本文執行個體講述了PHP簡單實現類比登陸功能。分享給大家供大家參考，具體如下：
在不考慮驗證碼的情況一下，php實現類比登陸，網上給的辦法一般是採用curl來類比實現，但是curl實現的是伺服器端與伺服器端建立了會話，只能類比登陸之後擷取登陸之後的資料，無法將cookie資訊種植到用戶端上（至少目前本人尋找沒有找到辦法）最後自己通過隱藏的iframe來實現。
1、curl實現類比登陸的代碼，（只是實現伺服器與伺服器建立會話，其實並沒有在用戶端與伺服器之間建立會話）
<?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, $request);//把返回來的cookie資訊儲存在$cookie_jar檔案中curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar);//設定返回的資料是否自動顯示curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//設定是否顯示頭資訊curl_setopt($ch, CURLOPT_HEADER, false);//設定是否輸出頁面內容curl_setopt($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($ch2);?>
2、通過隱藏的iframe實現用戶端與伺服器端的通訊（肯能帶來一定的安全隱患）
<html><title></title><body><?$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>Start building with 50+ products and up to 12 months usage for Elastic Compute Service
