Exploring Angular 5: Managing HTTP Headers and Utilizing URL Parameters

I am currently working on an Angular project that involves third-party authentication, which redirects to our app with additional information in the HTTP headers.

Here are the questions I have:

  1. What is the best way to extract the information from the HTTP headers in Angular 5?
  2. Similarly, how can I also access the URL's query string in Angular 5?

Thank you in advance for your assistance.

Answer №1

To retrieve the headers, pass observe: 'response' when making a request using Observable<HttpResponse> object.

For instance:

this.http.get('url', { observe: 'response' }).subscribe(response => {
    console.log(response.headers);
});
