如何知道Vue.js中路由重定向的来源？

// 定义路由
const routes = [
  {
    path: '/source',
    name: 'source',
    component: SourceComponent,
    meta: { redirectFrom: 'target' } // 设置来源路由的名称
  },
  {
    path: '/target',
    name: 'target',
    component: TargetComponent
  }
];

// 创建路由实例
const router = new VueRouter({
  routes
});

// 在目标路由组件中获取来源路由信息
const TargetComponent = {
  created() {
    const redirectFrom = this.$route.meta.redirectFrom;
    console.log('来源路由：', redirectFrom);
  }
};
