SMS template review and sending frequency control techniques in actual docking between PHP and Alibaba Cloud SMS interface

With the rapid development of the Internet, SMS has become an important communication method. Whether it is registration verification, payment reminders or e-commerce promotion, SMS plays an indispensable role. As a well-known SMS service provider in the industry, Alibaba Cloud SMS interface is widely used in various application scenarios. In PHP language, how to connect and reasonably use the Alibaba Cloud SMS interface is a technology that every developer needs to master.

1. SMS template review

Before using the Alibaba Cloud SMS interface to send text messages, we need to apply for and pass the review of the SMS template. Alibaba Cloud's SMS template review system is relatively strict, mainly to prevent users from sending spam SMS and malicious harassment. The following is an example SMS template review code:

require_once 'aliyun-php-sdk-core/Config.php';

use DysmsapiRequestV20170525 as Dysmsapi20170525Request;

$accessKeyId = 'your_access_key_id';
$accessKeySecret = 'your_access_key_secret';
$templateCode = 'SMS_123456789'; // 短信模板CODE
$templateParam = '{"code":"123456"}'; // 模板参数

$iClientProfile = DefaultProfile::getProfile('cn-hangzhou', $accessKeyId, $accessKeySecret);
$client = new DefaultAcsClient($iClientProfile);

$request = new Dysmsapi20170525RequestAddSmsTemplateRequest();
$request->setTemplateType(0); // 0表示短信模板
$request->setContent('您的验证码为${code},有效期为5分钟,请尽快使用。'); // 短信模板内容
$request->setTemplateName('验证码模板'); // 短信模板名称
$request->setRemark('用于用户注册时的手机验证码'); // 短信模板备注
$request->setTemplateParam($templateParam);

$response = $client->getAcsResponse($request);
if ($response->Code == 'OK') {
    echo '短信模板审核成功';
} else {
    echo '短信模板审核失败';
}

In the code, we use the SDK provided by Alibaba Cloud SMS interface to submit the SMS template review request by calling the AddSmsTemplateRequest interface. Among them, $accessKeyId and $accessKeySecret are Alibaba Cloud's authentication information and need to be replaced with your own. $templateCode is the unique identifier of the SMS template, which can be created and obtained through the Alibaba Cloud SMS console. $templateParam is a template parameter that can be replaced according to the needs of the text message content.

2. Sending Frequency Control

In order to avoid sending too frequent text messages, which may cause harassment to users and abuse of the SMS platform, the Alibaba Cloud SMS interface provides the function of controlling the sending frequency. Developers need to reasonably control the frequency of text message sending based on their own business needs. The following is an example of sending frequency control code:

function checkSendFrequency($phoneNumber, $templateCode) {
    $redis = new Redis();
    $redis->connect('127.0.0.1', 6379);

    $key = "sms_send_frequency:{$phoneNumber}:{$templateCode}";
    $count = $redis->get($key);
    if (!$count) {
        $redis->set($key, 1, 60); // 设置发送次数,并设置过期时间为60秒
    } else {
        if ($count >= 5) {
            echo '发送过于频繁,请稍后再试';
            exit;
        } else {
            $redis->incr($key); // 发送次数加一
        }
    }
}

$phoneNumber = '13812345678'; // 手机号码
$templateCode = 'SMS_123456789'; // 短信模板CODE

checkSendFrequency($phoneNumber, $templateCode);

// 发送短信代码

In the code, we use Redis to implement sending frequency control. First, we connect to the Redis server and set the corresponding IP and port information. Then, we set a unique key-value pair for each mobile phone number and SMS template. The key format is sms_send_frequency:mobile number:SMS template CODE, and the value indicates the number of times the mobile phone number and SMS template have been sent. If the number of sending exceeds 5 times, we will stop sending and prompt the user to try again later. If the number of sending times does not exceed 5, we increase the number of sending times by 1.

Through the above practical code examples of SMS template review and sending frequency control, we can learn how to connect to the Alibaba Cloud SMS interface in PHP and use related functions reasonably. Proper use of SMS template review and sending frequency control can not only ensure the security and compliance of SMS sending, but also effectively avoid abuse and harassment and improve user experience. I hope this article can provide some help to developers in connecting to the Alibaba Cloud SMS interface in practical applications.
