将子域作为参数传递 [英] Pass subdomain as parameter

问题描述

我是ISAPI_Rewrite&的新手.我很讨厌正则表达式.我需要 ISAPI_Rewrite 的重写规则，该规则将删除子域并将其作为参数传递.例如:

I'm new to ISAPI_Rewrite & I'm terrible with regular expressions. I'm in need of a rewrite rule for ISAPI_Rewrite that will remove the subdomain and pass it as a parameter. For example:

mysubdomain.mydomain.com

应该成为

mydomain.com/Landing.aspx?ID=mysubdomain

我已经找到了一个 正则表达式，该正则表达式似乎与除www之外的所有子域都匹配，但是我不确定如何将子域作为参数传递，如上面的示例所示.

I've found a regex that seems to match all subdomains except www, but I'm not sure how to then pass the subdomain as a parameter as the example above shows.

^((?:(?!www).)*)

任何帮助将不胜感激.

注意::我使用的是ISAPI_Rewrite的完整版，因此此规则将在网站级别执行.

Note: I'm using the full version of ISAPI_Rewrite so this rule will be at the site-level.

全局规则:

# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.89

#Disable extentionless processing for ASP.Net v 4.0
RewriteRule (.*)eurl.axd/.* $1

# Don't rewrite urls that are inside the assets folder or have the following extentions
RewriteRule ((^/Assets/.*)|(.*\.axd.*)|(.*\.asmx.*)|(.*\.png.*)) $1 [NC,L]

#Rewrite URL, pass last portion of URL to Landing.aspx + purl
RewriteRule  (.*) $2/landing.aspx\?id=$1 [NC]

推荐答案

类似的方法可能对您有用:

Something like this may work for you:

# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

RewriteCond %{QUERY_STRING} ^$
RewriteCond %{HTTP_HOST} ([^.]+)(?<!^www)(\.|$) [NC]
RewriteRule ^ Landing.aspx?ID=%1 [L,QSA]

PS:您的全局规则似乎与我的上述规则相冲突.因此，我建议您使用这样的全局规则来避免冲突:

PS: Looks like your global rule is in conflict with above rule of mine. I would therefore suggest you to have your global rule like this to avoid conflict:

RewriteCond %{QUERY_STRING} ^$
RewriteCond %{HTTP_HOST} !mydomain\.com$ [NC]
RewriteRule ^(.*)$ landing.aspx?id=$1 [L]
