《Lumen与Laravel》

在现代Web开发中，选择合适的框架对于构建高效、可维护的应用程序至关重要。Lumen和Laravel都是基于PHP的优秀框架，它们源自同一个开发者Taylor Otwell，并且共享许多特性。如果您正在寻找一个轻量级且快速的API开发解决方案，Lumen可能是您的；而如果需要一个功能齐全的企业级应用框架，Laravel则更为合适。

一、解决方案简述

当面临构建不同规模和复杂度的应用时，我们可以根据具体需求来选择Lumen或Laravel。例如，对于小型项目或者专注于API服务的项目，使用Lumen可以减少不必要的加载项，提高性能。而对于大型项目，特别是涉及到复杂的业务逻辑、用户认证授权、队列任务等场景时，Laravel提供了更全面的功能支持。

二、解决特定问题示例 - 用户注册与登录

1. 在Lumen中实现

创建路由

php // routes/web.php $app->post('/register', 'AuthController@register'); $app->post('/login', 'AuthController@login');

创建控制器

php
<?php
namespace AppHttpControllers;</p>

<p>use IlluminateHttpRequest;
use AppUser;</p>

<p>class AuthController extends Controller
{
    public function register(Request $request)
    {
        $validatedData = $request->validate([
            'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6'
        ]);</p>

<pre><code>    $user = User::create([
        'name' => $validatedData['name'],
        'email' => $validatedData['email'],
        'password' => bcrypt($validatedData['password'])
    ]);

    return response()->json(['message' => 'User registered successfully'], 201);
}

public function login(Request $request)
{
    $credentials = $request->only('email', 'password');

    if (auth()->attempt($credentials)) {
        $token = auth()->user()->createToken('MyApp')->accessToken;
        return response()->json(['token' => $token], 200);
    } else {
        return response()->json(['error' => 'Unauthorized'], 401);
    }
}

}

2. 在Laravel中实现

定义路由

php // routes/api.php Route::post('/register', [RegisterController::class, 'register']); Route::post('/login', [LoginController::class, 'login']);

创建控制器（这里假设已经使用`php artisan make:auth`生成了相关文件）

php
<?php
namespace AppHttpControllersApi;</p>

<p>use IlluminateHttpRequest;
use AppHttpControllersController;
use AppModelsUser;</p>

<p>class RegisterController extends Controller
{
    public function register(Request $request)
    {
        $validatedData = $request->validate([
            'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6'
        ]);</p>

<pre><code>    $user = User::create([
        'name' => $validatedData['name'],
        'email' => $validatedData['email'],
        'password' => bcrypt($validatedData['password'])
    ]);

    return response()->json(['message' => 'User registered successfully'], 201);
}

}

class LoginController extends Controller
{
public function login(Request $request)
{
$credentials = $request->only('email', 'password');

    if (Auth::attempt($credentials)) {
        $user = Auth::user();
        $tokenResult = $user->createToken('Personal Access Token');
        $token = $tokenResult->token;

        return response()->json([
            'access_token' => $tokenResult->accessToken,
            'token_type' => 'Bearer',
            'expires_at' => Carbon::parse(
                $token->expires_at
            )->toDateTimeString()
        ]);
    } else {
        return response()->json(['error' =>'Unauthorized'], 401);
    }
}

}
