Question

当我使用它来发送txt文件，图像或音频时，我有下面的代码可以正常工作。但是，当我尝试发送zip文件，rar文件或任何其他没有自己MIME（与MIMEText，MIMEImage或MIMEAudio无关）的文件时，它不起作用。

总之，每当我到达else部分（MIMEBase命令）时，我都会做错事并得到错误：

e.send_mail(TARGET, SUBJECT, "file.zip")    
msg.attach(part)         //two lines after the else's end
AttributeError: 'str' object has no attribute 'append'

代码：

def send_mail(self, target, subject, *file_names):
    """
    send a mail with files to the target
    @param target: send the mail to the target
    @param subject: mail's subject
    @param file_names= list of files to send
    """
    msg = email.MIMEMultipart.MIMEMultipart()
    msg['From'] = self.mail
    msg['To'] = email.Utils.COMMASPACE.join(target)
    msg['Subject'] = subject
    for file_name in file_names:
        f = open(file_name, 'rb')
        ctype, encoding = mimetypes.guess_type(file_name)
        if ctype is None or encoding is not None:
            ctype = 'application/octet-stream'
        maintype, subtype = ctype.split('/', 1)
        # in case of a text file
        if maintype == 'text':
            part = MIMEText(f.read(), _subtype=subtype)
        # in case of an image file
        elif maintype == 'image':
            part = MIMEImage(f.read(), _subtype=subtype)
        # in case of an audio file
        elif maintype == 'audio':
            part = MIMEAudio(f.read(), _subtype=subtype)
        # any other file
        else:
            part = MIMEBase(maintype, subtype)
            msg.set_payload(f.read())
        part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(file_name))
        msg.attach(part)
        f.close()
    # ssl server doesn't support or need tls, so don't call server_ssl.starttls()
    self.server_ssl.sendmail(self.mail, target, msg.as_string())
    #server_ssl.quit()
    self.server_ssl.close()

我见过类似的代码，但我不明白我的错误。

你可以解释一下我搞砸了什么吗？

谢谢你！

Answer 1

if it helps anyone here is the answer: the main problem was that I changed the msg payload instead of the zip file's

 <ListView
    android:id="@+id/listDevicesMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

添加到电子邮件的zip文件
