Python Pyorient查询到Json

我将OrientDB与Python3.5结合使用，并为我的记录创建了一个API。问题是我得到了这些记录，但我需要序列化这些记录

这是我的密码

from flask import Flask, request
from flask_restful import reqparse, abort, Api, Resource
import pyorient

app = Flask(__name__)
api = Api(app)
client = pyorient.OrientDB("localhost", 2424)
client.set_session_token( True )  # set true to enable the token based

client.db_open( "intera", "admin", "admin" )

### store this token somewhere
sessionToken = client.get_session_token()

### destroy the old client, equals to another user/socket/ip ecc.
del client

### create a new client
client = pyorient.OrientDB("localhost", 2424)

### set the previous obtained token to re-attach to the old session
client.set_session_token( sessionToken )

### now the dbOpen is not needed to perform database operations

### set the flag again to true if you want to renew the token
client.set_session_token( True )  # set true
client.db_open( "intera", "admin", "admin" )
new_sessionToken = client.get_session_token()

assert sessionToken != new_sessionToken


class TodoList(Resource):
    def get(self):
        query = client.command("select * from my_class")



api.add_resource(TodoList,'/todos')



if __name__ == '__main__':
    app.run(debug =True)

如何修复该错误并序列化这些记录
