查看他的登陆页面的代码, 看他提交到哪个页面, 变量是什么。
<form method="post" action="login.jsp"> <table align="center" width="40%" style="FONT-SIZE: 12px" border="0" cellpadding="0" cellspacing="2"> <tr> <td width="30%" align="right" bgcolor="#0073AA" style="FONT-SIZE: 12px;color:#ffffff">name:</td> <td width="70%"><input type="text" size="30" name="username"></td> </tr> <tr> <td width="30%" align="right" bgcolor="#0073AA" style="FONT-SIZE: 12px;color:#ffffff">password:</td> <td width="70%"><input type="password" size="32" name="passwd"></td> </tr> <tr> <td colspan="2" align="right"> <input type="submit" name="submit" value="Login"> <input type="button" name="submit" value="regest" onclick="location.href='regest.jsp'"> </td> </tr> </table> </form>
很明显, 如果你要登陆, 你需要把username, passwd, submit这几个变量post到login.jsp, 而且submit=Login
用以下代码:
<?php $postData = "username=your_name&password=your_password&Submit=Login"; $posturl = "http://......../../login.jsp"; $postUrl = parse_url($posturl); $host = $postUrl[host] ? $postUrl[host] : ""; $port = $postUrl[port] ? $postUrl[port] : 80; $path = $postUrl[path] ? $postUrl[path] : "/"; $fsp = fsockopen($host, $port, &$errno, &$errstr, 30); if(!$fsp){ print "\nopen socket failed\n"; }else{ fwrite($fsp, "POST ".$path." HTTP/1.1\r\n"); fwrite($fsp, "Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*\r\n"); fwrite($fsp, "Accept-Language: zh-cn\r\n"); fwrite($fsp, "Content-Type: application/x-www-form-urlencoded\r\n"); fwrite($fsp, "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon)\r\n"); fwrite($fsp, "Host:".$host."\r\n"); fwrite($fsp, "Content-Length: ".strlen($postData)."\r\n\r\n"); fwrite($fsp, $postData); $resp = ""; do{ if(strlen($out=fread($fsp, 1024)) == 0) break; $resp .= $out; }while(true); echo "<br><br>".nl2br($resp); fclose($fsp); } ?>
