“万维网"到“非 WWW"使用 Traefik 的请求变量重定向? [英] "WWW" to "Non-WWW" redirect using request variables with Traefik?

问题描述

对于我对 Traefik 的新手理解，我提前道歉，但是有没有办法使用基于请求的变量重写非 www"域?

I apologize in advance for my novice understanding with Traefik, but is there a way to rewrite to "non-www" domains with a request-based variable?

我已经在谷歌上搜索了一个多小时，但找不到答案.

I've been Googling for over an hour and cannot find an answer.

这是我如何在 Apache 中执行此操作的示例.您可以看到它正在使用 HTTP_HOST 变量:

Here is an example how I would do this in Apache. You can see it is using the HTTP_HOST variable:

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

我可以看到我可以像这样设置标签:

I can see that I can set labels like so:

--label "traefik.frontend.redirect.permanent=true" 
--label "traefik.frontend.redirect.regex=^https?://www.example.com/(.*)"
--label "traefik.frontend.redirect.replacement=https://example.com/${1}"

但这需要我为所有内容设置 example.com.我希望无论域如何都可以重定向.谢谢！

But this requires me to set example.com for everything. I would like this to redirect regardless of the domain. Thanks!

推荐答案

我在 Traefik Slack 小组中找到了一些帮助，并且一位用户为我指明了正确的方向.使用他们的文档(https://docs.traefik.io/configuration/entrypoints/#rewriting-url)，他能够帮我写正则表达式来解决我的需求:

I found some help in the Traefik Slack group and a user pointed me in the right direction. Using their documentation (https://docs.traefik.io/configuration/entrypoints/#rewriting-url), he was able to help me write regular expressions that solved my need:

[entryPoints.https.redirect]
permanent=true
regex = "^https://www.(.*)"
replacement = "https://$1"
