How to use middleware for SMS sending in Laravel

How to use middleware to send text messages in Laravel

Sending Chinese text messages has become a very common need in modern society, especially in various countries. in an application. As a popular PHP framework, the Laravel framework provides powerful functions and concise syntax to help us build efficient web applications. In Laravel, we can use middleware to implement the SMS sending function, which provides us with a very convenient and flexible way to handle the logic of SMS sending. This article will introduce how to use middleware to send text messages in Laravel and provide specific code examples.

1. Install dependency package

First, we need to install a dependency package for sending text messages. In Laravel, we usually use the Laravel Notification component to implement notification functions. We can use the following command to install the Laravel Notification component:

composer require laravel-notification/channels

2. Create SMS notification class

Next, we need to create an SMS notification class, which will be responsible for the specific SMS sending logic. We can use the following command to generate a text message notification class:

php artisan make:notification SmsNotification

The generated text message notification class will be located in the app/Notifications directory, and we can define the content of the text message sent in this class , delivery channels, etc. For example, we can write specific SMS sending logic in the toSms method of the SmsNotification class:

public function toSms($notifiable)
{
    return (new SmsMessage)
        ->content('This is a test SMS message');
}

3. Create SMS sending middleware

Next, we need to create a middleware to trigger the sending of text messages. We can use the following command to generate a middleware:

php artisan make:middleware SmsMiddleware

The generated middleware will be located in the app/Http/Middleware directory, and we can call the SMS notification class in the middleware to send text messages. For example, we can trigger SMS sending in the handle method of the SmsMiddleware class:

public function handle($request, Closure $next)
{
    $user = $request->user();
    $user->notify(new SmsNotification);
    
    return $next($request);
}

4. Register Middleware

Finally , we need to register the middleware into the application to trigger SMS sending on a specific request. We can edit the app/Http/Kernel.php file and add the middleware to the $routeMiddleware array. For example, we can register the middleware as 'sms':

protected $routeMiddleware = [
    // other middlewares
    'sms' => AppHttpMiddlewareSmsMiddleware::class,
];

5. Using the middleware

Now, we can Use middleware to trigger SMS sending. For example, we can use middleware in routing:

Route::post('/example', function () {
    // do something
    
})->middleware('sms');

When a request passes through this routing code, the middleware will be triggered, thereby enabling SMS sending.

The above are the steps and code examples for using middleware to send text messages in Laravel. By leveraging Laravel's middleware capabilities, we can easily decouple the SMS sending logic from our application, improving the readability and maintainability of the code. I hope this article will help you use middleware to send text messages in Laravel!
