PHP | Paypal Rest API | java.lang.NullPointerException

我使用快速結賬REST API在Paypal上進行付款。我使用PHP中的CURL成功地檢索了我的令牌。然而，實際上進行付款的下一部分不起作用。PHP | Paypal Rest API | java.lang.NullPointerException

我得到以下錯誤：

顯示java.lang.NullPointerException（我beleive這個錯誤是來自PayPal？）

我曾嘗試通過代碼去，但我不明白我在做什麼因爲它都是簡單的結構。

我的代碼：

$payment_result_json = array(
         "intent" => "sale", 
         "redirect_urls" => array("return_url" => "http://paypal/paypal_return.php", "cancel_url" => "http://paypal/paypal_cancel.php"), 
         "payer" => array("payment_method" => "paypal"), 
         "transactions" => array(

          "amount" => array("amount" => array(
           "total" => "1", "currency" => "USD", "details" => array(
            "subtotal" => "1", "shipping" => "0", "tax" => "1", "shipping_discount" => "0" 
            ) 
          )), 

          "item_list" => array("quantity" => "1", "name" => "Item 1", "price" => "1", "currency" => "USD", "description" => "item1 desc","tax" => "1"), 
          "description" => "Tutoring lesson" 
         )); 

$post_headers = array("Authorization: Bearer $retreived_access_token"); 

$ch = curl_init("https://api.sandbox.paypal.com/v1/payments/payment"); 

curl_setopt($ch, CURLOPT_HEADER, false); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $post_headers); 

while(empty($payment_result)){ 
    $payment_result = curl_exec($ch); 
} 

if(empty($payment_result)){ 
    print curl_error($ch); 
}else{ 
    print $payment_result; 
} 

curl_close($ch); 

$payment_result_json = json_decode($payment_result); 

print_r($payment_result_json);

我有同樣的問題昨天。我解決了它添加此標頭： $post_headers = array("Authorization: Bearer $retreived_access_token", "Content-Type: application/json");

希望它有幫助
