[Progrmming with $http service in Angularjs is not giving desired result]

Following code using $http service in Angularjs is not giving required output:
 

$http({
                url: ' "http://localhost/AdvancersService/AdvancersService.svc/GetDomains" ',
                method: "POST",
                data: { "name": { "SearchText": "Info" } },
                
            })
                    .then(function (response) {
                        // success
                        alert("Success:" + response)
                       
                    },
                    function (response) {
                        // failed
                        
                        alert("Failed" + response)
                    });

please suggest to make code operate, any suggestion will be appreciated.
