【问题描述】：

我想添加几个文件，比如附件，但我不明白怎么做。

我的代码现在看起来像。

@form.post('/')
def get_data_from_form():
    message = request.form['message']
    grecaptcha = request.form['g-recaptcha-response']
    remote_ip = request.remote_addr
    files = request.files.getlist('file')
    msg = Message('EMAIL FROM FORM', recipients=['admin@****'])
    if check_recaptcha(grecaptcha, remote_ip):
        for file in files:
            mimetype = file.content_type
            filename = secure_filename(file.filename)
            msg.attachments = file
            msg.attach(filename, mimetype)
        msg.body = message
        try:
            mail.send(msg)
            return 'msg': 'The message has sent'
        except Exception as err:
            logger.debug(err)
            return 'msg': False

【问题讨论】：

这能回答你的问题吗？ Flask WTF to flask-mail attachment?

不行，我知道怎么附件一个文件，我需要添加几个文件

【参考方案1】：

为了解决问题，我只需要添加 msg.attachments

【参考方案2】：

您可以将Attachment 实例列表提交给您的Message 对象以执行此操作。请参阅下面的示例

from flask_mail import Message, Attachment
from werkzeug.utils import secure_filename
@form.post('/')
def get_data_from_form():
    message = request.form['message']
    remote_ip = request.remote_addr
    if check_recaptcha(grecaptcha, remote_ip):
        files = request.files.getlist('file')
        attachments = [
            Attachment(filename=secure_filename(file.filename), content_type=file.content_type, data=file.read())
            for file in files]
        msg = Message(subject='EMAIL FROM FORM', recipients=['admin@****'], body=message,
                      attachments=attachments)
        try:
            mail.send(msg)
            return 'msg': 'The message has sent'
        except Exception as err:
            logger.debug(err)
            return 'msg': False
