转义符号在$ _GET htaccess的重写规则失败 [英] htaccess rewrite rule with escaped ampersand in $_GET fails

问题描述

我遇到了在与htaccess的重写规则一起GET参数有问题。 下面是urlen code（）'版的链接;我用的是重写规则重定向到的index.php，最后，在index.php一的print_r（$ _ GET）。 正如你所看到的，urlescaped符号不是静态变量值的一部分，而是和出乎我的期望得到除preTED为变量分隔符。 为什么？

初​​始链接：

 ＆LT; A HREF =静态/游戏，技％26艺术实验室＆GT;链接＆LT; / A＆GT;
 

的.htaccess：

 重写规则^静态/(.*)$ /index.php?static=$1 [L]
 

的index.php：

 阵列（[静态] =＆GT;博弈技[-Arts实验室] =＆GT;）
 

解决方案

嗯，好吧。有趣。它似乎还有保持的符号专门躲过了特殊的解决方案。使用 [B] 标志的规则集。

 重写规则^静态/(.*)$ /index.php?static=$1 [L，B]
 

这是应该的时候插了 $ 1 占位符urlen code特殊字符。它只能与Apache 2.2的工作，但是我相信。

I am encountering a problem with a get parameter in conjunction with a htaccess rewrite rule. Below is the urlencode()'ed link; the rewrite rule I use to redirect to index.php, and lastly, a print_r($_GET) on the index.php. As you can see, the urlescaped ampersand is not part of the value for variable static, but instead and contrary to my expectation gets interpreted as a variable seperator. Why?

Initial link:

<a href="static/Game-Tech-%26-Arts-Lab">link</a>

.htaccess:

RewriteRule ^static/(.*)$ /index.php?static=$1 [L]

index.php:

Array ( [static] => Game-Tech- [-Arts-Lab] => )

解决方案

Ah, okay. Interesting. It seems there is a special solution for keeping that ampersand specifically escaped. Use the [B] flag for Rewriterules.

RewriteRule ^static/(.*)$ /index.php?static=$1 [L,B]

This is supposed to urlencode special characters when interpolating the $1 placeholder. It only works with Apache 2.2 however I believe.
