Question

我正在尝试通过硬编码凭据进行身份验证时创建一个Cloudfront发行版。

但是我在运行代码时收到此错误 致命错误：未捕获的Aws \ Exception \ CredentialsException：无法从/.aws/credentials

读取凭据

似乎aws sdk正在尝试使用此处列出的第二种方法（https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/guide_credentials.html）进行身份验证-将凭据放入./aws文件夹时的一种方法

这是我的代码（摘自aws文档）-知道为什么它不起作用吗？

public function create_cloudfront_client(){

    $region='us-east-1';   
    $client = new Aws\CloudFront\CloudFrontClient([
        'profile' => 'default',
        'version'       =>  'latest',
        'region'  => 'us-east-1',

解决方案是像这样创建cloudfront客户端

 $client =  Aws\CloudFront\CloudFrontClient::factory(array(
        'region' => $bucket_region,
        'version' => 'latest',

        'credentials' => [
            'key'    => $this->aws_key,
            'secret' => $this->aws_secret,
            ]

    ));

但是我不明白为什么这个版本能工作，而下面的那个版本（来自aws docs）却不能。有人可以解释吗？谢谢

$client = new Aws\CloudFront\CloudFrontClient([
    'version'       =>  'latest',
    'region' => $bucket_region,
     'debug' => true,
    'credentials' =>[
                'key'    => $this->aws_key,
                'secret' => $this->aws_secret,
                ],
          ]);
