【问题描述】：

我的电子邮件最近出现问题，一周前我开始在发送电子邮件时遇到错误，问题是有时当我调用此函数sendEmail 时，它永远不会返回Aws/Result 或任何Exception。所以我的脚本循环等待它。这个问题是零星的。我想我的请求无法添加到 AWS 队列中，但至少我会得到一个异常。

我试图找到一个可以设置为不永远等待的超时设置，但我在文档中找不到它。我有 2 年使用此服务，直到现在我还没有收到错误。

其他人遇到过这个问题吗？

我可以在哪里设置与 SES 类相关的调用的超时时间？

简单代码：

use Aws\Ses\SesClient;
use Aws\Ses\Exception\SesException;

// Replace sender@example.com with your "From" address.
// This address must be verified with Amazon SES.
define('SENDER', 'sender@example');

// Replace recipient@example.com with a "To" address. If your account
// is still in the sandbox, this address must be verified.
define('RECIPIENT', 'recipient@example.com');

define('SUBJECT', 'Amazon SES test (AWS SDK for PHP)');

define('HTMLBODY', '<h1>AWS Amazon Simple Email Service Test Email</h1>' .
    '<p>This email was sent with <a href="https://aws.amazon.com/ses/">' .
    'Amazon SES</a> using the <a href="https://aws.amazon.com/sdk-for-php/">' .
    'AWS SDK for PHP</a>.</p>');
define('TEXTBODY', 'This email was send with Amazon SES using the AWS SDK for PHP.');

define('CHARSET', 'UTF-8');

$_AWSAPICredentials = array(
    'key' => 'AWSAPIKEY',
    'secret' => 'AWSAPISECRET',
);
$_AWSAPIVersion = 'latest';
$_AWSAPIRegion = 'us-west-2';

$_SES = new SesClient([
    'version' => $_AWSAPIVersion,
    'region' => $_AWSAPIRegion,
    'credentials' => $_AWSAPICredentials,
]);

$params = [
    'Destination' => [
        'ToAddresses' => [
            RECIPIENT,
        ],
    ],
    'Message' => [
        'Body' => [
            'Html' => [
                'Charset' => CHARSET,
                'Data' => HTMLBODY,
            ],
            'Text' => [
                'Charset' => CHARSET,
                'Data' => TEXTBODY,
            ],
        ],
        'Subject' => [
            'Charset' => CHARSET,
            'Data' => SUBJECT,
        ],
    ],
    'Source' => SENDER
];

try {
    $result = $_SES->sendEmail($params);
    $sMessageId = $result->get('MessageId');
} catch (SesException  $e) {
    print_r($e->getAwsErrorMessage());
}

注意：我使用的是 AWS SDK PHP 版本 3.67.20

当它失败时，我得到这个错误

AWS HTTP error: Client error: `POST https://email.us-west-2.amazonaws.com` resulted in a `403 Forbidden` response:

【解决方案1】：

好吧，我找到了解决方案....我已经在我的服务器中同步了 NTP 时间，现在它可以工作了。我让我关注的 Ubuntu SO 的链接 https://www.tecklyfe.com/fix-ubuntu-timedatectl-ntp-sync-no/

也许我机器的时钟至少足够同步，所以不应该每次都出现这个错误。
