TypeError: Object of type function is not JSON serializable when using flask_jwt_extended int RESTful API

Question

我正在使用 Flask 构建 REST API。我正在使用 postman 测试在我的数据库中创建新项目的路由，但前提是用户已登录。注册和登录的路由运行良好，最后一个 returns使用 flask_jwt_extended 模块的令牌。当我向我的“/api/notes”发送 post 请求（在数据库中创建一个新笔记）时，我收到以下错误消息：

" (...) raise TypeError(f'Object of type {o.class.name} '

TypeError：类型函数的对象不是JSON可序列化的

对于请求，我正在使用 postman 的授权选项卡。类型：Bearer Token，字段中是我的令牌（带引号和不带引号都试过了）

今天早上我遇到了这个错误，在实施我的一对多关系之前，但我通过在 Barear 令牌字段中将我的 VERY_LONG_TOKEN 替换为“VERY_LONG_TOKEN” 来让它工作。我认为因为令牌包含点，所以它被解释为一个函数。但是实现关系后，我去测试，又报这个错

我的note.py文件：

from flask import request, Response, jsonify
from app.models import User, Note
from flask_restful import Resource
from flask_jwt_extended import jwt_required, get_jwt_identity

class NotesApi(Resource):
    def get(self):
        notes = Note.objects().to_json()
        return Response(notes, mimetype="application/json", status=200)

    @jwt_required  
    def post(self):  # post method I'm making a request for
        print("fool")  # this doesn't get printed  ->  not reaching 
        user_id = get_jwt_identity()
        data = request.get_json(force=True)
        if data:
            user = User.objects(id=user_id) # logged in user
            note = Note(**data, user_author=user) # creates note with the author
            note.save()
            user.update(push__notes=note) # add this note to users notes
            user.save()
            id = str(note.id)
            return {'id': id}, 200
        else:
            return {'error': 'missing data'}, 400

我的models.py:

from app import db  # using mongodb
from datetime import datetime
from flask_bcrypt import generate_password_hash, check_password_hash

class Note(db.Document):
    title = db.StringField(max_length=120,required=True)
    content = db.StringField(required=True)
    status = db.BooleanField(required=True, default=False)
    date_modified = db.DateTimeField(default=datetime.utcnow)
    user_author = db.ReferenceField('User')
    
class User(db.Document):
    username = db.StringField(max_length=100, required=True, unique=True)
    email = db.StringField(max_length=120, required=True, unique=True)
    password = db.StringField(required=True)
    remember_me = db.BooleanField(default=False)
    notes = db.ListField(db.ReferenceField('Note', reverse_delete_rule=db.PULL)) # one-many relationship

    def hash_password(self):
        self.password = generate_password_hash(self.password).decode('utf8')

    def check_password(self, password):
        return check_password_hash(self.password, password)


User.register_delete_rule(Note, 'user_author', db.CASCADE)

初始化.py:

from flask import Flask
from config import Config  # my config class to set MONGOBD_HOST and SECRET_CLASS
from flask_mongoengine import MongoEngine
from flask_restful import Api
from flask_bcrypt import Bcrypt
from flask_jwt_extended import JWTManager

app = Flask(__name__)
app.config.from_object(Config)
db = MongoEngine(app)
api = Api(app)
bcrypt = Bcrypt(app)
jwt = JWTManager(app)

from app.resources.routes import initialize_routes
initialize_routes(api)

resources/routes.py:

from .note import NotesApi, NoteApi
from .auth import SignupApi, LoginApi

def initialize_routes(api):
    api.add_resource(NotesApi, '/api/notes')
    api.add_resource(NoteApi, '/api/note/<id>')
    api.add_resource(SignupApi, '/api/auth/signup')
    api.add_resource(LoginApi, '/api/auth/login')

文件夹结构：

app
  |_ resources
      |_ auth.py  # signup working well, login also working, return a token (type = String)
      |_ note.py
      |_ routes.py
  |_ __init__.py
  |_ models.py
config.py
appname.py  #just import app and do a app.run()

我的 post 请求正文：

{
   "title": "test0",
   "content": "test0"  
}

有没有人遇到过或知道如何解决？

编辑：添加了更多代码信息

看起来 flask-jwt-extended 在周末发布了一个新版本。作为 API 更改的一部分，@jwt_required 装饰器现在是 @jwt_required()

去掉对我有用的 HTTP 状态代码。示例

替换：

return {'id': id}, 200

与：

return {'id': id}

或：

resp = jsonify({'id': id})

resp.status_code = 200

return resp
