是否有最大HTTP状态代码消息长度？ [英] Is there a maximum HTTP status code message length?

问题描述

我正在开发一个项目，我正在构建前端，而其他人正在构建API。我为所有请求提出了以下结构，以JSON格式发送：

I'm working on a project where I'm building the frontend and someone else is building an API. I was proposing the following structure for all requests, sent as JSON:

{
  "success": true, // true/false
  "message": null, // a string if success==false indicating the error
  "data": {} // The actual data in the response
}

他们更感兴趣的是让API更加RESTful，而不是他们提出的消息字段在HTTP标头中的状态代码消息中发回消息，例如：

They are more interested in making the API more RESTful, and instead of a "message" field they are proposing sending a message back in the status code message, in the HTTP headers, such as:

HTTP/1.1 401 Authentication Failed for [e-mail]. Please log in again.

并且前端会显示[e-mail]的身份验证失败。请再次登录。在弹出窗口或其他东西。

and the frontend would display "Authentication Failed for [e-mail]. Please log in again." in a popup or something.

我担心长度限制，但我找不到任何表示没有最大长度的东西。我们应该确保将这些消息保持在最小长度吗？有没有充分的理由不这样做，而是将其作为内容（JSON或纯文本）发回？

I'm worried about length restrictions, but I couldn't find anything indicating no maximum length. Should we ensure we keep those messages to a minimum length? Is there a good reason to not do this, and instead send it back as content (JSON or plain text)?

推荐答案

A很少进行测试会有很长的路要走，但你应该可以做到这一点，事实上 RFC 具体说明：

A little testing will go a long way, but you should be okay to do this and in fact the RFC says specifically:

此处列出的原因短语只是建议 - 它们可能被替换为本地等价物而不影响协议。

The reason phrases listed here are only recommendations -- they MAY be replaced by local equivalents without affecting the protocol.

唯一可能的问题是标题大小（某些服务器可能有限制，但我认为它们都相对较大）以及一些旧的浏览器可能会对此作出反应。坦率地说，我认为使用响应体更有意义，因为它更容易解释和清除，但是你的方法应该没有任何问题。

The only possible concern you may have is header size (some servers may have limitations, but I think they are all relatively large) and how some older browsers may react to this. Frankly I think it makes more sense to use the response body since it's easier to interpret and clear, but there shouldn't be anything wrong with your approach.
