我正在使用Codeigniter paypal_lib測試我的購物車結帳。我從沙盒消息中獲得的結果：「VERIFIED」以及函數「validate_ipn」返回true。但是我在這裏遇到的麻煩是我的日誌文件和訂單數據包含從PayPal不時相同的數據。如何解決在一個交易中接收多個IPN消息（相同內容）
下面是我的IPN驗證：
function validate_ipn(){
$url_parsed = parse_url($this->paypal_url);
$post_string="cmd=_notify-validate";
if ($this->CI->input->post())
{
foreach ($this->CI->input->post() as $field=>$value)
{
$this->ipn_data[$field] = $value;
$post_string .= '&' . $field.'='.urlencode(stripslashes($value));
}
}
//$fp = fsockopen($url_parsed['host'],"80",$err_num,$err_str,30);
$fp = fsockopen('ssl://www.sandbox.paypal.com', 443, $err_num, $err_str, 30);
if(!$fp)
{
$this->last_error = "fsockopen error no. $errnum: $errstr";
$this->log_ipn_results(false);
return false;
}
else
{
fputs($fp, "POST $url_parsed[path] HTTP/1.1\r\n");
fputs($fp, "Host: $url_parsed[host]\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ".strlen($post_string)."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $post_string . "\r\n\r\n");
// loop through the response from the server and append to variable
while(!feof($fp))
$this->ipn_response .= fgets($fp, 1024);
fclose($fp); // close connection
}
if (eregi("VERIFIED",$this->ipn_response))
{
// Valid IPN transaction.
$this->log_ipn_results(true);
return true;
}
else
{
$this->last_error = 'IPN Validation Failed.';
$this->log_ipn_results(false);
return false;
}
}
這是我在我的日誌（沒有什麼不同）得到。所以許多消息是這樣的：

我現在有完全相同的問題 – mclaassen 2013-07-24 01:34:58
很奇怪 - 你如何將IPN網址傳遞給貝寶？ IIRC，您可以將其設置在您的帳戶中，並且可以在付款過程中傳遞它。不知道兩者是否會造成兩個通知？另外，不要打折貝寶的錯誤。我遇到了一些問題，需要與員工長時間打電話，結果導致他們採取了一些行動來解決問題。檢查您的出站流程和帳戶，然後我建議您與他們聯繫。關於同一件事的兩個通知，相隔2分鐘似乎......很奇怪。間歇？ – 2013-11-08 05:12:56
