python-3.x - 将 GLACIER 对象恢复到 S3 标准层

Question

我正在编写一个可以从 Glacier 恢复对象的代码。我们将使用的层级是标准。
我正在关注这个文档:
Bot3 documentation on client.restor_object
另请参阅来自 github 帐户的此示例:https://github.com/boto/boto3/issues/380
此代码在没有RestoreRequest 中的Tier 选项的情况下工作。

 import boto3

s3 = boto3.resource('s3')
bucket = s3.Bucket('datasets-imported-imdb')
for obj_sum in bucket.objects.all():
    if obj_sum.key == 'testfile.mov':
        print(f'file being restored {obj_sum.key}')
        resp = bucket.meta.client.restore_object(
            Bucket=obj_sum.bucket_name,
            Key=obj_sum.key,
            RestoreRequest={'Days': 1,'Tier': 'Standard'}    
        )
    else:
        print(f'file not being restored {obj_sum.key}')

这是回溯:

Traceback (most recent call last):
  File "test.py", line 8, in <module>
    resp = bucket.meta.client.restore_object(
  File "/home/alex_anadon/.local/lib/python3.8/site-packages/botocore/client.py", line 357, in _api_call
    return self._make_api_call(operation_name, kwargs)
  File "/home/alex_anadon/.local/lib/python3.8/site-packages/botocore/client.py", line 676, in _make_api_call
    raise error_class(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (MalformedXML) when calling the RestoreObject operation: The XML you provided was not well-formed or did not validate against our published schema

Answer 1

文档显示:

response = client.restore_object(
    Bucket='string',
    Key='string',
    VersionId='string',
    RestoreRequest={
        'Days': 123,
        'GlacierJobParameters': {
            'Tier': 'Standard'|'Bulk'|'Expedited'
        },
    ...

因此，您应该使用:

        resp = bucket.meta.client.restore_object(
            Bucket=obj_sum.bucket_name,
            Key=obj_sum.key,
            RestoreRequest={'Days': 1, 'GlacierJobParameters': {'Tier': 'Standard'}}
        )
