無法使用具有多個附件和多個收件人的python發送郵件[to，cc，bcc]

Question

以下是我的代碼。它無法發送解析級別的郵件。無法理解實際問題。 OS是由AWS提供的Ubuntu 14.04服務器。它必須發送帶有兩個附件的電子郵件。

import smtplib 
import sys 
from email.MIMEMultipart import MIMEMultipart 
from email.MIMEText import MIMEText 
from email.MIMEBase import MIMEBase 
from email import encoders 

fromaddr = "user@comany.com" 
toaddr = str(sys.argv[1]).split(",") 
ccaddr = str(sys.argv[2]).split(",") 
bccaddr = str(sys.argv[3]).split(",") 

subject = None 
body = None 

print sys.argv 

with open("subject.txt") as f1: 
    subject = f1.read() 

with open("body.txt") as f2: 
    body = f2.read() 

msg = MIMEMultipart() 

msg['From'] = fromaddr 
msg['To'] = toaddr 
msg['Cc'] = ccaddr 
msg['Bcc'] = bccaddr 
msg['Subject'] = subject.replace("DD",str(sys.argv[4])[6:2]).replace("MM",str(sys.argv[4])[4:2]).replace("YYYY",str(sys.argv[4])[0:4]) 

body = body.replace("DD",str(sys.argv[4])[6:2]).replace("MM",str(sys.argv[4])[4:2]).replace("YYYY",str(sys.argv[4])[0:4]) 

msg.attach(MIMEText(body, 'plain')) 

for filename in str(sys.argv[5]).split(";"): 
    attachment = open(filename, "rb") 
    part = MIMEBase('application', 'octet-stream') 
    part.set_payload((attachment).read()) 
    encoders.encode_base64(part) 
    part.add_header('Content-Disposition', "attachment; filename= %s" % filename) 
    msg.attach(part) 

server = smtplib.SMTP('smtp.gmail.com', 587) 
server.ehlo() 
server.starttls() 
server.ehlo() 
server.login(fromaddr, "password") 
server.sendmail(fromaddr, toaddr, msg.as_string()) 
server.quit() 

以下是錯誤：

File "send_mail.py", line 49, in <module> 
    server.sendmail(fromaddr, toaddr, msg.as_string()) 
    File "/usr/lib/python2.7/email/message.py", line 137, in as_string 
    g.flatten(self, unixfrom=unixfrom) 
    File "/usr/lib/python2.7/email/generator.py", line 83, in flatten 
    self._write(msg) 
    File "/usr/lib/python2.7/email/generator.py", line 115, in _write 
    self._write_headers(msg) 
    File "/usr/lib/python2.7/email/generator.py", line 164, in _write_headers 
    v, maxlinelen=self._maxheaderlen, header_name=h).encode() 
    File "/usr/lib/python2.7/email/header.py", line 410, in encode 
    value = self._encode_chunks(newchunks, maxlinelen) 
    File "/usr/lib/python2.7/email/header.py", line 370, in _encode_chunks 
    _max_append(chunks, s, maxlinelen, extra) 
    File "/usr/lib/python2.7/email/quoprimime.py", line 97, in _max_append 
    L.append(s.lstrip()) 
AttributeError: 'list' object has no attribute 'lstrip' 

Answer 1

與yagmail試試吧。免責聲明：我是yagmail的開發者。

import yagmail 
yag = yagmail.SMTP("user@comany.com", "password") 
yag.send(toaddrs, subject, body, str(sys.argv[5]).split(";"), ccaddrs, bccaddrs) 
#  ^to  ^subject^body ^attachments  ^cc ^bcc 

這幾乎是「做我想做的」，你可以提供字符串或一個字符串列表，甚至省略任何參數，這將是明智的。另一件很酷的事情是這裏的附件是一串字符串;其中每個將被試圖加載爲文件（具有正確的mimetype）。

使用pip install yagmail安裝

我有同樣的問題，當我試圖在味精喂列表[「要」]。我將列表更改爲字符串，我擺脫了這個問題。 ['test@my.com'，'another@my.com'] =>'test@my.com，another@my.com'
