如何使用PHP和aws-sdk v3将大型档案上传到Amazon Glacier？

  我觉得你误解了uploadMultipartPart . uploadMultipartPart表示您在多个部分上传1个大文件 . 然后执行completeMultipartUpload以标记您已完成上传一个文件 .

  从您的代码看起来您正在上传多个文件 .

  您可能实际上不需要使用uploadMultipartPart

  也许你可以使用常规的“uploadArchive”？

  我已经在PHP SDK V3（版本3）中管理了这个，我在研究中一直找到这个问题，所以我想我也会发布我的解决方案 . 使用风险自负，错误检查或处理非常少 .

  <?php
  require 'vendor/autoload.php';
  
  use Aws\Glacier\GlacierClient;
  use Aws\Glacier\TreeHash;
  
  
  // Create the glacier client to connect with
  $glacier = new GlacierClient(array(
        'profile' => 'default',
        'region' => 'us-east-1',
        'version' => '2012-06-01'
        ));
  
  $fileName = '17mb_test_file';         // this is the file to upload
  $chunkSize = 1024 * 1024 * pow(2,2);  // 1 MB times a power of 2
  $fileSize = filesize($fileName);      // we will need the file size (in bytes)
  
  // initiate the multipart upload
  // it is dangerous to send the filename without escaping it first
  $result = $glacier->initiateMultipartUpload(array(
        'archiveDescription' => 'A multipart-upload for file: '.$fileName,
        'partSize' => $chunkSize,
        'vaultName' => 'MyVault'
        ));
  
  // we need the upload ID when uploading the parts
  $uploadId = $result['uploadId'];
  
  // we need to generate the SHA256 tree hash
  // open the file so we can get a hash from its contents
  $fp = fopen($fileName, 'r');
  // This class can generate the hash
  $th = new TreeHash();
  // feed in all of the data
  $th->update(fread($fp, $fileSize));
  // generate the hash (this comes out as binary data)...
  $hash = $th->complete();
  // but the API needs hex (thanks). PHP to the rescue!
  $hash = bin2hex($hash);
  
  // reset the file position indicator
  fseek($fp, 0);
  
  // the part counter
  $partNumber = 0;
  
  print("Uploading: '".$fileName
      ."' (".$fileSize." bytes) in "
      .(ceil($fileSize/$chunkSize))." parts...\n");
  while ($partNumber * $chunkSize < ($fileSize + 1))
  {
    // while we haven't written everything out yet
    // figure out the offset for the first and last byte of this chunk
    $firstByte = $partNumber * $chunkSize;
    // the last byte for this piece is either the last byte in this chunk, or
    // the end of the file, whichever is less
    // (watch for those Obi-Wan errors)
    $lastByte = min((($partNumber + 1) * $chunkSize) - 1, $fileSize - 1);
  
    // upload the next piece
    $result = $glacier->uploadMultipartPart(array(
          'body' => fread($fp, $chunkSize),  // read the next chunk
          'uploadId' => $uploadId,          // the multipart upload this is for
          'vaultName' => 'MyVault',
          'range' => 'bytes '.$firstByte.'-'.$lastByte.'/*' // weird string
          ));
  
    // this is where one would check the results for error.
    // This is left as an exercise for the reader ;)
  
    // onto the next piece
    $partNumber++;
    print("\tpart ".$partNumber." uploaded...\n");
  }
  print("...done\n");
  
  // and now we can close off this upload
  $result = $glacier->completeMultipartUpload(array(
    'archiveSize' => $fileSize,         // the total file size
    'uploadId' => $uploadId,            // the upload id
    'vaultName' => 'MyVault',
    'checksum' => $hash                 // here is where we need the tree hash
  ));
  
  // this is where one would check the results for error.
  // This is left as an exercise for the reader ;)
  
  
  // get the archive id.
  // You will need this to refer to this upload in the future.
  $archiveId = $result->get('archiveId');
  
  print("The archive Id is: ".$archiveId."\n");
  
  
  ?>
