在flask-restful中序列化UUID对象

from flask import Flask, jsonify
from flask_restful import Api, Resource
from marshmallow import Schema, fields
import uuid

app = Flask(__name__)
api = Api(app)

class MyResource(Resource):
    def get(self):
        my_uuid = uuid.uuid4()
        schema = MySchema()
        result = schema.dump({'uuid': my_uuid})
        return jsonify(result)

class MySchema(Schema):
    uuid = fields.UUID()

api.add_resource(MyResource, '/myresource')

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

from flask import Flask, jsonify

app = Flask(__name__)
api = Api(app)

class MyResource(Resource):
    def get(self):
        my_uuid = uuid.uuid4()
        result = {'uuid': str(my_uuid)}  # 将UUID转换为字符串
        return jsonify(result)
