Question

我正在尝试使用python脚本发送邮件。我没有依恋就尝试过它。

现在我尝试使用附件我收到了断言错误。

以下是代码：

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders
import os
import time
import random
msg_from = "xyz@abc.com"
to =  "xyz@abc.com"
text = "test-Hello"
subject = "Test"
f = "output1.pdf"

def generate_message_id(msg_from):
    domain = msg_from.split("@")[1]
    r = "%s.%s" % (time.time(), random.randint(0, 100))
    mid = "<%s@%s>" % (r, domain)
    return mid

def send_mail(msg_from, to, subject, text,
    files=[],server="10.10.10.10", debug=False):
    assert type(to)==list
    assert type(files)==list

    msg = MIMEMultipart()
    msg['From'] = msg_from
    msg['To'] = COMMASPACE.join(to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject

    text = text.encode("utf-8")
    text = MIMEText(text, 'plain', "utf-8")
    msg.attach(text)

    msg.add_header('Message-ID', generate_message_id(msg_from))

    for file in files:
        part = MIMEBase('application', "octet-stream")
        part.set_payload( open(f,"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"'
                        for file in files:
        part = MIMEBase('application', "octet-stream")
        part.set_payload( open(f,"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"'
                       % os.path.basename(file))
        msg.attach(part)

    if not debug:
        smtp = smtplib.SMTP(server)
        smtp.sendmail(msg_from, to, msg.as_string())
        smtp.close()

    return msg
send_mail(msg_from, to, subject, text,files=[],server="10.10.10.10", debug=False)

我得到的错误：

Traceback (most recent call last):
File "testmail1.py", line 53, in <module>
   send_mail(msg_from, to, subject, text,files=[],server="10.10.10.10", debug=False)
File "testmail1.py", line 24, in send_mail
   assert type(to)==list
AssertionError

我使用的是linux os并使用python 2.7

请帮我解决

Answer 1

您的to字段应该是一个列表，因为理论上您可以将您的电子邮件发送给多个人。所以我建议：

to =  ["xyz@abc.com"]

send_mail方法首先检查您的to字段是否为列表，这就是您收到错误的原因。
