宝PHP REST API

我创建一个PayPal支付用PHP，这是到目前为止的代码：宝PHP REST API

$ch = curl_init(); 
     $clientId = "clientID"; 
     $secret = "secret"; 

     curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/oauth2/token"); 
     curl_setopt($ch, CURLOPT_HEADER, false); 
     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
     curl_setopt($ch, CURLOPT_POST, true); 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
     curl_setopt($ch, CURLOPT_USERPWD, $clientId.":".$secret); 
     curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials"); 

     $result = curl_exec($ch); 

     if(empty($result))die("Error: No response."); 
     else 
     { 
       $json = json_decode($result); 
        //print_r($json->access_token); 
        if ($_POST['creditcard'] == 'paypal') { 
         $data = '{ 
          "intent":"sale", 
          "redirect_urls":{ 
          "return_url":"http://returnurl.com", 
          "cancel_url":"http://returnurl.com" 
          }, 
          "payer":{ 
          "payment_method":"paypal" 
          }, 
          "transactions":[ 
          { 
          "amount":{ 
          "total":"' . preg_replace("/[^0-9,.]/", "", $order_price) .'", 
          "currency":"' . $currency_code .'" 
          }, 
          "description":"' . ucfirst($type) . ' Logo Purchase. ' . '" 
          } 
          ] 
          }'; 

          curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/payments/payment"); 
          curl_setopt($ch, CURLOPT_POST, true); 
          curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
          curl_setopt($ch, CURLOPT_HTTPHEADER, array(
          'Content-Type:application/json', 
          "Authorization: Bearer " . $json->access_token, 
          "Content-length: ".strlen($data)) 
          ); 
          print_r($data); 
          $result = curl_exec($ch); 

          if(empty($result))die("Error: No response."); 
          else { 
           $json_output = json_decode($result); 
           print_r($result); 

           if(isset($json_output->{'links'}[2]->{'href'})) 
            $_SESSION['execute_url'] = $json_output->{'links'}[2]->{'href'}; 
           if(isset($json_output->{'links'}[1]->{'href'})) 
            header('Location:' .$json_output->{'links'}[1]->{'href'}); 
          } 

        } 

       } 

     curl_close($ch);

我签我的测试帐号，我重定向到重定向URL。所以我假设一切工作正常。接下来的部分是我无法弄清楚的。我正在尝试在这里执行付款。

我是否使用从上述以前代码收到的付款网址？

我试着这样做：

      $data = '{ "payer_id" : "' .$_GET['PayerID'] . '" }'; 
          curl_setopt($ch, CURLOPT_URL, $stored_execute_url; 
          curl_setopt($ch, CURLOPT_POST, true); 
          curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
          curl_setopt($ch, CURLOPT_HTTPHEADER, array(
          'Content-Type:application/json', 
          "Authorization: Bearer " . $_GET['token'], 
          "Content-length: ".strlen($data)) 
          ); 
          print_r($data); 
          $result = curl_exec($ch); 

          if(empty($result))die("Error: No response.");

所有我得到的是“错误：没有响应”

我一直在关注这个链接https://developer.paypal.com/webapps/developer/docs/integration/web/accept-paypal-payment/，我能够得到，直到最后一部分。

我想通了。我使用PayPal返回网址中给出的令牌。我尝试使用原始的令牌，并购买了。贝宝返回您的网站时，令牌是否有目的？ – Marquisk2
