我已经在我的应用中启用了未来的付款权限并使用了开发者信息中心。但还没有正常工作请找错误 http://developer.paypal.com/并登录 https://developer.paypal.com/developer/accountStatus在那里你可以看到你有什么许可。
$data = array(
"intent" => "authorize",

"payment_method" => "paypal"
),
"transactions" => array(
array("amount" => array(

"total" => "1.88"
),
"description" => "future of sauces")
));
$data_string = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/payments/payment");
$headers = array(

$result = curl_exec($ch);

curl_close($ch);

我制作了一个Paypal模块，希望这段代码可以帮到你。
$result_json = json_decode($result);
/* Check if authentication is valid */
if (isset($result_json->access_token))
{
$enc_data = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.sandbox.paypal.com/v1/payments/payment');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, !in_array($_SERVER['REMOTE_ADDR'], array('127.0.0.1', '::1')));
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $enc_data);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Authorization: Bearer '.$result_json->access_token,
'PayPal-Client-Metadata-Id: ************'
));
$result = curl_exec($ch);
$json_result = json_decode($result);
curl_close($ch);
}
json_encode（$ data）有一些额外的信息可能对您可能尝试的事务没有用，但这只是一个例子。

"intent": "sale",
"payer": {
"payment_method": "credit_card",
"payer_info": {
"email": "...",
"shipping_address": {
[...]
}
},
"funding_instruments": [
{
"credit_card": {

}
}
}
]
},
"transactions": [
{
"amount": {
"total": 32.91,
"currency": "USD"
},
"item_list": {
"items": [

由于我没有从任何人那里得到任何解决方案，所以我逐步挖掘了我的代码并找到了解决方案。
