国防部重写删除www和转％2520送入太空

问题描述

WWW重定向到非工作正常，但转弯％2520所有出现的空间，使用QUERY_STRING看来，当我将它们合并失败。
我一派，并结合的RewriteCond和重写规则的SOed负载，但我无法找到一个例子，即使似乎接近这一个是如何工作的。所有我已经计算出的是，我可能滥用（。*）正则表达式。总的正则表达式并在这里mod_rewrite的小白 - ！没有冷嘲热讽，请:-)在此先感谢

我已经试过这一点，相反的：

 的RewriteCond％（HTTP_HOST）^ www.mywebsite \\ .COM $
重写规则（。*）http://mywebsite.com/$1 [R = 301，L]
的RewriteCond％{QUERY_STRING} ^（。*）（2520％）（。*）$
重写规则^（。+）$ $ 1？％1 \\％3 [N，R = 301]
 

解决方案

这是网址都有它允许有限的字符集。不允许有空格为在URL中的字符，因此它们都带coded到 20％。类似地，％2520 是一个双连接codeD空间。

您为我优秀作品规则（你可以离开了周围的捕获组％2520 ，因为它是不必要的，但它不会破坏任何东西）。这将改变 http://example.com/minimalonecharacter?asdf%2520qwer 到 http://example.com/minimalonecharacter?asdf%20qwer 。

我注意到，您使用的状态code 301 （永久重定向）这一点。我推荐的不的具有永久重定向测试，直到一切都按你想要的工作。浏览器可能会缓存永久重定向，跳绳对服务器的请求。如果你作出错误的重写规则，这样的结果是缓存和未来的尝试奇怪的角度去你的第一次尝试。

Redirecting www to non is working fine, but turning all occurrences of %2520 to a space, using QUERY_STRING seems to fail when I combine them.I've Googled and SOed loads of combining RewriteCond and RewriteRule but I can't find an example that even seems close to how this one works. All I've worked out is that I'm probably abusing the (.*) regex. Total regex and mod_rewrite noob here - no snide comments please :-) Thanks in advance!

I've tried this, and the reverse:

RewriteCond %(HTTP_HOST) ^www.mywebsite\.com$
RewriteRule (.*) http://mywebsite.com/$1 [R=301,L]
RewriteCond %{QUERY_STRING} ^(.*)(%2520)(.*)$
RewriteRule ^(.+)$ $1?%1\ %3 [N,R=301]

解决方案

An url has a limited subset of characters it allows. Spaces are not allowed as a character in an url, and therefore they are encoded to %20. Similary, %2520 is a double encoded space.

The rule you provide works fine for me (you could leave out the capturing group around %2520 as it is unnecessary, but it doesn't break anything). It will transform http://example.com/minimalonecharacter?asdf%2520qwer to http://example.com/minimalonecharacter?asdf%20qwer.

I notice that you use status code 301 (permanent redirect) for this. I recommend not testing with a permanent redirect, until everything works as you want it to work. The browser might cache a permanent redirect, skipping a request to the server. If you make a wrong rewriterule, this result is cached and future attempts "strangely" point to your first attempt.
