贝宝订单API Express Checkout-CaptureOrder ID问题

问题描述

有些初学者,但是我很难理解Paypal API结帐的一些演练。我对PHP很好,但是还没有完全了解JavaScript *。

因此,我已经获得了Paypal API上所示的检出按钮的客户端JAvascript,如下所示:

<script>
            paypal.Buttons(
                {
                env: 'sandbox',// sandbox | production
                     commit: true,createOrder: function() {
                        
                      return fetch('samples/AuthorizeIntentExamples/CreateOrder.php',{
                         method: 'post',headers: {
                          'content-type': 'application/json'
                        },})                       
                          .then(function(res) {
                            return res.json();
                          }).then(function(data) {
                            return data.id; // Use the same key name for order ID on the client and server
                          });

                    },onApprove: function(data) 
                    {
                      return fetch('samples/AuthorizeIntentExamples/CaptureOrder.php',{
                    method:'post',headers: {
                      'content-type': 'application/json','id':data.id
                    },body: JSON.stringify({
                      orderID: data.id
                    })
                  }).then(function(res) {
                    return res.json();
                  }).then(function(details) {
                    alert('Transaction funds captured from ' + details.payer_given_name);
                  })
                }

                }).render('#paypal-button-container');
        </script>

代码的CreateOrder端工作正常。我收到带有付款ID等的JSON。但是,我很难理解如何将OrderID传递给CaptureOrder函数。贝宝似乎避开了这个问题,只是在captureOrder函数中声明“ PUT ORDER ID HERE”:

        namespace Sample\AuthorizeIntentExamples;

require ($_SERVER['DOCUMENT_ROOT']. '/vendor/autoload.php');
include ($_SERVER['DOCUMENT_ROOT'].'/vendor/paypal/paypal.php');

use PayPalCheckoutSdk\Payments\AuthorizationsCaptureRequest;
use Sample\PayPalClient;

class CaptureOrder
{
    /**
     * Below method can be used to build the capture request body.
     * This request can be updated with required fields as per need.
     * Please refer API specs for more info.
     */
    public static function buildRequestBody()
    {
        return '{
                  "intent": "CAPTURE","purchase_units": [
                    {
                      "amount": {
                        "currency_code": "GBP","value": "100.00"
                      }
                    }
                  ]
                }';
    }
    

        /**
         * Below function can be used to capture order.
         * Valid Authorization id should be passed as an argument.
         */
        public static function captureOrder($authorizationId,$debug=false)
        {
            $request = new AuthorizationsCaptureRequest($authorizationId);
            $request->body = CaptureOrder::buildRequestBody();
            $client = PayPalClient::client();
            $response = $client->execute($request);
    
            if ($debug)
            {
               /* print "Status Code: {$response->statusCode}\n";
                print "Status: {$response->result->status}\n";
                print "Capture ID: {$response->result->id}\n";
                print "Links:\n";
                foreach($response->result->links as $link)
                {
                    print "\t{$link->rel}: {$link->href}\tCall Type: {$link->method}\n";
                }
                // To toggle printing the whole response body comment/uncomment below line */
                echo json_encode($response->result,JSON_PRETTY_PRINT),"\n";
            }
            return $response->result;
        }
    }
    
        /**
         * Driver function for invoking the capture flow.
         */
        if (!count(debug_backtrace()))
        {
           CaptureOrder::captureOrder('ORDER ID HERE',true);
        }

我是否需要将CreateOrder的JSON结果存储在SLQ数据库中并从那里调用订单号以捕获订单,还是我丢失了某些东西,并且Paypal工作流程中的客户端JavaScript *代码在Approve上发布了orderID? >


更新:

所以我一直在玩耍,我不明白为什么批准后没有将订单ID发送到CaptureOrder。

onApprove: function(data) {
  return fetch('/my-server/capture-paypal-transaction',{
    headers: {
      'content-type': 'application/json'
    },**body: JSON.stringify({
      orderID: data.id
    })**
  }).then(function(res) {
    return res.json();
  }).then(function(details) {
    alert('Transaction funds captured from ' + details.payer_given_name);
  })
}

尽管在CreateOrder阶段在data.id中返回了orderID,但orderID似乎不在这里。

我收到以下错误“未捕获的TypeError:无法在“ Window”上执行“ fetch”:使用GET / HEAD方法的请求不能具有主体”。尽管关注了PayPal文档。

然后我尝试了标题中的POST数据

onApprove: function(data) {
      return fetch('/my-server/capture-paypal-transaction',{
        headers: {
          'content-type': 'application/json','id': data.id
        }
      }).then(function(res) {
        return res.json();
      }).then(function(details) {
        alert('Transaction funds captured from ' + details.payer_given_name);
      })
    }

这停止了未捕获的错误,但是在帖子“ id”中发送的数据未定义。然后,导致API返回“找不到资源ID”。

我只是似乎不了解JAvaScript如何在CreateOrder函数和OnApprove函数之间传递OrderID。

尽我所能学习,但是我的贝宝(Paypal)文档似乎有很多不足或遗漏之处。
