Vue 登录页面实现步骤

创建Vue项目

使用Vue CLI或Vite初始化项目：

npm init vue@latest vue-login-demo
cd vue-login-demo
npm install

安装必要依赖

如需要表单验证或UI组件库：

npm install axios vue-router pinia
npm install element-plus  # 示例使用Element UI

登录页面组件

在src/views/LoginView.vue中创建基础登录表单：

<template>
  <div class="login-container">
    <el-form :model="form" :rules="rules" ref="loginForm">
      <el-form-item prop="username">
        <el-input v-model="form.username" placeholder="用户名"/>
      </el-form-item>
      <el-form-item prop="password">
        <el-input v-model="form.password" type="password" placeholder="密码"/>
      </el-form-item>
      <el-button type="primary" @click="handleLogin">登录</el-button>
    </el-form>
  </div>
</template>

<script setup>
import { ref } from 'vue'
import { useRouter } from 'vue-router'
import { ElMessage } from 'element-plus'

const form = ref({
  username: '',
  password: ''
})

const rules = {
  username: [{ required: true, message: '请输入用户名', trigger: 'blur' }],
  password: [{ required: true, message: '请输入密码', trigger: 'blur' }]
}

const router = useRouter()
const handleLogin = async () => {
  try {
    // 替换为实际API调用
    // const res = await axios.post('/api/login', form.value)
    ElMessage.success('登录成功')
    router.push('/dashboard')
  } catch (error) {
    ElMessage.error(error.message)
  }
}
</script>

<style scoped>
.login-container {
  width: 100%;
  max-width: 400px;
  margin: 0 auto;
  padding: 20px;
}
</style>

配置路由

在src/router/index.js中设置路由：

import { createRouter, createWebHistory } from 'vue-router'
import LoginView from '../views/LoginView.vue'

const routes = [
  {
    path: '/login',
    name: 'login',
    component: LoginView
  }
]

const router = createRouter({
  history: createWebHistory(),
  routes
})

export default router

状态管理（可选）

使用Pinia存储登录状态：

// src/stores/auth.js
import { defineStore } from 'pinia'

export const useAuthStore = defineStore('auth', {
  state: () => ({
    token: localStorage.getItem('token') || null
  }),
  actions: {
    setToken(token) {
      this.token = token
      localStorage.setItem('token', token)
    }
  }
})

表单验证增强

可引入VeeValidate进行复杂验证：

npm install @vee-validate/rules @vee-validate/yup

示例验证规则：

import { useField, useForm } from 'vee-validate'
import * as yup from 'yup'

const { handleSubmit } = useForm({
  validationSchema: yup.object({
    username: yup.string().required().min(3),
    password: yup.string().required().min(6)
  })
})
