Python—爬虫之实操项目：将爬取的数据定时发送邮件‘
import requests #导入requests库
import smtplib #发送邮件使用
import schedule #定时发送
import time #时间模块
from bs4 import BeautifulSoup #导入BeautifulSoup
from email.mime.text import MIMEText #构建邮件内容
from email.header import Header #构建邮件头
#输入隐私信息
mailbox = input('请输入你的邮箱：')
password = input('请输入你的密码：')
receiver = input('请输入收件人的邮箱')
#爬取数据
def foods():
url = 'http://www.xiachufang.com/explore/'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.116 Safari/537.36'}
res = requests.get(url,headers = headers)
soup = BeautifulSoup(res.text,'html.parser')
list_foods = soup.find_all('div',class_ = 'info pure-u')
list_all = []
for food in list_foods:
title = food.find('a').text.strip()
herf = 'http://www.xiachufang.com' + food.find('a')['href']
pei_l = food.find('p',class_ = 'ing ellipsis').text.strip()
list_all.append([title,herf,pei_l])
return list_all
#发送邮件
def send_email(list_all):
global mailbox,password,receiver #设置为全局变量
mailhost = 'smtp.qq.com'
qqmail = smtplib.SMTP()
qqmail.connect(mailhost,46)
qqmail.login(mailbox,password)
content = list_all
massage = MIMEText(content,'plain','utf-8')
subject = '本周最受欢迎菜谱'
message['subject'] = Header(subject,'utf-8')
try:
qqmail.sendmail(mailbox,receiver,message.as_string())
print('邮件发送成功')
except:
print('邮件发送失败')
qqmail.quit()
#定时执行任务
def job():
print('开始执行')
list_all = foods() #调取爬取数据的函数并将结果赋值给新变量
send_email(list_all) #调取发送邮件的函数，并传入邮件内容
print('任务完成')
schedule.every().day.at("10:30").do(job) #设定每天10:30执行任务
while True: #当符合条件的情况下就执行任务
schedule.run_pending()
time.sleep(2)
Traceback (most recent call last):

qqmail.connect(mailhost,465)
File "D:\py\lib\smtplib.py", line 338, in connect

smtplib.SMTPServerDisconnected: Connection unexpectedly closed
总是出现这个问题，请问该怎么解决
