PHP上传录音文件流到awss3非常慢。

1. 使用Amazon S3 SDK中的multipart upload功能，以提高上传速度。

2. 优化网络连接，建议将上传地址设为与AWS S3在同一区域的endpoint。

3. 压缩录音文件，并在上传前使用流式传输，以减少传输的时间与数据量。

4. 使用AWS Elastic Transcoder对录音文件进行转码，并上传转码后的文件，使文件大小更小，从而提高上传速度。

示例代码：

使用Amazon S3 SDK中的multipart upload功能：

// Include the AWS SDK using the Composer autoloader. require 'vendor/autoload.php';

use Aws\Common\Exception\MultipartUploadException; use Aws\S3\MultipartUploader; use Aws\S3\S3Client;

// Instantiate a client object $s3 = S3Client::factory();

// Specify the file path and key name in S3 $key = 'my-file.txt'; $pathToFile = '/path/to/my-file.txt';

// Use multipart upload to improve upload speed $uploader = new MultipartUploader($s3, $pathToFile, [ 'bucket' => 'my-bucket', 'key' => $key, ]);

try { $result = $uploader->upload(); echo "Upload complete: {$result['ObjectURL']}\n"; } catch (MultipartUploadException $e) { echo $e->getMessage() . "\n"; }

使用AWS Elastic Transcoder对录音文件进行转码：

// Include the AWS SDK using the Composer autoloader. require 'vendor/autoload.php';

use Aws\ElasticTranscoder\ElasticTranscoderClient;

// Instantiate a client object $transcoder = ElasticTranscoderClient::factory();

// Specify the input and output files in S3 $inputKey = 'my-input-file.mp3'; $outputKey = 'my-output-file.mp3';

// Set up the transcoding job $result = $transcoder->createJob([ 'PipelineId' => 'my-pipeline-arn', 'Input' => [ 'Key' => $inputKey, 'FrameRate' => 'auto', 'Resolution' => 'auto', 'AspectRatio' => 'auto', 'Interlaced' => 'auto', 'Container' => 'auto', ], 'Output' => [ 'Key' => $outputKey, 'PresetId' => '1351620000001-300040', // MP3 64Kbps ], ]);

// Wait for the job to complete $jobId = $result['Job']['Id']; $transcoder->waitUntil('jobComplete', [ 'Id' => $job
