[英]404 when accessing resource Flask-Restful
from flask import g, request, session, render_template, flash, redirect, url_for
from flask import current_app as app
@app.route('/')
def home():
return 'this works'
from flask_restful import Resource, Api
from app.extensions import api
class HelloWorld(Resource):
def get(self):
return {'Hello': 'World'}
api.add_resource(HelloWorld, '/test') # Getting a 404 for this route on http://127.0.0.1:5000/test
Extensions sets up the api variable: 扩展程序设置api变量:
api = Api()
api.init_app(app)
I cannot figure out why I get a 404 when trying to access an api resource? 我无法弄清楚为什么在尝试访问api资源时会收到404错误?
Ok, the problem seems to be that the below ordering is wrong. 好的,问题似乎在于以下顺序是错误的。 I must add resources before I init the api.
在初始化api之前,我必须添加资源。
api = Api()
api.init_app(app)
api.add_resource(HelloWorld, '/')
Fix: 固定:
api = Api()
api.add_resource(HelloWorld, '/')
api.init_app(app)
This is quite strange given that eg SQLAlchemy needs to call init_app before it is used... 鉴于例如SQLAlchemy需要在使用init_app之前调用init_app,这是很奇怪的。
