使用fabric-sdk-go安装chaincode时的连接超时 [英] Connection timeout when installing chaincode using fabric-sdk-go
问题描述
我有一个问题，当使用fabric-sdk-go安装链码时，总是会有grpcs超时. GRCPS请求是从本地计算机向其docker容器发出的.
I have a problem that there is always a grpcs timeout when installing the chaincode using fabric-sdk-go. The GRCPS request is made from the local machine to its docker containers.
ErrorMsg:
lscc.getinstalledchaincodes失败:SendProposal失败:背书人[localhost:7051]的事务处理:背书人客户端状态代码:(2)CONNECTION_FAILED.说明:拨号连接超时[localhost:7051]
lscc.getinstalledchaincodes failed: SendProposal failed: Transaction processing for endorser [localhost:7051]: Endorser Client Status Code: (2) CONNECTION_FAILED. Description: dialing connection timed out [localhost:7051]

我的network-config.yaml有什么问题吗?
Is there anything wrong with my network-config.yaml???
我尝试过的事情:
-
试图在docker-compose.yaml中禁用CORE_PEER_TLS_CLIENTAUTHREQUIRED，失败..
Tried to disable CORE_PEER_TLS_CLIENTAUTHREQUIRED in docker-compose.yaml, failed..
编辑的/etc/hosts文件，其行为127.0.0.1 peer1-xiaoyudian ...，失败..
Edited /etc/hosts file with the line 127.0.0.1 peer1-xiaoyudian..., failed..
增加network-config.yaml中的peer.timeout.connections和其他超时选项，失败..

增加network-config.yaml中的grpcOptions.keep-alive-time，失败..

答案: 火箭上的某人告诉我:
Answer: Someone from the rocket.chat told me:
- 运行:导出GRPC_GO_LOG_SEVERITY_LEVEL =错误
- 运行:导出GRPC_GO_LOG_VERBOSITY_LEVEL = 2
- 在客户端代码中添加以下行: grpclog.SetLogger(logger)
- run: export GRPC_GO_LOG_SEVERITY_LEVEL=error
- run: export GRPC_GO_LOG_VERBOSITY_LEVEL=2
- in the client code add this line: grpclog.SetLogger(logger)
日志显示这是一个与同级握手的证书问题.
And the log says it a certificate issue for handshaking with peers.
推荐答案
Refer https://github.com/hyperledger/fabric-sdk-go/tree/master/test/fixtures/config/overrides
for how URLs are overridden to use localhost. In your case, you have to use local_entity_matchers.yaml & local_orderers_peers_ca.yaml combined in samples provided.
我在您的network-config.yaml中注意到的另一件事，映射的主机名与实际的对等名称相同.实体匹配器不在这里加入.请参考上面示例中使用的实体匹配器.
One more thing I noticed in your network-config.yaml, mapped host name is same as actual peer name. Entity matcher doesn't kick in here. Refer the entity matchers used in the sample given above.
