Python中Flask-RESTful编写API接口(小白入门)

from flask import Flask
from flask_restful import Api, Resource

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

class HelloWorld(Resource):

  return {'hello': 'world'}

api.add_resource(HelloWorld, '/')

if __name__ == '__main__':

  return {todo_id: todos[todo_id]}

 def put(self, todo_id):
  todos[todo_id] = request.form['data']
  return {todo_id: todos[todo_id]}

api.add_resource(TodoSimple, '/')

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

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

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

parser = reqparse.RequestParser()
parser.add_argument('task', type=str)
parser.add_argument('name', type=str)


# 获取 & 更新
class Get_Modify(Resource):

  args = parser.parse_args()
  print(args)
  return args, 201


api.add_resource(Get_Modify, '/get_modify')

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

from flask import Flask
