Python 通过微信控制实现app定位发送到个人服务器，再转发微信服务器接收位置信息。

考虑到女友的安全问题,就做了一个app实现定位和服务器实现转发的东西。刚学python,竟没想到用对象编程会更加方便,全程过程式开发,代码有点臃肿,就当学习下python吧.效果就是:在微信公众号中输入指定字符比如:”我要知道你的位置”,手机那端的位置就弹出来了.主要是讲一下思路:先是app实现定位,当微信发送消息时,消息从微信服务器转发到开发者服务器然后用socket发送指定消息来通知app,I need your location,app接收到消息之后再发送给开发服务器(app 开service实现后台全程运行),由于定位信息是经纬度,所以用了高德API,但是发现谷歌地球的定位是准的,可能和android内置的定位有关系吧,然后就转换了一下不同地图的经纬度,然后转成位置信息发送给微信服务器.

import socket

from flask import request

#实现通过微信控制手机app定位发送给服务器显示位置信息

loca = "welcome"
app = Flask(__name__)

#搭建web服务器通过socket发送消息给app索取定位信息，然后转发给微信服务器
@app.route("/wx_check",methods=["POST","GET"]) #这里用了一个Web框架   "/wx_check" 是你在微信中填的开发者服务器路径
def application():
    openID = request.args['openid'] # 微信发的,详见开发者文档
    soup = BeautifulSoup(request.data,"html.parser")
    content = soup.find("content") # content 是微信用户发的消息,可用来验证用户
    sock.send(b"getlocation") #  发送信息通知android
    global loca
    while True:  #手动阻塞
        if loca != "welcome":
            break
    back = loca
    loca = "welcome"

threading.Thread(target=start,args=()).start()

# 与app进行socket连接 接受定位信息 另外用到经纬度兼容转换API 和经纬度转位置API
def tcplink(sock,addr):
    try:

            if (l == null) {
                continue;
            }
            if (bestLocation == null || l.getAccuracy() < bestLocation.getAccuracy()) {

                bestLocation = l;
            }
        }
        return bestLocation;
    }


    String provider;

        Location location = getLastKnownLocation();

        Log.d("TAG", location.toString());
        if (location != null) {
            //获取当前位置，这里只用到了经纬度
            String string =location.getLongitude() + ","+ location.getLatitude();
