在PHP中使用CURL或fsockopen的Wordpress自动登录

<?php

    'log' => $username,

    'wp-submit' => 'Log In',
    'redirect_to' => 'http://your-wordpress-site.com/wp-admin/',
    'testcookie' => '1'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $login_url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($login_data));
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch);

echo $result;
