laravel5.6 框架邮件队列database驱动简单demo示例

1. Introduction

Laravel is a popular PHP framework that provides a simple and elegant way to implement web applications. One of its powerful features is the ability to handle email communication effectively. In this article, we will explore how to use the Laravel 5.6 framework to send emails using the database queue driver.

2. Prerequisites

Before we begin, make sure you have the following requirements:

Laravel 5.6 installed

A database connection configured in Laravel

3. Configuring the Database Queue Driver

The first step is to configure Laravel to use the database queue driver. Open the config/queue.php file and set the default connection to database:

'default' => env('QUEUE_DRIVER', 'database'),

4. Creating the Migration

Next, we need to create a migration to store the email jobs in the database. Run the following command:

php artisan queue:table
php artisan migrate

This will create a new table called jobs in your database, which will be used to store the email jobs.

5. Configuring the Mail Driver

Now, let's configure Laravel to use the database queue driver for mailing. Open the .env file and update the MAIL_DRIVER value to database:

MAIL_DRIVER=database

6. Sending Emails

We are now ready to send emails using the database queue driver. In your Laravel application, create a new Mailable class using the following command:

php artisan make:mail WelcomeEmail

This will create a new file WelcomeEmail.php in the app/Mail directory. Open this file and update the build method to define the email content:

/**
 * Build the email message.
 *
 * @return $this
 */
public function build()
{
    return $this->view('emails.welcome');
}

Here, we are using the view method to specify the email template. Make sure you create the emails/welcome.blade.php file with the content you want to send in the email.

6.1 Queuing the Email Job

Now that we have defined the email content, let's queue the email job. In your Laravel application, you can use the Mail facade to send the email and queue it in the database. Here's an example:

use App\Mail\WelcomeEmail;
use Illuminate\Support\Facades\Mail;
Mail::to('example@example.com')->queue(new WelcomeEmail());

Replace example@example.com with the recipient's email address. The queue method is used to enqueue the email job in the database.

6.2 Processing the Email Queue

Finally, we need to process the email queue to send the emails. Run the following command:

php artisan queue:work

This will start the Laravel queue worker, which checks the database for new email jobs and sends them.

7. Conclusion

In this article, we have learned how to send emails using the database queue driver in Laravel 5.6. We configured Laravel to use the database queue driver, created a migration for the email jobs, and sent emails using the queue. By using the database queue driver, we can ensure that the email jobs are processed reliably even in high-traffic scenarios. Laravel's queue system allows us to handle email communication efficiently and enhances the performance of our web applications.
