Question

我尝试将包含本地计算机附件的电子邮件发送到Gmail帐户。

这是我的代码：

import smtplib
from os.path import basename
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.utils import COMMASPACE, formatdate
from email import Encoders

def send_mail(send_from, send_to, body, text, files=None,server="127.0.0.1"):
    try:
        assert isinstance(send_to, list)
    except AssertionError as e:
        print e

    msg = MIMEMultipart(
        From=send_from,
        To=COMMASPACE.join(send_to),
        Date=formatdate(localtime=True),
        Subject=body
    )
    msg.attach(MIMEText(text))

    for f in files or []:
        with open(f, "rb") as fil:
            msg.attach(MIMEApplication(fil.read(), Content_Disposition='attachment; filename="%s"' % basename(f)))

    try:
        smtp = smtplib.SMTP(server)
        smtp.sendmail(send_from, send_to, msg.as_string())
        print "Successfully sent mail."
    except SMTPException:
        print "Error: unable to send email"

    smtp.close()

基于this问题的接受答案。

以下是调用它的代码：

send_from = "name.surname@my-company.com"
send_to = "lcuky_recipient@gmail.com"
subject = "testEmail", 
text = "This is a test. Hopefully, there's a file attached to it."
files = ".././dudewhat.csv"
send_mail(send_from, send_to, subject, text, files)

但这是我得到的回报：

File "belo_monthly.py", line 138, in <module>
    send_mail(send_from, send_to, subject, text, files)
  File "belo_monthly.py", line 26, in send_mail
    Subject=body
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/email/mime/multipart.py", line 36, in __init__
    MIMEBase.__init__(self, 'multipart', _subtype, **_params)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/email/mime/base.py", line 25, in __init__
    self.add_header('Content-Type', ctype, **_params)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/email/message.py", line 408, in add_header
    parts.append(_formatparam(k.replace('_', '-'), v))
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/email/message.py", line 52, in _formatparam
    value = utils.encode_rfc2231(value[2], value[0], value[1])
IndexError: tuple index out of range

我错过了什么？

Answer 1

这是你的问题：

subject =“testEmail”，

最后删除逗号，事情应该有效

Answer 2

您正在检查列表的实例，但解析的值是字符串。尝试更改

send_to = "lcuky_recipient@gmail.com"

到

send_to = ["lcuky_recipient@gmail.com"]

或修改逻辑

尝试使用python发送电子邮件，使IndexError：tuple超出范围
