Php 为项目创建scraper时出现CURL HTTP 302错误

我需要登录并保存一些页面，但即使登录后，保存cookie.txt它也会重定向回登录页面。看起来它没有登录

这是我的密码：

<?php
$ch = curl_init(); 
$cookie_file_path = 'cookie.txt'; 
$cookie_file_path = realpath($cookie_file_path); 
$data = array();
$data['ctl00$MainContent$txtUserName'] = "****";
$data['ctl00$MainContent$txtPassword'] = "****";

$postStr = "";

foreach($data as $key=>$d){
    $postStr .= $key.'='.urlencode($d).'&';
}

$postStr = substr($postStr,0,-1);

curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); 
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); 

curl_setopt($ch, CURLOPT_VERBOSE, TRUE); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
$agent = $_SERVER["HTTP_USER_AGENT"];
curl_setopt($ch, CURLOPT_USERAGENT, $agent); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); 

//new ones 
curl_setopt($ch, CURLOPT_HEADER, 1); 
curl_setopt($ch, CURLOPT_URL,"http://member.phonhadat.com/dang-nhap.htm"); 
curl_setopt($ch,CURLOPT_POST,TRUE);
curl_setopt($ch,CURLOPT_POSTFIELDS,$postStr);
curl_exec ($ch); // execute the curl command 
echo 'Curl error: ' . curl_error($ch); //no errrors 
curl_close ($ch); 
unset($ch); 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); 
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); 

curl_setopt($ch, CURLOPT_VERBOSE, TRUE); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt($ch, CURLOPT_USERAGENT, $agent); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); 

curl_setopt($ch, CURLOPT_URL,"http://member.phonhadat.com/thay-doi-thong-tin.htm"); 

//new ones 
curl_setopt($ch, CURLOPT_HEADER, 1); 

curl_exec ($ch); 
echo 'Curl error: ' . curl_error($ch); 
curl_close ($ch);  

?>

下面是我得到的旋度误差：

如果有人能帮我解决这个问题，我将不胜感激。

我刚刚查看了页面，用户/密码字段名为

ctl00$MainContent$txtservername/ctl00$MainContent$txtPassword

您是否尝试更改它？是的，我编辑了代码，但仍然出错。
