python實現自動發送郵件

Python發送郵件成功的前提，應是先開啟授權碼。目前使用廣泛的郵箱有：163郵箱、qq郵箱等。

163郵箱開啟授權碼的方法如下圖：

 

qq郵箱開啟授權碼的方法如下圖：

 

接下來代碼的實現：

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.application import MIMEApplication
class SendEmail:
    def email(self,body, attach):
        # 發送郵箱
        sender = '[e-mail]'
        # 接收郵箱
        receivers = '[e-mail]'

        msg = MIMEMultipart()
        #郵箱的主題
        msg['Subject'] = '測試報告'
        msg['From'] = sender
        msg['To'] = receivers

        content = MIMEText(body,'html','utf-8')
        msg.attach(content)
        #添加附件，並命名
        attachment = MIMEApplication(open(attach, 'rb').read())
        attachment.add_header('Content-Disposition', 'attachment', filename='report.rar')
        msg.attach(attachment)

        try:
            #連接郵箱的服務器及端口號，以163郵箱為例
            smtpObj = smtplib.SMTP_SSL('smtp.163.com','465')
            #登錄郵箱：用戶名及密碼
            smtpObj.login(user='[e-mail]', password='xxx')
            smtpObj.sendmail(sender, receivers, str(msg))
            smtpObj.quit()
            print("郵件發送成功")
        except smtplib.SMTPException:
            print("Error: 無法發送郵件")


if __name__ == '__main__':
    #以同一目錄中的report.html為例
    with open("./report.html",'r',encoding="utf-8") as file:
        body=file.read()
    #以同一目錄中的report.rar為例添加附件
    SendEmail().email(body,"./report.rar")
