Question

我是角色新手，在尝试从rails后端检索博客帖子列表时遇到此异常。任何人都可以帮助我，我无法找到这个问题的确切解决方案。

Error: [$injector:unpr] Unknown provider: PostProvider <- Post
http://errors.angularjs.org/1.2.22/$injector/unpr?p0=PostProvider%20%3C-%20Post

var myApp = angular.module（＆＃39; Emangu＆＃39;，[＆＃39; ngRoute＆＃39;，＆＃39; ngResource＆＃39;]）;

//Routes 

myApp.config([
  '$routeProvider', '$locationProvider', function ($routeProvider, $locationProvider) {
    $routeProvider.when('/blog', {
      templateUrl: '/templates/posts/index.html',
      controller: 'PostListCtr'
    });
  }
]);

//Controllers

myApp.controller("PostListCtr", ['$scope', '$http', '$resource', 'Posts', 'Post', '$location', function ($scope, $http, $resource, Posts, Post, $location) {

    alert("hello");
    $scope.posts = Posts.query();
    $scope.deletePost = function (Post) {
        if (confirm("Are you sure you want to delete this Post?")) {
            Post.delete({ id: Post }, function () {
                $scope.posts = Posts.list();
                $location.path('/');
            });
        }
    };
}]);

//resources

myApp.factory('Posts', ['$resource', function ($resource) {
  return $resource('/posts.json', {}, {
    query: { method: 'GET', isArray: true },
    create: { method: 'POST' }
  })
}]);

Answer 1

添加Post工厂（服务）或将其从PostListCtr依赖项中删除
