paypal php 信用卡支付 returns 401

Question

我正在尝试通过 paypal REST API 服务进行信用卡付款，我可以获取访问令牌，但每次尝试进行信用卡付款时我都会收到 401。

我的示例在 .NET 上运行完美，但在 PHP 上运行不佳。请指教

$json = '{"intent":"sale","redirect_urls":{"return_url":"","cancel_url":""},"payer":{"payment_method":"credit_card","funding_instruments":[{"credit_card":{"number":"4417119669820331","type":"visa","expire_month":11,"expire_year":2018,"cvv2":"874","first_name":"Betsy","last_name":"Buyer","billing_address":{"line1":"111 First Street","city":"Saratoga","state":"CA","postal_code":"95070","country_code":"US"}}}]},"transactions":[{"amount":{"total":"200","currency":"USD"},"description":"Credit Card Payment - 0"}]}';

$Url = "https://api.sandbox.paypal.com/v1/payments/payment";
$AccessToken = GetAccessToken();
echo "Bearer ".$AccessToken;
echo "<br><br>";
$headers = array("Authorization" => "Bearer ".$AccessToken, "Content-Type" => "text/json", "Content-length" =>strlen($json));

$handle = curl_init($Url);


curl_setopt($handle,CURLOPT_HTTPHEADER,$headers);   
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $json);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
$response   = curl_exec($handle);
$info = curl_getinfo($handle);
$error= curl_error ( $handle );
curl_close($handle);

var_dump($info);
echo "<br><br>";
var_dump($error);
echo "<br><br>";
var_dump($response);
