Use CompleteMultipartUpload with an AWS SDK or command line tool

The following code examples show how to use CompleteMultipartUpload.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code examples:

CLI
AWS CLI

The following command completes a multipart upload for the key multipart/01 in the bucket my-bucket:

aws s3api complete-multipart-upload --multipart-upload file://mpustruct --bucket my-bucket --key 'multipart/01' --upload-id dfRtDYU0WWCCcH43C3WFbkRONycyCpTJJvxu2i5GYkZljF.Yxwh6XG7WfS2vC4to6HiV6Yjlx.cph0gtNBtJ8P3URCSbB7rjxI5iEwVDmgaXZOGgkk5nVTW16HOQ5l0R

The upload ID required by this command is output by create-multipart-upload and can also be retrieved with list-multipart-uploads.

The multipart upload option in the above command takes a JSON structure that describes the parts of the multipart upload that should be reassembled into the complete file. In this example, the file:// prefix is used to load the JSON structure from a file in the local folder named mpustruct.

mpustruct:

{
  "Parts": [
    {
      "ETag": "e868e0f4719e394144ef36531ee6824c",
      "PartNumber": 1
    },
    {
      "ETag": "6bb2b12753d66fe86da4998aa33fffb0",
      "PartNumber": 2
    },
    {
      "ETag": "d0a0112e841abec9c9ec83406f0159c8",
      "PartNumber": 3
    }
  ]
}

The ETag value for each part is upload is output each time you upload a part using the upload-part command and can also be retrieved by calling list-parts or calculated by taking the MD5 checksum of each part.

Output:

{
    "ETag": "\"3944a9f7a4faab7f78788ff6210f63f0-3\"",
    "Bucket": "my-bucket",
    "Location": "https://my-bucket.s3.amazonaws.com/multipart%2F01",
    "Key": "multipart/01"
}
