Download File with Specific Version-ID from AWS S3 using Python-CodePudding

I'm trying to download file that has many versions from version-enabled bucket. Using the bellow code, it always download the file that has latest version.

s3 = boto3.resource('s3')
bucket = s3.Bucket("mybucket")
bucket.download_file("somefile", "/donwload/path/somefile.txt")

How can I specify which version I want to download for the "somefile" file?

CodePudding user response：

As per the comments, Bucket.download_file has an ExtraArgs parameter, where you can specify additional parameters that are passed down to the Client.get_object function that download_file wraps. From the documentation of get_object, you can see that the relevant argument is VersionId.

s3 = boto3.resource('s3')
bucket = s3.Bucket("mybucket")
bucket.download_file(
    "somefile",
    "/donwload/path/somefile.txt",
    ExtraArgs={"VersionId": "my_version"}
)
