要在Laravel中使用策略来限制API速率,可以使用Laravel的中间件功能。以下是一个简单的步骤:
php artisan make:middleware RateLimitMiddleware
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Cache\RateLimiter;
use Illuminate\Http\Request;
class RateLimitMiddleware
{
protected $limiter;
public function __construct(RateLimiter $limiter)
{
$this->limiter = $limiter;
}
public function handle(Request $request, Closure $next)
{
$key = $request->ip();
if ($this->limiter->tooManyAttempts($key, 10)) {
return response('Too Many Attempts.', 429);
}
$this->limiter->hit($key, 1);
return $next($request);
}
}
protected $middlewareGroups = [
'api' => [
\App\Http\Middleware\RateLimitMiddleware::class,
// Other middleware...
],
];
Route::middleware('api')->get('/your-api-endpoint', function () {
// API logic here
});
现在,当用户访问API时,中间件将会限制其请求速率。您可以根据需要调整速率限制逻辑和速率限制值。
