正则表达式URL匹配除www以外的任何内容 [英] Regex URL match on anything but www

问题描述

我正在使用IIS7和URL重写模块.

I'm using IIS7 and the URL Rewrite module.

我想使用正则表达式来匹配www以外的任何子域.

I would like to use regex to match any subdomain apart from www.

所以...

frog.domain.co.uk = Match
m.domain.co.uk = Match
anything.domain.co.uk = Match
www.domain.co.uk = No match

通过这种方式，我可以将有人输入的任何子域重定向回www.

This way I can redirect any subdomain that someone types in back to www.

推荐答案

使用此规则-如果域不同，它将重定向到www.exmaple.com域:

Use this rule -- it will redirect to www.exmaple.com domain if domain is different:

<system.webServer>
      <rewrite>
          <rules>
              <rule name="Force www" stopProcessing="true">
                  <match url="(.*)$" />
                  <conditions>
                      <add input="{HTTP_HOST}" pattern="^www\.example\.com" negate="true" />
                  </conditions>
                  <action type="Redirect" url="http://www.example.com/{R:1}" />
              </rule>
          </rules>
      </rewrite>
  </system.webServer>

如果您不想两次输入域名(example.com)，则可以对其进行一些优化-但这是非常小的事情，根据您的情况/配置，这可能是不希望的.

You can optimize it a bit if you do not want to type domain name twice (example.com) -- but that is very minor thing and depending on your circumstances/configuration it is can be undesired.
