How do I POST JSON in Angular 2?

Question

I don\'t understand what I am doing wrong, my server returns \"undefined\" when I try to get the json.

POST(url, data) {
        var headers = new Headers(),         


        

Answer 1

You need to stringify the payload

var requestoptions = new RequestOptions({
            method: RequestMethod.Post,
            url: this.apiURL + url,
            headers: headers,
            body: JSON.stringify(data)
        })
