我自己做了一个使用cURL和PHP登录亚马逊的测试项目，但经过几个小时的圈子，我想我不得不承认失败。我想知道是否有人可以告诉我，我的代码是否出错？
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，名为＆＃39; cookie.txt＆＃39;
$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);
