我正在尝试通过使用AWS凭证文件连接到amazon s3，为此我做了以下事情
-
我已经在
.aws'credentials创建了credentials.ini文件。有有效的AWSAccessKeyId和AWSSecretKey[default] AWSAccessKeyId=somekey AWSSecretKey=somesecretkey -
我正在做以下使用键并列出所有对象
.
$s3 = new Aws'S3'S3Client([
'version' => 'latest',
'region' => 'us-west-2'
]);
$result = $s3->listBuckets();
var_dump($result);
，我得到错误

根据AWS PHP文档，凭证文件的格式如下:
[default]
aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID
aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY
对于你的情况，我认为是这样的:
- 首先，PHP库尝试从环境中获取凭据，但它们不存在，所以…
- 接下来，它尝试从INI文件中获取它们，但是你拼错了键，所以…
- 最后，它尝试从EC2元数据服务器获取它们，但看起来你不是在EC2实例上运行，所以没有元数据服务器，并且尝试使用curl超时。
您可以在AWS PHP库的源代码中清楚地看到所有这些。
最终的结果是步骤3失败了，但实际上步骤1、2和3都失败了。所以，我认为修复就像纠正INI文件中的关键名称一样简单。
