I am currently developing an Angular application that utilizes ng-resource. The backend service API is created using Asp.Net Core web api and CORS has been enabled.
Here is the code snippet for service.js:
.factory('D2Service', ['$resource', function ($resource) {
return $resource('http://localHost:5001/api/D2/:id',
{ id: '@id' },
{
update: { method: 'PUT' }
});
}])
Despite this, when making the call D2Service.update(model.d); in the controller, I encountered the following error:
XMLHttpRequest cannot load http://localhost:5001/api/D2. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8082' is therefore not allowed access.
Strangely,
D2Service.get({ id: model.id })....Below are the details of the request/response as monitored using Fiddler.
