在亚马逊AWS中获得许可被拒绝 [英] getting permission denied in amazon aws

问题描述

我正在尝试通过使用AWS凭证文件连接到Amazon s3，因为我已经完成了以下操作

I am trying to connect to amazon s3 by Using the AWS credentials file for that i have done following things

1. 我已经在.aws\credentials处创建了credentials.ini文件.它具有有效的AWSAccessKeyId和AWSSecretKey

1. I have created credentials.ini file at .aws\credentials. It have valid AWSAccessKeyId and AWSSecretKey

[default]
AWSAccessKeyId=somekey
AWSSecretKey=somesecretkey

我正在执行以下操作以使用键并列出所有对象

I am doing following to use key and list all object

.

$s3 = new Aws\S3\S3Client([
    'version' => 'latest',
    'region'  => 'us-west-2'
]);


$result = $s3->listBuckets();
var_dump($result);

我遇到错误

推荐答案

根据

According to the AWS PHP documentation, the format of the credentials file is as follows:

[default]
aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID
aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY

在您的情况下，这是我认为正在发生的事情:

In your case, here is what I believe is happening:

1. 首先，PHP库尝试从环境中获取凭据，但是它们不存在，所以...
2. 接下来，它尝试从INI文件中获取它们，但是您拼错了密钥，所以...
3. 最后，它尝试从EC2元数据服务器获取它们，但看起来您没有在EC2实例上运行，因此没有元数据服务器，并且使用curl的尝试超时.

您可以在 AWS PHP库的源代码.

冒充您的最终结果是步骤#3失败了，但实际上步骤#1，#2和#3失败了.因此，我认为此修复方法就像更正INI文件中的键名一样简单.

The end result that bubbles up to you is that step #3 failed, but actually steps #1, #2, and #3 failed. So, I think the fix is as simple as correcting the key names in the INI file.
