python 透過 google smtp server 發信的方法

python code‧‧‧

import smtplib
    to = 'where@gmail.com'
    server = "smtp.gmail.com"
    #port = 465 # ssl
    port = 587 # tls
    gmail_user = 'youraccount@gmail.com'
    gmail_pwd = 'yourpassword or application password'
    #smtpserver = smtplib.SMTP_SSL(server, long(port)) # ssl
    smtpserver = smtplib.SMTP(server, long(port)) # tls
    smtpserver.ehlo()
    smtpserver.starttls() # tls
    smtpserver.login(gmail_user, gmail_pwd)
    header = 'To:' + to + '\n' + 'From: ' + gmail_user + '\n' + 'Subject:test \n'
    print header
    msg = header + '\n this is test \n\n'
    smtpserver.sendmail(gmail_user, to, msg)
    print 'done!'
    smtpserver.quit()

*如果你有使用兩階段驗證，必須先到 google 個人設定頁，增加應用程式密碼，smtp 才會驗證通過…
