wordpress one time log out by DELETE COOKIE

[yaoyao1128]

Hi everyone,
I use the sso plugin with wordpress and find it cannot log out at the same time. So I found that way. It might a little bit dangerous because it just delete cookie. Is there any other way to log out at same time?

This is my way to logout

Logout wordpress -> Delete Cookie of NodeBB -> return to nodebb homepage

Step 1: create this php file under wordpress dir

<?php
require( dirname(__FILE__) . '/wp-load.php' );
wp_logout();
setcookie("express.sid", FALSE, time()-YEAR_IN_SECONDS, '', "~~FORUM_COOKIE_DOMAIN~~");

header("Location: http://~~FORUM_COOKIE_DOMAIN~~/");
exit;

Step 2 : make NodeBB can access this file when logout
When we logout form NodeBB, it send us to /logout and a string.
So I use the nginx as proxy server to access php files. here is my config file of nginx

 location ~ .*\.php$ {
         rewrite ^/(.*) /$1 break;
        proxy_pass http://localhost:82;
        proxy_buffer_size  128k;
        proxy_buffers   32 32k;
        proxy_busy_buffers_size 128k;
}
location / {
        rewrite /logout  http://~~~FORUM_DOMAIN~~~/logoutbbs.php break;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://io_nodes;
        proxy_redirect off;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
