什么是 X-REQUEST-ID http 标头? [英] What is the X-REQUEST-ID http header?

问题描述

我已经在这个主题上搜索了很多，阅读了关于这个标题的各种文章，它在 Heroku 中的使用，以及基于 Django 的项目.

I have already googled a lot this subject, read various articles about this header, its use in Heroku, and projects based on Django.

然而，我的脑子里还是一片混乱.

However, it's still all confused in my head.

• 此标头的用途是什么?
• 是否侵犯用户隐私?
• 它可以帮助跟踪用户吗?

推荐答案

当您操作一个客户端访问的 Web 服务时，可能很难将请求(客户端可以看到)与服务器日志(客户端可以看到)关联起来.服务器可以看到).

When you're operating a webservice that is accessed by clients, it might be difficult to correlate requests (that a client can see) with server logs (that the server can see).

X-Request-ID 的想法是客户端可以创建一些随机 ID 并将其传递给服务器.然后，服务器在它创建的每个日志语句中都包含该 ID.如果客户端收到错误，它可以将 ID 包含在错误报告中，从而允许服务器操作员查找相应的日志语句(无需依赖时间戳、IP 等).

The idea of the X-Request-ID is that a client can create some random ID and pass it to the server. The server then include that ID in every log statement that it creates. If a client receives an error it can include the ID in a bug report, allowing the server operator to look up the corresponding log statements (without having to rely on timestamps, IPs, etc).

由于此 ID 由客户端(随机)生成，它不包含任何敏感信息，因此不应侵犯用户的隐私.由于每个请求都会创建一个唯一 ID，因此它也无助于跟踪用户.

As this ID is generated (randomly) by the client it does not contain any sensitive information, and should thus not violate the user's privacy. As a unique ID is created per request it does also not help with tracking users.
