✨ [Feature] 规范 HTTP 状态码返回

[devhaozi]

在提问之前 (Before Asking)

• 我已经搜索了全部 Issues 和 Commits (I have searched all Issues and Commits)
• 它们当中没有我将要提交的新功能 (None of them have new feature that I'm going to submit)

描述功能 (Describe Feature)

当前基本都是返回 200，然后里面套了个 code，为了规范应该把 code 去掉直接以状态码表示。

工作流程 (WorkFlow)

待定

还有别的吗 (Anything Else)
