### 引入vue-router ###

yarn add vue-router@next

### 添加登录路由 ###

1.  src目录下新建router文件夹
2.  router文件夹下新建index.js

import { createRouter, createWebHistory } from "vue-router";
    
    const routes = [
      {
        path: "/login",
        name: "Login",
        component: () => import("../views/login.vue"),
      },
    
      { path: "/:catchAll(.*)", redirect: "/404", hidden: true },
    ];
    
    const router = createRouter({
      history: createWebHistory(), //history模式使用HTML5模式
      routes,
    });
    
    export function resetRouter() {
      const newRouter = createRouter({
        history: createWebHistory(),
        routes,
      });
    
      router.matcher = newRouter.matcher; // reset router
    }
    
    // router.beforeEach(async(to, from, next) => {
    
    // })
    
    export default router;

### 修改main.js ###

import { createApp } from "vue";
    import App from "./App.vue";
    import router from "./router";
    import installElementPlus from "./plugins/element";
    
    import "./styles/index.scss";
    
    const app = createApp(App);
    
    installElementPlus(app);
    
    app.use(router).mount("#app");

### 修改App.vue ###

<template>
      <router-view></router-view>
    </template>
    
    <script setup>
    
    // This starter template is using Vue 3 experimental <script setup> SFCs
    // Check out https://github.com/vuejs/rfcs/blob/script-setup-2/active-rfcs/0000-script-setup.md
    </script>
    
    <style>
    
    </style>

### 添加页面 ###

1.  src目录下新建views文件夹用于存放页面组件
2.  views文件夹下新建login.vue

<template>
      <div class="login-container">
        <el-form ref="loginForm" :model="loginForm" :rules="loginRules" class="login-form" auto-complete="on" label-position="left">
    
          <div class="title-container">
            <h3 class="title">后台登录</h3>
          </div>
    
          <el-form-item prop="username">
            <span class="svg-container">
              <svg-icon icon-class="user" />
            </span>
            <el-input
              ref="username"
              v-model="loginForm.username"
              placeholder="Username"
              name="username"
              type="text"
              tabindex="1"
              auto-complete="on"
            />
          </el-form-item>
    
          <el-form-item prop="password">
            <span class="svg-container">
              <svg-icon icon-class="password" />
            </span>
            <el-input
              :key="passwordType"
              ref="password"
              v-model="loginForm.password"
              :type="passwordType"
              placeholder="Password"
              name="password"
              tabindex="2"
              auto-complete="on"
              @keyup.enter.native="handleLogin"
            />
            <span class="show-pwd" @click="showPwd">
              <svg-icon :icon-class="passwordType === 'password' ? 'eye' : 'eye-open'" />
            </span>
          </el-form-item>
    
          <el-button :loading="loading" type="primary" style="width:100%;margin-bottom:30px;" @click.native.prevent="handleLogin">登 录</el-button>
        </el-form>
