关于使用python搭建微信公众号通过 werobot 自动回复用户消息的问题

[xchjian]

希望通过werobot获取用户发来的消息，查询mysql后将结果发送给用户。麻烦各位大神给看看是哪里的问题？

使用的代码如下：
from werobot import WeRoBot
import pymysql
robot = WeRoBot(
token = 'xxxx',
encoding_aes_key = 'xxxx',
app_id = 'xxxx'
)
@robot.text
def echo(message):
conn = pymysql.Connect( host = 'localhost', user = 'xxxx',password = 'xxxx',db = 'xxxx',charset = 'utf8')
cursor = conn.cursor()
cursor.execute("select xxxx from xxxx where name = %s",message.content)
ret = cursor.fetchone()
cursor.close()
conn.close()
return ret

报错的消息为：
Traceback (most recent call last):
File "/xxxx/lib/python3.7/site-packages/flask/app.py", line 2311, in wsgi_app
response = self.full_dispatch_request()

return reply.render()

@xchjian 是的

已解决，return无法返回元组，转化为字符串后可以返回
