Email起到提醒作用,当爬虫过程中遇到异常或者服务器遇到问题,可以通过Email及时向自己报告。
发送邮件的协议是STMP,python内置对SMTP的支持,可以发送纯文本邮件、html邮件以及带附件的邮件。

SMTP协议

首先了解SMTP(简单邮件传输协议),邮件传送代理程序使用SMTP协议来发送电邮到接收者的邮件服务器。SMTP协议只能用来发送邮件,不能用来接收邮件,而大多数的邮件发送服务器都是使用SMTP协议。SMTP协议的默认TCP端口号是25。

发送邮件之前的配置:

 

上面说了是使用SMTP协议发送的邮件,所以需要先查看你的发件人邮箱是否有开启SMTP协议,如没有,则需要开启,我测试使用的是163.com的邮箱作为发信人邮箱,在设置中开启SMTP协议如下图所示。

构造一个简单的纯文本邮件

from email.mime.text import MIMEText
msg = MIMEText(‘Python爬虫运行异常,异常信息为遇到HTTP 403‘, ‘plain‘, ‘utf-8‘)
构造MIMEText对象时需要三个参数
邮件正文,‘Python爬虫运行异常,异常信息为遇到HTTP 403‘
MIMEL的subtype,‘plain‘表示纯文本
编码格式,‘utf-8‘

例子(1)

import smtplib
from email.header import Header
from email.mime.text import MIMEText
 
# 第三方 SMTP 服务
mail_host = "smtp.126.com"      # SMTP服务器
mail_user = "[email protected]"                  # 用户名
mail_pass = "******"               # 授权密码,非登录密码
 
sender = [email protected]    # 发件人邮箱(最好写全, 不然会失败)
receivers = [[email protected]]  # 接收邮件,可设置为你的QQ邮箱或者其他邮箱
 
content = Python爬虫运行异常
title = 测试  # 邮件主题
 
def sendEmail():
 
    message = MIMEText(content, plain, utf-8)  # 内容, 格式, 编码
    message[From] = "{}".format(sender)
    message[To] = ",".join(receivers)
    message[Subject] = title
 
    try:
        smtpObj = smtplib.SMTP_SSL(mail_host, 465)  # 启用SSL发信, 端口一般是465
        smtpObj.login(mail_user, mail_pass)  # 登录验证
        smtpObj.sendmail(sender, receivers, message.as_string())  # 发送
        print("mail has been send successfully.")
    except smtplib.SMTPException as e:
        print(e)
 
def send_email2(SMTP_host, from_account, from_passwd, to_account, subject, content):
    email_client = smtplib.SMTP(SMTP_host)
    email_client.login(from_account, from_passwd)
    # create msg
    msg = MIMEText(content, plain, utf-8)
    msg[Subject] = Header(subject, utf-8)  # subject
    msg[From] = from_account
    msg[To] = to_account
    email_client.sendmail(from_account, to_account, msg.as_string())
 
    email_client.quit()
 
if __name__ == __main__:
    sendEmail()

27         print("mail has been send successfully.")
28     except smtplib.SMTPException as e:
29         print(e)
30  
31 def send_email2(SMTP_host, from_account, from_passwd, to_account, subject, content):
32     email_client = smtplib.SMTP(SMTP_host)
33     email_client.login(from_account, from_passwd)
34     # create msg
35     msg = MIMEText(content, plain, utf-8)
36     msg[Subject] = Header(subject, utf-8)  # subject
37     msg[From] = from_account
38     msg[To] = to_account
39     email_client.sendmail(from_account, to_account, msg.as_string())
40  
41     email_client.quit()
42  
43 if __name__ == __main__:
44     sendEmail()
45     # receiver = ‘***‘
46     # send_email2(mail_host, mail_user, mail_pass, receiver, title, content)

终端显示发送成功。

1 wljdeMacBook-Pro:Desktop wlj$ python3 126.py
2 mail has been send successfully.
3 wljdeMacBook-Pro:Desktop wlj$ 

 

如果测试出现报错,请看网易邮箱给出的状态码及含义
