我收到了臭名昭著的未知提供者错误,并在这里查看了所有可能的答案,但我认为我遗漏了一些东西:
应用程序.js
var myApp = angular.module('myApp', [
'ngResource',
'myAppControllers',
'myAppServices',
'myAppFilters'
]).config([
'$locationProvider',
function(
$locationProvider) {
$locationProvider.html5Mode({
enabled: true,
requireBase: false,
rewriteLinks: false
});
}]);
var myAppControllers = angular.module('myAppControllers', []);
var myAppServices = angular.module('myAppServices', []);
var myAppFilters = angular.module('myAppFilters', []);
项目.js
myAppServices.factory('Item',
function($resource) {
return $resource('/api/items/:id');
});
项目服务.js (1)
myAppServices.factory('itemService',
function($q,
$http,
Item) {
return {
delete: function(id){
// Item, $q and $http are undefined here
return Item.delete({id: id}).$promise;
}
};
});
替代ItemService.js (2)
myAppServices.factory('itemService', [
'$q',
'$http',
'Item', // If I don't inject it here I can use this service with $q and $http
function($q,
$http,
Item) {
return {
delete: function(id){
return Item.delete(id).$promise;
}
};
}]);
在我的控制器中:
myAppControllers.controller('ItemsCtrl', [
'$scope',
'itemService',
function(
$scope,
itemService) {
var ctrl = this;
ctrl.ItemService = ItemService;
ctrl.deleteItem = function(id){
ctrl.itemService.delete(id)
.then(function(response){
console.log(response);
}, function (error) {
console.log(error);
});
};
}]);
因此,如果我在(1)中尝试,我会得到 undefined.delete is not a function in
itemService
。如果我在(2)中尝试,应用程序无法加载:
Unknown provider: ItemProvider <- Item <- itemService
那么我做错了什么?
