【问题描述】：

我正在测试 paypal 集成，在我的 apache 服务器上使用 vhost -> test.it/paypal 进行 php 演示测试。 我使用 Express Checkout + 服务器端 REST (cURL)。 我的 js 添加 PayPal 按钮是：

<script>

      var CREATE_PAYMENT_URL  = 'http://test.it/paypal/create-payment.php';
      var EXECUTE_PAYMENT_URL = 'http://test.it/paypal/execute-payment.php';

      paypal.Button.render(

          env: 'sandbox', // Or 'production',

          commit: true, // Show a 'Pay Now' button

          locale: 'it_IT',

          style: 
              size: 'small',
              color: 'blue',
              shape: 'pill',
              label: 'checkout'
          ,

          commit: true, // Show a 'Pay Now' button

          payment: function() 

              // Make a call to the merchant server to set up the payment

              return paypal.request.post(CREATE_PAYMENT_URL).then(function(res) 
                  //return res.payToken;
                  console.log(res);
                  return res.paymentID;
              );
          ,

        // Wait for the payment to be authorized by the customer

        onAuthorize: function(data) 
          //alert(data.payerID);
            return paypal.request.post(EXECUTE_PAYMENT_URL, 
                paymentID: data.paymentID,
                payerID:   data.payerID
            ).then(function(res) 
              /* Go to a success page */
                console.log('SUCCESS!!!!!!!!!');
                console.log(res);
                // The payment is complete!
                // You can now show a confirmation message to the customer
                alert('pagamento completato');
            ).catch(function (err) 
              /* Go to an error page  */
              console.log('ERROR!!!!!!!!!');
              console.log(data);
              console.log(err);
          );
        

      , '#paypal-button');
    </script>

create-payment.php如下：

<?php
session_start();
include 'config.php';

// autenticazione per ottenere user token
$url_wbs="https://api.sandbox.paypal.com/v1/oauth2/token";


$ch = curl_init();

// id web experience profile
$experience_profile_id="XP-V52K-SKNH-FK7Y-HLYQ";

curl_setopt($ch, CURLOPT_URL, $url_wbs);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);

curl_setopt($ch, CURLOPT_USERPWD, $clientId.":".$secret);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");

$result = curl_exec($ch);
curl_close($ch);
if(empty($result))die("Error: No response.");
else

    $obj=json_decode( $result );

   //var_dump($obj->access_token);
   $_SESSION['token']=$obj->access_token;

   // imposto il web profile ottenendone l'id
   $header_rest_call[]='Authorization: Bearer '.$obj->access_token;


   $json_body='

  "experience_profile_id":"'.$experience_profile_id.'",
  "redirect_urls":
  
    "return_url": "http://test.it/paypal/checkout.php",

      ]
    ,
    "description": "The payment transaction description.",
    "invoice_number": "merchant invoice",
    "custom": "merchant custom data"
  ]
';

   $obj_payment=get_obj_json($payment_creation_url,$header_rest_call,$json_body,'POST');

   //var_dump($obj_payment->id);
   $response=array(
     'paymentID'=>$obj_payment->id
   );

   echo json_encode($response);

?>

execute-payment.php如下：

<?php
session_start();
include 'config.php';


   // imposto il web profile ottenendone l'id
   $header_rest_call[]='Authorization: Bearer '.$_SESSION['token'];

  // indirizzo wbs per pagamento
  $url_payment="https://api.sandbox.paypal.com/v1/payments/payment/".$_POST['paymentID']."/execute/";

  $json_body='
    "payer_id": "'.$_POST['payerID'].'";
  ';

  $obj_payment=get_obj_json($url_payment,$header_rest_call,$json_body,'POST');

  echo json_encode($obj_payment);


?>

当我点击 paypal 按钮时，paypal 登录表单会正确显示购买数据，我输入凭据，最后点击“立即付款” 按钮。好像支付成功了..但是在沙盒账户->活动->没有transitions/payments的痕迹..？

【问题讨论】：

这些是你真正的clientId和secret吗？我不会发布那些...

匆忙拍摄.. 现在我删除了该应用程序。谢谢

【参考方案1】：

问题在于付款/执行请求的 json 格式错误。

$json_body='
"payer_id": "'.$_POST['payerID'].'";

';

在 -> $_POST['payerID'].'之后有一个分号我错误输入了。'"

现在可以了！

【讨论】：

我想在我的网站上集成相同的内容，你能告诉我 config.php 中有什么吗？我收到错误未捕获错误：调用未定义函数 get_obj_json()
