如何使用Python发送带有.csv附件的电子邮件[重复]

Question

这个问题已经在这里有了答案 ：

在Python smtplib中附加txt文件 （3个答案）

6年前关闭。

好的，我知道这里有一些问题可以解决，但是我找不到找到使其正常工作的方法。我认为它和下面的代码一样简单，但这不会附加我的文件。任何帮助将不胜感激。我对Python也很陌生。我应该导入一个邮件模块以使该功能正常工作吗？

import smtplib
fromaddr = "[e-mail]
toaddrs = "[e-mail]

msg = "help I cannot send an attachment to save my life"
attach = ("csvonDesktp.csv")

username = user
password = password

server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg, attach)
server.quit()

发送包含适当MIME类型的多部分电子邮件。

https://docs.python.org/2/library/email-
examples.html

所以可能是这样的（我测试过）：

import smtplib
import mimetypes
from email.mime.multipart import MIMEMultipart
from email import encoders
from email.message import Message
from email.mime.audio import MIMEAudio
from email.mime.base import MIMEBase
from email.mime.image import MIMEImage
from email.mime.text import MIMEText

emailfrom = "[e-mail]"
emailto = "[e-mail]"
fileToSend = "hi.csv"
username = "user"
password = "password"

msg = MIMEMultipart()
msg["From"] = emailfrom
msg["To"] = emailto
msg["Subject"] = "help I cannot send an attachment to save my life"
msg.preamble = "help I cannot send an attachment to save my life"

ctype, encoding = mimetypes.guess_type(fileToSend)
if ctype is None or encoding is not None:
    ctype = "application/octet-stream"

maintype, subtype = ctype.split("/", 1)

if maintype == "text":
    fp = open(fileToSend)
    # Note: we should handle calculating the charset
    attachment = MIMEText(fp.read(), _subtype=subtype)
    fp.close()
elif maintype == "image":
    fp = open(fileToSend, "rb")
    attachment = MIMEImage(fp.read(), _subtype=subtype)
    fp.close()
elif maintype == "audio":
    fp = open(fileToSend, "rb")
    attachment = MIMEAudio(fp.read(), _subtype=subtype)
    fp.close()
else:
    fp = open(fileToSend, "rb")
    attachment = MIMEBase(maintype, subtype)
    attachment.set_payload(fp.read())
    fp.close()
    encoders.encode_base64(attachment)
attachment.add_header("Content-Disposition", "attachment", filename=fileToSend)
msg.attach(attachment)

server = smtplib.SMTP("smtp.gmail.com:587")
server.starttls()
server.login(username,password)
server.sendmail(emailfrom, emailto, msg.as_string())
server.quit()
