一、关于Rewrite的分析
AVS默认推荐使用Apache环境运行,因为程序中自带.htaccess文件,内容如下:
#如果服务器报500错误注释这2行 Options -Indexes Options +FollowSymLinks #反注释下面几行,如果你想使用图片缓存 #<IfModule mod_expires.c> # ExpiresActive On # ExpiresDefault A1209600 # ExpiresByType text/html A1 #</IfModule> # Uncomment following lines if Apache doesnt support MultiViews! <IfModule mod_rewrite.c> RewriteEngine On # Uncomment the 2 lines below if you are using www.domain.com # as the baseurl for the site and users access your site # via domain.com (THIS IS REQUIRED FOR JQUERY TO WORK) #如果访问的不带www的域名则跳转到带www的域名 #e.g.: baidu.com => www.baidu.com RewriteCond %{HTTP_HOST} ^domain.com [NC] RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301] RewriteCond %{REQUEST_FILENAME} !-f #如果请求的不是文件 RewriteCond %{REQUEST_FILENAME} !-d #如果请求的不是目录 RewriteRule .* loader.php [L,QSA] #重写到loader.php处理请求 </IfModule>
对应的Nginx规则:
location / { #-f 判断是否文件 #-d 判断是否目录 #-e 判断是否文件或目录 if (!-e $request_filename){ rewrite ^(.*)$ /loader.php last; } }其中,last最为关键,之前调试的时候设为break,怎么都不行,百斯不得骑姐:)后来百度才明白这二者的区别
如果配置中存在N多个location,last匹配后还会继续循环匹配,而break则立即终止匹配。
参考文章:Nginx Rewrite研究笔记 nginx中的break与last指令区别
<?php //die('Only enable this script if you dont have support for MultiViews'); $relative = ''; $loaders = array( 'ajax' => 1, 'album' => 1, 'albums' => 1, 'blog' => 1, 'blogs' => 1, 'captcha' => 1, 'categories' => 1, 'community' => 1, 'confirm' => 1, 'error' => 1, 'feedback' => 1, 'feeds' => 1, 'game' => 1, 'games' => 1, 'index' => 1, 'invite' => 1, 'loader' => 1, 'login' => 1, 'logout' => 1, 'lost' => 1, 'mail' => 1, 'notice' => 1, 'notices' => 1, 'photo' => 1, 'requests' => 1, 'search' => 1, 'signup' => 1, 'static' => 1, 'stream' => 1, 'upload' => 1, 'user' => 1, 'users' => 1, 'video' => 1, 'videos' => 1, 'edit' => 1 ); $query = ( isset($_SERVER['QUERY_STRING']) ) ? $_SERVER['QUERY_STRING'] : NULL; $request = str_replace($relative, '', $_SERVER['REQUEST_URI']); $request = str_replace('?' .$query, '', $request); $request = explode('/', trim($request, '/')); if (isset($request['0'])) { $page = $request['0']; if (isset($loaders[$page])) { require $page. '.php'; } else { header('HTTP/1.0 404 Not Found'); die(); } } else { header('HTTP/1.0 404 Not Found'); die(); }
这段代码就是检测/xxx允许访问的页面,然后访问对应的.php
eg: http://www.xxx.com/video实际上访问的是/video.php
