Flask + flask-restful给出了奇怪的错误

Question

I've used Flask in a couple of projects, but never used the flask-restful package when creating restul APIs - so I thought I should give it a try.

However, I've come across a weird error that I can't understand - and the API doesn't work at all. The error message says

{
    "message": "Not Found. You have requested this URI [/api/v1.0/items] but did you mean /api/v1.0/items ?", 
    "status": 404
}

run.py

from my_project import app

if __name__ == '__main__':
    app.run(host=0.0.0.0, debug=app.config['DEBUG'])

my_project/_ init _.py

from flask import Flask

app = Flask(__name__)

from my_project.base import blueprint as BaseBluePrint
from my_project.api import blueprint as ApiBluePrint
app.register_blueprint(BaseBluePrint)
app.register_blueprint(ApiBluePrint, url_prefix='/api/v1.0')

my_project/api/_ init _.py

from flask import Blueprint
from flask.ext import restful

blueprint = Blueprint('api', __name__)
api = restful.Api(blueprint)

class ItemList(restful.Resource):
    def get(self):
        return false


api.add_resource(ItemList, '/items', endpoint='items')

What can cause this? Whatever I do, the error remains. Looking at the url_map from Flask, I can see my route in there - and it looks fine. When moving away from blueprints and keeping it all in one file, it works. Python v2.7 and flask-restful v0.2.12 (installed from pip on Ubuntu Precise).

Answer 1

I had similar problems related to trailing slashes, eg i defined api.com/endpoint and was sending request to api.com/endpoint/ and was having 404 errors.

Solution was to configure Flask application not to be strict about trailing slashes by: app.url_map.strict_slashes = False
