typeerror 无法读取未定义的 Angular js df 的属性“then”

Question

谁能帮我解决这个问题 错误 - typeerror 无法读取未定义 Angular js 的属性 'then'

当我向 db 插入数据时，我使用 angular js 和 asp.net mvc 开发 Web 应用程序（'typeerror cannot read property 'then' of undefined Angular js'）这个错误引发并且数据客户数据不是传递给 .net 代码。任何人都可以帮助解决这个问题。我是 Angular js 的新手

var app = angular.module('adminmdl', []);
app.controller('admincontroller', function ($scope, AdminService) {
    $scope.Action = 'Add';
    $scope.AddCustomerDetails = function () {
        var customer = {
            cus_code: $scope.Customercode,
            cus_name: $scope.Customername
        }

        if($scope.Action =='Add'){
            AdminService.AddCustomer(customer).then(function (customer) {
                $scope.msg = "Customer Adding Successfully";
            });

        }

    }
})

.factory('AdminService', function ($http) {
    var fact = {};
    fact.AddCustomer = function (customer) {

        $http({
            url:'/Admin/AddCutomer',
            method:'POST',
            type:JSON.stringify(customer),
            dataType:'json'
        });

    }
    return fact;


})


public void AddCutomer(Customer customer) {

            if (customer != null) {

                te.Customers.Add(customer);
                te.SaveChanges();

            }

        }

添加返回到$http 调用。现在你没有从那里返回任何东西。

.factory('AdminService', function ($http) {
    var fact = {};
    fact.AddCustomer = function (customer) {

       return $http({
            url:'/Admin/AddCutomer',
            method:'POST',
            type:JSON.stringify(customer),
            dataType:'json'
        });

    }
    return fact;

})
