   14853 security_handshaker.cc:127] Security handshake failed: {"created":"@1557231681.934207000","description":"Peer name localhost is not in peer certificate","file":"../deps/grpc/src/core/lib/security/security_connector/security_connector.cc","file_line":780}
...

connection.json将所有对等方的URL设置为grpcs://localhost:<port>。而不是这样：

...
"peer0.org1.example.com": {
    "url": "grpcs://localhost:7051",
    "tlsCACerts" : {
        "pem": "INSERT_ORG1_CA_CERT"
    }
},
...

我将其更改为此：

...
"peer0.org1.example.com": {
    "url": "grpcs://localhost:7051",
    "grpcOptions": {
        "ssl-target-name-override": "peer0.org1.example.com"
     },
    "tlsCACerts" : {
        "pem": "INSERT_ORG1_CA_CERT"
    }
},
...

这样做之后，业务网络归档文件已成功安装：
