Python: 如何列出每个IBM COS 存储桶的存储桶位置？

Question

我正在使用 Python SDK for IBM Cloud Object Storage and want to loop over all visible buckets and return their location. The issue I am facing is that for some buckets an error The specified bucket does not exist. is returned. According to 。

尽管如此，我如何处理它并至少获得可访问存储桶的位置？这是粗略的 Python 代码：

cos = ibm_boto3.client('s3',
                    ibm_api_key_id=api_key,
                    ibm_service_instance_id=service_instance_id,
                    ibm_auth_endpoint=auth_endpoint,
                    config=Config(signature_version='oauth'),
                    endpoint_url=service_endpoint)


# Call COS to list current buckets
response = cos.list_buckets()

# Get a list of all bucket names from the response
buckets = [bucket['Name'] for bucket in response['Buckets']]
print(response)

for bucketname in buckets:
   print(bucketname, cos.get_bucket_location(Bucket=bucketname)['LocationConstraint'])

Answer 1

我现在使用了这个解决方法：

def locations(buckets):
   locs={}
   for b in buckets:
      try: 
         locs[b]=cos.get_bucket_location(Bucket=b)['LocationConstraint']
      except: 
         locs[b]=None
         pass
   return locs

它试图获取位置。如果失败，将分配 None，当转换为 JSON.

时，它会很好地转换为 null
