什么是 Webhook？
Webhook 就是用户通过自定义回调函数的方式来改变 Web 应用的一种行为。通过 Webhook ，您可以自定义一些行为通知到指定的 URL 去。 当请求数据完成， Webhook 会通过您设置的 URL 将对应数据响应给您。
Webhook V2
当查询状态有更新，且触发了你在设置中的状态更新提醒时，系统会做出一个POST请求发送到你在webhook页面自定义的回调url上。其中，POST主体包含了以下数据的JSON字符串。
目前，我们支持HTTP和HTTPS链接来确保启用SSL链接时网站的安全性。但是请记住，此时你的终端在互联网上将是完全开放的。
签名验证:
为了确保消息的来源身份是 trackingmore, 你可以选择对 POST 数据的来源进行安全认证. ( 不验证, 直接解析 POST 的数据也可以 ).安全认证的方法如下:
1. 解析出 POST 数据中的 timeStr 和 signature 这两个参数。
2. 使用你的trackingmore用户邮箱(密钥) 和 timeStr(明文) 生成签名 signature, 与 POST 数据中的 signature 进行校验 ( 签名算法: PHP：SHA256、JAVA：HmacSHA256)
PHP 示例代码:
function verify($timeStr,$useremail,$signature){
$hash="sha256";
$result=hash_hmac($hash,$timeStr,$useremail);
return strcmp($result,$signature)==0?1:0;
}How to use:
Step 1:你应该先在你的用户后台设置你的webhook url 和需要提醒的状态！ my.trackingmore.com/webhook_setting.php
Step 2:当我们服务器检测到你的单号更新且满足你的设置的时候，我们就会将更新后的数据推送到你设置的webhook url路径上。所以你需要预先在这个webhook url写好你自己的程序，对接收到的webhook数据进行任意操作。当我们推送过来的时候你的程序就会执行一次。
Step 3:如何获取webhook推送过来的数据，在php中只需要$inputJSON = file_get_contents("php://input"); $inputJSON就是我们推送过来的数据。如下是我们获取数据并写入文件的例子，当然你也可以将它存入数据库。
