Amazon S3-如何修复“我们计算的请求签名与签名不匹配”错误？

Question

我正在尝试用以下代码连接到我的Amazon S3 bucket：

// Create a `Aws` object using a configuration file
$aws = Aws::factory('config.php');

// Get the client from the service locator by namespace
$s3Client = $aws->get('s3');

$bucket = "xxx";
$keyname = "xxx";

try {
    $result = $s3Client->putObject(array(
        'Bucket' => $bucket,
        'Key' => $keyname,
        'Body' => 'Hello World!'
    ));

    $file_error = false;
} catch (Exception $e) {
    $file_error = true;

    echo $e->getMessage();

    die();
}

我的config.php文件如下：

return [
    // Bootstrap the configuration file with AWS specific features
    'includes' => ['_aws'],
    'services' => [
        // All AWS clients extend from 'default_settings'. Here we are
        // overriding 'default_settings' with our default credentials and
        // providing a default region setting.
        'default_settings' => [
            'params' => [
                'credentials' => [
                    'key'    => 'key',
                    'secret' => 'secret'
                ]
            ]
        ]
    ]
];

它将产生以下错误：

经过两天的调试，终于发现了问题……

我分配给对象的键以句点开始，即..\images\abc.jpg，这导致了错误的发生。

我希望API提供更多有意义和相关的错误信息，唉，我希望这能帮助其他人！
