php实现登录tplink WR882N获取IP和重启的方法

<?php

function getContent($url)
{
  // 解悉url
  $temp = parse_url($url);
  $query = isset($temp['query']) ? $temp['query'] : '';

    'Cookie: Authorization=Basic ' . base64_encode("admin:admin"),  // 注意这里的cookie认证字符串
    "Referer: http://{$temp['host']}/",
    'User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1)',
    "Content-length: 380",
    "Connection: Close"
  );
  $curl = curl_init(); // 启动一个CURL会话
  curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址
  curl_setopt($curl, CURLOPT_HTTPHEADER, $header); //设置头信息的地方
  curl_setopt($curl, CURLOPT_TIMEOUT, 60); // 设置超时限制防止死循环
  curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回
  $content = curl_exec($curl); // 执行操作
  curl_close($curl);
  return $content;
