$http.get and null responses from endpoints

[JamieMason]

$http.get(endpoint).then(function(response) {
// here...
});

If the response body is {"yum":"dinner"} then response.data is an Object, fine.

If the server response body is null then response.data is a String "null".

Should it not be an actual null, since JSON.parse("null") === null?

Thanks for your time, please address/close as desired.

As part of our effort to clean out old issues, this issue is being automatically closed since it has been inactivite for over two months.

Please try the newest versions of Angular (1.0.8 and 1.2.0-rc.1), and if the issue persists, comment below so we can discuss it.

Thanks!

The issue persists for 1.0.8. The result is just the string "null" and the contentType header is "applcation/json". What I get is the string "null" instead of a null object. If I call angular.fromJson myself, I get the expected null object.

Still experiencing this issue in 1.2.1

Looks like it's not being interpreted as JSON because it doesn't pass the test on https://github.com/angular/angular.js/blob/master/src/ng/http.js#L98 because it doesn't start or end with brackets: {} or []

In the meantime I've added another default transformRequest function that checks for a null response:

angular.module('myApp', []).config(['$httpProvider',
  function($httpProvider) {
    $httpProvider.defaults.transformResponse.push(function(data){
      if (data === "null") {
        data = null;
      }
      return data;
    });
  }
]);

This doesn't take into account any whitespace but it's sufficient for my purposes.

Yes, this is the same as #2973. Closing this one as duplicate of #2973 since there is a PR opened for #2973 already.
