如何正確捕獲PaPal IPN數據

我想捕獲從PayPal發回IPN腳本的數據。在我的按鈕中，我確實設置了notify_url以及正確的值爲2（用於發佈數據）。我正在使用_xclick命令（cmd = _xclick）以及按鈕。如何正確捕獲PaPal IPN數據

在我的下面的代碼中，我定期寫入數據或流到錯誤日誌來捕捉正在發生的事情。但似乎PayPal正在推動IPN，但沒有數據被捕獲（或至少是正確的）。

這裏是我的整個IPN腳本的時刻：

 // STEP 1: read POST data 

      // Reading POSTed data directly from $_POST causes serialization issues with array data in the POST. 
      // Instead, read raw POST data from the input stream. 

      $raw_post_data = file_get_contents('php://input'); 


      error_log("Got " . $raw_post_data . " when processing IPN data"); 
      error_log("-------------------\n"); 

      $raw_post_array = explode('&', $raw_post_data); 
      $myPost = array(); 
      foreach ($raw_post_array as $keyval) { 
       $keyval = explode ('=', $keyval); 
       if (count($keyval) == 2) 
       $myPost[$keyval[0]] = urldecode($keyval[1]); 
      } 


      // read the IPN message sent from PayPal and prepend 'cmd=_notify-validate' 
      $req = 'cmd=_notify-validate'; 
      if(function_exists('get_magic_quotes_gpc')) { 
       $get_magic_quotes_exists = true; 
      } 


      foreach ($myPost as $key => $value) {   
       if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) { 
        $value = urlencode(stripslashes($value)); 
       } else { 
        $value = urlencode($value); 
       } 
       $req .= "&$key=$value"; 
      } 


      error_log("Got response: " . $req . " when processing IPN data"); 
      error_log("-------------------\n"); 

      // STEP 2: POST IPN data back to PayPal to validate 

      $ch = curl_init('https://www.paypal.com/cgi-bin/webscr'); 
      curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); 
      curl_setopt($ch, CURLOPT_POST, 1); 
      curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); 
      curl_setopt($ch, CURLOPT_POSTFIELDS, $req); 
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1); 
      curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); 
      curl_setopt($ch, CURLOPT_FORBID_REUSE, 1); 
      curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close')); 
      $res = curl_exec($ch); 

      error_log("Got response: " . $res . " when processing IPN VALIDATE"); 
      error_log("-------------------\n"); 



      if(!($res)) { 
       error_log("Got " . curl_error($ch) . " when processing IPN Validation"); 
       curl_close($ch); 
       exit; 
      } 

      curl_close($ch); 


      error_log("Got response: " . $res . " when processing IPN data"); 
      error_log("-------------------\n"); 

      // STEP 3: Inspect IPN validation result and act accordingly 

      if (strcmp (trim($res), "VERIFIED") == 0) { 
       // The IPN is verified, process it: 
       // check whether the payment_status is Completed 
       // check that txn_id has not been previously processed 
       // check that receiver_email is your Primary PayPal email 
       // check that payment_amount/payment_currency are correct 
       // process the notification 

       // assign posted variables to local variables 
       $item_name = $_POST['item_name']; 
       $item_number = $_POST['item_number']; 
       $payment_status = $_POST['payment_status']; 
       $payment_amount = $_POST['mc_gross']; 
       $payment_currency = $_POST['mc_currency']; 
       $txn_id = $_POST['txn_id']; 
       $receiver_email = $_POST['receiver_email']; 
       $payer_email = $_POST['payer_email']; 

       // IPN message values depend upon the type of notification sent. 
       // To loop through the &_POST array and print the NV pairs to the screen: 

       foreach($_POST as $key => $value) { 
        //echo $key." = ". $value."<br>"; 
        error_log($key." = ". $value."\n"); 
       } 
      } else if (strcmp ($res, "INVALID") == 0) { 
       // IPN invalid, log for manual investigation 
       $t = "The response from IPN was: <b>" .$res ."</b>"; 
       error_log($t."\n"); 
      }

結果捕捉到的數據是，IPN無效響應。

我不知道我在這裏錯過了什麼。看起來像file_get_contents（'php：// input'）根本沒有捕獲任何數據。有沒有更好的方法來捕獲輸入數據，而不是使用file_get_contents（'php：// input'）或使用$ _POST變量？

感謝任何其他見解。謝謝。

嘗試通過下面的代碼改變第1步：

// Prepare data that will sent to Paypal for verification 
$req = "cmd=_notify-validate"; 
foreach ($_POST as $key => $value) { 
    $value = urlencode(stripslashes($value)); 
    $req .= "&$key=$value"; 
    $content = "&$key=$value"; 
}

注意：您可以使用PayPal的sandbox website for developer來測試你的IPN聽者那麼你應該

更改線路

$ch = curl_init('https://www.paypal.com/cgi-bin/webscr');

$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');

希望這會hepl，
