您需要在组件中定义一个布尔变量，然后将结果分配给该变量，

hasVipAccess : boolean = false;

if (settings != null && settings.checkSubscriptionForVip === true) {
            this.user.hasVipAccess().then(function(access) {
               this.hasVipAccess = access;               
            });
          } else {
          this.hasVipAccess = access;
 }

但是，如果不需要设置布尔变量，只需返回结果

等效于以下角度2中的代码
