Aws Php SDK - 使用硬编码凭据创建 Cloudfront 分发答案

【问题标题】：Aws Php SDk - Create Cloudfront distribution using hard-coded credentialsAws Php SDK - 使用硬编码凭据创建 Cloudfront 分发
【发布时间】：2019-05-09 17:37:58
【问题描述】：

我正在尝试创建一个云端分发，同时通过硬编码凭据进行身份验证。

但是当我运行我的代码时我收到了这个错误 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 - 您将凭据放入 ./aws 文件夹时的一种方法

这是我的代码（取自 aws 文档） - 知道为什么这不起作用吗？

public function create_cloudfront_client(){

    $region='us-east-1';   
    $client = new Aws\CloudFront\CloudFrontClient([
        'profile' => 'default',
        'version'       =>  'latest',
        'region'  => 'us-east-1', 
         'debug' => true,
        'credentials' =>[
                    'key'    => $this->aws_key,
                    'secret' => $this->aws_secret,
                    ],
              ]);

    $originName = 'cloudfrontme';
    $s3BucketURL = 'https://s3.amazonaws.com/cloudfrontme';
    $callerReference = 'uniquestring99';
    $comment = 'Created by AWS SDK for PHP';
    $cacheBehavior = [

            'Items' => ['HEAD', 'GET'],

    ];

    $enabled = false;
    $origin = [

            [
                'DomainName' => $s3BucketURL,

    ];



    $distribution = [

        'DefaultCacheBehavior' => $cacheBehavior,
        'Enabled' => $enabled,
        'Origins' => $origin,

    ];

    try {
        $result = $client->createDistribution([
            'DistributionConfig' => $distribution, //REQUIRED
        ]);
        var_dump($result);
    } catch (AwsException $e) {
        // output error message if fails
        echo $e->getMessage();
        echo "\n";
    }
}

【解决方案1】：

解决方案是像这样创建云端客户端

 $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可以工作，而下面的版本（来自 aws docs）却不行。谁能解释一下？谢谢

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