Traefik 重定向

Question

我正在尝试在 Traefik 的文件提供程序中实现基本重定向。我会 如下所示：

http://example.com/foobar      ->  https://foobar.example.com
http://www.example.com/foobar  ->  https://foobar.example.com
https://example.com/foobar     ->  https://foobar.example.com
https://www.example.com/foobar ->  https://foobar.example.com

这是我的尝试：

http:
  middlewares:
    redirect-foobar:
      redirectRegex:
        permanent: true
        regex: "^https?://(www\\.)?example\\.com/foobar(/?.*)"
        replacement: "https://foobar.example.com${2}"
  routers:
    catch-foobar:
      middlewares:
        - redirect-foobar
      rule: Host(`example.com`) || Host(`www.example.com`)
      service: noop@internal

但是当我尝试时，我得到的是：

$ curl -I http://www.example.com/foobar 
HTTP/1.1 308 Permanent Redirect
Location: https://foobar.example.com
Date: Wed, 02 Mar 2022 02:12:48 GMT
Content-Length: 18
Content-Type: text/plain; charset=utf-8

# That's good =)

$ curl -I https://www.example.com/foobar
HTTP/2 404 
content-type: text/plain; charset=utf-8
x-content-type-options: nosniff
content-length: 19
date: Wed, 02 Mar 2022 02:05:22 GMT

# Does that mean the request didn't even make it to the catch-foobar router?

我做错了什么？任何帮助将不胜感激。

谢谢，

C

编辑：修复了正则表达式，但 https 情况仍然有问题

Traefik 社区论坛的人们帮助了我。原来是路由器没有tls配置。正确的配置如下所示：

http:
  middlewares:
    redirect-foobar:
      redirectRegex:
        permanent: true
        regex: "^https?://(www\\.)?example\\.com/foobar(/?.*)"
        replacement: "https://foobar.example.com${2}"
  routers:
    catch-foobar:
      middlewares:
        - redirect-foobar
      rule: Host(`example.com`) || Host(`www.example.com`)
      service: noop@internal
      tls:  # here
        certResolver: default

其中 default 是我的 traefik.yml 中定义的证书解析器。
