Question

我的PHP脚本执行以下操作

使用CURL以登录名和密码登录远程服务器，效果很好。 echo $result;显示已登录的页面内容。
其次，它的作用是访问内部页面（需要一个人登录）并检查页面是否被远程更改（更新）或不使用CURL。

我在"Access denied"中收到的错误是Part 2 of the code below，我认为Cookie在整个会话期间都没有持续存在？这是问题，我应该在代码中做些什么改变。

<?
//Part 1
$username="username; 
$password="pwd"; 
$url="http://abc.com/home?q=login&destination=filmmaker%2Fhome";
$cookie="cookie.txt"; 

$postdata = "name=".$username."&pass=".$password."&form_id=user_login&edit-name=".$username."&remember_me=1"; 



$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 

curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

echo $result;  

//Part 2

$curl = curl_init("http://abc.com/filmmaker/home");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_NOBODY, true);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_FILETIME, true);
$result = curl_exec($curl);

if ($result === false) {
    die (curl_error($curl)); 
}

$timestamp = curl_getinfo($curl, CURLINFO_FILETIME);
if ($timestamp != -1) { //otherwise unknown
    echo date("Y-m-d H:i:s", $timestamp); //etc
}
curl_close($ch);


?>

Answer 1

第2部分需要：

curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);

这将发送第1部分中CURLOPT_COOKIEJAR选项保存的cookie。
