我已经为自己制作了一个使用 cURL 和 PHP 登录 Amazon 的测试项目，但经过几个小时的兜售，我想我不得不承认失败。我想知道是否有人能告诉我我下面的代码有问题吗？
除此之外，我还下载了我的 Amazon cookie 并将它们放在与 PHP 相同的目录中的一个名为“cookie.txt”的文件中
$username =""; // needs to be changed
$password = ""; // needs to be changed
$url = ""; // sign in url
$cookie = "cookie.txt";
$postdata = "email=".$username."&password=".$password;
$ch = curl_init();
curl_setopt ($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 ($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt ($ch, CURLOPT_REFERER, $url);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt ($ch, CURLOPT_POST, 1);
$result = curl_exec ($ch);
echo $result;
curl_close($ch);
