Angular2 http response body on error

this.http.put(url, data)
    .map(response => response.json())
    .subscribe(
      response => console.log(response),
      error => console.log(error),
    );

On success it outputs the data returned from the API. On error the output is ProgressEvent with status of 0.

How to get the response data from the API when error occurs?

You can check the _body property in response, like:

this.http.put(url, data)
.map(response => {
  if (response['_body']) { // check response here.
    return response.json()
  } else {
    return {} // or return null.
  }
})
.subscribe(
  response => console.log(response),
  error => console.log(error),
);

You can probably try 

this.yourHttpCall().subscribe(
        val => {
            //do something
        },
        err => {
            let error = (() => { try { return JSON.parse(err._body) } catch (something) { return err })()
            console.log(error);
        }

    );

That's kind of a hack around it. Not sure if it works for your endpoint.
