如何在vue路由器上做动态路由? [英] How to make dynamic routes on the vue router?

问题描述

我的 MainNavBar 组件是这样的:

My MainNavBar component like this :

<template>
  ...
  <v-list-item
    v-for="(item, index) in listMenu"
    :key="index"
    @click="goTo(item)"
  >
    <v-list-item-content>
      <v-list-item-title>{{ item }}</v-list-item-title>
    </v-list-item-content>
  </v-list-item>
  ...
</template>
<script>
  export default {
      ...
      methods: {
        goTo(key) {
          this.$router.push({ name: key });
        },
        ...mapActions("dataStore", ["getMenu"])
      },
      computed: {
        ...mapGetters("dataStore", ["listMenu"])
      }
    };
</script>

listMenu 取自 API.这是一个菜单列表

listMenu taken from API. It is a menu list

我的路由器配置如下:

import Vue from "vue";
import Router from "vue-router";
import Application from "@/pages/Application"
import MainNavbar from "@/layout/MainNavbar";
...
import { APPLICATION_ROUTE as RouteConfig } from "./route-config";

Vue.use(Router);
export default new Router({
  mode: 'history',
  routes: [
    {
      path: "/menu-first",
      name: RouteConfig.APPLICATION_NAME_1.NAME,
      components: { default: Application, header: MainNavbar }
    },
    {
      path: "/menu-two",
      name: RouteConfig.APPLICATION_NAME_2.NAME,
      components: { default: Application, header: MainNavbar }
    },
    ...
  ]
});

我的 RouterConfig 像这样:

export const APPLICATION_ROUTE = {
    APPLICATION_NAME_1: {
        NAME: "menu-first"
    },
    APPLICATION_NAME_2: {
        NAME: "menu-two"
    },
    ...
};

我的应用程序组件是这样的:

And my application component like this :

<template>
  <v-flex xs12>
    <v-card dark color="light-blue darken-4">
      <v-card-title>
        <v-flex xs4>
          <p class="title">Name</p>
          <p class="body-2 margin-sub-text">{{detailMenu.name}}</p>
        </v-flex>
        <v-flex xs4>
          <p class="title">URL</p>
          <p class="body-2 margin-sub-text">{{detailMenu.url}}</p>
        </v-flex>
        <v-flex xs4>
          ...
        </v-flex>
      </v-card-title>
    </v-card>
  </v-flex>
</template>

<script>
import { mapActions, mapState, mapGetters } from "vuex";
export default {
  ..
  created() {
    this.getDetailMenu(this.$route.path);
  },
  computed: mapState({
    data: state => state.dataStore.data,
    ...mapGetters("dataStore", ["detailMenu"])
  }),
  methods: {
    ...mapActions("dataStore", ["getDetailMenu"]),
  },
  watch: {
    $route() {
      this.getDetailMenu(this.$route.path);
    }
  }
};
</script>

从配置路由器来看，我的路由器不是动态的.我想让我的路由器动态.所以路由器配置中的路径取自listMenu (API)

From the configuration router, my router is not dynamic. I want to make my router dynamic. So the path in the router configuration is taken from listMenu (API)

我该怎么做?

推荐答案

我想 getDetailMenu 正在调用 API 方法来获取 listMenu.您可以使用 addRoutes 方法

I suppose getDetailMenu is calling API method to get listMenu. You can create route dynamically using addRoutes method

伪代码

created() {
  this.getDetailMenu(this.$route.path)
    .then((listMenu) => {
      // you need to return listMenu from getDetailMenu
      listMenu.forEach((item, index) => createAndAppendRoute(item, index))
    })
},
methods: {
  createAndAppendRoute: (item, index) => {
    console.log(item, index)
    // Base on your data, you should be able to create router name and path from item and index
    // here is just an example
    let newRoute = {
      path: `/${item}`,
      name: `${item}_${index}`,
      components: { default: Application, header: MainNavbar },
    }

    this.$router.addRoutes([newRoute])
  }
}
