编写登录页面

src/views/Login.vue

<template>
  <div class="login-container">
    <el-form :model="myForm" :rules="myRule"
      status-icon
      ref="myForm" 
      label-position="left" 
      label-width="0px" 
      class="demo-ruleForm login-page">
        <h3 class="title">登录</h3>
        <el-form-item prop="username">
          <el-input type="text" 
              v-model="myForm.username" 
              auto-complete="off" 
              placeholder="用户名"
          />
        </el-form-item>
          <el-form-item prop="password">
            <el-input type="password" 
                v-model="myForm.password" 
                auto-complete="off" 
                placeholder="密码"
            />
          </el-form-item>
        <el-checkbox 
            v-model="checked"
            class="rememberme"
        >记住密码</el-checkbox>
        <el-form-item style="width:100%;">
          <el-button type="primary" style="width:100%;" @click="handleSubmit" :loading="logining">登录</el-button>
        </el-form-item>
    </el-form>
  </div>
</template>

<script>
export default {
  data(){
    return {
      logining: false,
      myForm: {
        username: 'admin',
        password: '123456',
      },
      myRule: {
        username: [{required: true, message: '请输入账号', trigger: 'blur'}],
        password: [{required: true, message: '请输入密码', trigger: 'blur'}]
      },
      checked: false
    }
  },
  methods: {
    handleSubmit () {
      this.$refs.myForm.validate((valid) => {
        if (valid) {
          this.logining = true;
          if (this.myForm.username === 'admin' && this.myForm.password === '123456') {
              this.logining = false;
              sessionStorage.setItem('user', this.myForm.username);
              this.$router.push({path: '/'});
          }else{
            this.logining = false;
            this.$alert('账号或密码错误', '温馨提示', {
                confirmButtonText: '确定'
            })
          }
        }else{
          console.log('error submit!');
          return false;
        }
      })
    }
  }
};
</script>

<style>
.login-container {
  width: 100%;
  height: 100%;
}
.login-page {
  -webkit-border-radius: 5px;
  border-radius: 5px;
  margin: 180px auto;
  width: 350px;
  padding: 35px 35px 15px;
  background: #fff;
  border: 1px solid #eaeaea;
  box-shadow: 0 0 25px #cac6c6;
}
label.el-checkbox.rememberme {
  margin: 0px 0px 15px;
  text-align: left;
}
</style>

增加路由

访问 login 要跳转到登录页面
修改 router/index.js 为

import Vue from 'vue'
import VueRouter from 'vue-router'
import Login from '../views/Login.vue'
import Home from '../views/Home.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'home',
    component: Home
  },
  {
    path: '/login',
    name: 'login',
    component: Login
  }
]

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

export default router

访问 http://127.0.0.1:8080/login 出现登录页面:
