需求:
1、获取前十条科技要闻
2、通过邮件发送给指定收件人
3、定时发送
1、获取要闻,选的是新浪科技网https://tech.sina.com.cn/,爬取前十名要闻
import requests from requests import exceptions from urllib.request import urlopen from bs4 import BeautifulSoup import re # 获取前十条科技新闻 def get_tech_news(): # 获取网页文本 resp = urlopen(‘https://tech.sina.com.cn/‘) # 使用爬虫工具BeautifulSoup查找需要的文本内容 soup = BeautifulSoup(resp, ‘html.parser‘) news = soup.find(‘ul‘, class_=‘rank-con‘) news_list = [] for new in news: if len(new.string) > 5: news_list.append(new.string.replace(‘ ‘, ‘,‘)) # 组装邮件文本,<br>换行 news_contents = f‘‘‘ 今日科技要闻<br> 1、{news_list[0]}<br> 2、{news_list[1]}<br> 3、{news_list[2]}<br> 4、{news_list[3]}<br> 5、{news_list[4]}<br> 6、{news_list[5]}<br> 7、{news_list[6]}<br> 8、{news_list[7]}<br> 9、{news_list[8]}<br> 10、{news_list[9]}<br> 详情,请进入https://tech.sina.com.cn 查看 ‘‘‘.replace(‘\t‘, ‘‘) print(news_contents) send_email("今日科技要闻", news_contents)
2、定义发送邮件函数,跟上次一样,同级目录需要config.yml配置文件
# config.yml配置文件 email: sender: ‘mikasama007@163.com‘ receiver: ‘mikasama007@163.com‘ smtpserver: ‘smtp.163.com‘ username: ‘mikasama007‘ password: ‘邮箱密码‘
import time import yaml import smtplib import sys from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.mime.base import MIMEBase from email.header import Header def get_conf(): with open ("config.yml", "r", encoding=‘utf-8‘) as f: cfg = f.read() dic = yaml.load(cfg) # print(type(dic)) # print(dic) sender = dic[‘email‘][‘sender‘] receiver = dic[‘email‘][‘receiver‘] smtpserver = dic[‘email‘][‘smtpserver‘] username = dic[‘email‘][‘username‘] password = dic[‘email‘][‘password‘] # print(sender, receiver, smtpserver, username, password) return sender, receiver, smtpserver, username, password def send_email(title, text): today = time.strftime(‘%Y.%m.%d‘,time.localtime(time.time())) sender, receiver, smtpserver, username, password = get_conf() # subject为邮件主题 text为邮件正文 subject = "{}:{}".format(title, today) msg = MIMEText(text, ‘html‘, ‘utf-8‘) msg[‘Subject‘] = subject msg[‘From‘] = sender msg[‘To‘] = "".join(receiver) # smtp = smtplib.SMTP() # smtp.connect(smtpserver) # 变量名不能为stmp,改为server # windows上端口为25,linux上使用SMTP_SSL # server = smtplib.SMTP(smtpserver, 25) # https://blog.csdn.net/zekdot/article/details/81013176 server = smtplib.SMTP_SSL(smtpserver, 465) server.set_debuglevel(0) server.login(username, password) server.sendmail(sender, receiver, msg.as_string()) server.quit()
3、引入schedule库,定时发送邮件
import schedule # 每天早上8点发送邮件通知 schedule.every().day.at("08:00").do(do_all_get_tech_news) # 确保schedule一直运行 while True: schedule.run_pending() time.sleep(1)
4、丢服务器上去
运行python send_news.py
居然发不了邮件?换个地方就不行?
将登陆模式改为SSL即可:
server = smtplib.SMTP_SSL(smtpserver, 465)
修改后,可以正常发送邮件,cool!
但是这样可不行,ssh连接关闭,程序肯定会退出的,我们需要后台运行:
nohup python send_news.py &
查看下:
# root @ www in /home/cool_things/send_news [23:06:35] C:1 $ nohup python send_news.py & [1] 24713 # root @ www in /home/cool_things/send_news [23:06:45] $ nohup: ignoring input and appending output to ‘nohup.out’ # root @ www in /home/cool_things/send_news [23:06:50] $ ps -ef | grep python root 724 1 0 Apr01 ? 00:25:52 /usr/bin/python -Es /usr/sbin/tuned -l -P root 10357 1 0 Apr01 ? 00:03:20 /usr/bin/python -Es /usr/sbin/firewalld root 23391 1 0 Sep01 ? 00:10:10 python send_msg_to_wx.py root 24713 21231 1 23:06 pts/1 00:00:00 python send_news.py # root @ www in /home/cool_things/send_news [23:06:58] $ ps -ef | grep send_news root 24713 21231 0 23:06 pts/1 00:00:00 python send_news.py
搞定,程序已经在后台运行,从明天开始,三爷每天早上8点就能收到每日要闻邮件了。
