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="myForm" :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" />

          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"

        <span class="show-pwd" @click="showPwd">
          <svg-icon :icon-class="passwordType === 'password' ? 'eye' : 'eye-open'" />

      </el-form-item>

      <el-button :loading="loading" type="primary" style="width:100%;margin-bottom:30px;" @click="handleLogin">登 录</el-button>
    </el-form>

      loading: false,
      passwordType: 'password',
      redirect: '',
    })

    const myForm = ref(null)

    const showPwd = () => {

        data.passwordType = 'text'
      } else {

          store.dispatch('user/login', data.loginForm).then(() => {
            router.push({
              path: '/'
            })
          })
        }
