使用路径前缀规则时如何使用 Traefik 重写路径? [英] How to rewrite paths with Traefik when using path prefix rules?

问题描述

我的 WordPress 的 Traefik 配置包含以下 docker-labels:

My Traefik config for WordPress contains the following docker-labels:

- "traefik.backend=wordpress"
- "traefik.docker.network=web"
- "traefik.frontend.rule=Host:MyHostName.net;PathPrefix:/blog"
- "traefik.enable=true"
- "traefik.port=80"

现在请求网址https://MyHostName/blog"；似乎到达了似乎返回重定向到https://MyHostName/wp-admin..."的服务.

Now requesting the url "https://MyHostName/blog" seems to reach the service which seems to return a redirect to "https://MyHostName/wp-admin...".

我不能使用子域.

我该如何解决这个问题?

How can I solve this?

首先应该添加过滤器PathPrefixStrip:/blog"；删除/blog"将请求转发到服务时的前缀.正确吗?

First thing to do should be adding the Filter "PathPrefixStrip:/blog" to remove the "/blog" prefix when forwarding the request to the service. Correct?

但是我如何修改(例如)重定向请求以添加前缀/blog"?到重定向网址?

But how do I modify (for example) a redirect request to add the prefix "/blog" to the redirect URL?

在 https://github.com/containous/traefik/issues/985 我的问题是讨论过的"；并且似乎合并了一个解决方案(https://github.com/containous/traefik/pull/1442).

At https://github.com/containous/traefik/issues/985 my question is "discussed" and a solution seems to be merged (https://github.com/containous/traefik/pull/1442).

简而言之:剥离的前缀将被添加为相应的标头(X-Forwarded-Prefix).

In short: Stripped prefixes will be added as the respective header (X-Forwarded-Prefix).

我会检查并在此处写下结果.

I will check that and write down the results here.

现在我创建了一个如下所示的请求:

Now I created a request looking like this:

https://MYHOSTNAME/blog

PathPrefixStrip"似乎朝着 CLIENT>>SERVICE 的方向工作.这是我的 traefik 日志包含的内容:

The "PathPrefixStrip" seems to work in the direction CLIENT>>SERVICE. This is what my traefik log contains:

      ],
      "Upgrade-Insecure-Requests":[
         "1"
      ],
      "User-Agent":[

      "X-Forwarded-Prefix":[
         "/blog"
      ]
   },
   "ContentLength":0,
   "TransferEncoding":null,
   "Host":"MYHOSTNAME",

   "Trailer":null,
   "RemoteAddr":"81.128.35.176:33468",
   "RequestURI":"/",
   "TLS":null
}
"

但重定向答案在我的浏览器中如下所示:

But the redirection answer looks as follows in my browser:

HTTP/2.0 302 Found
cache-control: no-cache, must-revalidate, max-age=0
content-length: 0
content-type: text/html; charset=UTF-8
date: Wed, 04 Apr 2018 18:44:18 GMT
expires: Wed, 11 Jan 1984 05:00:00 GMT
location: https://MYHOSTNAME/wp-admin/install.php
server: Apache/2.4.25 (Debian)
X-Firefox-Spdy: h2
x-powered-by: PHP/7.2.2

因此重定向响应不包含任何有关剥离路径前缀/blog"的信息.

So the redirect-response does not contain any information about the stripped path prefix "/blog".

最后看起来是容器内服务的软件不处理标头的问题.

At the end it looks like a problem of the served software inside the container that does not handle the header.

有什么想法吗?

推荐答案

也许您应该在 PathPrefixStrip:/blog 规则中添加所有可能的值，例如.

Maybe you should add all possible values in your PathPrefixStrip: / blog rule eg.

PathPrefixStrip: /blog,/wp-admin,/abc,/xyz

在许多情况下，它适用于标准路线.最大的问题是当您的后端服务不侦听根目录 / 中的请求，而是在某些子目录 /something/index.html 中并且该子目录占用资源时从根 / 开始.

In many cases, it works for standard routes. The biggest problem is when your backend service does not listen to requests in the root / but in some sub-dir /something/index.html and that sub-dir takes resources from the root /.
