Nginx rewrite rules with php args

hlx98007 asked:

I have 2 websites,

http://localhost/bb — phpbb

http://localhost/dp — Drupal

I wish to redirect $server_name/bb/ucp.php?mode=logout&sid=xxxxx to $server_name/dp/user/logout, the sid should be ignored.

I’ve tried this:

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

It seems not working. Could anyone help? Thanks.


I tried this too:

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

but it doesn’t work either.


Current Whole config:

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;
    }
}

(Doesn’t work as expected)

My answer:


You should just check the argument value directly.

if ($arg_mode = "logout") {
