Implementation method of blacklist filtering and grayscale publishing in actual cases of PHP and Alibaba Cloud SMS interface docking

Overview
With the popularity of SMS marketing, the success rate and user experience of SMS sending have become an important issue for enterprises. focus of attention. In the actual process of sending text messages, in order to avoid causing trouble to users or violating regulations, a blacklist filtering function needs to be implemented. At the same time, in order to reduce the adverse effects caused by errors, a grayscale release strategy should be used to go online in batches. This article will introduce how to implement blacklist filtering and grayscale publishing through a practical case of docking PHP and Alibaba Cloud SMS interface.

1. Blacklist filtering
In the SMS marketing process, it is crucial to avoid sending invalid text messages to users. Blacklist filtering reduces user troubles and dissatisfaction by filtering out mobile phone numbers in the blacklist. The following is a sample code to implement blacklist filtering:

<?php
// 配置阿里云短信接口信息
$accessKeyId = 'your_access_key_id';
$accessKeySecret = 'your_access_key_secret';
$signName = 'your_sign_name';
$templateCode = 'your_template_code';

// 待发送的手机号码
$mobile = '13800138000';

// 检查手机号码是否在黑名单中
function inBlacklist($mobile) {
    // 从数据库中查询黑名单列表
    $blacklist = array('13800138001', '13800138002', '13800138003');

    return in_array($mobile, $blacklist);
}

try {
    // 实例化阿里云SDK的短信发送类
    $client = new DefaultAcsClient(new DefaultProfile($accessKeyId, $accessKeySecret), 'cn-hangzhou');

    // 创建短信发送请求
    $request = new CommonRequest();
    $request->setMethod(Method::POST);
    $request->setDomain('dysmsapi.aliyuncs.com');
    $request->setVersion('2017-05-25');
    $request->setAction('SendSms');
    $request->putQueryParameter('PhoneNumbers', $mobile);
    $request->putQueryParameter('SignName', $signName);
    $request->putQueryParameter('TemplateCode', $templateCode);

    // 检查手机号码是否在黑名单中
    if (!inBlacklist($mobile)) {
        // 发送短信
        $response = $client->getCommonResponse($request);
        echo $response->getBody();
    } else {
        echo '该手机号码在黑名单中，无法发送短信。';
    }
} catch (Exception $e) {
    echo '短信发送失败：' . $e->getMessage();
}

In the above sample code, you first need to configure the relevant information of the Alibaba Cloud SMS interface, including AccessKeyId, AccessKeySecret, SignName, and TemplateCode. Then call the inBlacklist function to determine whether the mobile phone number to be sent is in the blacklist. If it is not in the blacklist, call the SMS sending interface of the Alibaba Cloud SDK to send the SMS. Otherwise, a prompt message is output.

2. Grayscale release
Grayscale release refers to the continuous release of a certain function or service to a subset of users for testing to reduce the adverse effects caused by errors. In the SMS sending business, grayscale publishing can help us gradually launch new SMS templates to verify their usability and effectiveness. The following is a sample code to implement grayscale publishing:

<?php
// 配置阿里云短信接口信息
$accessKeyId = 'your_access_key_id';
$accessKeySecret = 'your_access_key_secret';
$signName = 'your_sign_name';
$templateCode = 'your_template_code';

// 获取待发送的手机号列表
function getMobileList() {
    // 从数据库中查询待发送的手机号列表
    $mobileList = array('13800138000', '13800138001', '13800138002', '13800138003');

    return $mobileList;
}

try {
    // 实例化阿里云SDK的短信发送类
    $client = new DefaultAcsClient(new DefaultProfile($accessKeyId, $accessKeySecret), 'cn-hangzhou');

    // 获取待发送的手机号列表
    $mobileList = getMobileList();

    // 按照灰度发布的比例进行循环发送短信
    $total = count($mobileList);
    $percent = 0.1; // 灰度发布的比例为10%
    $count = ceil($total * $percent); // 实际发送的手机号数量为总数的百分之十
    for ($i = 0; $i < $count; $i++) {
        $mobile = $mobileList[$i];

        // 创建短信发送请求
        $request = new CommonRequest();
        $request->setMethod(Method::POST);
        $request->setDomain('dysmsapi.aliyuncs.com');
        $request->setVersion('2017-05-25');
        $request->setAction('SendSms');
        $request->putQueryParameter('PhoneNumbers', $mobile);
        $request->putQueryParameter('SignName', $signName);
        $request->putQueryParameter('TemplateCode', $templateCode);

        // 发送短信
        $response = $client->getCommonResponse($request);
        echo $response->getBody();
    }

    echo '灰度发布成功，共发送' . $count . '条短信。';
} catch (Exception $e) {
    echo '短信发送失败：' . $e->getMessage();
}

In the above sample code, the getMobileList function is used to obtain the list of mobile phone numbers to be sent, which can be obtained from the database or other channels according to specific needs. Then, based on the proportion of grayscale publishing, calculate the actual number of mobile phone numbers that need to be sent. Grayscale publishing is achieved by sending text messages in a loop. In actual application scenarios, the proportion of grayscale publishing and the specific mobile phone number list can be adjusted as needed.

Conclusion
Through a practical case, this article introduces the implementation method of blacklist filtering and grayscale publishing in the process of docking PHP and Alibaba Cloud SMS interface, and provides relevant code examples. By implementing blacklist filtering and grayscale publishing, the success rate and user experience of text message sending can be effectively improved, and the adverse effects caused by errors can be reduced. I hope this article will be helpful to everyone in the actual development process.
