Nginx使用php args重写规则

我有2个网站，

http://localhost/bb – phpbb

http://localhost/dp – Drupal

我希望将$server_name/bb/ucp.php?mode=logout&sid=xxxxxredirect到$server_name/dp/user/logout ，sid应该被忽略。

• Nginx的WordPress重写多个子文件夹
• 使用IIS URL请求将多个浏览器请求redirect到一个站点
• GIF与Apache重写丢失了mimetypes
• Apache别名链接到另一个DocumentRoot
• 重写规则被忽略

我试过这个：

 location /bb/ { index index.php; if ($query_string ~* "mode=logout$") { rewrite ^/bb/ucp\.php http://$server_name/dp/user/logout redirect; } } 

这似乎不工作。 谁能帮忙？ 谢谢。

我也试过这个：

 location /bb/ { index index.php; if ($arg_mode ~* "logout") ## and = instead of ~* too. { rewrite ^/bb/ucp\.php http://$server_name/dp/user/logout redirect; } } 

但它也不起作用。

当前整个configuration：

 server { listen 80; server_name localhost; add_header X-Frame-Options "SAMEORIGIN"; client_max_body_size 500M; root /var/www; location / { index index.html index.htm index.php; try_files $uri @rewrite; } location /bb/ { index index.php; if ($arg_mode = "logout") { rewrite ^/bb/ucp\.php http://$server_name/dp/user/logout redirect; } } location @rewrite { # needed by Drupal rewrite ^/([^/]*)/(.*)(/?)$ /$1/index.php?q=$2&$args; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; fastcgi_param PATH_INFO $fastcgi_path_info; } } 

（不按预期工作）

 if ($arg_mode = "logout") { 

 if ($arg_mode = "logout") { rewrite ^/bb/ucp\.php http://$server_name/dp/user/logout redirect; }
