要創(chuàng)建Laravel控制器，使用Artisan命令即可。1. 基本控制器：運(yùn)行php artisan make:controller UserController生成空控制器；2. 資源控制器：使用php artisan make:controller PostController --resource創(chuàng)建包含CRUD方法的控制器，并在routes/web.php中注冊Route::resource('posts', PostController::class)；3. API控制器：運(yùn)行php artisan make:controller ApiController --api生成僅含JSON響應(yīng)方法的控制器；最后在路由文件中注冊對應(yīng)路由，如Route::get('/users', [UserController::class, 'index'])；建議遵循命名規(guī)范，保持控制器職責(zé)單一，復(fù)雜邏輯移至服務(wù)類。

Creating a controller in Laravel is straightforward thanks to Laravel's Artisan command-line tool. Here’s how you can do it step by step.

? Using Artisan to Generate a Controller

The easiest way to create a controller is by using the make:controller Artisan command.

php artisan make:controller UserController

This will create a new file UserController.php in the app/Http/Controllers directory.

? Types of Controllers

Depending on your needs, you can generate different types of controllers:

1. Basic Controller

Just a plain controller with no predefined methods.

php artisan make:controller PostController

2. Resource Controller

Creates a controller with CRUD methods (index, create, store, show, edit, update, destroy) for RESTful routes.

php artisan make:controller PostController --resource

Or shorthand:

php artisan make:controller PostController -r

Then, in your routes (e.g., routes/web.php or routes/api.php), use:

use App\Http\Controllers\PostController;

Route::resource('posts', PostController::class);

3. API Resource Controller

If you're building an API and don’t need views (only JSON responses), use:

php artisan make:controller ApiController --api

This generates only index, store, show, update, and destroy methods—ideal for APIs.

? Example: Basic Controller Structure

After running the Artisan command, your controller might look like this:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index()
    {
        return view('user.index');
    }

    public function store(Request $request)
    {
        // Handle form submission
    }

    public function show($id)
    {
        return view('user.show', compact('id'));
    }
}

? Assigning Routes

Don’t forget to register routes in routes/web.php or routes/api.php. For example:

use App\Http\Controllers\UserController;

Route::get('/users', [UserController::class, 'index']);
Route::post('/users', [UserController::class, 'store']);
Route::get('/users/{id}', [UserController::class, 'show']);

? Tips

• Always follow naming conventions: StudlyCase for class names (e.g., ProductController).
• Keep controllers focused—use resource controllers when building CRUD interfaces.
• For complex logic, consider moving business logic to service classes.

That’s it. Basically, one Artisan command sets everything up—you just add your logic.
