Prevent CORS in flask (python)
I face CORS when flask provide static file. but Flask-Cors
dose not work correctly….
Env
- Flask==1.1.1
How to solve
Use decorator
and send_from_directory
, instead of default static doc
from flask import Flask, send_from_directory
app = Flask(__name__, static_url_path="")
def res_decorator(f):
def func(*args, **kwargs):
resp = make_response(f(*args, **kwargs))
resp.cache_control.no_cache = True
# avoid CORS
resp.headers['Access-Control-Allow-Origin'] = '*'
return resp
return update_wrapper(func, f)
@app.route('/static/<path:path>')
@res_decorator
def static_files(path):
return send_from_directory('static', path,cache_timeout=0)
