gRPC 套接字关闭消息

Question

我用 Go 开发了一个 gRPC 服务器，用 Python 开发了一个客户端，当服务器中的服务器任务耗时太长时，客户端出现以下错误，服务器运行时没有任何错误。

 raise _Rendezvous(state, None, None, deadline)
grpc._channel._Rendezvous: <_Rendezvous of RPC that terminated with:
    status = StatusCode.UNAVAILABLE
    details = "Socket closed"
    debug_error_string = "{"created":"@1573373169.327520081","description":"Error received from peer","file":"src/core/lib/surface/call.cc","file_line":1039,"grpc_message":"Socket closed","grpc_status":14}"

像这样增加超时不起作用，在超时之前，大约 4 秒，我得到了错误。

res = stub.Fake(
    fake_pb2.FakeRequest(
        **fake_request
    ),
    timeout=9
)

grpc状态码14不可用多为暂时性错误，可通过重试机制纠正。
