PHP简单模拟登录功能实例分享

1、curl实现模拟登录的代码,(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('./tmp','cookie');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://192.168.0.22/logincheck.php');
curl_setopt($ch, CURLOPT_POST, 1);
$request = 'UNAME=admin&PASSWORD=123456';
curl_setopt($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, 'http://192.168.0.22/general/');
curl_setopt($ch2, CURLOPT_HEADER, false);
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_COOKIEFILE, $cookie_jar);
$orders = curl_exec($ch2);
echo $orders;
exit;
echo '<pre>';
echo strip_tags($orders);
echo '</pre>';
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>
