2、发送邮件，并添加附件
file_path = 'file.xls' ws.save(file_path)
connection = mail.get_connection()
connection.open()
email1 = mail.EmailMessage(
'测试，谢谢！',
'没有内容',
'发件人@com.cn',
['收件人邮箱'],
connection=connection,
)
text = open(file_path, 'rb').read()
file_name = os.path.basename(file_path)
b = make_header([(file_name, 'utf-8')]).encode('utf-8')
email1.attach(b,text)
email1.send()
connection.close()效果：
注意在部署环境下，file_path需要写入绝对路径：
file_path = 'D:/wwwroot/Apache24/htdocs/file/PFMEA_' + title +'_RPL=1.xls'
