根因分析

客户端调用了服务器尚未注册的 gRPC 服务。服务器可能未正确编译 .proto 文件,或缺少服务注册。

English

Client is calling a gRPC service that the server has not registered. The server may not have the correct .proto compiled, or the service registration is missing.

解决方案

  1. 95% 成功率
    In server main: pb.RegisterGreeterServer(s, &server{})
  2. 90% 成功率
    protoc --go_out=. --go-grpc_out=. helloworld.proto

无效尝试

常见但无效的做法:

  1. 80% 失败

    The server binary still contains old generated code, so the service is still unavailable.

  2. 90% 失败

    This will only produce a different Unimplemented error, not fix the root cause.
