*当我转到Url:localhost:3000/products时，它显示一个空白页面。我在application.js中添加了//=需要angularjs导轨。我是新来的棱角分明的js。请帮帮我。*

您只需为视图提供如下路径：

var myApp = angular.module('myapplication', ['ngRoute', 'ngResource']); 
//Factory
myApp.factory('Products', ['$resource',function($resource){
  return $resource('/products.json', {},{
    query: { method: 'GET', isArray: true },
    create: { method: 'POST' }
  })
}]);
myApp.factory('Product', ['$resource', function($resource){
  return $resource('/products/:id.json', {}, {
    show: { method: 'GET' },
    update: { method: 'PUT', params: {id: '@id'} },
    delete: { method: 'DELETE', params: {id: '@id'} }
  });
}]);
//Controller
myApp.controller("ProductListCtr", ['$scope', '$http', '$resource', 'Products', 'Product', '$location', function($scope, $http, $resource, Products, Product, $location) {
  $scope.products = Products.query();
  $scope.deleteProduct = function (productId) {
    if (confirm("Are you sure you want to delete this product?")){
      Product.delete({ id: productId }, function(){
        $scope.products = Products.query();
        $location.path('/#/products');
      });
    }
  };
}]);
myApp.controller("ProductUpdateCtr", ['$scope', '$resource', 'Product', '$location', '$routeParams', function($scope, $resource, Product, $location, $routeParams) {
  $scope.product = Product.get({id: $routeParams.id})
  console.log(Product.get({id: $routeParams.id}));
  $scope.update = function(){
    if ($scope.productForm.$valid){
      Product.update({id: $scope.product.id},{product: $scope.product},function(){
        $location.path('/products');
      }, function(error) {
        console.log(error)
      });
    }
  };
}]);
myApp.controller("ProductAddCtr", ['$scope', '$resource', 'Products', '$location', function($scope, $resource, Products, $location) {
  $scope.product = {name}
  $scope.save = function () {
    if ($scope.productForm.$valid){
      debugger
      Products.create({product: $scope.product}, function(){
        $location.path('/products')
      }, function(error){
        console.log(error)
      });
    }
  }
}]);
