从另一个站点自动登录到 wordpress 仪表板

Question

我想从另一个站点自动登录到 WP admin/dashboard 而不通过登录过程..我尝试了以下但没有运气：

<?php

$username="admin";
$password="mypasw";
$url="http://example.com/";
$cookie="cookie.txt";

$postdata = "log=". $username ."&pwd=". $password ."&wp-submit=Log%20In&redirect_to=". $url ."wp-admin/&testcookie=1";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url . "wp-login.php");
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt ($ch, CURLOPT_REFERER, $url . "wp-admin/");
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt ($ch, CURLOPT_POST, 1);
$result = curl_exec ($ch);
curl_close($ch);
echo $result;
exit;


?>

这有点像只向我显示仪表板页面，但我并没有真正登录，因为单击管理页面上的任何按钮只会重定向到与站点页面相同的页面.. :(

如果您有权访问您尝试登录的网站的文件。 您可以添加一个自动登录 php 脚本并将用户名和密码 $_POST 添加到此脚本中，例如：

if ($_POST) {

    $errors = array();

    $username = esc_sql($_REQUEST['username']);
    $password = esc_sql($_REQUEST['password']);
    $remember = esc_sql($_REQUEST['rememberme']);
    $remember = ($remember) ? "true" : "false";

    $login_data = array();
    $login_data['user_login'] = $username;
    $login_data['user_password'] = $password;
    $login_data['remember'] = $remember;
    $user_verify = wp_signon($login_data, true);

    if (is_wp_error($user_verify)) {
        $errors[] = 'Invalid username or password. Please try again!';
    } else {
        wp_set_auth_cookie($user_verify->ID);
        wp_redirect(admin_url());
        exit;
    }

}

Wordpress 代码参考：

• 登录功能： http : //codex.wordpress.org/Function_Reference/wp_signon
• 为管理员登录设置 cookie http://codex.wordpress.org/Function_Reference/wp_set_auth_cookie
• 获取管理页面网址： http : //codex.wordpress.org/Function_Reference/admin_url

希望能帮助到你。

编辑： $wpdb->e​​scape 自 Wordpress 3.6 版起已弃用，请改用 wpdb::prepare() 或 esc_sql()！ 我已将代码更改为使用 esc_sql()。

• esc_sql(): http://codex.wordpress.org/Function_Reference/esc_sql

试试这个完整的代码它工作 100% 第一个网站： http : //firstwebsite.com和第二个网站： http : //secondwebsite.com

现在，首先在您的第一个网站上创建一个链接，我们希望以登录用户的身份单击该链接以转到我们的第二个网站。 因此，在您的第一个网站中，在您想要的位置创建一个链接，如下所述：

<?php   global $current_user;
$second_website_url = 'http://secondwebsite.com'; // put your second website url
$user_email = $current_user->user_email;
$user_login = $current_user->user_login;
if($user_email != ''){

$email_encoded = rtrim(strtr(base64_encode($user_email), '+/', '-_'), '='); 
$user_login_encoded = rtrim(strtr(base64_encode($user_login), '+/', '-_'), '='); 
echo '<a href="'.$second_website_url.'/sso.php? 
key='.$email_encoded.'&detail='.$user_login_encoded.'" target="_blank">Link to 
second website</a>';
}?> 

现在，打开我们的第二个网站并创建一个新的 php 文件并将其命名为“sso.php”。 将此文件放在您的 root 安装中，只需将下面提到的代码复制粘贴到此文件中：

<?php

require_once( 'wp-load.php' ); //put correct absolute path for this file


global $wpdb;

if(isset($_GET['key']) && !empty($_GET['key'])){

$email_decoded = base64_decode(strtr($_GET['key'], '-_', '+/'));   
$username_decoded = base64_decode(strtr($_GET['detail'], '-_', '+/')); 

$received_email = sanitize_text_field($email_decoded);
$received_username = sanitize_text_field($username_decoded);


if( email_exists( $received_email )) {

        //get the user id for the user record exists for received email from database 
        $user_id = $wpdb->get_var($wpdb->prepare("SELECT * FROM ".$wpdb->users." WHERE user_email = %s", $received_email ) );

        wp_set_auth_cookie( $user_id); //login the previously exist user

        wp_redirect(site_url()); // put the url where you want to redirect user after logged in

}else {

        //register those user whose mail id does not exists in database 

        if(username_exists( $received_username )){

            //if username coming from first site exists in our database for any other user,
            //then the email id will be set as username
            $userdata = array(
            'user_login'  =>  $received_email,
            'user_email'  =>  $received_email, 
            'user_pass'   =>  $received_username,   // password will be username always
            'first_name'  =>  $received_username,  // first name will be username
            'role'        =>  'subscriber'     //register the user with subscriber role only
        );

        }else {

            $userdata = array(
            'user_login'  =>  $received_username,
            'user_email'  =>  $received_email, 
            'user_pass'   =>  $received_username,   // password will be username always
            'first_name'  =>  $received_username,  // first name will be username
            'role'        =>  'subscriber'     //register the user with subscriber role only
        );

        }


        $user_id = wp_insert_user( $userdata ) ; // adding user to the database

        //On success
        if ( ! is_wp_error( $user_id ) ) {
             
            wp_set_auth_cookie( $user_id); //login that newly created user
            wp_redirect(site_url()); // put the url where you want to redirect user after logged in

        }else{

            echo "There may be a mismatch of email/username with the existing record.
                  Check the users with your current email/username or try with any other account.";die;
        }


}

 die;
