考慮到女友的安全問題,就做了一個app實現定位和伺服器實現轉發的東西。剛學python,竟沒想到用物件程式設計會更加方便,全程過程式開發,程式碼有點臃腫,就當學習下python吧.效果就是:在微信公眾號中輸入指定字元比如:”我要知道你的位置”,手機那端的位置就彈出來了.主要是講一下思路:先是app實現定位,當微信傳送訊息時,訊息從微信伺服器轉發到開發者伺服器然後用socket傳送指定訊息來通知app,I need your location,app接收到訊息之後再發送給開發伺服器(app 開service實現後臺全程執行),由於定位資訊是經緯度,所以用了高德API,但是發現谷歌地球的定位是準的,可能和android內建的定位有關係吧,然後就轉換了一下不同地圖的經緯度,然後轉成位置資訊傳送給微信伺服器.

#實現通過微信控制手機app定位傳送給伺服器顯示位置資訊

loca = "welcome"

#搭建web伺服器通過socket傳送訊息給app索取定位資訊，然後轉發給微信伺服器
@app.route("/wx_check",methods=["POST","GET"]) #這裡用了一個Web框架   "/wx_check" 是你在微信中填的開發者伺服器路徑
