python实现收邮件判断模块poplib,email

一、代码

# 输入邮件地址, 口令和POP3服务器地址:
import datetime
import email
import poplib
import email.policy
from email.parser import Parser
flag=False

emailaddress = '******'
# 注意使用开通POP,SMTP等的授权码
password = '*******'
pop3_server = '*******'

# 连接到POP3服务器:
server = poplib.POP3(pop3_server)
# 可以打开或关闭调试信息:
# server.set_debuglevel(1)
# POP3服务器的欢迎文字:
print(server.getwelcome())

# 身份认证:
server.user(self.emailaddress)
server.pass_(self.password)

# stat()返回邮件数量和占用空间:
messagesCount, messagesSize = server.stat()
print('messagesCount:', messagesCount)
print('messagesSize:', messagesSize)
# list()返回所有邮件的编号:
resp, mails, octets = server.list()
print("resp:", resp)
print("mails:", mails)
print("octets:", octets)

length = len(mails)

print(length)

for i in range(length):
    i=length-i
    resp, lines, octets = server.retr(i)
    msg_content=b'\r\n'.join(lines)
    msg = email.parser.BytesParser(policy=email.policy.default).parsebytes(msg_content)
    print('发件人', msg['from'])
    print('收件人', msg['to'])
    print('主题', msg['subject'])
    print('第一个收件人用户名', msg['to'].addresses[0].username)
    print('第一个发件人用户名', msg['from'].addresses[0].username)
    theme= msg['subject']
    email_content=[part.get_content() for part in msg.walk() if part.get_content_maintype() == 'text'][0]
    if theme=="启动查库任务分派机器人" and email_content==datetime.datetime.now().strftime("%Y%m%d"):
        flag=True
        break

server.quit()
print(flag)

二、解决编码问题

import chardet

#继承重写解析类
class BytesParser_new(email.parser.BytesParser):
    def parsebytes(self, text, headersonly=False):
        import chardet
        encoding=chardet.detect(text).get("encoding")
        text = text.decode(encoding, errors='surrogateescape')
        return self.parser.parsestr(text, headersonly)

msg = BytesParser_new(policy=email.policy.default).parsebytes(msg_content)

三、代码封装

import email
import poplib
import email.policy


class ReadEmail(object):
    def __init__(self, emailaddress, password, pop3_server):
        self.emailaddress = emailaddress
        self.password = password
        self.pop3_server = pop3_server
        self.server = poplib.POP3(pop3_server)

    def login(self):
        # 可以打开或关闭调试信息:
        self.server.set_debuglevel(1)
        # POP3服务器的欢迎文字:
        print(self.server.getwelcome())
        # 身份认证:
        self.server.user(emailaddress)
        self.server.pass_(password)

    def read(self):
self.login()
# stat()返回邮件数量和占用空间: messagesCount, messagesSize = self.server.stat() print('messagesCount:', messagesCount) print('messagesSize:', messagesSize) # list()返回所有邮件的编号: resp, mails, octets = self.server.list() print("resp:", resp) print("mails:", mails) print("octets:", octets) length = len(mails) print(length) for i in range(1, length): resp, lines, octets = self.server.retr(i) msg_content = b'\r\n'.join(lines) msg = email.parser.BytesParser(policy=email.policy.default).parsebytes(msg_content) # print('发件人', msg['from']) # print('收件人', msg['to']) print('主题', msg['subject']) # print('第一个收件人用户名', msg['to'].addresses[0].username) # print('第一个发件人用户名', msg['from'].addresses[0].username) theme = msg['subject'] email_content = [part.get_content() for part in msg.walk() if part.get_content_maintype() == 'text'][0] if theme == "系统退信/The email is returned": self.server.dele(i) print("删除邮件成功:", msg['subject']) self.server.quit() if __name__ == '__main__': emailaddress = '********' # 注意使用开通POP,SMTP等的授权码 password = '********' pop3_server = 'imap.qq.com' rm=ReadEmail(emailaddress,password ,pop3_server ) rm.read()

四、github最新smtplib代码

进一步对发送模块smtplib进行了封装,欢迎大家提意见
