[Python知识库]Python装饰器与日志创建和邮件发送不得不说的秘密

定义logit类

from functools import wraps
import smtplib
from email.mime.text import MIMEText
from email.header import Header
import time
 
class logit(object):
    def __init__(self, logfile='out.log'):
        self.logfile = logfile
 
    def __call__(self, func):
        @wraps(func)
        def wrapped_function(*args, **kwargs):
            log_string = func.__name__ + " was called"
            print(log_string)
            # 打开logfile并写入
            with open(self.logfile, 'a') as opened_file:
                # 现在将日志打到指定的文件
                opened_file.write(log_string + '\n')
            # 现在，发送一个通知
            self.notify()
            return func(*args, **kwargs)
        return wrapped_function
 
    def notify(self):
        # logit只打日志，不做别的
        pass

@logit()
def myfunc1():
    pass
myfunc1()

创建logit的子类email_logit

class email_logit(logit):
    '''
    一个logit的实现版本，可以在函数调用时发送email给管理员
    '''
    def __init__(self, email='xxxxxxx', *args, **kwargs):
        self.email = email
        super(email_logit, self).__init__(*args, **kwargs)
         # 第三方 SMTP 服务
        self.mail_host="smtp.qq.com"       #设置服务器:这个是qq邮箱服务器，直接复制就可以
        self.mail_pass="xxxxxxx"           #邮箱授权码
        self.sender = 'xxxxxxx'      #你的邮箱地址 
        self.receivers = [email]  # 收件人的邮箱地址，可设置为你的QQ邮箱或者其他邮箱，可多个
        
    def notify(self):

        receivers = self.receivers  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱
        
 
        # 三个参数：第一个为文本内容，第二个 plain 设置文本格式，第三个 utf-8 设置编码
        content = "日志创建"+time.strftime("%a %b %d %H:%M:%S %Y", time.localtime()) 
        message = MIMEText('content', 'plain', 'utf-8')
        message['From'] = Header("测试", 'utf-8')   # 发送者
        message['To'] =  Header("测试", 'utf-8')        # 接收者
        
        subject = "日志创建"+ time.strftime("%a %b %d %H:%M:%S %Y", time.localtime()) 
        message['Subject'] = Header(subject, 'utf-8')


        try:
            smtpObj = smtplib.SMTP_SSL(self.mail_host, 465) 
            smtpObj.login(self.sender,self.mail_pass)  
            smtpObj.sendmail(self.sender, self.receivers, message.as_string())
            smtpObj.quit()
            print('邮件发送成功')
        except smtplib.SMTPException as e:
            print('邮件发送失败')

@email_logit()
def myfunc2():
    pass
