零值字段在响应的时候为空

[qingyggg]

Describe the Question 1.以下是我定义的接口类型： { "article": { 。。。。 "info": { "comment_count": 0, "dislike_count": 0, "is_favorite": true, "like_count": 0, "viewed_count": 0 } }, "status_code": 0, 。。。 } 以下是实际的返回值： { "status_code": 0, "article": { "info": { "viewed_count": 2 }, } } Reproducible Code

Please construct a minimum complete and reproducible example for us to get the same error. And tell us how to reproduce it like how you send a request or send what request.

Expected behavior 我希望hertz在处理接口的时候，响应所有的字段，及时是某些字段是go语言的零值，我也希望它有一个结果(0,"",nil),这样子我好在前端做处理，所以，我应该怎么设置才能达到预期的效果 Screenshots

可以查一下 json marshal 的行为，hertz 返回调用的 json.marshal 接口进行序列化
