一、效果

注意我这里使用了element组件

二、代码

1、index.js

import Vue from 'vue'
import VueRouter from 'vue-router'
import Login from '../views/homePage/login'
import Register from '../views/homePage/register'
import HomePage from '../views/homePage'
import Library from '../views/library'

Vue.use(VueRouter)

const routes = [
  {
    path: '/library',
    component: Library
  },
  {
    path: '/homePage',
    component: HomePage,
    children: [
      {
        path: '/login',
        component: Login
      },
      {
        path: '/register',
        component: Register
      },
    ],
  },


const router = new VueRouter({
  mode: 'history',
  base: process.env.BASE_URL,
  routes
})

export default router

2、App.vue

<template>
  <div id="app">
    <router-view />
  </div>
</template>

3、首页

通过 components节点，为当前的组件注册私有子组件

import Login from "../homePage/login/index.vue";
import Register from "../homePage/register/index.vue";

<template>
  <el-tabs v-model="activeName" @tab-click="handleClick">
    <el-tab-pane label="用户登录" name="first">
      <my-login />
    </el-tab-pane>
    <el-tab-pane label="用户注册" name="second">
      <my-register />
    </el-tab-pane>
  </el-tabs>
</template>
<script>
import Login from "../homePage/login/index.vue";
import Register from "../homePage/register/index.vue";
export default {
  components: {
    "my-login": Login,
    "my-register": Register,
  },
  data() {
    return {
      activeName: "second",
    };
  },
  methods: {
    handleClick(tab, event) {
      console.log(tab, event);
    },
  },
};
</script>
  

4、登录（注册同理）

<template>
  <div class="login">
    <div class="userName">
      <el-input
        type="text"
        placeholder="请输入用户名"
        v-model="FORM_DATA.userName"
      />
    </div>
    <div class="password">
      <el-input
        type="password"
        placeholder="请输入密码"
        v-model="FORM_DATA.password"
      />
    </div>
    <div class="loginButton">
      <!-- type="primary"设置按钮背景颜色为绿色 
      :plain="true"窗体主体部分背景颜色透明
      -->
      <el-button type="primary" :plain="true" @click="login">登录</el-button>
    </div>
  </div>
</template>

<script>
import request from "@/axios/baseURL";
import router from "@/router";

// 接口数据初始化
const FORM_DATA = {
  userName: "",
  password: "",
};
export default {
  data() {
    return {
      FORM_DATA,
    };
  },
  created() {
    console.log("登录界面");
  },
  methods: {
    login() {
      request.post("/systemUser/login", this.FORM_DATA).then((res) => {
        var code = res.data.code;
        var message = res.data.message;
        this.$message(message);
        if (code == 0) {
          router.push("/library");
        }
        console.log(res);
      });
    },
  },
};
</script>
