通篇分爲三大塊：服務器、藍牙鎖、APP
先說服務器：
使用的是TP5、workman框架使用composer安裝的
安裝wm可直接參考TP5的官方手冊，講解的很細緻https://www.kancloud.cn/manual/thinkphp5/235128
Server.php文件
這裏我對Server類進行了一些改動
爲了加入定時器的功能
新增加了一個$inner_text_worker = new Worker('Text://0.0.0.0:5678');服務協議，用作APP端發送開鎖指令&告知藍牙鎖進行開關鎖；
構造函數裏面重寫了$this->worker->onWorkerStart函數，這樣的話Worker控制器裏面的onWorkerStart函數將失去作用，如果不在這裏重寫，去Worker控制器裏面的onWorkerStart函數加定時器將不起作用，因爲Server構造函數裏面已經運行了（Worker::runAll();）所有協議。
由於這裏進行了AES的加、解密，參考的時候可以忽略加解密容易瀏覽。
