Flask Python中的RESTful API示例

Question

Can someone show me examples of making a RESTful API which uses database information in Flask? I have no idea how to implement POST, PUT and DELETE and I always get the 405 error where I can't use the method in url.

Answer 1

Have you add request method in your routing? you can following reference from: flask-restful

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

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

class TodoSimple(Resource):
    def get(self):
        # do get something

    def put(self):
        # do put something

    def delete(self):
        # do delete something

    def post(self):
        # do post something

api.add_resource(TodoSimple, '/api/todo')

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

Answer 2

in flask-restful the HTTP actions (GET, PUT, POST, DELETE) have their corresponding method in the resource class, so is just a matter of defining those method in the resource (with the corresponding parameter defined in the routing)

I've also built a lightweight framework for building restful apis that makes it super easy to build apis. You can take a look at the code to have an idea of how an API can be built, configured and run, and of course, build on top of it
