Angular HttpClient params with method GET do not work

问题

I wanna ask you about params with get method. I have something like this:

    path = 'https://example.com/api';
    const params = new HttpParams();
    params.append('http', 'angular');
    return this.http.get(path, {params: params});

I thought I would have url like:

www.example.com/api?http=angular

but actually when I check that in network tab in chrome, request url is

www.example.com/api

What should I do when I want to have path: www.example.com/api?http=angular And is it possible to check request url of used method without chrome? I mean in service where I use that method?

回答1:

You need to reassign after the append function call. It returns a new HttpParams object.

const params = new HttpParams().append('http', 'angular');

This is the documentation of append. You can see that it returns HttpParams instance

append(param: string, value: string): HttpParams

Construct a new body with an appended value for the given parameter name.

And is it possible to check request url of used method without chrome ?

You can create an HttpInterceptor and see the whole url which will be used in the intercept function implementation.
