        if (!valid) return;
        // const {data: res} = await this.$http.post('login', this.loginForm);

<template>
    <div class="login-wrap" style="background-color: rgb(243,243,243);height: 93.68vh;background-image: url(https://ts1.cn.mm.bing.net/th/id/R-C.f878c96c4179c501a6081ac25291be12?rik=N5jjWCVkYF1qTA&riu=http%3a%2f%2fimg95.699pic.com%2fphoto%2f40129%2f2839.jpg_wh300.jpg!%2ffh%2f300%2fquality%2f90&ehk=dcEzH%2b5aANDDgaScjN2wiRQ8feXvQvU6bSS4hZrmVNM%3d&risl=&pid=ImgRaw&r=0&sres=1&sresct=1
);background-size: 1880px 1100px">
      <el-form class="login-container">
        <h1 class="title">用户注册</h1>
        <el-form-item>
          <el-input type="text" placeholder="用户账号" v-model="username" autocomplete="off"></el-input>

          <el-button type="primary" @click="toLogin" style="width: 48%;">返回登录</el-button>
        </el-form-item>
      </el-form>
    </div>
  </template>
   
  <script>
    export default {
      name: 'Login',
      data: function() {
        return {
          username: '',
          password: '',
          password1:''
        }
      },
      methods: {
        doRegister:function(){
   
        },
        toLogin:function(){
          this.$router.push('/');
        }
      }
    }
  </script>
   
  <style>
   
   
    .login-container {

      margin: 0px auto;
      width: 350px;
      padding: 30px 35px 15px 35px;

      margin: 0px auto 40px auto;
      text-align: center;
      color: #505458;
    }
  </style>

三、配置路由

在router的index.js中写路由配置

import Vue from 'vue'
import VueRouter from 'vue-router'

Vue.use(VueRouter)

const routes = [
    {
        path: '/login',
        name:'Login',
        component:()=>import('../components/Login')
    },
    {
        path:'/',
        redirect:'/login'
    },
    {
        path:'/register',
        name:'Register',
        component:()=>import('../components/Register')
    }

    ]

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

export default router
