如何记录Flask-Restplus发送的封送消息

Question

考虑下面的最小示例：

from flask_restplus import Api, Resource, fields
from .models import User

ns = api.namespace('users', description='User related operations')

user = api.model('User', {
    'id': fields.Integer(readOnly=True, description='The user identifier'),
    'name': fields.String(required=True, description='The users name'),
    'password': fields.String(required=True, description='The users password')
})

@ns.route('/')
class UserList(Resource):
    @ns.doc('list_users')
    @ns.marshal_list_with(user)
    def get(self):
        data = User.query.all()
        print "Print the response here!"
        return data

我正在进行故障排除，并且我希望能够打印/记录Flask-RestPlus返回的JSON响应，我该如何做？

我自己突然很快就想明白了。使用marshal函数与使用@ns.marshal_list_with(用户)注释的作用相同

from flask_restplus import Api, Resource, fields, marshal
from .models import User
import json

ns = api.namespace('users', description='User related operations')

user = api.model('User', {
    'id': fields.Integer(readOnly=True, description='The user identifier'),
    'name': fields.String(required=True, description='The users firstName'),
    'password': fields.String(required=True, description='The users password')
})

@ns.route('/')
class UserList(Resource):
    @ns.doc('list_users')
    @ns.marshal_list_with(user)
    def get(self):
        data = User.query.all()
        print json.dumps(marshal(User.query.all(), user))
        return data
