Question

我希望通过codeigniter中的php页面实现PayPals IPN。当我用沙箱测试我的代码时，我收不到Paypal的回复。尽管我的程序收到了原始消息，并且ipn模拟器声明“已发送IPN并且握手已经过验证”。任何人都可以指出以下代码中的错误：

if(array_key_exists('test_ipn', $_POST) && 1 == (int) $_POST['test_ipn'])
        $url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
    else
        $url = 'https://www.paypal.com/cgi-bin/webscr';

    // Set up request to PayPal
    $request = curl_init();
    curl_setopt_array($request, array
    (
        CURLOPT_URL => $url,
        CURLOPT_POST => TRUE,
        CURLOPT_POSTFIELDS => http_build_query(array_merge(array('cmd' => '_notify-validate'),$_POST)),
        CURLOPT_RETURNTRANSFER => TRUE,
        CURLOPT_HEADER => FALSE,
    ));

    // Execute request and get response and status code
    $response = curl_exec($request);
    $status   = curl_getinfo($request, CURLINFO_HTTP_CODE);

    // Close connection
    curl_close($request);

    $myfile = fopen("/var/www/vhosts/example.com/subdomains/apidev/httpdocs/application/controllers/test.txt", "w") or die("Unable to open file!");
    fwrite($myfile, json_encode($_POST)."\n\n");
    fwrite($myfile, $url."\n\n");
    //$response = file_get_contents($url);
    fwrite($myfile, "Response: ".$response."\n");
    fclose($myfile);
}

该文件的内容是：
