setInterval and update data

Question

How i can update my API (get) with this function setInterval()

I have this this get func.:

getServices(){
    return this._http.get(this._url)
                    .map(res => res.json());
}

And i would to refresh my data (get json data) every 1 second

I found this example, but this function only show logs every one second, and how update my API with get?

 setInterval(function (getServices) {
             console.log("Test")
         }, 1000)

Please provide more information. To me it's entirely unclear what the desired behavior should be. — Günter Zöchbauer, Jul 26 '16 at 13:34
What does "How i can update my API" mean. I don't get what you try to accomplish. — Günter Zöchbauer, Jul 26 '16 at 13:59

@Günter Zöchbauer i would refresh data on the page, but not reload page. my data is json from gerServices() — Eduard Arevshatyan, Jul 26 '16 at 14:22
This is not enough information. I'd suggest you create a Plunker. — Günter Zöchbauer, Jul 26 '16 at 14:26

Should probably be something like:

setInterval(() => {
    this. getServices();
    console.log("Test")
}, 1000);

But as your question is not very clear, it's hard to know for sure.

I guess you mean that you have a function getServices which you want to call every second and do something with the result.

This is how you can do this:

setInterval(() => {
    let result = getServices();
    console.log(result);
}, 1000)

Playground with working example - Run and open console (F12), you will see data is being added to console every second.
