这篇文章主要介绍了PHP简单实现模拟登陆功能,涉及php使用curl实现模拟登陆的相关操作技巧,需要的朋友可以参考下

本文实例讲述了PHP简单实现模拟登陆功能。分享给大家供大家参考，具体如下：

在不考虑验证码的情况一下，php实现模拟登陆，网上给的办法一般是采用curl来模拟实现，但是curl实现的是服务器端与服务器端建立了会话，只能模拟登陆之后获取登陆之后的数据，无法将cookie信息种植到客户端上（至少目前本人查找没有找到办法）最后自己通过隐藏的iframe来实现。

1、curl实现模拟登陆的代码，（只是实现服务器与服务器建立会话，其实并没有在客户端与服务器之间建立会话）

<?php
$cookie_jar = tempnam(&#39;./tmp&#39;,&#39;cookie&#39;);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, &#39;http://192.168.0.22/logincheck.php&#39;);
curl_setopt($ch, CURLOPT_POST, 1);
$request = &#39;UNAME=admin&PASSWORD=123456&#39;;
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
//把返回来的cookie信息保存在$cookie_jar文件中
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar);
//设定返回的数据是否自动显示
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//设定是否显示头信息
curl_setopt($ch, CURLOPT_HEADER, false);
//设定是否输出页面内容
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_exec($ch);
curl_close($ch);
//get data after login
$ch2 = curl_init();
curl_setopt($ch2, CURLOPT_URL, &#39;http://192.168.0.22/general/&#39;);
curl_setopt($ch2, CURLOPT_HEADER, false);
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_COOKIEFILE, $cookie_jar);
$orders = curl_exec($ch2);
echo $orders;
exit;
echo &#39;<pre class="brush:php;toolbar:false">&#39;;
echo strip_tags($orders);
echo &#39;

'; curl_close($ch2); ?>

2、通过隐藏的iframe实现客户端与服务器端的通信（肯能带来一定的安全隐患）

<html>
<title></title>
<body>
<?
$goURL="http://192.168.0.22/general/email/";
?>
<iframe name="hiddenLoginFrame" onload="get_pass()" src="ceshi1.php"  id="hiddenLoginFrame" width=0 height=0 frameborder=0 scrolling=no style="display:none;">
</iframe>
<script Language="JavaScript">
  function get_pass()
  {
    window.open("<?=$goURL ?>");
    window.close();
  }
</script>
</body>
</html>

ceshi1.php

<html>
<head>
  <title>ceshi</title>
</head>
<body onload="get_pass1();">
<form name="form1" method="post" target="hiddenLoginFrame" action="http://192.168.0.22/logincheck.php">
  <input type="text" value="admin" name="UNAME">
  <input type="text" value="123456" name="PASSWORD">
</form>
</body>
<script Language="JavaScript">
  function get_pass1()
  {
    //document.form1.action=u_url;
    document.form1.submit();
  }
</script>
</html>
