HttpClient not sending requests without subscribe?

Question

Angular

Actually, the question is, is it normal that calling the get method of the HttpClient class, which is not followed by the subscribe method, does not lead to a request to the resource?
The request is like this:

this._httpClient.get('http://localhost:20019/api', { responseType: "text", withCredentials: true });

I also tried to call the pipe method, the same nonsense ...
It turns out that in fact the request would pass, the construction should end with subscribe?

Answer 1

Yes, observable without subscribe fails

Answer 2

Try httpClient.get(...).toPromise() , inside there will be a subscription and folding the result into a Promise. And the Promise itself can be "postponed for later" or thrown away :)
