mod_rewrite使用PATH_INFO旋转关闭重写的附加子请求

标签： apache .htaccess mod-rewrite

假设我想将以/test/开头的所有请求路由到单个PHP文件info.php。我可以通过将原始%{REQUEST_URI}传递为：

来完成此操作

  1. 查询字符串参数，如

    info.php?request_uri=/test/some/path

    或

  2. PATH_INFO - 紧跟info.php之后的路径字符串，如

    info.php/test/some/path

    3. 还有其他方法（例如环境变量），但我的问题是关于使用PATH_INFO时的奇怪行为。

    问题在于，根据重写日志，PATH_INFO方法比查询字符串方法再生成一个子请求。

    有人可以解释为什么会这样吗？

    详细

    DOCUMENT_ROOT位于/var/www。 httpd -V的第一行是：

    Server version: Apache/2.2.15 (Unix)

    PATH_INFO

    /var/www/test/.htaccess文件的内容如下：

    DirectoryIndex disabled
DirectorySlash off
Options +FollowSymLinks -MultiViews

RewriteEngine on

# Only perform the rewrite for first round of mod_rewrite processing.
RewriteCond %{ENV:REDIRECT_STATUS} =""
# Pass current path as PATH_INFO to PHP script.
RewriteRule ^ info.php%{REQUEST_URI}

    /test/some/path的请求产生以下重写输出：
