vue3的elementplus登录界面

可以使用Element Plus的Form和Input组件来实现登录界面。具体步骤如下：

1. 在Vue组件中引入Form和Input组件：

<template>
  <el-form>
    <el-form-item label="用户名">
      <el-input v-model="username"></el-input>
    </el-form-item>
    <el-form-item label="密码">
      <el-input type="password" v-model="password"></el-input>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="login">登录</el-button>
    </el-form-item>
  </el-form>
</template>

<script>
import { ElForm, ElFormItem, ElInput, ElButton } from 'element-plus';

export default {
  components: {
    ElForm,
    ElFormItem,
    ElInput,
    ElButton,
  },
  data() {
    return {
      username: '',
      password: '',
    };
  },
  methods: {
    login() {
      // 处理登录逻辑
    },
  },
};
</script>

2. 在Vue组件中处理登录逻辑，可以使用axios发送POST请求到后端接口：

<script>
import axios from 'axios';
import { ElForm, ElFormItem, ElInput, ElButton } from 'element-plus';

export default {
  components: {
    ElForm,
    ElFormItem,
    ElInput,
    ElButton,
  },
  data() {
    return {
      username: '',
      password: '',
    };
  },
  methods: {
    async login() {
      try {
        const response = await axios.post('/api/login', {
          username: this.username,
          password: this.password,
        });
        // 处理登录成功逻辑
      } catch (error) {
        // 处理登录失败逻辑
      }
    },
  },
};
</script>
