#31课课堂演示 把原来的city这个字典变成pkl文件 然后加载进来

import urllib.request
import json
import pickle
#建立城市字典 把pkl文件载入
pickle_file = open('city_data.pkl', 'rb')
city = pickle.load(pickle_file)


password=input('请输入城市:')

req = urllib.request.Request(url='http://m.weather.com.cn/data/'+name1+'.html',data=None,headers=header)


# 接着把File那句改成
File1 = urllib.request.urlopen(req)

weatherHTML= File1.read().decode('utf-8')#读入打开的url
weatherJSON = json.JSONDecoder().decode(weatherHTML)#创建json
weatherInfo = weatherJSON['weatherinfo']
