wordpress评论ip异常问题

gsls2008082024-08-08 15:31

在多层nginx中，获取到的ip为最后一个nginx的上层nginxip

具体获取评论ip的代码为

wp-includes/comment.php

if ( ! isset( $commentdata['comment_author_IP'] ) ) {
        $commentdata['comment_author_IP'] = $_SERVER['REMOTE_ADDR'];
    }

解决方法1

在wp-config中添加如下代码重写'REMOTE_ADDR'变量

// Set the real IP address for clients behind a proxy or load balancer.
function set_real_client_ip() {
    if ( ! empty( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) {
        // Check if multiple IPs exist in the header, take the first one.
        $ip_address_list = array_map( 'trim', explode( ',', $_SERVER['HTTP_X_FORWARDED_FOR'] ) );
        $real_ip = reset( $ip_address_list );
    } elseif ( ! empty( $_SERVER['HTTP_CLIENT_IP'] ) ) {
        // Fallback to HTTP_CLIENT_IP if available.
        $real_ip = $_SERVER['HTTP_CLIENT_IP'];
    } else {
        // Use REMOTE_ADDR as fallback.
        $real_ip = $_SERVER['REMOTE_ADDR'];
    }

    // Set the REMOTE_ADDR to the real IP address.
    $_SERVER['REMOTE_ADDR'] = $real_ip;
}

// Call the function to set the real IP address.
add_action( 'init', 'set_real_client_ip' );

方法2,安装reverse-proxy-comment-ip-fix插件

下载zip包上传到插件安装界面就可以

插件本质上在pre_comment_user_ip加了过滤器执行对应函数里的操作
