Angular 4 HttpClient Query Parameters

Question

I have been looking for a way to pass query paramters into an API call with the new HttpClientModule's HttpClient and have yet to find a solution. With the old Http module you would write something like this.

getNamespaceLogs(logNamespace) {

    // Setup log namespace query parameter
    let params = new URLSearchParams();
    params.set('logNamespace', logNamespace);

    this._Http.get(`${API_URL}/api/v1/data/logs`, { search: params })
}

This would result in an API call to the following URL:

localhost:3001/api/v1/data/logs?logNamespace=somelogsnamespace

However, the new HttpClient get() method doesn't have a search property, so I am wondering where to pass in the query parameters?

If you have an object that can be converted to {key: 'stringValue'} pairs, you can use this shortcut to convert it:

this._Http.get(myUrlString, {params: {...myParamsObject}});

I just love the spread syntax!
