import os.path
import datetime
import smtplib
import codecs, collections

import zipfileJPN as zipfile
import unittest, time, re, os, sys,datetime, shutil
import MimeWriter, mimetools, base64, StringIO

from email import Encoders

    for i in files:
        filename =""
        filename=i
        zip.write(attach_file['path']+"/"+(filename.decode("cp932")).encode("cp932"))

4. 설명

1. python을 사용하여 메일 보내기

def send(from_addr, to_addrs, cc_addrs, msg):
    smtp = smtplib.SMTP("localhost:host")#要変更
    smtp.sendmail(from_addr, to_addrs+cc_addrs, msg.as_string())
    smtp.close()

3. zip 파일 첨부

  zf = tempfile.TemporaryFile(prefix='mail', suffix='.zip')
    zip = zipfile.ZipFile(zf, 'w')
    files = os.listdir(attach_file['path'])
    for i in files:
        filename =""
        filename=i
        zip.write(attach_file['path']+"/"+(filename.decode("cp932")).encode("cp932"))
    zip.close()
    zf.seek(0)

4. 첨부 파일 이름에 일본어 사용

import zipfileJPN as zipfile
