What are the advantages of combining PHP queue and SMS service?

In actual application development, we often encounter the need to send text messages. Whether it is registration verification code, password reset, order notification, logistics information, etc., SMS service is a must. Function. For text message sending in high-concurrency scenarios, we need to consider performance and reliability issues.

The introduction of PHP queues can effectively solve performance problems in high concurrency situations. The queue is a first-in, first-out data structure. You can put SMS sending tasks into the queue, and then use the background task processing process to process the tasks one by one. In this way, the process of sending text messages will not block the execution of the main program, improving the program's response speed and concurrent processing capabilities.

In addition, using queues can also improve the reliability of text message sending. When sending text messages, we can put the task into the queue. Even if an exception occurs during the text message sending process, we can use the queue to ensure that the task will not be lost. When the sending task fails, the task can be put back into the queue and the text message can be resent through the background task processing process to ensure the reliability of text message sending.

Below we use a specific example to demonstrate how to combine PHP queue and SMS service.

Suppose we use the Laravel framework to develop our application. First, we need to install a queue manager such as Redis or Beanstalkd. I will use Redis as an example to illustrate.

First, we need to install Predis, a PHP library used to connect to Redis, in the Laravel project. You can use Composer to install:

composer require predis/predis

Next, we need to configure the Redis connection information in the Laravel configuration file, which can be configured in the config/database.php file:

'redis' => [
    'client' => 'predis',
    'default' => [
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD', null),
        'port' => env('REDIS_PORT', 6379),
        'database' => 0,
    ],
]

After that, we need to add Redis connection-related configuration in the .env file:

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

After completing the above steps, we can use Redis as queue management in the Laravel project device.

Next, we need to install the SDK of an SMS service provider, such as Alibaba Cloud SMS Service, Tencent Cloud SMS Service, etc., and configure and use it according to the corresponding documents.

In Laravel, we can configure the SMS service provider's relevant information in the .env file, and then use the SMS service SDK through Laravel's service container and dependency injection.

For example, if we use the SDK of Alibaba Cloud SMS Service, we can add the following configuration to the .env file:

ALIYUN_ACCESS_KEY_ID=your_access_key_id
ALIYUN_ACCESS_KEY_SECRET=your_access_key_secret
ALIYUN_SMS_SIGN_NAME=your_sms_sign_name
ALIYUN_SMS_TEMPLATE_CODE=your_sms_template_code

Then, define a method for sending SMS messages in Laravel Task class implements specific logic for sending text messages. We can define a SendSms class, which contains the handle method for sending text messages. The sample code is as follows:

<?php

namespace AppJobs;

use IlluminateContractsQueueShouldQueue;
use IlluminateQueueInteractsWithQueue;
use IlluminateQueueQueue;
use IlluminateSupportFacadesLog;
use AlibabaCloudClientAlibabaCloud;
use AlibabaCloudClientExceptionClientException;
use AlibabaCloudClientExceptionServerException;

class SendSms implements ShouldQueue
{
    use InteractsWithQueue;

    public function handle()
    {
        try {
            AlibabaCloud::accessKeyClient(config('aliyun.access_key_id'), config('aliyun.access_key_secret'))
                ->regionId('cn-hangzhou')
                ->asGlobalClient();

            AlibabaCloud::rpc()
                ->product('Dysmsapi')
                ->version('2017-05-25')
                ->action('SendSms')
                ->method('POST')
                ->options([
                    'query' => [
                        'RegionId' => 'cn-hangzhou',
                        'PhoneNumbers' => 'your_phone_number',
                        'SignName' => config('aliyun.sms_sign_name'),
                        'TemplateCode' => config('aliyun.sms_template_code'),
                        'TemplateParam' => json_encode([
                            'name' => 'your_name',
                            'code' => 'your_verification_code',
                        ]),
                    ],
                ])
                ->request();
            
            Log::info('Send SMS success.');
        } catch (ClientException $e) {
            Log::error('Send SMS failed.', ['exception' => $e]);
        } catch (ServerException $e) {
            Log::error('Send SMS failed.', ['exception' => $e]);
        }
    }
}

Finally, we can put the task of sending text messages into the queue where we need to send text messages. The sample code is as follows:

use AppJobsSendSms;

SendSms::dispatch();

Through the above code example, we It can be seen that the combination of PHP queue and SMS service can easily realize the requirement of high concurrent sending of SMS and improve the performance and reliability of SMS sending. Of course, the specific implementation methods and details need to be determined based on actual needs and the SDK of the SMS service provider. Hope this article helps you!
