1.利用聚合网站的接口，获取深圳的天气预报

登录https://www.juhe.cn/,申请天气api接口，然后利用python去调用api获取近5日天气数据,并命名为weather.py

# coding=utf-8
import requestsclass Weather_get:def __init__(self, city, key):self.city = cityself.key = keydef request(self):url = "http://apis.juhe.cn/simpleWeather/query?city=%s&key=%s" % (self.city, self.key)try:response = requests.get(url, timeout=10)return response.json()except Exception as e:print('页面访问超时......', e)def get_data(self):data = self.request()if data['reason'] == '查询成功!':try:for weather in data['result']['future']:data_weather = {'date': weather['date'], 'temperature':weather['temperature'], 'weather': weather['weather']}yield data_weatherexcept Exception as e:print(e)else:print(data['reason'])

2.发送天气数据到对应邮箱

# coding=utf-8
from Class.weather import Weather_get
import smtplib
from email.mime.text import MIMEText
import jsonclass SendWeather:def get_weather(self):city = '深圳'  # 输入自己的城市key = "写自己的key"  # 申请之后会得到一个key，datas = Weather_get(city, key).get_data()  # 天气数据，是一个生成器weathers = []for w in datas:# 得到一个列表，包含5个字典对象，[{'date': '2020-06-18', 'temperature': '27/32℃', 'weather': '多云'}。。。]weathers.append(w)return weathersdef send_weather(self):content = self.weather_format()email_host = 'smtp.163.com'  # 邮箱地址email_user = 'lovepachong@163.com'  # 发送者账号email_pwd = 'xxxxxxxxx'  # 发送者的密码,163邮箱是一串随机码，并不是你的登录密码maillist = '545186061@qq.com,lovepachong@163.com'   # 收件人邮箱，多个账号的话，用逗号隔开sender = email_usermsg = MIMEText(content)  # 邮件内容msg['Subject'] = '小阿黑深圳天气提醒'  # 邮件主题msg['From'] = sender  # 发送者账号msg['To'] = maillist  # 接收者账号列表try:smtp = smtplib.SMTP(email_host, port=25)  # 连接邮箱，传入邮箱地址，和端口号，smtp的端口号是25smtp.login(email_user, email_pwd)  # 发送者的邮箱账号，密码smtp.sendmail(sender, msg['To'].split(','), msg.as_string())  # 参数分别是发送者，接收者，第三个是把上面的发送邮件的内容变成字符串smtp.quit()  # 发送完毕后退出smtpprint('email send success.')except smtplib.SMTPException as e:print('发送失败....', e)# 将天气数据进行处理，使保存的数据更加美观def weather_format(self):weathers = self.get_weather()w0 = json.dumps(weathers[0], ensure_ascii=False)  # json数据转为字符串，需要使用dumps转储w1 = json.dumps(weathers[1], ensure_ascii=False)w2 = json.dumps(weathers[2], ensure_ascii=False)w3 = json.dumps(weathers[3], ensure_ascii=False)w4 = json.dumps(weathers[4], ensure_ascii=False)content = '''%s\n%s\n%s\n%s\n%s\n''' % (w0, w1, w2, w3, w4)return contentif __name__ == '__main__':s = SendWeather()s.send_weather()
