In my Laravel project, I need to throw an error or exception manually. I have a service class where I want to throw an exception and catch it in my controller using a try-catch block. Can someone guide how to achieve this?
You can also throw custom exceptions using the throw keyword. For instance:
throw new \Exception('Something went wrong');
Or You can also try throw_if If you need to check condition.
throw_if(
<condition>,
new \Exception('Something went wrong')
);
Here’s how you can do it in your service class:
<?php
namespace App\Services;
class MyService
{
public function someMethod()
{
// Check if some condition is not met
throw_if(
<condition>,
new \Exception('Something went wrong')
);
// If condition is met, continue with your code
}
}
Then, in your controller, you can catch this exception using a try-catch block:
<?php
namespace App\Http\Controllers;
use App\Services\MyService;
use Illuminate\Http\Request;
class MyController extends Controller
{
public function myMethod(Request $request, MyService $myService)
{
try {
// Call the method from your service class
$myService->someMethod();
// If no exception is thrown, continue with your code
} catch (Exception $e) {
// Handle the exception
// You can log the error, return a custom response, or perform any other actions
return response()->json(['error' => $e->getMessage()], 500);
}
}
}
You can use different Exception listed below.
use Illuminate\Validation\ValidationException;
use Illuminate\Auth\AuthenticationException;
use Illuminate\Auth\Access\AuthorizationException;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
use Illuminate\Database\Eloquent\ModelNotFoundException;
Creating Our Own Exception Class
Now that you know how to use Exception, You can try using your own exception.
