修改說明

[緣由]

最一開始的設計,就是工研院的 v1.0 API 版本,以工研院的網址當 Server,網頁系統當 client,已經全都寫好了這種方式的設計。後來因為討論到工研院的系統,每家店會安裝一套,且會在內部網路,就沒有對外可連線的 API URL 網址可以當 Server 溝通了,因此決定改成彼此用 websocket 溝通。

[遇到的困難]

再來網頁系統這邊花了相當多的時間去改版 websocket 溝通方式,也終於全部都改好了,讓原本 v1.0 API 的每項呼叫都可以使用,完全移植過來 websocket 版本,也是以工研院的系統端當成存放攝影機/網格設定的Server,網頁這邊只當做client端顯示與送出設定資料。 但實測後, websocket 光要一直保持著連線,似乎就是個大問題了..光要測試就很難找到一直連線著的狀態,結果網頁這邊所有的頁面呈現時,都會先去 websocket 要資料,變成一直 timeout 整個網頁都很奇怪,設定的出現與否也時有時無。

舉手偵測系統串接文件

建立 HandRaisingSystem 和 Camera

輸入以下指令,建立一台舉手系統和三台攝影機:
