环境如何标记ê作品在.htaccessmod-rewrite [英] How the Environment tag E works in .htaccess mod rewrite

问题描述

我有一个htaccess文件以下规则

I have the following rules in a htaccess file

RewriteEngine On
RewriteRule mytest.php test.php
RewriteCond %{QUERY_STRING} !done
RewriteRule (.*)  $1?done [E=TEST:itworks]

文件test.php的仅仅是

The file test.php is simply

<?php
echo "TEST = " . getenv('TEST'); 
?>

当我输入请求URI test.php的，环境变量TEST的定义，它呼应测试= itworks。但是，当我输入请求URI mytest.php，它也进入test.php的，但是环境变量的测试是没有定义，它呼应测试='。

When I enter the request uri test.php, the environment variable TEST is defined and it echoes 'Test = itworks'. However, when I enter the request uri mytest.php, it also goes to test.php, but the environment variable TEST is not defined and it echoes 'Test =' .

是预期的行为？如果是在我的环境中的错误，没关系。否则，也许人们可以使用简单的例子来向我解释它是如何工作的。

Is that the expected behavior? If it is a bug in my environment, never mind. Otherwise, perhaps one could use that simple case to explain to me how it works.

推荐答案

当你通过 mytest.php ，还有通过mod_rewrite的另一轮。

When you go through mytest.php, there is an additional round through mod_rewrite.

环境变量然后prefixed与重定向_ 。如果检查 REDIRECT_TEST ，你会看到所需的输出

The environment variables are then prefixed with REDIRECT_. If you check for REDIRECT_TEST, you will see the desired output

<?php
echo "TEST = " . getenv('TEST') . "/" . getenv('REDIRECT_TEST');

请参阅可用变量的一些细节。
