主要内容

本章目标：vue+element-ui完成注册以及登陆

1.效果展示

2.视图页面：views

注册页面效果实现：

<template>
  <div class="login-section">
    <!-- :rules="rules" -->
    <el-form label-position="top" label-width="100px" class="demo-ruleForm" :rules="rules" :model="rulesForm" status-icon ref='ruleForm'>
      <el-form-item label="用户名" prop="name">
        <el-input type="text" v-model="rulesForm.name"></el-input>
      </el-form-item>
      <el-form-item label="密码" prop="password">

路由：index.js

import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
import Store from '@/store'
import {userInfo} from '@/service/api.js'
import Home from '@/views/home/Home.vue'
import Login from '@/views/user-login/index.vue'
const router = new Router({
    mode:"history",
    routes:[
        {
            path:'/',
            name:"Home",
            title:"首页",
            component:Home
        }，
        {
            path:'/login',
            name:"login",
            title:"登录页",
            component:Login,
            meta:{
                login:true
            }
        }
    ]
});
router.beforeEach( async (to,from,next) => {
    const token = localStorage.getItem('token');
    const isLogin = !!token;
    //进入路由的时候，需要向后端发送token，验证是否合法
    const data = await userInfo();
    Store.commit('chageUserInfo',data.data)
   if(to.matched.some(item => item.meta.login)){//需要登录
        if(isLogin){//已经登录的，直接通过
            if(data.error === 400){//后端告诉你，登录不成功
                next({name:'login'});
