cors not working?

[fockarty]

Hi, i am trying to make something simple but i run into cors issues when i post something to /control the browser gives an cors error, in the response headers there in no mention of allow origins headers (or any response headers). What am i missing here?

from microdot import Microdot, send_file, Request,Response
from microdot.cors import CORS

import json

app = Microdot()
cors=CORS(app, allowed_origins=['*'], allow_credentials=True,handle_cors=True)

@app.route('/')
async def index(request):
return send_file('Sockets/web/index.html')

@app.route('/favicon.ico')
async def favicon(request):
return send_file('Sockets/web/favicon.ico')

@app.route('/assets/')
async def assets(request,file):
return send_file('Sockets/web/assets/'+file)

@app.route('/control/',methods=["GET", "POST","OPTIONS"])
async def assets(request):
obj=json.loads(request.body.decode(encoding='UTF-8'))
red=obj['kleur'][0]['r']
blue=obj['kleur'][0]['b']
green=obj['kleur'][0]['g']

print(f'{ red } { green } { blue } ' )
return Response(body="ok",status_code=200)

@app.route('/shutdown')
async def shutdown(request):
request.app.shutdown()
return 'The server is shutting down...'

app.run(debug=True)

the response headers:

HTTP/1 200 OK
Allow: GET, POST, OPTIONS, HEAD, OPTIONS
Access-Control-Allow-Methods: POST
Access-Control-Allow-Headers: content-type,test
Content-Length: 0
Content-Type: text/plain; charset=UTF-8

What's the CORS error? That is very important, there are many things that can fail with CORS.

[fockarty]

and solved the example says allowed_origins=['https://example.org'] but in case of * it shoul be allowed_origins='*'. dunno if this is always the case

[miguelgrinberg]

That is correct. A list of domains or '*' for all domains.
