Php 双请求只检查一个

我有一个webhook，我在某人商店的Shopify中使用它，但只有它使用信息上传到我的服务器

当店主点击fullfil项目时，订单将进入我的网站，但在某些情况下，订单只需点击一次就出现两次，我使用的是php和curl

这是我的php文件

<?php
//start a session
session_start();

//Webhook enviado por shopify
$webhookContent=        "";
$webhook=               fopen('php://input' , 'rb');
while (!feof($webhook)) {
    $webhookContent .=  fread($webhook, 4096);
}
fclose($webhook);
$data=      json_decode($webhookContent,true);

//guardar datos ordenes
$file = 'shipping_innata.txt';
$print = print_r($webhookContent, true);
file_put_contents($file, $print, FILE_APPEND | LOCK_EX);

如果我理解正确，您会想，为什么您会收到来自Shopify的多个请求，而不是一个请求

我最近也遇到了同样的问题，我认为这是Webhooks机制的一个特性，您必须处理它

以这篇文章为例：

底线。你应该预计Shopify会不止一次地攻击你的端点，你必须自己管理它，以避免重复实体和内容。

好吧，我看了这篇文章，如果我明白我需要对代码排队来解决问题，但现在我不明白我能做到这一点，我不知道我需要在代码的哪一部分尝试这一点。
