        return function *(){

        try {
        var id = id || 0 ;
        console.log("id=",id);
        }
    }
    getUser(1);//There ouput 'id = 0'

    getUser(id){
        var me = this;
        return function *(){

            try {
                var id2 = id || 0 ;
                console.log("id=",id2);
            }
        }
    getUser(1);//There ouput 'id = 1'
