请务必每天早上8点将前十条科技要闻发给三爷

台风已登录，大家注意安全。

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 requestsfrom requests import exceptionsfrom urllib.request import urlopenfrom bs4 import BeautifulSoupimport 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，

换行 news_contents = f''' 今日科技要闻

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

import timeimport yamlimport smtplibimport sysfrom email.mime.multipart import MIMEMultipartfrom email.mime.text import MIMETextfrom email.mime.base import MIMEBasefrom email.header import Headerdef 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, passworddef 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 pythonroot 724 1 0 Apr01 ? 00:25:52 /usr/bin/python -Es /usr/sbin/tuned -l -Proot 10357 1 0 Apr01 ? 00:03:20 /usr/bin/python -Es /usr/sbin/firewalldroot 23391 1 0 Sep01 ? 00:10:10 python send_msg_to_wx.pyroot 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_newsroot 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。
