s3上傳音頻文件，但不播放。如何將音頻流上傳到s3？

Question

我正在嘗試將我的Amazon Polly語音文件上傳到s3。他們成功上傳，所以沒有我可以使用的錯誤，但他們不玩。

我有一個包含歌詞的對象數組，包括字符串。我循環他們，並創建一個MP3文件，然後上傳到S3。

數據結構：

Array 
(
    [0] => stdClass Object 
     (
      [lyrics] => sample lyrics 

     ) 

    [1] => stdClass Object 
     (
      [lyrics] => sample lyrics 

     ) 

    [2] => stdClass Object 
     (
      [lyrics] => sample lyrics 

     ) 

) 

。
波利和S3功能：

foreach($final as $key=>$f){ 

    $pollySpeech = $polly->synthesizeSpeech([ 
     'OutputFormat' => 'mp3', 
     'Text' => $f->lyrics, 
     'TextType' => 'text', 
     'VoiceId' => 'Salli', 
    ]); 

    print_r($pollySpeech); 

    try { 
     $s3->putObject([ 
       'Bucket' => 'testbucket' 
       'Key' => $key.'.mp3', 
       'Body' => $pollySpeech, 
       'ContentType' => 'audio/mpeg', 
      'ACL' => 'public-read', 
     ]); 
    } catch (Aws\S3\Exception\S3Exception $e) { 
     echo "There was an error uploading the file.\n"; 
    } 

}

Answer 1

$pollySpeech->get('AudioStream')->getContents(); 

所以好像我試圖將整個對象上傳到S3。上面的代碼讓我可以正確地上傳音頻流。

foreach($final as $key=>$f){ 

    $pollySpeech = $polly->synthesizeSpeech([ 
     'OutputFormat' => 'mp3', 
     'Text' => $f->lyrics, 
     'TextType' => 'text', 
     'VoiceId' => 'Salli', 
    ]); 

    print_r($pollySpeech); 

    try { 
     $s3->putObject([ 
       'Bucket' => 'testbucket' 
       'Key' => $key.'.mp3', 
       'Body' => $pollySpeech->get('AudioStream')->getContents(), 
       'ContentType' => 'audio/mpeg', 
      'ACL' => 'public-read', 
     ]); 
    } catch (Aws\S3\Exception\S3Exception $e) { 
     echo "There was an error uploading the file.\n"; 
    } 

}
