如何使用脚本模仿登陆过程_PHP教程

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。

name:
password:

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：

$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 "

".nl2br($resp);

fclose($fsp);

}
?>
