angular.js - The result of AngularJS asynchronous request data is delivered, deferred.promise is unstable

Question

AngularJS After asynchronously requesting data, use deferred.promise to pass the value, but it is very unstable. It is refreshed 10 times and only displayed 2 times.
I don’t know what’s wrong with my code, or if there’s a better way, please enlighten me!

Service file: service.js
<pre>
app.factory('Factory',['$sce','$q','$http',function($sce,$q ,$http){

var _baseUrl="//api.a.com",deferred = $q.defer(),service={};
service.list=function(_params){
    query({item:"/a/index",params:_params}).success(function(data){
        if(data.code==0){
            deferred.resolve(data.data);
        }else{
            alert("Error");
        }
    });
    return deferred.promise;
}
var query=function(rq){
    var item=rq['item'],params=rq['params'];
    return $http({
        method:"POST",
        url:_baseUrl+item,
        params:params,
        headers:{'Content-Type': 'application/x-www-form-urlencoded'}
    }).error(function(data){
        $.notify({message:_ay.system.code.api.error[data.code]},{type:"danger"});
    });
};
return service;

}
</pre>
Controller file: controller.js
<pre>
app.controller('ctrl.detail',['$scope','$ routeParams','Factory',function($scope,$routeParams,Factory){

var _param=$routeParams,_id=_param.g,_token=token;
$scope.d_detail={};
$scope.detail=function(){
    Factory.list({token:_token,device_id:_id}).then(function(data){
        $scope.d_detail=data.row;
    });
};
(init = function(){
    $scope.detail();
})();

}]);
</pre>
Page display
<pre>
<p data-ng-controller="ctrl.detail">

<li data-ng-bind="d_detail.id"></li>
<li data-ng-bind="d_detail.name"></li>

</p>
</pre>

Answer 1

service.list = function (_params) {
    var deferred = $q.defer();
    query({ item: "/a/index", params: _params }).success(function (data) {
        if (data.code == 0) {
            deferred.resolve(data.data);
        } else {
            alert("Error");
        }
    });
    return deferred.promise;
}
