I use service like this :
province(){
        return this.$http({
            method : "POST",
            url : "http://192.168.1.38:3000/provinces/_search"
        });
    };
and in controller get data like this :
comboInit(){
        /*Province*/
        this.initInfo.province().then(
            /*success*/ (result) => {
                console.log(result);
                this.province=result.data;
            },
            /*error*/(err) => {
                console.log(err);
            }
        );
    }
but I want call province() method like this
this.province=this.initInfo.province()
I want this.initInfo.province()  method without .then() or success() in controller
