如何通过Flask-Restful API使用参数

from flask import Flask
from flask_restful import Api, Resource

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

class User(Resource):
    def get(self, user_id):
        # 根据user_id获取用户信息
        return {'user_id': user_id}

api.add_resource(User, '/user/<int:user_id>')

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

from flask import Flask, request
from flask_restful import Api, Resource

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

class UserList(Resource):
    def get(self):
        # 获取查询参数
        page = request.args.get('page', default=1, type=int)
        limit = request.args.get('limit', default=10, type=int)
        
        # 根据查询参数获取用户列表
        users = get_users(page, limit)
        
        return {'users': users}

api.add_resource(UserList, '/users')

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

from flask import Flask, request
from flask_restful import Api, Resource

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

class User(Resource):
    def post(self):
        # 获取请求体参数
        data = request.get_json()
        name = data.get('name')
        age = data.get('age')
        
        # 创建新用户
        user = create_user(name, age)
        
        return {'user_id': user.id}

api.add_resource(User, '/user')

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