我在我的电脑里设置了webhook stripe 当我从stripe dashboard测试webhook时，我从stripe得到了成功的结果。我可以在预览中看到React。
但是，当我在浏览器上做这件事并点击相同的webhook url时，我的React却一无所获。
这是我用来让它工作的代码。

include('config.php');

function searchArrayValueByKey(array $array, $search) 
{
    foreach (new RecursiveIteratorIterator(new RecursiveArrayIterator($array)) as $key => $value) 
    {
        if ($search === $key)
        return $value;
    }
    return false;
}

require_once('vendor/autoload.php');

\Stripe\Stripe::setApiKey("Stripe Key");

// This function is leveraged to search through the JSON for specific values

$input = @file_get_contents("php://input");         
// this gets the POST data provided when the webhook pings this page
$event_json = json_decode($input, TRUE);    
// decode the JSON, and TRUE turns it into a multidimensional array

if(isset($type))
{
    $type = searchArrayValueByKey($event_json, 'customer.subscription.updated'); 
}
else
{
    $type = "";
}
// Check the type of event sent from Stripe.com - example "charge.succeeded"

switch ($type) 
{                                   
    // depending on the event fired by Stripe, do something different. 
    case "account.updated":
        // do something
        break;
    case "balance.available":
        // do something
        break;
    case "charge.captured":
        // do something

$myfile = fopen("auto_response.txt", "a+") or die("Unable to open file!");
file_put_contents('auto_response.txt', print_r($event_json,true),FILE_APPEND | LOCK_EX);
fclose($myfile);

==================
在这里写下答案 auto_response.txt 文件中，我可以将数据存储在文件中，但在数据库中存储数据时却一无所获。
所以有没有人有任何解决方案，因为我无法在mysql数据库中存储stripe响应。
