iOS 建立遠距推播 App (五) 推播測試 – 使用 php
1.伺服器檢查事項
(1) Web Server 需支援 HTTP/2

檢測方法一 : For Linux
$ curl --http2 -I https://www.google.com
不支援出現 :
curl : (1) Unsupported protocol

檢測方式二 : 使用 php
<?php
    echo $_SERVER[ "SERVER_PROTOCOL" ];

(2) PHP 版本需 5.5.24 版以上 php 的 curl 才有支援 HTTP/2

2. PHP 程式碼

    $device_token=""; //Device token
