如何在 Amazon SNS 下订阅多个电话号码到一个主题？

Question

Amazon 提供了下面的 php 示例代码来订阅某个主题的号码。然而，这一次只能添加一个个数字。

如何将多个号码（$endpoint）添加到同一主题？最后需要什么代码？

PHP 示例代码：

<?php
// snippet-start:[sns.php.subscribe_text_sms.complete]
// snippet-start:[sns.php.subscribe_text_sms.import]
require 'vendor/autoload.php';

use Aws\Sns\SnsClient; 
use Aws\Exception\AwsException;
// snippet-end:[sns.php.subscribe_text_sms.import]

/**
 * Prepares to subscribe an endpoint by sending the endpoint a confirmation message.
 *
 * This code expects that you have AWS credentials set up per:
 * https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/guide_credentials.html
 */
 
// snippet-start:[sns.php.subscribe_text_sms.main]
$SnSclient = new SnsClient([
    'profile' => 'default',
    'region' => 'us-east-1',
    'version' => '2010-03-31'
]);

$protocol = 'sms';
$endpoint = '+1XXX5550100';
$topic = 'arn:aws:sns:us-east-1:111122223333:MyTopic';

try {
    $result = $SnSclient->subscribe([
        'Protocol' => $protocol,
        'Endpoint' => $endpoint,
        'ReturnSubscriptionArn' => true,
        'TopicArn' => $topic,
    ]);
    var_dump($result);
} catch (AwsException $e) {
    // output error message if fails
    error_log($e->getMessage());
} 
// snippet-end:[sns.php.subscribe_text_sms.main]
// snippet-end:[sns.php.subscribe_text_sms.complete]
// snippet-sourcedescription:[SubscribeTextSMS.php demonstrates how to send a confirmation message as a text message.]

解决方案实际上非常简单。我只需要添加一个数字列表（通过数组）并创建一个 foreach 循环：

<?php
// snippet-start:[sns.php.subscribe_text_sms.complete]
// snippet-start:[sns.php.subscribe_text_sms.import]
require 'vendor/autoload.php';

use Aws\Sns\SnsClient; 
use Aws\Exception\AwsException;
// snippet-end:[sns.php.subscribe_text_sms.import]

/**
 * Prepares to subscribe an endpoint by sending the endpoint a confirmation message.
 *
 * This code expects that you have AWS credentials set up per:
 * https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/guide_credentials.html
 */
 
// snippet-start:[sns.php.subscribe_text_sms.main]
$SnSclient = new SnsClient([
    'profile' => 'default',
    'region' => 'us-east-1',
    'version' => '2010-03-31'
]);

$protocol = 'sms';
$endpoints = array('+1XXX5550100', '+2XXX5550100', '+3XXX5550100');
$topic = 'arn:aws:sns:us-east-1:111122223333:MyTopic';

foreach ($endpoints as $endpoint) {
    try {
        $result = $SnSclient->subscribe([
            'Protocol' => $protocol,
            'Endpoint' => $endpoint,
            'ReturnSubscriptionArn' => true,
            'TopicArn' => $topic,
        ]);
        var_dump($result);
    } catch (AwsException $e) {
        // output error message if fails
        error_log($e->getMessage());
    } 
}
// snippet-end:[sns.php.subscribe_text_sms.main]
// snippet-end:[sns.php.subscribe_text_sms.complete]
