手动解析一下

定义获取数据的函数

把上面的代码整合成下面两个函数

weather_forecast 返回今明两天天气预报
weather_now 返回实时天气

1. 预报天气

import requests
import json

key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

def weather_forecast(loc):
    
    url = 'https://free-api.heweather.net/s6/weather/forecast?location={}&key={}'.format(loc,key)
    res = requests.get(url)

    data = json.loads(res.text)
    data_str = json.dumps(data, ensure_ascii=False, indent=4, separators=(',', ':'))

    weather_data = data["HeWeather6"][0]
    location = weather_data["basic"]["location"]
    admin_area = weather_data["basic"]["admin_area"]
    cnty = weather_data["basic"]["cnty"]
    time = weather_data["update"]["loc"]
    forecast = weather_data["daily_forecast"]

    day_text = ["今天","明天","后天"]
    message = "地区：{}-{}-{}\n".format(cnty,admin_area,location)
    message += "时间：{}\n".format(time)
    message += '\n'.join(["{}({})，日间天气{}，夜间天气{}，相对湿度{}%，最高气温{}度，最低气温{}度，风向{}，风力{}级，能见度{}公里。"\
                         .format(day_text[i],
                                forecast[i]["date"],
                                forecast[i]["cond_txt_d"],
                                forecast[i]["cond_txt_n"],
                                forecast[i]["hum"],
                                forecast[i]["tmp_max"],
                                forecast[i]["tmp_min"],
                                forecast[i]["wind_dir"],forecast[0]["wind_sc"],forecast[0]["vis"])for i in range(2)])
    return message

2. 实时天气

def weather_now(loc):
    url = 'https://free-api.heweather.net/s6/weather/now?location={}&key={}'.format(loc, key)
    res = requests.get(url)

    data = json.loads(res.text)
    data_str = json.dumps(data, ensure_ascii=False, indent=4, separators=(',', ':'))
    print(data_str)
    weather_data = data["HeWeather6"][0]
    location = weather_data["basic"]["location"]
    admin_area = weather_data["basic"]["admin_area"]
    cnty = weather_data["basic"]["cnty"]
    time = weather_data["update"]["loc"]
    now = weather_data["now"]

    message = "[自动回复-实时天气]\n"
    message += "地区：{}-{}-{}\n".format(cnty, admin_area, location)
    message += "时间：{}\n".format(time)
    message += "天气{}，温度{}度，体感温度{}度，相对湿度{}%，风向{}，风力{}级，能见度{}公里。" \
        .format(now["cond_txt"],
                now["tmp"],
                now["fl"],
                now["hum"],
                now["wind_dir"],
                now["wind_sc"],
                now["vis"])
    return message

微信自动发送消息

使用 itchat 给好友发送消息

这里搜索指定昵称（RemarkName）的好友，当确定搜索结果为1人，且昵称完全匹配的时候再发送！

RemarkName = 'csm'  # 搜索昵称
result = itchat.search_friends(nickname)

if len(result)==1 and nickname == result[0]["RemarkName"]: # 
    target = name[0]["UserName"]
    message_concent = weather_forecast(loc='杭州')
    itchat.send(message_concent,target)

这可以用于定时给某人发送消息

自动回复消息

当然还可以做成一个被动查询天气的工具，只要聊天中出现地名，就返回查询结果在这里插入图片描述

# 全局变量，控制开关
global on
on = True

CSV_FILE_PATH = './china-city-list.csv'
df = pd.read_csv(CSV_FILE_PATH, skiprows=1)
city_set = set(df["City_CN"])

# 事件驱动函数
@itchat.msg_register(itchat.content.TEXT, isFriendChat=True)
def text_reply(msg):
    global on

    # json_str = json.dumps(msg, ensure_ascii=False, indent=4, separators=(',', ':'))
    # print(json_str)

    # 发给文件助手时，相当于发给自己
    if msg.toUserName == "filehelper":
        msg.fromUserName = msg.toUserName

    # 打开、关闭自动回复
    if msg.toUserName == msg.fromUserName:
        if msg.text == "on":
            on = True
        elif msg.text == "off":
            on = False
    print("Auto-Reply: ", on)

    if on:
        time_str = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(msg.createTime))
        msg_str = "Time: {}\nFrom: {} \nTo  : {}\nCont: {}".format(time_str, msg.fromUserName, msg.toUserName, msg.content)
        print(msg_str)

        loc_list = []
        for w in jieba.cut(msg.content, cut_all=False):
            if w in city_set:
                loc_list.append(w)

        for loc in loc_list:
            m = weather_now(loc)
            itchat.send_msg(m, msg.fromUserName)


# 二维码登陆
itchat.auto_login(hotReload=True)
itchat.run()
