{  // 登錄  path:'/login',  component: resolve => require(['@/app/Page/login/login.vue'], resolve),  meta: {title: '登錄',wxAuth: true},  beforeEnter (to, from, next) {    if (auth.loggedIn()) {      next('/home')    } else {      next()    }  }},如上面是js文件中的一段代碼，我想在if(auth.loggedIn()){}里面調用在vue里面的methods中創建的這個方法 getLocation() {  return this.$store.dispatch("get", {    uri: consts.PREFIX + "/city/open/location"  });},該怎么實現
