Get CORS error when connecting to web service REST M3

Hi M3 developer,
I try to consume a REST M3 web service by angular but the server responds with a CORS error (you can find the screetshoot attached)

I have browsed the cases in infor support on this subject. I found that :

-I must add the domain in mi.cors.allowed.domains (attached a screenshot) .

-I must to enable basic authentification in default router,i use http port ((attached a screenshot)):

-My code is very simple and I added in my header ( headers.append('Access-Control-Allow-Origin', 'http://localhost:4200');).

I tried all solution but the problem still existing.
Could you please help me .

Best Regards

Hi!

I'm not 100% sure, but I think it not Works with HTTP at all, you need HTTPS.

we use HTTPS and that CORS plugin with Chrome.

thank you very much, this is exactly the solution (she works with https and https with me)

change to HTTPS otherwise You should use a Proxy to skip CORS problem (not recommend)
