我正在使用 AWS 示例来调用适用于 PHP 的 AWS 开发工具包。将代码转换为函数时，出现以下错误：未捕获错误：调用成员函数 sendEmail()第 41 行似乎是问题所在： $result = $SesClient->sendEmail([我尝试删除结果变量并注释掉它的用法当我运行代码并且它不是一个正常工作的函数时，我不确定我在这里做错了什么，我确信这可能是一个简单的错误。我在这里先向您的帮助表示感谢<?php// If necessary, modify the path in the require statement below to refer to the // location of your Composer autoload.php file.require '/vendor/autoload.php';use Aws\Ses\SesClient;use Aws\Exception\AwsException;// Create an SesClient.

Answer 1

尝试在 send_email 函数中声明 $SesClient

Answer 2

它在没有函数的情况下工作，因为您在函数之外声明了 $SesClient 。在函数之后声明它 - 或通过它传递给函数

function function send_email($recipient, $message, $subject, $SesClient) {

/* snip */

}

echo send_email('[e-mail]', 'test', 'test subject', $SesClient);
