Flask-Mail 如何将多个文件添加到邮件中？

Question

我想添加几个附件之类的文件，但是我看不懂怎么办。

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}

Answer 1

为了解决问题，我只需要添加 msg.attachments

Answer 2

您可以将 Attachment 个实例的列表提交给您的 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}
