Angularjs 在返回承诺时，它给我一个未知的提供程序错误

这是工厂

latModule.factory('latSvc',
[
    "$http", "$scope", "$q",
    function($http, $scope, $q) {
        console.log("Enter latUserReportDateSvc");

        return {
            getPromiseForUserReportDate: function () {
                $scope.userId = "bpx3364";
                var deferred = $q.defer();
                $http.get('/api/UserReportStatusApi', { 'userId': $scope.userId }).then(function(reponse) {
                        deferred.resolve(reponse);
                    },
                    function(error) {
                        deferred.reject(error);
                    });
                return deferred.promise;
            },
            getPromiseForLocation: function () {
                $scope.userId = "bpx3364";
                var deferred = $q.defer();
                $http.get('api/UserAccountApi/', { 'userId': $scope.userId }).then(function (reponse) {
                    deferred.resolve(reponse);
                },
                    function (error) {
                        deferred.reject(error);
                    });
                return deferred.promise;
            },
            getPromiseForErrorSummary: function (userInfoVm) {
                console.log("latErrorSummarySvc getErrorCounts, userInfo: ", userInfoVm);
                $scope.userId = "bpx3364";
                $scope.serviceTypeCode = 4;
                var deferred = $q.defer();
                $http.get('/api/UserReportStatusApi', { 'userId': $scope.userId, 'serviceTypeCode': $scope.serviceTypeCode }).then(function (reponse) {
                    deferred.resolve(reponse);
                },
                    function (error) {
                        deferred.reject(error);
                    });
                return deferred.promise;
            }

        };


    }
]);

这是控制器

latModule.controller("dashboardController",
    ["$scope","latSvc",
function ($scope,latSvc) {
    console.log("enter dashboard controller");

    console.log("scope: ", $scope);

    console.log("homeUserInfo: ", $scope.homeLatUserInfo);


  var dashboardUserReportDate = function() {
        latSvc.getUserReportDateInfo().then(
            function(response) {
                $scope.dashboardUserReportDateData = response;

            }, function(error) {}
        );
    };
    dashboardUserReportDate();
    var dashboardErrorCounts = function() {
        latSvc.getPromiseForErrorSummary($scope.homeLatUserInfo).then(
            function(response) {
                $scope.dashboardErrorCountsData = response;

            },
            function (error) { }
        );
    };
    dashboardErrorCounts();
    var dashboardAtmCount = function() {
        latSvc.getPromiseForLocation().then(
            function(response) {
                $scope.dashboardAtmCountData = response;
            }, function(error) {}
        );
    };

    dashboardAtmCount();
}]);

运行此代码后，我在尝试实现此承诺概念时遇到未知的提供程序错误。因为当我在未解析承诺的情况下通过服务调用时，url被多次命中。

您无法使用/向服务中注入$scope。 但就我所理解的代码而言，您应该可以使用局部变量作为http请求查询参数

Vineet是对的-您应该直接返回$http.get，这已经是一个承诺。

您能准确地告诉我您得到的错误吗？您应该编写代码从facory或service返回承诺。它应该是从工厂返回的$http.get，并在您的控制器中使用返回的承诺。您可以展示您的解决方案的示例吗？
