基于Vue2+ElementUI 用户登录注册、用户管理功能

以下是一个简化的Vue2和ElementUI用户登录、注册和用户管理界面的代码示例：

<template>
  <el-container>
    <el-header>
      <h1>用户管理系统</h1>
    </el-header>
    <el-main>
      <!-- 登录表单 -->
      <el-form v-if="!isLoggedIn" ref="loginForm" :model="loginForm" label-width="80px">
        <el-form-item label="用户名">
          <el-input v-model="loginForm.username" autocomplete="off"></el-input>
        </el-form-item>
        <el-form-item label="密码">
          <el-input type="password" v-model="loginForm.password" autocomplete="off"></el-input>
        </el-form-item>
        <el-form-item>
          <el-button type="primary" @click="login">登录</el-button>
          <el-button @click="goToRegister">注册</el-button>
        </el-form-item>
      </el-form>
      <!-- 注册表单 -->
      <el-form v-if="showRegister" ref="registerForm" :model="registerForm" label-width="80px">
        <el-form-item label="用户名">
          <el-input v-model="registerForm.username" autocomplete="off"></el-input>
        </el-form-item>
        <el-form-item label="密码">
          <el-input type="password" v-model="registerForm.password" autocomplete="off"></el-input>
        </el-form-item>
        <el-form-item label="确认密码">
          <el-input type="password" v-model="registerForm.confirmPassword" autocomplete="off"></el-input>
        </el-form-item>
        <el-form-item>
          <el-button type="primary" @click="register">注册</el-button>
          <el-button @click="goToLogin">返回登录</el-button>
        </el-form-item>
      </el-form>
    </el-main>
  </el-container>
</template>
 
<script>
export default {
  data() {
    return {
      isLoggedIn: false, // 用户是否登录
      showRegister: false, // 是否显示注册表单
      loginForm: {
        username: '',
        password: ''
      },
      registerForm: {
        username: '',
        password: '',
        confirmPassword: ''
      }
    };
  },
  methods: {
    login() {
      // 登录逻辑
      this.isLoggedIn = true;
    },
    goToLogin() {
      this.showRegister = false;
    },
    goToRegister() {
      this.showRegister = true;
    },
    register() {
      // 注册逻辑
      this.$message.success('注册成功，请登录！');
      this.showRegister = f
