Issues arise when utilizing Angular HttpClient params in conjunction with the GET method

Can you help me understand how params work with the get method? I currently have this code snippet:

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

I was expecting the URL to look like this:

www.example.com/api?http=angular

However, when I check the network tab in Chrome, the request URL shows:

www.example.com/api

How can I achieve the desired path: www.example.com/api?http=angular Also, is there a way to check the request URL of the used method without using Chrome? Perhaps within the service where the method is used?

Answer №1

Make sure to reassign the result of the append function call, as it generates a fresh HttpParams object.

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

For more information, refer to the append documentation. It clearly states that it returns a new HttpParams instance

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

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

Is there a way to inspect the request URL of a method being used without using Chrome?

You have the option to create an HttpInterceptor to view the entire URL that will be utilized within the intercept function implementation.
