Response interceptor on resource does not allow me to change data

[honzajde]

query: {
    method: 'GET',
        interceptor: {
        response: function(response) {
            console.debug('Tags: ', response.data.tags);
            response.data = response.data.tags;
            return response;
        }
    }
}

After resource is resolved it should be tags but its data.

I guess, transformResponse should be used for modifying data - but this is not documented.

Correct way to modify response is obviously:

                        isArray:true,
                        transformResponse: function(data, headersGetter){
                            data = angular.fromJson(data);
                            return data.tags;
                        }

It is documented here: http://docs.angularjs.org/api/ng.$http under the section entitled "Transforming Requests and Responses"
I am surprised that your interceptor method did not work, though. What exactly is the object you get passed to your then() function?

[honzajde]

The documentation link points to $http service, while this is using $resource.

@honzajde I knot this post is really old, but I was also looking for a solution and didn't found one on the internet.

In the function you provided, you should be modifying response.resource not the response.data if you want to modify the output (tested in Angular 1.3)

@piteer1 I have the same problem with interceptor. Your solution works but response.resource cannot be replaced. We have to modified the values inside the reference … less handy than transformResponse but with transformResponse i cannot get the status code …

I think it's weird that passing an interceptor into an action on a $resource doesn't let the interceptor intercept requests, only responses.

For example:

var Thing = $resource('/thing/:id',
      {thingId:'@id'},
     {
         foo: {method:'POST', interceptor: myInterceptor}
     }
);

myInterceptor will only intercept the response of Thing.foo(), NOT the request...

I know this issue is closed, but for anyone who search :

To modify the data in a resource interceptor, you need to modify response.data and response.resource. Example of the weird behaviour :

live example with AngularJS 1.2.27 : http://jsfiddle.net/605twneu/2/

Should I open an issue ? What do you think ?

If anyone still search for answer look at this issue #11409, there is detailed discussion about interceptors and why $resource interceptors different from $http.
