发送邮件

from flask.ext.mail import Mail, Message
msg = Message(邮件标题,
sender='发件人地址',
recipients=['多个收件人地址']
)
# 添加多个附件
for document in documents_path:
# 文件的文件名
file_name = os.path.basename(document)
with current_app.open_resource(document) as fp:
# file_name.encode("utf-8") 对文件名进行编码
# current_app.config['MIME_TYPE'][os.path.splitext(file_name)[1]] 通过后缀名，获取MIME格式
msg.attach(file_name.encode("utf-8"), current_app.config['MIME_TYPE'][os.path.splitext(file_name)[1]], fp.read())

msg.body = 邮件正文
# 发送邮件
mail.send(msg)
