我正在尝试在 Groupon Merchant 中实现兑换优惠券的方式。

客户服务告诉我没有 API，所以我试图通过 CURL 请求来实现。

我可以提取 CSRF，但是无论我做什么，在发送数据时，我总是收到 403 错误。

如果我发送 CURLOPT_USERAGENT 我也会收到错误 403。

我不知道这是否与为标题发送一系列 cookie 有关。

所以我不知道我是做错了什么还是做不到。

有没有人知道如何做到这一点，目前我只是在尝试登录。



$url = "https://www.groupon.es/merchant/center/login";
$username = "xxxxx";
$password = "xxxxx";

$sh = curl_share_init();
curl_share_setopt($sh, CURLSHOPT_SHARE, CURL_LOCK_DATA_COOKIE);

//$cookie = 'C:/Temp/cookies.txt';

//Initialize Handle
$handle1 = curl_init();
curl_setopt($handle1, CURLOPT_SHARE, $sh);
curl_setopt($handle1, CURLOPT_URL, $url);
//curl_setopt($handle1, CURLOPT_USERAGENT,'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/32.0.1700.107 Chrome/32.0.1700.107 Safari/537.36');
curl_setopt($handle1, CURLOPT_RETURNTRANSFER, true);
// get headers too with this line
curl_setopt($handle1, CURLOPT_HEADER, 1);
curl_setopt($handle1, CURLOPT_HEADERFUNCTION,'header_callback');
//curl_setopt($handle1, CURLOPT_COOKIEJAR, $cookie);
//curl_setopt($handle1, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($handle1, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($handle1, CURLOPT_SSL_VERIFYPEER, 0);

//Execute Request
$output = curl_exec ( $handle1 );
var_dump($cookies);
print($output);
exit();

libxml_use_internal_errors(true);
$dom = new DomDocument();
$dom->loadHTML($output);
libxml_use_internal_errors(false);
$tokens = $dom->getElementsByTagName("input");
if(!$tokens){
    throw new Exception("Error");
}else{
    echo ("Tokens: ". $tokens->length . "<br>");
}

for ($i = 0; $i < $tokens->length; $i++)
{
    $meta = $tokens->item($i);
    if($meta->getAttribute('name') == '_csrf'){
        $t = $meta->getAttribute('value');
        echo "Not Found</ br>". $t;
    }
}

$params = array(
    "redirect_uri" => "/merchant/center?mid=xxxxx",
    "email" => $username,
    "password" => $password,
    '_csrf' => $t,
    "mid" => "xxxxx"

$output = curl_exec ( $handle2 );

curl_share_close($sh);

curl_close ( $handle1 );
curl_close ( $handle2 );
我已将私人数据更改为 xxxxx。

谢谢你！
