参考用Python玩转微信（一），做了一些修改

Geopy模块几乎用不了，使用百度AK获取指定地区的经纬度，但是百度热图实例打不开，最终用高德地图热图实例实现。。。
注意json还是要用json库的dumps实现，自己瞎编辑的json格式无法识别，估计无法正确读入.js文件的json数据吧。。。。

# coding=gbk
import itchat
import requests
import json

# 获取微信好友城市列表，去掉未设置城市的好友的空串''
itchat.auto_login()
friends = itchat.get_friends(update=True)[:]

citys = []
for friend in friends:
    if friend['City'] != '':
        citys.append(friend['City'])


# 申请百度的AK，取得微信好友的经纬度
def geocode(address):
    url = 'http://api.map.baidu.com/geocoder/v2/?address=' \
          + address + '&output=json&ak=7LpPYrfuXuGdDmRELo2TSsLenCKtvdMi'
    response = requests.get(url)
    data = response.json()
    # 返回经纬度字典
    return data['result']['location']


# 将经纬度，添加"value"=1,作为热点保存到列表中
points = []
for city in citys:
    location = geocode(city)
    location['value'] = 1
    points.append(location)

# 将字典的列表转成json格式，赋值到wechat_heatmap.html的heatmapData.js文件中: var heatmapData = ...
points_json = json.dumps(points)
print(points_json)

# 最后在wechat_heatmap.html复制高德热力图实例源码 https://lbs.amap.com/api/loca-api/demos/loca_heatmap/loca_heatmap_3d/
# wechat_heatmap.html中添加高德地图申请的web端Key
# <script src="//webapi.amap.com/loca?v=1.2.0&key=8e801b290ca8dae42e46e36c72f2bfa3"></script>
# <script src="heatmapData.js"></script>
# .js和.html文件在同级，打开html文件即可查看热力图
