python 爬取天氣並傳送郵箱

以中國天氣網為例（www.weather.com.cn）

主要的實現步驟有：

一、對中國天氣網進行爬取

二、通過郵箱傳送提醒

完成**：

import requests

from bs4 import beautifulsoup

import smtplib

from email.mime.text import mimetext

from email.header import header

#爬取資料

#獲得網頁
def get_html(url):
res = requests.get(url)
res.encoding = 'utf-8'
return res.text
#解析網頁
def parser_html(html):
soup = beautifulsoup(html,'html.parser')
#今天天氣情況
today = soup.find_all(class_ = 'sky skyid lv3 on')
for todaydata in today:
wea = todaydata.find(class_ = 'wea').text
tem = todaydata.find(class_ = 'tem').text
todaycontent = "天氣："+ wea + "溫度：" +tem
todaycontent = todaycontent.replace("\n","")
return todaycontent
#傳送資料
def sendemail(content):
# 第三方 smtp 服務
mail_host = "smtp.qq.com"  # 設定伺服器
mail_user = "***x"  # 使用者名稱
mail_pass = "******"  # 口令
sender = '******x'
receivers = ['******x']  # 接收郵件，可設定為你的qq郵箱或者其他郵箱
message = mimetext(content, 'plain', 'utf-8')
message['from'] = header("******", 'utf-8')
message['to'] = header("******x", 'utf-8')
subject = 'python今日天氣'
message['subject'] = header(subject, 'utf-8')
try:
smtpobj = smtplib.smtp()
smtpobj.connect(mail_host, 25)  # 25 為 smtp 埠號
smtpobj.login(mail_user, mail_pass)
smtpobj.sendmail(sender, receivers, message.as_string())
print("郵件傳送成功")
except smtplib.smtpexception:
print("error: 無法傳送郵件")
def main():
url = ''
html = get_html(url)
content = parser_html(html)
sendemail(content)
if __name__ == '__main__':
main()

1.擴大到多日天氣情況

在解析網頁的時候，訓練使用bs4和re的綜合訓練

def parser_html(html):

soup = beautifulsoup(html,'html.parser')
today = soup.find_all(class_ = 'sky skyid lv3 ')
for todaydata in today:
wea = todaydata.find(class_ = 'wea').text
tem = todaydata.find(class_ = 'tem').text
todaycontent = "天氣："+ wea + "溫度：" +tem
todaycontent = todaycontent.replace("\n","")
return todaycontent

win10環境下python指令碼定時執行

Python 爬取中國天氣網天氣並通過郵箱定時傳送

獲取天氣資訊指令碼如下,usr bin python3 coding utf 8 import re import requests from bs4 import beautifulsoup import io import sys r requests.get timeout 30 r.rais...

python 爬取天氣

準備工作做好了，接下來就是 了 用py爬天氣資訊，需要使用兩個模組，分別是urllib2 獲取資料 和json 解析資料 coding utf 8 import urllib2 import json from city import city cityname raw input 你想查哪個城市的...
