Ibm cloud 如何在Python应用程序中使用COS操作我的VPC（虚拟私有云）实例？（IBM云）

我正试图用Python编写一个算法，从COS（IBM云对象存储）获取一个文件，并将其传输到VPC（虚拟私有云）

我正在使用此代码尝试执行此过程：

 from ibm_vpc import VpcV1
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator
from ibm_cloud_sdk_core import ApiException
import logging


authenticator = IAMAuthenticator("")
service = VpcV1(authenticator=authenticator)


image_file_prototype_model = {}
image_file_prototype_model['href']= "cos://us-south/cos-vm-migration/maquina-windows.qcow2"
logging.getLogger('image_file_prototype_model')



operating_system_identity_model = {}
operating_system_identity_model['name'] = 'ubuntu-16-amd64'

resource_group_identity_model = {}
resource_group_identity_model['id'] = 'bfe34d16c974497aa0b009a430b04de8'


image_prototype_model = {}

image_prototype_model['name'] = 'my-migration-vms'
print(image_prototype_model['name'])
image_prototype_model['resource_group'] = resource_group_identity_model
image_prototype_model['file'] = image_file_prototype_model
image_prototype_model[
    'operating_system'] = operating_system_identity_model

image_prototype = image_prototype_model

response = service.create_image(image_prototype)

但是，我一直在犯这样的错误：

 Traceback (most recent call last):
  File "ibm-vpc.py", line 35, in <module>
    response = service.create_image(image_prototype)
  File "/home/caique/.local/lib/python3.6/site-packages/ibm_vpc/vpc_v1.py", line 2569, in create_image
    response = self.send(request)
  File "/home/caique/.local/lib/python3.6/site-packages/ibm_cloud_sdk_core/base_service.py", line 302, in send
    raise ApiException(response.status_code, http_response=response)
ibm_cloud_sdk_core.api_exception.ApiException: Error: Please check whether the resource you are requesting exists., Code: 400

有人能帮我吗

COS基于S3，有自己的API。列出了所有解决我问题的方法。但是现在，我得到了COS端点的错误。我编辑了上面的问题，你能帮我吗？你是否为你的帐户配置了服务授权，允许VPC从你的COS实例获取图像文件？更多细节：是的，我有服务授权，但不是我创建了服务授权。这是一个问题吗？我会考虑对您的服务配置和/或用户的IAM策略进行故障排除，以确保您对COS中的文件有正确的访问权限。当我尝试CLI

ibmcloud时，它是一个映像创建映像测试——操作系统名称“ubuntu-16-amd64”——文件cos://us-south/cos-vm-migration/maquina-windows.qcow2

，我收到了相同的错误400，错误消息为“请检查您请求的资源是否存在。”-我显然无权访问您的COS实例/存储桶。
