根因分析

服务器未实现请求的 RPC 方法，可能是由于 proto 生成过时。

English

The server does not implement the requested RPC method, possibly due to outdated proto generation.

解决方案

  1. 95% 成功率 
    protoc --go_out=. --go-grpc_out=. *.proto; go build -o server server.go
  2. 90% 成功率 
    if err := pb.RegisterGreeterServer(s, &server{}); err != nil { log.Fatal(err) }
  3. 85% 成功率 
    Ensure method name matches exactly: client.SayHello(ctx, req)

无效尝试

常见但无效的做法:

  1. Trying other methods that also don't exist. 80% 失败

    All methods may be unimplemented.

  2. Using nil response from failed call. 90% 失败

    Nil pointer dereference.

  3. Assuming the method was removed. 60% 失败

    May still be needed.
