将 UploadMultipartPart 与 AWS SDK 或 CLI 配合使用

以下命令上传存档的前 1 MiB（1024 x 1024 字节）部分：

aws glacier upload-multipart-part --body part1 --range 'bytes 0-1048575/*' --account-id - --vault-name my-vault --upload-id 19gaRezEXAMPLES6Ry5YYdqthHOC_kGRCT03L9yetr220UmPtBYKk-OssZtLqyFu7sY1_lR7vgFuJV6NtcV5zpsJ

Amazon Glacier 在执行操作时需要一个账户 ID 参数，但您可以使用连字符来指定正在使用的账户。

正文参数采用本地文件系统上分段文件的路径。范围参数采用 HTTP 内容范围，指示该分段在已完成的存档中占用的字节。上传 ID 由 aws glacier initiate-multipart-upload 命令返回，也可以使用 aws glacier list-multipart-uploads 获取它。

有关使用 AWS CLI 分段上传到 Amazon Glacier 的更多信息，请参阅《AWS CLI 用户指南》中的“使用 Amazon Glacier”。

创建 Buffer 对象的 1 兆字节区块的分段上传。

// Create a new service object and some supporting variables
var glacier = new AWS.Glacier({ apiVersion: "2012-06-01" }),
  vaultName = "YOUR_VAULT_NAME",
  buffer = new Buffer(2.5 * 1024 * 1024), // 2.5MB buffer
  partSize = 1024 * 1024, // 1MB chunks,
  numPartsLeft = Math.ceil(buffer.length / partSize),
  startTime = new Date(),
  params = { vaultName: vaultName, partSize: partSize.toString() };

// Compute the complete SHA-256 tree hash so we can pass it
// to completeMultipartUpload request at the end
var treeHash = glacier.computeChecksums(buffer).treeHash;

// Initiate the multipart upload
console.log("Initiating upload to", vaultName);
// Call Glacier to initiate the upload.
glacier.initiateMultipartUpload(params, function (mpErr, multipart) {
  if (mpErr) {
    console.log("Error!", mpErr.stack);
    return;
  }
  console.log("Got upload ID", multipart.uploadId);

  // Grab each partSize chunk and upload it as a part
  for (var i = 0; i < buffer.length; i += partSize) {
    var end = Math.min(i + partSize, buffer.length),
      partParams = {
        vaultName: vaultName,
        uploadId: multipart.uploadId,
        range: "bytes " + i + "-" + (end - 1) + "/*",
        body: buffer.slice(i, end),
      };

    // Send a single part
    console.log("Uploading part", i, "=", partParams.range);
    glacier.uploadMultipartPart(partParams, function (multiErr, mData) {
      if (multiErr) return;
      console.log("Completed part", this.request.params.range);
      if (--numPartsLeft > 0) return; // complete only when all parts uploaded

      var doneParams = {
        vaultName: vaultName,
        uploadId: multipart.uploadId,
        archiveSize: buffer.length.toString(),
        checksum: treeHash, // the computed tree hash
      };

      console.log("Completing upload...");
      glacier.completeMultipartUpload(doneParams, function (err, data) {
        if (err) {
          console.log("An error occurred while uploading the archive");
          console.log(err);
        } else {
          var delta = (new Date() - startTime) / 1000;
          console.log("Completed upload in", delta, "seconds");
          console.log("Archive ID:", data.archiveId);
          console.log("Checksum:  ", data.checksum);
        }
      });
    });
  }
});
