Question

为什么第二个console.log在第一个打印实际数据时给我未定义？如何将promise中收到的数据分配给任何变量，以便能够在没有承诺的情况下使用它？

angular.module('dopasujApp')
    .controller('productLoader', [ '$scope','getProducts',
        function ($scope,getProducts) {
            $scope.recived = {};
            console.log($scope.list);
            function getter() {
                return getProducts(1, 150, 20, 'ASC', 'PRODUCT_ID', 'a').then(function (recived) {
                        $scope.recived = recived;
                        console.log($scope.recived);
                    }
                );
            }

            getter();
            console.log($scope.recived);
        }
]);

这是我的工厂代码：

angular.module('dopasujApp').factory('getProducts', ['$http', function ($http) {
 return function(fit = 1, limit = 150, vendor = 20, sort = 'ASC', orderBy = 'PRODUCT_ID', search='a', size=[], filters={}, attribs=[]) {
     var getProduct = {}, recived = {}, APIurl;
     getProduct.data={};
     getProduct.data.sort=sort;
     getProduct.data.orderBy=orderBy;
     getProduct.data.search=search;
     getProduct.data.filters=filters;
     getProduct.data.filters.ATTRIBS=attribs;
     getProduct.data.filters.SIZE=size;
     recived.list= [];
     recived.count = 0;
     recived.filters = {};
     APIurl = "*******?action=getListing&fit="+fit+"&limit="+limit+"&vendor="+vendor;
     var request = $http({
         method: "POST",
         url: APIurl,
         headers: {
            'Content-Type': 'application/json'
         },
         data: {
            data:  getProduct.data
         }
     });

     var values = request.then(function (response){
         return {
             list: response.data.QUERY,
             count: response.data.COUNT,
             filters: response.data.FILTERS
         };
     });
     return values;
 }
 }]);

因为你的getProducts是一个承诺，甚至很难你的第二个console.log在你的getter（）;之后，在你的promise被解决之前执行console.log，这就是为什么它未定义。

无法从控制器中的工厂接收数据（Angular）
