Question

被告知，我正在尝试使用aw rekognition indexFaces命令将图像上传到“集合”。我成功创建了该集合，但是当我使用IndexFaces命令时，我们遇到以下错误：

Fatal error: Uncaught exception 'Aws\Rekognition\Exception\RekognitionException' with message 'Error executing "IndexFaces" on "https://rekognition.us-east-1.amazonaws.com"; AWS HTTP error: Client error: `POST https://rekognition.us-east-1.amazonaws.com` resulted in a `400 Bad Request` response: {"__type":"InvalidImageFormatException","Code":"InvalidImageFormatException","Message":"Request has invalid image format (truncated...) InvalidImageFormatException (client): Request has invalid image format - {"__type":"InvalidImageFormatException","Code":"InvalidImageFormatException","Message":"Request has invalid image format"}' GuzzleHttp\Exception\ClientException: Client error: `POST https://rekognition.us-east-1.amazonaws.com` resulted in a `400 Bad Request` response: {"__type":"InvalidImageFormatException","Code":"InvalidImageFormatException","Message":"Request has invalid image format (truncated...) in /home/admin/web/mbracecloud.com/public_html/Aws/GuzzleHttp/Exception/RequestException.php:113 Stack trace: #0 /home/admi in /home/admin/web/mbracecloud.com/public_html/Aws/Aws/WrappedHttpHandler.php on line 195

我们正在使用以下代码执行命令

$result = $s3->indexFaces([
        'CollectionId' => 'mbrace', 
        'ExternalImageId' => 'faces',
        'Image' => [ 
            'Bytes' => 'images/user.jpg',
            
        ],
        'MaxFaces' => 1,
        'QualityFilter' => 'NONE',
    ]);

我错在哪里我错了。任何想法如何解决这个问题？

Answer 1

indexFaces() API调用需要 Bytes（用于内嵌图像），或 S3Object用于指定来自Amazon S3的图像。

如果您是从本地磁盘引用文件，则Bytes将需要包含图像文件的内容，但是您的代码提供了文件名。这就是为什么它生成InvalidImageFormatException的原因。

您应该阅读文件的内容，并将其作为字节提供。
