我正在尝试将 Paypal 与 PHP 集成，但现在我收到以下消息：

“系统中未找到传入的令牌”

这是我的代码。我哪里错了？

这是我获取令牌的代码，我已成功获取该令牌。

$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => "https://api.sandbox.paypal.com/v1/oauth2/token",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_USERPWD => $PAYPAL_CLIENT_ID.":".$PAYPAL_SECRET,
    CURLOPT_POSTFIELDS => "grant_type=client_credentials",
    CURLOPT_HTTPHEADER => array(
    "Accept: application/json",
    "Accept-Language: en_US"
    ),
));
$result= curl_exec($curl);
$array=json_decode($result, true); 
$token=$array['access_token'];

在这里我尝试集成 v1/ payment API：

$ch = curl_init();
$data = '{
"intent": "sale",
    "payer": {
    "payment_method": "credit_card",
    "payer_info": {
    "email": "'.$email.'",
    "shipping_address": {
    "recipient_name": "'.$fname.' '.$lname.'",
    "line1": …
