Python:获取中国城市的天气预报json数据（B）

上一篇（https://zhangphil.blog.youkuaiyun.com/article/details/110357488）已经知道如何获取某个城市的天气预报城市编码，接下来可以通过天气预报接开获取天气json数据：

import pandas as pd
import json
import urllib


def get_weather_data(city_code):
    url = f'http://www.weather.com.cn/data/cityinfo/{city_code}.html'
    response = urllib.request.urlopen(url)
    content = response.read().decode('utf-8')
    return content


def search_city_code(city_name):
    city_code = '-1'

    df = pd.read_json('city_code.json')
    for row in df.values:
        row_data = row[0]
        city_data = row_data['市']
        for cd in city_data:
            # print(cd['市名'], cd['编码'])
            if (city_name == cd['市名'] or cd['市名'] in city_name):
                city_code = cd['编码']
                break

    return city_code


if __name__ == '__main__':
    city_name_list = ['北京', '上海', '广州', '深圳', '成都']  # 获取以上五个城市天气数据
    for cn in city_name_list:
        city_code = search_city_code(cn)
        weather_data = get_weather_data(city_code)
        json_data = json.loads(weather_data)
        print(json_data)
        temp1 = json_data['weatherinfo']['temp1'].strip('℃')  # 清洗数据，保留纯粹的数字
        print(cn, temp1)
