Python 发邮件(500, b‘Error: bad syntax‘)
我遇到这问题的时候的源代码：
try:
smtp=smtplib.SMTP()
smtp.connect('smtp.163.com',25)
smtp.login('...','...')
smtp.sendmail('[email protected]','[email protected]',MIMEText('老八秘制小汉堡').as_string())
smtp.close()
except Exception as e:
print(e)
然后
(220, b'163.com Anti-spam GT for Coremail System (163com[20141201])')
(500, b'Error: bad syntax')
我觉得十分莫名其妙，网上有人说是因为socket.getfqdn()不是主机地址，然后搬出来一堆我看不懂得代码，，，（self没有在类里面用，一堆没啥用的变量）
我就去掉try了，一行一行的试，然后打错了，返回了一关键错误代码
>>> smtp.sendmail('[email protected]',['[email protected]'],MIMEText('wdwd').as_string())
Traceback (most recent call last):
File "" , line 1, in <module>
smtp.sendmail('[email protected]',['[email protected]'],MIMEText('wdwd').as_string())
File "A:\Python\lib\smtplib.py", line 871, in sendmail
raise SMTPSenderRefused(code, resp, from_addr)
smtplib.SMTPSenderRefused: (503, b'Error: send HELO/EHLO first', '[email protected]')
我一看，原来SMTP类还有个ehlo函数(要写在login函数之前)不过不能直接用，参数要写邮箱的smtp地址：
>>> smtp.ehlo('smtp.163.com')
(250, b'mail\nPIPELINING\nAUTH LOGIN PLAIN\nAUTH=LOGIN PLAIN\ncoremail ............................................\nSTARTTLS\n..........') #原来的东西被我用点替换了，反正我觉得暴露出去挺危险的
然后看这架势就大功告成了，最后在登入
>>> smtp.login('.......','..........')
(235, b'Authentication successful')
这下就可以愉快的sendmail了
>>> smtp.sendmail('[email protected]',['[email protected]'],MIMEText('wdwd').as_string())
{
}
