This article mainly introduces the simple implementation of the simulated login function in PHP, and involves the related operating skills of PHP using curl to achieve simulated login. Friends in need can refer to it

The example of this article tells the simple implementation of the simulated login function in PHP . Share it with everyone for your reference, the details are as follows:

Without considering the verification code, PHP implements simulated login. The method given on the Internet is generally to use curl to simulate the implementation, but curl implements the server-side and The session is established on the server side, and it can only simulate the login and obtain the data after login. It cannot plant the cookie information on the client (at least I haven't found a way to find it so far). Finally, I can achieve it through a hidden iframe.

1. Curl implements the code for simulated login (it only implements the establishment of a session between the server and the server, but does not actually establish a session between the client and the server)

<?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); ?>

Copy after login

2. Realize communication between client and server through hidden iframe (may bring certain security risks)

<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>

Copy after login

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>

Copy after login
