Python透過Gamil寄送Email並且附加檔案

如果執行中出現
"smtplib.SMTPAuthenticationError: (535, '5.7.8 Username and Password not accepted. Learn more at\n5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 g66sm2224117qgf.37 - gsmtp') http://stackoverflow.com/questions/10147455/how-to-send-an-email-with-gmail-as-provider-using-python/27515833#27515833"
錯誤，代表有權限的問題。

可以去Google的說明連結或是直接這邊調整權限

要調整成
低安全性應用程式

[PS如果有用兩階段認證，電話的就好像還找不到解決方式，建議另外建立個MAIL來寄送]


範例Code

#!/usr/bin/env python
# encoding: utf-8

import os
import sys
import smtplib
from email import encoders
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart

COMMASPACE = ', '

def main():
    sender = '你的EMAIL'
    gmail_password = '你的EMAIL密碼'
    recipients = ['收件人01的EMAIL','收件人02的EMAIL']
    
    # 建立郵件主題
    outer = MIMEMultipart()
    outer['Subject'] = '主題'
    outer['To'] = COMMASPACE.join(recipients)
    outer['From'] = sender
    outer.preamble = 'You will not see this in a MIME-aware mail reader.\n'

    # 檔案位置 在windows底下記得要加上r 如下 要完整的路徑
    attachments = [r'C:\Users\witkaiy\OneDrive\code sample\work\your_file.xls']

    # 加入檔案到MAIL底下
    for file in attachments:
        try:
            with open(file, 'rb') as fp:
                print ('can read faile')
                msg = MIMEBase('application', "octet-stream")
                msg.set_payload(fp.read())
            encoders.encode_base64(msg)
            msg.add_header('Content-Disposition', 'attachment', filename=os.path.basename(file))
            outer.attach(msg)
        except:
            print("Unable to open one of the attachments. Error: ", sys.exc_info()[0])
            raise

    composed = outer.as_string()

    # 寄送EMAIL
    try:
        with smtplib.SMTP('smtp.gmail.com', 587) as s:
            s.ehlo()
            s.starttls()
            s.ehlo()
            s.login(sender, gmail_password)
            s.sendmail(sender, recipients, composed)
            s.close()
        print("Email sent!")
    except:
        print("Unable to send the email. Error: ", sys.exc_info()[0])
        raise

if __name__ == '__main__':
    main()

目前測試是可以寄送MAIL沒有問題
