即使在使用urlencode，URL中的&符之后的数据也会被剥离 [英] data being stripped off after ampersand in URL even when using urlencode

问题描述

我在要获取请求的URL中传递与号

I am passing ampersands in a URL which go into a get request

例如

http://www.soundshelter.co.uk/label/Hit & Run

我尝试对&以便它是有效的URL

I have tried to urlencode the & so that it is a valid URL

http://www.soundshelter.co.uk/label/Hit%20%26%20Run

，但是在get请求中URL的& Run部分已被截断.

but the & Run section of the URL is being cut off in the get request.

我认为这可能与我的mod_rewrite有关

I'm thinking this might have something to do with my mod_rewrite

RewriteRule ^label/([^/]*)$ /index.php?label=$1 [NC]

获取请求是

$label = $_GET['label'];

有什么想法吗?

欢呼

推荐答案

来自 the文档:

'B'(转义反向引用)

'B' (escape backreferences)

Apache必须先对URL进行转义，然后再对它们进行映射，因此反向引用将 在他们被解脱的时候 应用.使用B标志， 中的非字母数字字符 向后引用将被转义.为了 例如，请考虑以下规则:

Apache has to unescape URLs before mapping them, so backreferences will be unescaped at the time they are applied. Using the B flag, non-alphanumeric characters in backreferences will be escaped. For example, consider the rule:

 RewriteRule ^(.*)$ index.php?show=$1 

这会将/C++映射到index.php?show=/C++.但这也会 将/C%2b%2b映射到index.php?show=/C++， 因为%2b已被转义. 使用B标志，它将改为映射 到index.php?show=/C%2b%2b.

This will map /C++ to index.php?show=/C++. But it will also map /C%2b%2b to index.php?show=/C++, because the %2b has been unescaped. With the B flag, it will instead map to index.php?show=/C%2b%2b.

在代理情况下，当 如果提供的话，后端可能会折断 带有未转义的URL.

This escaping is particularly necessary in a proxy situation, when the backend may break if presented with an unescaped URL.

因此，尝试:

RewriteRule ^label/([^/]*)$ /index.php?label=$1 [BNC]
