read value from Response

[Paperless]

I am trying to call HTTP GET from component on click of button

   clicked(event) {

    let commentOperation:Observable<Response>;

    commentOperation = (this.http.get(this.heroesUrl)

                  .map(this.extractData)

                  .catch(this.handleError));     

    }

//App Server side

 @RequestMapping(value = "/{resource}", method = RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE, produces=MediaType.ALL_VALUE)

public ResponseEntity getTest (@PathVariable String resource, @RequestBody Map<String, Object> id)

{

System.out.println("ResponseEntity\t"+resource+"id"+id);

ResponseEntity<String> rs = new ResponseEntity<String>("Test est"+id, HttpStatus.OK);

return rs;

}

Call is not reaching server.

How to know where it is failing in web client,

Call is not going to handlError.

If I try to console.log (commentOperation ) it prints 3 objects.

Where to look for response?

Hi Paperless,

You need to subscribe to your observable. It only acts once there is a subscriber.

In your controller do something like this:

commentOperation
   .subscribe(result => this.comment) // This will assign the result of the this.extractData function to this.comment.
