无法使用AWS php sdk连接到AWS s3。无效请求

我的错误消息：

Uncaught Aws\S3\Exception\InvalidRequestException: 
AWS Error Code: InvalidRequest, 
Status Code: 400, AWS Request ID: xxx, 
AWS Error Type: client, 
AWS Error Message: The authorization mechanism you have provided is not supported.

我的代码：

<?php

use Aws\S3\S3Client;

require 'vendor/autoload.php';

$config = array(
        'key' => 'xxx',
        'secret' => 'xxx',
        'bucket' => 'myBucket'
);

$filepath = '/var/www/html/aws3/test.txt';

//s3
// Instantiate the client.
$s3 = S3Client::factory();

// Upload a file.
$result = $s3->putObject(array(
'Bucket'       => $config['bucket'],
'Key'          => $config['key'],

)
);

echo $result['ObjectURL'];

试试这个，它肯定会起作用，代码中的问题是您没有向

工厂

函数提供凭据

<?php

ini_set('display_errors', 1);

use Aws\S3\S3Client;

require 'vendor/autoload.php';


//here we are creating client object
$s3Client = S3Client::factory(array(
            'credentials' => array(
                'key' => 'YOUR_AWS_ACCESS_KEY_ID',
                'secret' => 'YOUR_AWS_SECRET_ACCESS_KEY',
            )
        ));

// Upload a file.    
$filepath = '/var/www/html/aws3/test.txt';

$result = $s3Client->putObject(array(
    'Bucket' => "myBucket",//some filebucket name
    'Key' => "some_file_name.txt",//name of the object with which it is created on s3
    'SourceFile' => $filepath,
    'Endpoint' => 's3-eu-central-1.amazonaws.com',
    'Signature' => 'v4',
    'Region' => 'eu-central-1',
        )
);

echo $result['ObjectURL'];

谢谢！但是我仍然得到
AWS错误代码：InvalidRequest，状态代码：400，AWS请求ID:xxx，AWS错误类型：client，AWS错误消息：您提供的授权机制不受支持。请使用AWS4-HMAC-SHA256。
尽管：（@vonhact）请确保您使用的是正确的
密钥
和
机密
。我现在就可以使用了！请查看我的编辑。在您的示例中，您还必须在构造函数中传递
签名
和
区域
。
