Vue 登录注册实现

创建 Vue 项目

使用 Vue CLI 创建一个新项目：

vue create vue-auth-demo

安装依赖

安装必要的依赖，如 axios 用于 HTTP 请求，vue-router 用于路由管理：

npm install axios vue-router

配置路由

在 src/router/index.js 中配置路由：

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

Vue.use(Router)

const router = new Router({
  routes: [
    { path: '/login', component: Login },
    { path: '/register', component: Register },
    { path: '/', component: Home, meta: { requiresAuth: true } }
  ]
})

export default router

创建登录组件

在 src/views/Login.vue 中实现登录表单：

vue登录注册实现

<template>
  <div>
    <h2>Login</h2>
    <form @submit.prevent="login">
      <input v-model="email" type="email" placeholder="Email" required>
      <input v-model="password" type="password" placeholder="Password" required>
      <button type="submit">Login</button>
    </form>
  </div>
</template>

<script>
export default {
  data() {
    return {
      email: '',
      password: ''
    }
  },
  methods: {
    async login() {
      try {
        const response = await axios.post('/api/login', {
          email: this.email,
          password: this.password
        })
        localStorage.setItem('token', response.data.token)
        this.$router.push('/')
      } catch (error) {
        console.error(error)
      }
    }
  }
}
</script>

创建注册组件

在 src/views/Register.vue 中实现注册表单：

<template>
  <div>
    <h2>Register</h2>
    <form @submit.prevent="register">
      <input v-model="name" type="text" placeholder="Name" required>
      <input v-model="email" type="email" placeholder="Email" required>
      <input v-model="password" type="password" placeholder="Password" required>
      <button type="submit">Register</button>
    </form>
  </div>
</template>

<script>
export default {
  data() {
    return {
      name: '',
      email: '',
      password: ''
    }
  },
  methods: {
    async register() {
      try {
        const response = await axios.post('/api/register', {
          name: this.name,
          email: this.email,
          password: this.password
        })
        localStorage.setItem('token', response.data.token)
        this.$router.push('/')
      } catch (error) {
        console.error(error)
      }
    }
  }
}
</script>

添加路由守卫

在 src/router/index.js 中添加路由守卫以保护需要认证的路由：

vue登录注册实现

router.beforeEach((to, from, next) => {
  if (to.matched.some(record => record.meta.requiresAuth)) {
    if (!localStorage.getItem('token')) {
      next('/login')
    } else {
      next()
    }
  } else {
    next()
  }
})

配置 API 请求

在 src/main.js 中配置 axios 全局设置：

import axios from 'axios'

axios.defaults.baseURL = 'http://your-api-url.com'
axios.interceptors.request.use(config => {
  const token = localStorage.getItem('token')
  if (token) {
    config.headers.Authorization = `Bearer ${token}`
  }
  return config
})

Vue.prototype.$http = axios

创建 Home 组件

在 src/views/Home.vue 中创建受保护的主页：

<template>
  <div>
    <h2>Welcome</h2>
    <button @click="logout">Logout</button>
  </div>
</template>

<script>
export default {
  methods: {
    logout() {
      localStorage.removeItem('token')
      this.$router.push('/login')
    }
  }
}
</script>
