Angularjs工厂注入错误

我正在使用angularJS,当我注射工厂时,我收到错误:

app.js:

angular.module('myapp', [])

myfactory.js:

angular.module('myapp', [])
.factory('httpService', function($http, $timeout) {

});

控制器: test.js:

angular.module('myapp', [])
.controller('test',  function($scope, $timeout, $sce, $http, httpService) {

  $scope.submit = function() {
  }
});

当我添加httpService时,我收到了错误消息。一切似乎都是对的,我甚至在所有项目中都使用这个工厂。的错误:

检查错误中的链接(https://docs.angularjs.org/error/ $ injector / unpr?p0 = httpServiceProvider%20%3C-%20httpService):

您多次创建模块:

angular.module('myapp', [])

你应该做一次。然后在没有[]

的情况下使用
angular.module('myapp').factory ...
angular.module('myapp').controller ...

答案 1 :(得分:3)

出错的原因是因为在创建httpServicecontroller时,您使用了setter angular.module('myapp', [])语法module而不是getter语法。 angular.module('myapp')。 Angular要求我们只定义一次模块,因此随后的重新定义会导致错误。

所以在app.js中,定义module

angular.module('myapp', []) ;

myfactory.js中删除, []

,使用getter语法
angular.module('myapp')
.factory('httpService', function($http, $timeout) {
});

test.js

angular.module('myapp')
.controller('test',  function($scope, $timeout, $sce, $http,  httpService) {

$scope.submit = function() {
}
});

是的,

您正在做的是重新创建应用

您需要做的是定义一次并继续使用该实例

var app = angular.module('myapp', []);

app.factory('httpService', function($http, $timeout) {

});

app.controller('test',  function($scope, $timeout, $sce, $http, httpService) {

  $scope.submit = function() {
  }
});

或者如果您想要检索您的应用,语法是angular.module(' myapp') 这会返回' myapp',但添加[]会告诉angular创建一个应用而不是获取它

代码应如下所示:

angular.module('myapp', [])
.factory('httpService', function($http, $timeout) {

});
.controller('test',  function($scope, $timeout, $sce, $http, httpService) {

  $scope.submit = function() {
  }
});
