Composer >= 2.0
NPM >= 6.0
MySQL >= 5.7

2.2 开发工具推荐

2.3 环境配置示例

# 安装PHP扩展
sudo apt install php-mbstring php-xml php-curl

# 配置PHP.ini
memory_limit = 256M
upload_max_filesize = 50M
post_max_size = 50M

3. 项目初始化

3.1 创建Laravel项目

composer create-project --prefer-dist laravel/laravel laravel-vue-spa
cd laravel-vue-spa

3.2 前端依赖安装

npm install vue@next vue-router@4 vue-loader@next @vue/compiler-sfc
npm install axios vue-axios @inertiajs/inertia @inertiajs/inertia-vue3

3.3 目录结构调整

/resources
  /js
    /components
    /layouts
    /pages
    /router
    /store
    app.js
    bootstrap.js

4. 前端架构搭建

4.1 初始化Vue应用

// resources/js/app.js
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'

createApp(App)
  .use(router)
  .use(store)
  .mount('#app')

4.2 主组件结构

<!-- resources/js/App.vue -->
<template>
  <div id="app">
    <nav-bar />
    <router-view />
    <app-footer />
  </div>
</template>

<script>
import NavBar from './components/NavBar.vue'
import AppFooter from './components/AppFooter.vue'

export default {
  components: { NavBar, AppFooter }
}
</script>

4.3 配置Webpack.mix.js

const mix = require('laravel-mix')

mix.js('resources/js/app.js', 'public/js')
   .vue()
   .sass('resources/sass/app.scss', 'public/css')
   .version()

5. 后端API开发

5.1 API路由配置

// routes/api.php
Route::group(['prefix' => 'v1'], function() {
    Route::apiResource('posts', 'App\Http\Controllers\API\PostController');
    Route::post('login', 'AuthController@login');
    Route::post('register', 'AuthController@register');
});

5.2 控制器示例

namespace App\Http\Controllers\API;

use App\Http\Controllers\Controller;
use App\Models\Post;
use Illuminate\Http\Request;

class PostController extends Controller
{
    public function index()
    {
        return response()->json([
            'data' => Post::paginate(10)
        ]);
    }
}

5.3 API资源转换

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;

class PostResource extends JsonResource
{
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'title' => $this->title,
            'content' => $this->content,
            'created_at' => $this->created_at->format('Y-m-d H:i:s')
        ];
    }
}

6. 前后端集成

6.1 配置Axios实例

// resources/js/api.js
import axios from 'axios'

const api = axios.create({
  baseURL: '/api/v1',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json'
  }
})

// 请求拦截器
api.interceptors.request.use(config => {
  const token = localStorage.getItem('auth_token')
  if (token) {
    config.headers.Authorization = `Bearer ${token}`
  }
  return config
})

export default api

6.2 API调用示例

// resources/js/store/modules/posts.js
import api from '../../api'

const actions = {
  async fetchPosts({ commit }, page = 1) {
    try {
      const response = await api.get(`/posts?page=${page}`)
      commit('SET_POSTS', response.data.data)
    } catch (error) {
      console.error(error)
    }
  }
}

7. SPA路由配置

7.1 Vue Router配置

// resources/js/router/index.js
import { createRouter, createWebHistory } from 'vue-router'
import Home from '../pages/Home.vue'
import PostList from '../pages/posts/List.vue'

const routes = [
  { path: '/', component: Home },
  { path: '/posts', component: PostList },
  { path: '/:pathMatch(.*)*', redirect: '/' }
]

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

export default router

7.2 Laravel路由回退

// routes/web.php
Route::get('/{any}', function () {
    return view('app');
})->where('any', '.*');

8. 状态管理

8.1 Vuex Store配置

// resources/js/store/index.js
import { createStore } from 'vuex'
import posts from './modules/posts'
import auth from './modules/auth'

export default createStore({
  modules: { posts, auth }
})

8.2 状态管理示例

// resources/js/store/modules/auth.js
const state = {
  user: null,
  token: localStorage.getItem('auth_token') || null
}

const mutations = {
  SET_USER(state, user) {
    state.user = user
  },
  SET_TOKEN(state, token) {
    state.token = token
    localStorage.setItem('auth_token', token)
  }
}

export default { state, mutations }

9. 认证系统实现

9.1 Laravel Sanctum配置

composer require laravel/sanctum
php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"
php artisan migrate

9.2 登录逻辑实现

// app/Http/Controllers/AuthController.php
public function login(Request $request)
{
    $credentials = $request->only('email', 'password');
    
    if (Auth::attempt($credentials)) {
        $token = $request->user()->createToken('auth_token')->plainTextToken;
        return response()->json(['token' => $token]);
    }
    
    return response()->json(['error' => 'Unauthorized'], 401);
}

9.3 前端登录组件

<template>
  <form @submit.prevent="handleLogin">
    <input v-model="form.email" type="email">
    <input v-model="form.password" type="password">
    <button type="submit">Login</button>
  </form>
</template>

<script>
import { reactive } from 'vue'
import { useStore } from 'vuex'
import { useRouter } from 'vue-router'

export default {
  setup() {
    const store = useStore()
    const router = useRouter()
    const form = reactive({
      email: '',
      password: ''
    })
    
    const handleLogin = async () => {
      try {
        const response = await api.post('/login', form)
        store.commit('auth/SET_TOKEN', response.data.token)
        router.push('/dashboard')
      } catch (error) {
        console.error(error)
      }
    }
    
    return { form, handleLogin }
  }
}
</script>

10. 性能优化

10.1 代码分割

// 动态导入组件
const PostDetail = () => import('../pages/posts/Detail.vue')

10.2 缓存策略

// 缓存API响应
Route::get('/posts', function() {
    return Cache::remember('posts', 60, function() {
        return Post::all();
    });
});

10.3 图片懒加载

<img v-lazy="imageUrl" alt="description">

11. 部署上线

11.1 生产环境构建

npm run production
php artisan config:cache
php artisan route:cache

11.2 Nginx配置示例

server {
    listen 80;
    server_name yourdomain.com;
    root /var/www/laravel-vue-spa/public;
    
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }
    
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
    }
}

12. 常见问题

12.1 CORS问题解决

// 安装CORS包
composer require fruitcake/laravel-cors

// config/cors.php
'paths' => ['api/*'],
'allowed_methods' => ['*'],
'allowed_origins' => ['*'],

12.2 CSRF保护

// 在app.js中
axios.defaults.withCredentials = true;

12.3 404处理

// Vue Router中
router.beforeEach((to, from, next) => {
  if (to.matched.length === 0) {
    next('/404')
  } else {
    next()
  }
})
