<!-- Please use this template while reporting a bug and provide as much info as possible. Not doing so may result in your bug not being addressed in a timely manner. Thanks! --> **What happened**: 基于当前的 [JSON-RPC](https://github.com/apache/dubbo-go-samples/tree/master/rpc/jsonrpc) 示例，**将调用接口方法入参与出参都改造为 `struct` 后**，Server 端抛出异常，方法无法正常执行。 Client 改造后方法 ``` logger.Infof("\n\n\nstart to test jsonrpc") user := &pkg.JsonRPCUser{ ID: "A003", } user, err := userProvider.GetUser(context.TODO(), user) if err != nil { panic(err) } logger.Infof("response result: %v", user) ``` Server 改造后方法 ``` func (u *UserProvider) GetUser(ctx context.Context, userID *User) (*User, error) { var ( err error user *User ) gxlog.CInfo("userID:%#v", userID) user, err = u.getUser(userID.ID) if err == nil { gxlog.CInfo("rsp:%#v", user) } return user, err } ``` Client 异常日志 ``` start to test jsonrpc 2021-11-11T14:53:49.338+0800 WARN proxy/proxy.go:215 result err:

reproduce it (as minimally and precisely as possible)**: - **Anything else we need to know?**: 可能原因：Dubbo-go 服务代理执行时，参数类型没有得到正确解析。 -- This is an automated message from the Apache Git Service.
