Question

Когда я пытаюсь представить тестовый платеж через PayPal песочницу я получаю этот новые ответ:

array(2) { ["header"]=> string(287) "HTTP/1.1 400 Bad Request Server: Apache-Coyote/1.1 PayPal-Debug-Id: b235ca4e7c1ed Content-Type: application/json Content-Length: 334 DC: origin1-api.sandbox.paypal.com Date: Thu, 10 Oct 2013 17:23:54 GMT Connection: close Set-Cookie: DC=origin1-api.sandbox.paypal.com; secure " ["body"]=> object(stdClass)#4 (5) { ["name"]=> string(16) "VALIDATION_ERROR" ["details"]=> array(1) { [0]=> object(stdClass)#5 (2) { ["field"]=> string(12) "transactions" ["issue"]=> string(95) "Item amount must add up to specified amount subtotal (or total if amount details not specified)" } } ["message"]=> string(29) "Invalid request - see details" ["information_link"]=> string(73) "https://developer.paypal.com/webapps/developer/docs/api/#VALIDATION_ERROR" ["debug_id"]=> string(13) "b235ca4e7c1ed" } }

Вот мой PayPal код:

class paypal { 
    private $access_token; 
    private $token_type; 

    /**

    *

    */ 
    public function __construct(){ 
     $postvals = "grant_type=client_credentials"; 
     $uri = PAYMENT_URI . "v1/oauth2/token"; 

     $auth_response = self::curl($uri, 'POST', $postvals, true); 
     $this->access_token = $auth_response['body']->access_token; 
     $this->token_type = $auth_response['body']->token_type; 
    } 

    /** 
    * cURL 
    * 
    * Handles GET/POST requests for auth requests 
    * @link http://php.net/manual/en/book.curl.php 
    */ 
    private function curl($url, $method = 'GET', $postvals = null, $auth = false){ 
     $ch = curl_init($url); 

     //if we are sending request to obtain bearer token 
     if ($auth){ 
      $headers = array("Accept: application/json", "Accept-Language: en_US"); 
      curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); 
      curl_setopt($ch, CURLOPT_USERPWD, CLIENT_ID . ":" .CLIENT_SECRET); 
      curl_setopt($ch, CURLOPT_SSLVERSION, 3); 
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
      curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); 
     //if we are sending request with the bearer token for protected resources 
     } else { 
      $headers = array("Content-Type:application/json", "Authorization:{$this->token_type} {$this->access_token}"); 
     } 

     $options = array(
      CURLOPT_HEADER => true, 
      CURLINFO_HEADER_OUT => true, 
      CURLOPT_HTTPHEADER => $headers, 
      CURLOPT_RETURNTRANSFER => true, 
      CURLOPT_VERBOSE => true, 
      CURLOPT_TIMEOUT => 10 
     ); 

     if ($method == 'POST'){ 
      $options[CURLOPT_POSTFIELDS] = $postvals; 
      $options[CURLOPT_CUSTOMREQUEST] = $method; 
     } 

     curl_setopt_array($ch, $options); 

     $response = curl_exec($ch); 
     $header = substr($response, 0, curl_getinfo($ch,CURLINFO_HEADER_SIZE)); 
     $body = json_decode(substr($response, curl_getinfo($ch,CURLINFO_HEADER_SIZE))); 
     curl_close($ch); 

     return array('header' => $header, 'body' => $body); 
    } 

    // Function for Processing Payment 
    function process_payment($request) { 
     $postvals = $request; 
     $uri = PAYMENT_URI . "v1/payments/payment"; 
     return $this->curl($uri, 'POST', $postvals); 
    } 
} 

Answer 1

Операция представляет собой массив, но вы передаете в объекте , Вы должны посылать

"сделки": [{ "количество": { ... } ]

вместо

https://developer.paypal.com/webapps/developer/docs/api/#create-a-payment см для более

Answer 2

Вы пытаетесь открыть сокет себя, так что вам нужно, чтобы добавить заголовок HTTP HOST себя

$header .= "Host: www.sandbox.paypal.com\r\n";
