This error is showing after I keeps running ng serve --disable-host-check and have enable for all origin on python django rest framework
Access to XMLHttpRequest at 'localhost:8000/supplier/' from origin 'http://localhost:4200' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome-extension, edge, chrome-untrusted, https, isolated-app.

I am trying to deploy my application using below tech stack:
Angular - Frontend
Django - Backend
When I am trying to access over https my app the backend is giving following error
Not Found: /
[05/Jul/2021 00:57:08] "GET / HTTP/1.1" 404 2356
[05/Jul/2021 02:42:50] code 400, message Bad request version ('À\x14À')
[05/Jul/2021 02:42:50] You're accessing the development server over HTTPS, but it only supports HTTP.
You're using the development server to host the application, this is not suggested and does not work with https only http.
Use a production grade server like:
Apache
Nginx
Others
For more information visit the django-depolyment docs
You will also need to generate and sign a https certificate, for that I would suggest using Lets Encrpty
A different thread pointed out a couple of services that would require a client MTLS certificate, accept any cert, and then respond with information about the SSL handshake/certs.
HTTPS test server that checks client certificates
These endpoints both return HTML. Does anyone know of anything similar that returns application/json?
The URLs below will return application/json content upon successfully mutual TLS client certificate authentication. If no authentication is peformed, then HTTP error 403 is returned in the HTTP headers and the response is empty:
https://certauth.idrix.fr/json (TLS 1.2 only)
https://certauth.cryptomix.com/json (TLS 1.2 and TLS 1.3)
The json returned in case of success contains various technical information about the established connection.
I try to manage Apache Atlas APIs using WSO2 API Manager, when trying a get request like this for example :
http://{address_IP:port}/atlas/2.0.0-SNAPSHOT/v2/entity/bulk
Postman gives
101503 error connecting to the backend
I just figured out that the production endpoint does not allow Http request.
What shall I do to fix that?
I'am getting an error message from Angular whenever I try to make an AJAX call to an endpoint of my backend (on a separate domain, running Django 1.7):
Cross origin requests are only supported for protocol schemes: http,
data, chrome-extension, https, chrome-extension-resource
I do have django-corsheaders installed, CORS_ORIGIN_ALLOW_ALL = True and the middleware set up properly. So what's wrong?
I am not sure if this information is relevant, but I am still testing everything on a single host, meaning there is one XAMPP server running for the Angular frontend at localhost and one Gunicorn instance running at localhost:5000 for the backend.
I am testing a Rest server using Django Rest Framework. By following the tut from Django Rest website I successfully generated a proper API. But when I try to test with backbone.js to talk locally with that server, it seems fail to communicate together.
The server places at address: http://localhost:8080/users/
The client: http://localhost/client
This is the collection and the view in client
var Users = Backbone.Collection.extend({
url: 'http://localhost:8080/apis/',
});
The network after parsing shows status: canceled and type: pending
I suspect the port different caused the error. Could any point me out the correct way ? Thanks
The browser does not allow you to make POST/PUT ajax requests from localhost(:80) to localhost:8080, because of the Same Origin Policy requirement. In order for the browser to consider two addressed as having same origin, they must have the same protocol (http/https), domain name (localhost) and port number.
You can configure the web server at localhost:80 to proxy requests to localhost:8080. Most web servers support this functionality with a simple configuration change. If you are for instance using apache, see documentation.
Sample Apache proxy config:
ProxyPass /api http://localhost:8080/
ProxyPassReverse /api http://localhost:8080/
After this, you can access an address at localhost:8080/users with localhost/api/users:
var Users = Backbone.Collection.extend({
url: '/api/users',
});
