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
import threading
import os
import requests
from flask import Flask
from flask import request
from bs4 import BeautifulSoup
import json
global sock
#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"
  return """
  <xml> 
  <ToUserName>%s</ToUserName> 
  <FromUserName>qqmsssssssss</FromUserName>
  <CreateTime>12345678</CreateTime> 
  <MsgType>text</MsgType> 
  <Content>%s</Content> 
  </xml>"""%(openID,back)
def start():
  app.run('0.0.0.0',80)
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:
    print('Accept new connection from %s:%s...' % addr)
    while True:
      sock.setblocking(True)
      data = sock.recv(1024)
      location = data.decode('utf-8')
      print("client:"+location)
      # 以下进行经纬度 地图信息的转换 loca为app所在地址接上面的 堵塞
      if location != "":
        global loca
        print(location)
        lis = location.split(",")
        location = "%s,%s"%(lis[1],lis[0])
        print(location)
        xml = requests.get("http://api.gpsspg.com/convert/coord/?oid=xxxx&key=xxxxxxxxxxxxxxxxxx&from=0&to=3&latlng=%s&output=xml"%location)
        soup = BeautifulSoup(xml.text,"html.parser")
        print(soup.text)
        lat= soup.find("lat").string
        lng= soup.find("lng").string
        location = "%s,%s"%(lng,lat)
        print("after"+location)
        a = requests.get("http://restapi.amap.com/v3/geocode/regeo?key=xxxxxxxxxxxxxxxxx&location="+location)
        loca = a.text
        obj = json.loads(loca)
        loca = obj["regeocode"]["formatted_address"]
      else:
        print("socket is close,waiting new accept")
        sock.close()
        break
  except Exception as e:
    location = "raise error"
  finally:
    pass

try:
  s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
  s.bind(('0.0.0.0',9999))
  s.listen(10)
  print('waiting to connect')
  while True:
    sock,addr = s.accept()  #等待app来连接
    t = threading.Thread(target=tcplink,args=(sock,addr))
    t.start()
finally:
  print("ending")

以下是android端代码:

# 获取定位,其实就是获取经纬度
private Location getLastKnownLocation() {
    LocationManager mLocationManager = (LocationManager)getApplicationContext().getSystemService(LOCATION_SERVICE);
    List<String> providers = mLocationManager.getProviders(true);
    Location bestLocation = null;
    for (String provider : providers) {
      Location l = mLocationManager.getLastKnownLocation(provider);
      if (l == null) {
        continue;
      }
      if (bestLocation == null || l.getAccuracy() < bestLocation.getAccuracy()) {
        // Found best last known location: %s", l);
        bestLocation = l;
      }
    }
    return bestLocation;
  }

  String provider;
  public void GetLocation(){
    LocationManager mLocationManager;
    Location location = getLastKnownLocation();

//    Log.d("TAG", provider.toString());
    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();
      try {
        OutputStream outputStream = socket.getOutputStream();
        PrintWriter writer = new PrintWriter(outputStream);
        writer.write(string);
        writer.flush();
//       writer.close();
//       socket.shutdownOutput();
      } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      }
    }
  }
  @SuppressLint("ShowToast") public void Connect(){
    try {
      socket = new Socket();
      socket.connect(new InetSocketAddress("xxx.xxx.xxx.xxx",9999));
      while (true) {
        Log.d("TAG", socket.isConnected()+"");
        InputStream stream = socket.getInputStream(); 
        byte[] b = new byte[11];
        stream.read(b);
        String sb = new String(b);
        if(sb.equalsIgnoreCase("getlocation")){
          GetLocation();
        }else
        {
          OutputStream outoStream = socket.getOutputStream();
          outoStream.write("error code".getBytes());
          socket.shutdownOutput();
        }
      }
    } catch (IOException e) {
      // TODO Auto-generated catch block
      Log.d("TAG", "error");
      e.printStackTrace();
    }
  }
