Passing parameter to $scope.id from URL - angularJS

I'm trying to pass a parameter from the URL in the browser to a controller, for example, the 122 should be passed in $scope.id in the controller so the JSON loaded is this http://52.41.65.211:8028/api/v1/categories/122/books.json, not working though, any idea?

URL example http://www.example.com/categories/122

app.js

   ...  
    .when('/categories/:categoryId', {
        controller: 'BookCategoryController',
        templateUrl: 'views/booksincategory.html'
    })
    ...

controller

app.controller('BookCategoryController', ['$scope', 'bookcategories', '$routeParams',  function($scope, bookcategories, $routeParams) {
    bookcategories.getAllBooks($scope.id).then(function(response) {
    $scope.detail = response.data.books[$routeParams.categoryId];
  });
}]);

service

app.service('bookcategories', ['$http', function($http) {
  return {
    getAllBooks: function(id) {
      return $http.get('http://52.41.65.211:8028/api/v1/categories/'+ id + '/books.json')
     }
  }
}]);

booksincategory.html

  <div class="category col" ng-repeat="book in detail">
     <h3 class="title">{{book.title}}</h3>
  </div>

If your URL is http://www.example.com/categories/122 and route params is like

.when('/categories/:categoryId', {
    controller: 'BookCategoryController',
    templateUrl: 'views/booksincategory.html'
})

then you will get the categoryId in the controller as $routeParams.categoryId

Just set $scope.id = $routeParams.categoryId;

just set this in your controller before calling the service. So your controller will be like

app.controller('BookCategoryController', ['$scope', 'bookcategories', '$routeParams',  function($scope, bookcategories, $routeParams) {
    $scope.id = $routeParams.categoryId;
    bookcategories.getAllBooks($scope.id).then(function(response) {
       $scope.detail = response.data.books;
    });
}]);

Just use

$scope.detail = response.data.books;

no need to use $scope.detail = response.data.books[$routeParams.categoryId]; its an incorrect syntax. Hope that will work for you. You have assigned $scope.detail incorrectly in your controller. I dint see any issue in the HTML
