我已成功通过curl登录网站,但现在我想重定向到要下载的文件。此文件需要登录cookie才能下载。我将如何重定向并使用以前保存的cookie?我尝试在登录成功后设置下面的URL但是没有用。
<?php
$username = "user";
$password = "pass";
$url = "https://www.example.com/login";
$urldl = "https://www.example.com/get-download/abc.xyz";
$cookie = "cookie.txt";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
if (curl_errno($ch)) die(curl_error($ch));
$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($response);
$token = $doc->getElementById("csrf_token")->attributes->getNamedItem("value")->value;
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_setopt($ch, CURLOPT_POST, true);
$params = array(
'username' => $username,
'password' => $password,
'csrf_token' => $token
);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
curl_exec($ch);
if (curl_errno($ch)) print curl_error($ch);
curl_setopt($ch, CURLOPT_URL, $urldl);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
curl_close($ch);
答案 0 :(得分:0)
您已启用CURLOPT_RETURNTRANSFER
,但实际上并未从curl_exec
// I want the result returned from exec
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// but I'm not gonna do anything with it...
curl_exec($ch);
因此,您应该将其分配给值set the header appropriately,然后打印响应。
$result = curl_exec($ch);
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="foo.bar"');
echo $result;
