AngularJs跨域问题

Question

当我尝试使用$http.jsonp获取数据时，数据无法在日志中显示，为什么？

userApp.controller('userCtrl', ['$scope', '$http',  'serverUrl', 'userService', 'loginService', function($scope, $http,serverUrl, userService, loginService) {
    $scope.currentPage = 1;
    $scope.currentCount = 10;
    $scope.perPageOptions = [10, 15, 20, 30, 50];
    $scope.pages = [];

    $http.jsonp(serverUrl + "/admin/login/?adminName=root&password=123123&callback=JSON_CALLBACK").success(function(data) {
        console.log(data); //can't show in the log
    });

    $http.jsonp(serverUrl + "/admin/users?page=" + $scope.currentPage + "&count=" + $scope.currentCount + "&mobile=&userId=0&status=1&callback=JSON_CALLBACK").success(function(data) {
        console.log(data); //can't show in the log
        if (data.code == 0) {
            $scope.items = data.data.users;
            $scope.totalItems = data.data.numTotal;
            $scope.totalPage = Math.ceil(data.data.numTotal / $scope.currentCount);
            for (var i = 1; i < $scope.totalPage + 1; i++) {
                $scope.pages.push(i);
            }
        }
    });
}]);
