Question

我在注册控制器中的响应有问题。由于某种原因，即使用户保存到数据库，结果也总是注册失败。为什么会这样呢？我对棱镜有点新鲜 - 春天并不明白为什么会这样？

user.service.js

(function () {
    'use strict';

    angular
        .module('app')
        .factory('UserService', UserService);

    UserService.$inject = ['$http'];
    function UserService($http) {
        var service = {};

        service.Create = Create;


        return service;

        function Create(user) {

            console.log(user.password)
            console.log(user.lastName)
            console.log(user.email)
            console.log(user.firstName)
            console.log(user.customfield)

            return $http.post('/api/register', user)
        }

})();

并注册。控制器

(function () {
    'use strict';

    angular
        .module('app')
        .controller('RegisterController', RegisterController);

    RegisterController.$inject = ['UserService', '$location', '$rootScope' ];
    function RegisterController(UserService, $location, $rootScope) {
        var vm = this;

        vm.register = register;

        function register() {
            vm.dataLoading = true;
            UserService.Create(vm.user)
                .then(function (response) {
                    if (response.success) {

                        console.log("register Succeed")

                        //FlashService.Success('Registration successful', true);
                        $location.path('/home');

                    } else {

                        console.log("register Failed")
                        vm.dataLoading = false;
                    }
                });
        }
    }

})();

Answer 1

根据the documentation：

响应对象具有以下属性：


data - {string | Object} - 使用转换函数转换的响应体。

status - {number} - 响应的HTTP状态代码。

headers - {function（[headerName]）} - Header getter function。

config - {Object} - 用于生成请求的配置对象。

statusText - {string} - 响应的HTTP状态文本。

您正在测试response.success，这不是文档所说的属性。请改为status。

200到299之间的响应状态代码被视为成功状态，将导致调用成功回调。

Answer 2

至于角度承诺成功的测试，您不需要检查if语句。 promise的then函数有参数（函数），第一个用于调用成功，第二个用于失败，如：

 UserService.Create(vm.user)
    .then(function(response) {
    // this callback will be called asynchronously
    // when the response is available, i.e. success
  }, function(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

Angularjs给出了错误的回应
