如何使PHP页面仅在某些预定义的IP地址上可用？

Question

我在代码点火器中编写一个脚本,我想制作一些只能用于某些ip范围的页面.如果超出该范围的其他人将打开它将被重定向到预定义的页面.我在代码点火器中寻找解决方案.请帮助我.

Answer 1

使用简单的IP地址查找脚本,如:

// Function to get the client IP address
function get_client_ip() {
    $ipaddress = '';
    if (getenv('HTTP_CLIENT_IP'))
        $ipaddress = getenv('HTTP_CLIENT_IP');
    else if(getenv('HTTP_X_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_X_FORWARDED_FOR');
    else if(getenv('HTTP_X_FORWARDED'))
        $ipaddress = getenv('HTTP_X_FORWARDED');
    else if(getenv('HTTP_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_FORWARDED_FOR');
    else if(getenv('HTTP_FORWARDED'))
       $ipaddress = getenv('HTTP_FORWARDED');
    else if(getenv('REMOTE_ADDR'))
        $ipaddress = getenv('REMOTE_ADDR');
    else
        $ipaddress = 'UNKNOWN';
    return $ipaddress;
}

并做出如下选择:

$whitelistedIPAddresses = array("127.0.0.1", "192.168.0.1");
if (!in_array(get_client_ip(), $whitelistedIPAddresses))
  exit;
