SMS sending mechanism and message channel design in the actual case of PHP and Alibaba Cloud SMS interface docking

Overview:
In today’s Internet era, text messages have become an important part of people’s lives, and The function of sending text messages has also become an indispensable part of the development of many applications. This article will use PHP language as an example to introduce how to implement the SMS sending mechanism and the design of the message channel through the Alibaba Cloud SMS interface.

1. Introduction to Alibaba Cloud SMS Interface
Alibaba Cloud SMS Interface is a set of SMS sending services provided by Alibaba Cloud. Whether it is verification code, marketing SMS or notification SMS, it can be implemented through this interface . Sending text messages through this interface not only meets actual needs, but also ensures the high reliability of text messages.

2. SMS sending mechanism design

1. Register Alibaba Cloud account and apply for SMS service
   First, we need to register an Alibaba Cloud account and apply for SMS service. When applying for SMS service, you need to provide some necessary information, such as business name, signature, etc. After passing the review, Alibaba Cloud will provide us with AccessKey ID and AccessKey Secret. These two keys are our credentials for calling the SMS interface.

2. Install Alibaba Cloud SDK
   To use Alibaba Cloud SMS interface in PHP projects, we can use Alibaba Cloud SDK for development. First, we need to install Alibaba Cloud SDK in the project. It can be installed through composer. The command is as follows:

   composer require alibabacloud/sdk

3. Write SMS sending code
   In the PHP project, we can send SMS messages by calling the API provided by Alibaba Cloud SDK. The following is a simple sample code. The specific parameters should be filled in according to actual needs:

<?php
require 'vendor/autoload.php';

use AlibabaCloudClientAlibabaCloud;
use AlibabaCloudClientExceptionClientException;
use AlibabaCloudClientExceptionServerException;

AlibabaCloud::accessKeyClient('your-access-key-id', 'your-access-key-secret')
    ->regionId('cn-hangzhou')
    ->asDefaultClient();

try {
    $result = AlibabaCloud::rpcRequest()
                          ->product('Dysmsapi')
                          ->scheme('https')
                          ->version('2017-05-25')
                          ->action('SendSms')
                          ->method('POST')
                          ->options([
                                        'query' => [
                                            'PhoneNumbers' => '13000000000',
                                            'SignName'     => '阿里云',
                                            'TemplateCode' => 'SMS_0000001',
                                            'TemplateParam' => '{"code":"123456"}'
                                        ],
                                    ])
                          ->request();
    print_r($result->toArray());
} catch (ClientException $e) {
    echo $e->getErrorMessage() . PHP_EOL;
} catch (ServerException $e) {
    echo $e->getErrorMessage() . PHP_EOL;
}
?>

In the above code, we use the rpcRequest() method provided by AlibabaCloud SDK to send text messages. Among them, we need to fill in the AccessKey ID, AccessKey Secret, Alibaba Cloud SMS signature, SMS template ID, and the mobile phone number for receiving SMS messages.

3. Message channel design
In order to better manage the status of SMS sending and record related operation logs, we can set up a message channel to process the results of SMS sending. The following is a simple message channel design example:

1. Create database table
   First, we need to create a database table to record the results and related information of SMS sending. The structure of the table is as follows:

CREATE TABLE `sms_logs` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `phone_number` varchar(20) NOT NULL COMMENT '手机号码',
  `template_code` varchar(20) NOT NULL COMMENT '短信模板ID',
  `content` text NOT NULL COMMENT '短信内容',
  `result_code` varchar(20) NOT NULL COMMENT '发送结果编码',
  `result_msg` varchar(255) NOT NULL COMMENT '发送结果消息',
  `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '发送时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

2. Writing the code for sending text messages
   In the code for sending text messages, we can save the sending results to the database. The following is an example:

// 发送短信并将结果保存到数据库中
$result = AlibabaCloud::rpcRequest()
                        ->product('Dysmsapi')
                        ->scheme('https')
                        ->version('2017-05-25')
                        ->action('SendSms')
                        ->method('POST')
                        ->options([
                                      'query' => [
                                          'PhoneNumbers' => '13000000000',
                                          'SignName'     => '阿里云',
                                          'TemplateCode' => 'SMS_0000001',
                                          'TemplateParam' => '{"code":"123456"}'
                                      ],
                                  ])
                        ->request();
                        
// 将发送结果保存到数据库中
if ($result['Code'] == 'OK') {
  // 发送成功
  $resultCode = 'success';
  $resultMsg = '短信发送成功';
} else {
  // 发送失败
  $resultCode = 'fail';
  $resultMsg = $result['Message'];
}

// 将发送结果保存到数据库
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'your_username', 'your_password');
$stmt = $pdo->prepare("INSERT INTO sms_logs (phone_number, template_code, content, result_code, result_msg) 
                      VALUES (:phone_number, :template_code, :content, :result_code, :result_msg)");
$stmt->execute([
    'phone_number'  => '13000000000',
    'template_code' => 'SMS_0000001',
    'content'       => '您的验证码是123456',
    'result_code'   => $resultCode,
    'result_msg'    => $resultMsg
]);

Through the above code, we save the sent text messages and sending results into the database to facilitate subsequent query and management.

Conclusion:
By connecting PHP to the Alibaba Cloud SMS interface, we can quickly and reliably implement the function of sending SMS messages. At the same time, by properly designing the SMS sending mechanism and message channel, we can better manage the status of SMS sending and record related operation logs, providing us with better SMS services. I hope this article can be helpful to the development of SMS sending using PHP and Alibaba Cloud SMS interface.
