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>PHP简单模拟登录功能实例分享
