根因分析

服务端已注册该服务但未注册此特定方法。通常由过时的生成服务端 stub，或客户端使用比服务端更新的 proto 引起。

English

The server has registered the service but not this specific method. Typically caused by an outdated generated server stub or a client using a newer proto than the server.

解决方案

  1. 95% 成功率 
    protoc --go_out=. --go-grpc_out=. user.proto
go build ./...
  2. 90% 成功率 
    grpcurl -plaintext localhost:50051 describe pb.UserService

无效尝试

常见但无效的做法:

  1. 90% 失败

    The method handler must exist as a generated function; string manipulation on descriptors does not register a callable handler

  2. 70% 失败

    The older method may not exist either; the correct fix is aligning proto versions
