CORS does not protect a resource, such as an API endpoint, against unwanted access. Why does requesting a cross-origin resource using Postman work? Postman does not enforce CORS. The most important of these headers is Access-Control-Allow-Origin, which specifies the origins that are allowed to access the resources from the server. The browser will allow certain cross-origin responses based on these extra headers. These headers start with Access-Control.

NO ACCESS CONTROL ALLOW ORIGIN CODE

To allow cross-origin requests to be made, some changes need to be made to the server-side code to add extra headers to the HTTP response sent back to the browser client. When a request is made, the browser client adds an Origin header to the request to indicate where the request came from. CORS uses HTTP headers to indicate the origins that a browser should allow resources to be loaded from. To allow resource sharing between a server and a resource at a different origin, the browser uses a mechanism called cross-origin resource sharing (CORS). For example, it prevents malicious JavaScript on an attacker’s website from reading data and interacting with an embedded website in an iFrame that loads a website that the user may be logged in to. It prevents resources, such as API endpoints exposed by a server, from being accessible to a frontend website hosted at a different origin, such as another server. Why does this error happen? The same-origin policy is a browser security measure that restricts resource fetching from different origins. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

NO ACCESS CONTROL ALLOW ORIGIN INSTALL

I installed django-cors-headers and I added it to my install apps: INSTALLED_APPS = (. I can access other sites, just not my pythonanywhere site. Origin '' is therefore not allowed access. No 'Access-Control-Allow-Origin' header is present on the requested resource. But when I access my pythonanywhere URL using (url) I keep getting the below error: Hi, thank you for the reply! Yes, that is what I'm trying to do. And I'm not sure where I should be building the code for the mobile app, on pythonanywhere or elsewhere but I can't seem to get either to work.Īny help is greatly appreciated! thank you! I'm just trying to create a prototype for a mobile app at this point but I'm having trouble being able to communicate with my django backend that is on pythonanywhere. I've never created a mobile app before so I may be going about it all wrong, not sure. Which I was able to open in a browser but I can't http to my django app on pythonanywhere. I was able to get it resolved and installed but then when I tried to run ionic serve it gave me the following addresses but neither worked in a browser:īut then someone else's answer was I should do it on a local computer and not pythonanywhere so I tried that and was given the following addresses: I first tried installing it under my virtualenv on pythonanywhere (I had some trouble with that and raised the following issue:
