Question

我正在调用httpService以发布数据并希望显示消息，例如，如果发生错误。

(function () {
'use strict';

angular.module("adminSetup").controller("AccountController", ["$scope", "$location", "httpService", AccountController]);

function AccountController($scope, $location, httpService) {
    $scope.message = "";
    $scope.error = false;
    $scope.user = {
        username: '',
        password: '',
        firstname: '',
        lastname: '',
        email: '',
        city: ''
    }
    $scope.submitUser = function () {
        httpService.registerUser($scope.user,
            function (data) {
                $scope.message = data;
            },
            function (error)
            {
                $scope.message = error;
            });;
    }
}
})();

服务看起来像这样

(function () {
"use strict"
angular.module("common.services").factory("httpService", ["$q", "$http", "appSettings", userAccountHttp])


function userAccountHttp($q, $http, appSettings) {
    var deferred = $q.defer();
    var registerUser = function (user) {
        $http({
            url: appSettings.serverPath + "Account/Register/",
            method: "POST",
            data: user
        }).then(function (data) {
            return deferred.resolve("Success");
        },
        function (response) {
            return deferred.reject(response.data.exceptionMessage);
        })
    }
    return {
        registerUser: registerUser
    };
}

}）（）;

目前，服务未将Http Status消息返回给AccountController。如何将状态“返回”到控制器

Answer 1

您不需要对承诺建立承诺。这样做：

(function () {
"use strict"
angular.module("common.services").factory("httpService", ["$http", "appSettings", userAccountHttp])


function userAccountHttp($http, appSettings) {
    var registerUser = function (user) {
        return $http({
            url: appSettings.serverPath + "Account/Register/",
            method: "POST",
            data: user
        });
    }
    return {
        registerUser: registerUser
    };
});

我认为这里的问题是你没有回复承诺，你也可以看看this

(function () {
    "use strict"
    angular.module("common.services").factory("httpService", ["$q", "$http", "appSettings", userAccountHttp])


    function userAccountHttp($q, $http, appSettings) {
        var deferred = $q.defer();
        var registerUser = function (user) {
            $http({
                url: appSettings.serverPath + "Account/Register/",
                method: "POST",
                data: user
            }).then(function (data) {
                deferred.resolve("Success");
            },
                function (response) {
                    deferred.reject(response.data.exceptionMessage);
                })

            return deferred.promise;
        }
        return {
            registerUser: registerUser
        };
    }
})();
