AWS-SDK：执行 GetObject() 得到一个空流

Question

我的主要目标是获取特定对象的信息。

$client = $adapter->getClient();
$objectInfo = $client->getObject(
    [
        'Bucket' => 'bucket-name',
        'Key'    => "key-name",
    ]
);

dd($objectInfo->toArray()["Body"]);

运行时，我得到了结果：

GuzzleHttp\Psr7\Stream {
  -stream: stream resource {
    wrapper_type: "PHP"
    stream_type: "TEMP"
    mode: "w+b"
    unread_bytes: 0
    seekable: true
    uri: "php://temp"
    options: []
  }
  -size: null
  -seekable: true
  -readable: true
  -writable: true
  -uri: "php://temp"
  -customMetadata: []
}

任何解决它的想法将不胜感激。

我认为您应该尝试从对象调用 getContents() 方法。有关更多输入，请参阅以下页面 https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/s3-stream-wrapper.html

https://docs.aws.amazon.com/aws-sdk-php/v3/api/class-GuzzleHttp.Psr7.Stream.html#_getContents

$objectInfo['Body']->getContents();
