mod_rewrite urlencoding 一个已经 urlencoded 的查询字符串参数 - 有什么方法可以禁用它吗? [英] mod_rewrite urlencoding an already urlencoded query string parameter - any way to disable this?
问题描述
我们有一些非常基本的 mod_rewrite 规则:
We have some very basic mod_rewrite rules:
RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,L]
mod_rewrite 似乎完成了它的工作，如果用户正在访问:
mod_rewrite seems to do its job, and if the user is accessing:
something.swf?param=value，正确重定向到 http://www.newdomain.com/something.swf?param=value
问题出在这种情况下:
www.olddomain.com/something.swf?param=URL_ENCODED_VALUE
最终发生的是 mod_rewrite 自行重新对查询字符串参数进行 urlencode
what ends up happening is mod_rewrite takes it upon it self to re-urlencode the query string param
所以用户最终得到的是:
so what the user ends up with is:
www.olddomain.com/something.swf?param=URL_ENCODED_VALUE
重定向到
www.newdomain.com/something.swf?param=URL_ENCODED_VALUE_OF_URL_ENCODED_VALUE
所以我们最终得到一个双 urlencoded 值.赞！
so we end up with a double-urlencoded value. boourns!
虽然我明白我们可以为此制定一个 \?(.*) ... ?$1 规则，但我认为必须有一种方法可以告诉mod_rewrite 不是对查询字符串参数进行 urlencode...我们希望避免使用 2 条规则，因为有效路径是:
While I do understand we could make a \?(.*) ... ?$1 rule for this, I am thinking there must be a way to tell mod_rewrite NOT to urlencode the query string params... we would like to avoid using 2 rules since valid paths are:
something.swf (no query string)
和
something.swf?someparams...
是的，理想情况下...只需告诉 mod_rewrite:请不要对查询字符串参数进行 urlencoding...只需通过 R=302 直接传递到新 URL.
so yea, ideally... just tell mod_rewrite: please, no urlencoding of query string params... just direct passthru to the new URL via R=302.
推荐答案
实现这一点的方法是通过 NE(无转义)参数.
the way to accomplish this is via the NE (no escape) paramater.
RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,L]
其实应该读
RewriteRule ^something.swf$ http://www.newdomain.com/something.swf [R=302,NE,L]
这将强制 mod_rewrite 保留所有查询字符串值原样，而不进行任何编码/转义.
this will force mod_rewrite to leave all query string values as they are, without doing any encoding / escaping.
就这么简单:)
