About the problem of standardizing routing request parameters

[wln32]

1. What version of Go and system type/arch are you using?

go 1.19.3, windows/amd64

2. What version of GoFrame are you using?

GoFrame CLI Tool v2.5.1, https://goframe.org

3. Can this issue be re-produced with the latest release?

可以

4. What did you do?

当规范路由req参数不是指针的时候，注册的时候不会报错，但是运行时会报错
exception recovered: reflect: Elem of invalid type ghttp_test.TestForHandlerWithObjectAndMeta1Req

5. What did you expect to see?

是否可以在注册的时候提示必须为指针？

6. What did you see instead?

当规范路由req参数不是指针的时候，注册的时候不会报错，但是运行时会报错
exception recovered: reflect: Elem of invalid type ghttp_test.TestForHandlerWithObjectAndMeta1Req

type TestReq struct {
		Age  int
		Name string
	}
type TestRes struct {
	Id   int
	Age  int
	Name string
}
s := g.Server(guid.S())

// 注意这里的req参数是值类型，注册的时候没有报错，调用时候会报错
s.BindHandler("/test", func(ctx context.Context, req TestReq) (res *TestRes, err error) {
	return &TestRes{
		Id:   1,
		Age:  req.Age,
		Name: req.Name,
	}, nil
})
s.BindHandler("/test/error", func(ctx context.Context, req *TestReq) (res *TestRes, err error) {
	return &TestRes{
		Id:   1,
		Age:  req.Age,
		Name: req.Name,
	}, gerror.New("error")
})
s.SetDumpRouterMap(false)
s.Start()

// gf\net\ghttp\ghttp_request_middleware.go：（*middleware).callHandlerFunc
// 原因是这里
if funcInfo.Type.In(1).Kind() == reflect.Ptr {
	inputObject = reflect.New(funcInfo.Type.In(1).Elem())
	m.request.error = m.request.Parse(inputObject.Interface())
} else {
       // 不是指针类型但还是使用elem方法导致报错，非指针类型调用elem会导致panic
	inputObject = reflect.New(funcInfo.Type.In(1).Elem()).Elem()
	m.request.error = m.request.Parse(inputObject.Addr().Interface())
}
