headers not being set or set to nonsense about flask-cors HOT 7 CLOSED

Note: I am using version 2.1.2. I've been reading other bug reports and don't see anything quite like this, so I'm baffled as to what is happening. Especially that weird 'file://' value.

from flask-cors.

Further information: I'm importing like this.

from flask import Blueprint, g
from marshmallow import ValidationError
from ..errors import bad_request, not_found
from flask.ext.cors import CORS
import logging
from ..decorators import rate_limit

api = Blueprint('api', __name__)
CORS(api)
logging.getLogger('flask_cors').level = logging.DEBUG

@api.errorhandler(ValidationError)
def validation_error(e):
    return bad_request(e.args[0])

@api.errorhandler(400)
def bad_request_error(e):
    return bad_request('invalid request')

@api.errorhandler(404)
def not_found_error(e):
    return not_found('item not found')

@api.after_request
def after_request(response):
    if hasattr(g, 'headers'):
        response.headers.extend(g.headers)
    return response

Thanks so much for the detailed report. I really appreciate it!

Can you show me an example CURL request and response? Please ensure the Origin header is set.

Also, if you are able to increase logging verbosity to show debug messages that would be very helpful in debugging what Flask-CORS is doing in this case. There is an example of how to do this here: https://github.com/corydolphin/flask-cors/blob/master/examples/app_based_example.py#L24

Thanks again for the detailed report!

Sorry for not getting back. I'll try that, ensuring the Origin is set soon.

from flask-cors.

So! I got this on a first run without modification:
INFO:api.cors:The request's Access-Control-Request-Method header does not match allowed methods. CORS headers will not be applied.
Then it applied this header:
Access-Control-Allow-Origin →file://

from flask-cors.

Thanks for posting back and working with me Brooke! Really appreciate it.

Can you post the curl you made along with as much logging context around
that message as possible?
