{

  // 登录
  path:'/login',
  component: resolve => require(['@/app/Page/login/login.vue'], resolve),
  meta: {title: '登录',wxAuth: true},
  beforeEnter (to, from, next) {
    if (auth.loggedIn()) {
      next('/home')
    } else {
      next()
    }
  }
},
如上面是js文件中的一段代码，我想在if(auth.loggedIn()){}里面调用在vue里面的methods中创建的这个方法
 getLocation() {
  return this.$store.dispatch("get", {
    uri: consts.PREFIX + "/city/open/location"
  });
},
该怎么实现
