26、自动爬取每日的天气，并定时把天气数据和穿衣提示发送到你的邮箱

自动爬取每日的天气，并定时把天气数据和穿衣提示发送到你的邮箱。

 

之所以选择这个相对朴实的爬虫项目，是因为天气每天都会有变化，那么在学完这一关之后，不出意外，你就可以在明早收到天气信息了。以此，亲身体验程序的作用。

 

你还可以把每日的天气和温馨的穿衣提示发送到你的恋人、家人、或朋友的邮箱里，这也是传递心意的一种方式。

 

总体上来说，可以把这个程序分成三个功能块：【爬虫】+【邮件】+【定时】

 

import requests
import time
import schedule
from selenium import webdriver
from bs4 import BeautifulSoup
import smtplib
from email.mime.text import MIMEText
from email.header import Header

def requests_fun():
    res = requests.get('http://www.weather.com.cn/weather1d/101010100.shtml')
    res.encoding='utf-8'
    soup = BeautifulSoup(res.text,'html.parser')
    tianqi  = soup.find('input',id='hidden_title')['value']
    chuanyi = soup.find('li',id='chuanyi').find('p').text
    return (tianqi,chuanyi)

def selenium_fun():
    driver = webdriver.Chrome()
    driver.get('http://www.weather.com.cn/weather1d/101010100.shtml')
    time.sleep(2)
    tianqi  = driver.find_element_by_id('hidden_title').get_attribute('value')
    chuanyi = driver.find_element_by_id('chuanyi').find_element_by_tag_name('p').text
    return str(tianqi,chuanyi)
    driver.close()

def mail_fun(tianqi,chuanyi,zhuti):
    mail_user = 'www1707@xxx.cn'
    mail_pwd  = 'yyy'
    receiver = 'user01@xxx.cn'
    subject = zhuti
    content = tianqi+'	'+chuanyi

    alimail = smtplib.SMTP()
    alimail.connect('smtp.qiye.aliyun.com',25)
    alimail.login(mail_user,mail_pwd)

    message = MIMEText(content,'plain','utf-8')
    message['Subject'] = Header(subject,'utf-8')
    message['From'] = Header(mail_user,'utf-8')
    message['To'] = Header(receiver,'utf-8')

    alimail.sendmail(mail_user,receiver,message.as_string())
    alimail.quit()

def main_fun():
    tianqi,chuanyi = requests_fun()
    zhuti = '天气早知道    '+time.ctime()
    mail_fun(tianqi,chuanyi,zhuti)
    print(zhuti)

#requests_fun()
#selenium_fun()
#mail_fun()
#main_fun()

schedule.every(10).seconds.do(main_fun)

while True:
    schedule.run_pending()
    time.sleep(1)
