angularJS读取响应cookie参数为空

request URL:http://www.test.tst/login
request Method:GET
Status Code:200 OK
request Headersview source
Accept:application/json,text/plain,*/*
Accept-Encoding:gzip,deflate,sdch
Accept-Language:de-DE,de;q=0.8,en-US;q=0.6,en;q=0.4
Connection:keep-alive
Cookie:JSESSIONID=349AD3AC797C6AB28121ADA1766FF4A2
Host:www.test.tst

我这样实现：

$scope.checkToken = function () {
            $http({method: 'GET',url: 'http://www.test.tst/login',params: {'action.code': 'LINK','linkparameter': $rootScope.token}}).
                success(function (data,status,headers,config) {
                    console.log($cookieStore.get('JSESSIONID'));
                }).
                error(function (data,config) {
                    $LOCATIOn.path("/login");
                });
        }

任何人都可以告诉我,为什么$cookieStore.get(‘JSESSIONID’)始终未定义？

cookie域与我的请求来自的域相同.
