我正在尝试使用AWS SDK for PHP设置电子邮件，到目前为止还没有成功。我做了以下事情：
3.安装的pHP版本7.0.25
4.安装AWS SDK for PHP版本3。
文档指示我需要将此文件保存到以下位置：“〜/ .aws / credentials”（我正在使用MAC）
我的问题是我没有“.aws”文件夹，所以我在我的主目录中创建了一个（隐藏的aws目录），然后在那里保存了我的“凭证”文件（包含访问密钥凭据）。我收到以下错误：
PHP Fatal error: Uncaught Aws\Exception\CredentialsException: Error

在终端中执行的PHP脚本（如aws：http://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-using-sdk-php.html所述）：

首先，您不要手动创建〜/ .aws / credentials。让AWS CLI为您执行此操作。
安装CLI：pip install awscli --upgrade
删除您创建的凭据文件。
配置CLI和凭据：aws configure
您的凭据现已正确设置。
您收到的错误消息是由PHP SDK尝试从EC2实例元数据获取凭据引起的。由于您尚未为此系统配置IAM角色，因此失败。这也意味着凭证未正确存储在您的配置文件中（〜/ .aws / credentials）。
注意：更好的方法是不在EC2实例上存储凭据。而是创建IAM角色并将该角色分配给EC2实例。所有AWS软件开发人员都知道如何从实例元数据中提取凭据。
