javascript - Angular 2: How to access an HTTP response body?

Question

I wrote the following code in Angular 2:

this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10').
      subscribe((res: Response) => {
        console.log(res);
      })

When I print the response I get in console:

I want to have access in the code to body field in the response. The 'body' field starts with an underscore, which means that it's a private field. When I change it to 'console.log(res._body)' I got an error.

Do you know any getter function that can help me here?

Answer 1

Both Request and Response extend Body. To get the contents, use the text() method.

this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10')
    .subscribe(response => console.log(response.text()))

That API was deprecated in Angular 5. The new HttpResponse<T> class instead has a .body() method. With a {responseType: 'text'} that should return a String.
