Send data with $http.post() in AngularJs

In AngularJs Controller

....
  var config = {
      headers : {
          'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
      }
  }
  $http.post('http://5.project/posts',{category_id:11},config)
  .then(function(response) {	
      vm.posts = response.data;
  });              

And to receive above category_id in php, we have to use following:

....
$params = json_decode(file_get_contents('php://input'),true);
print_r($params);
