What is the best way to retrieve data from a REST API using an authentication token in Angular 7?

My goal is to retrieve data from an API located at this URL: ''. I have properly set up all the required modules...

I attempted to access the API using the 'get()' method of the 'HttpClient' class like so: get(this.api, {headers: apiheader})

const httpOptions = {
      headers: new HttpHeaders({
          'Content-type': 'application/json',
          'Autorization': 'EpCuVuAOPGfoXNyXtDxDxNIozMxQ
                           7TC9W9C9FBlZsgUExQLH2zNOmFmWKnMBKKPE'
      })
};
api="http://apis.coursefrenzy.com/courses/";
getUser(){
    return this.http.get(this.api, {headers: httpOptions.headers});
}

However, when I subscribe to this method and log the data to the console, an error message appears...

Access to XMLHttpRequest at '' from origin 'http://localhost:6565' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.enter image description here

Answer №1

To enable CORS in your API, make sure to specify the origin parameter. For instance, within the .NET Core startup file:

builder.WithOrigins("http://localhost:4200")
