javascript - 路由时无法检索组件模板

Question

我正在使用Vuejs。这是主要的js:

import Vue from 'vue'
import App from './App.vue'
import router from './router'

Vue.config.productionTip = false;


new Vue({
  render: h => h(App),
  router
}).$mount('#app')

这是路由器:

import Vue from 'vue';
import VueRouter from 'vue-router';
import ControlExcel from './components/ControlExcel';
import Login from "./components/Login";
import blog from './components/blog';
import file from './components/file';


Vue.use(VueRouter);

let routes = [
    {
        path: '/control-excel',
        name: 'ControlExcel',
        component: ControlExcel
    }
    ,
    {
        path: '/loginn',
        component: Login
    }
    ,
    {
        path: '/blog',
        name: 'blog',
        component: blog
    }
    ,
    {
        path: '/file',
        name: 'file',
        component: file
    },


];

export default new VueRouter({
    mode: 'history',
    base: "",
    routes
})

这个应用程序vue:

<template>
  <div id="app">
<!--    <img alt="Vue logo" src="./assets/logo.png">-->
<!--    <HelloWorld msg="Welcome to Your Vue.js App"/>-->

<!--    <ControlExcel />-->

<!--      <component v-bind:is="component" />-->
<span>abcd</span>




      <li class="nav-item">
          <router-link class="nav-link" to="/control-excel">exce</router-link>
      </li>
      <li class="nav-item">
          <router-link class="nav-link" to="/loginn">loginn</router-link>
      </li>

      <li class="nav-item">
          <router-link class="nav-link" to="/blog">blog</router-link>
      </li>

      <li class="nav-item">
          <router-link class="nav-link" to="/file">file</router-link>
      </li>

  </div>
</template>

<script>
// import HelloWorld from './components/HelloWorld.vue'
// import Login from './components/Login.vue'
// import ControlExcel from "./components/ControlExcel";
// import Login from "./components/Login";
import file from './components/file';
import Vue from 'vue';

Vue.component('file',file);

// import DownloadExcel from './components/DownloadExcel'

export default {
  name: 'app',
  components: {
      // Login,
      // ControlExcel,

  }
  ,
    data() {
        return {
            // component: "Login"
        }
    }
}
</script>

在 localhost:8080，我看到那些:

abcd
exce
loginn
blog
file

当我单击其中任何一个时，URL 会发生变化。例如 http://localhost:8080/file对于文件，但它不带组件。

例如文件:

  {
        path: '/file',
        name: 'file',
        component: file
    },

该组件file.vue

<template>
    <div class="blog">
        <h1>fasfsasd</h1>
    </div>
</template>
<script>
    export default{
        name:'file'
        }

</script>
<style scoped>

</style>

这是目录:

src 
-components
--blog.vue
--ControlExcel.vue
--file.vue
--Login.vue
router.js
main.js
App.vue

为什么不能带模板呢？

有动态组件，但我不想使用它，而且它似乎不是最佳实践，如下所示:

<component v-bind:is=”currentComponent”></component>

你的Vue-Router不会改变主组件，只是将匹配的URL的组件放入 <router-view></router-view> ，你没有。您需要将其添加到您的主要组件中。

例如这样:

<div id="app">
  <span>abcd</span>
  <ul>
      <li class="nav-item">
          <router-link class="nav-link" to="/control-excel">exce</router-link>
      </li>
      <li class="nav-item">
          <router-link class="nav-link" to="/loginn">loginn</router-link>
      </li>

      <li class="nav-item">
          <router-link class="nav-link" to="/blog">blog</router-link>
      </li>

      <li class="nav-item">
          <router-link class="nav-link" to="/file">file</router-link>
      </li>
  </ul>

  <router-view></router-view>

</div>
