如何对Bluemix S3 Lite进行认证?

问题描述

我正在尝试通过以下代码将S3 API与Bluemix对​​象存储一起使用:

I'm trying to use S3 API with Bluemix object storage using the following code:

import boto3, pprint, sys;
s3 = boto3.Session().client(
    service_name="s3",
    region_name="us-geo",
    endpoint_url="https://s3-api.us-geo.objectstorage.softlayer.net",
    aws_access_key_id="auto-generated-apikey-<redacted>",
    aws_secret_access_key="<redacted>");
pprint.pprint(s3.list_buckets());

但不断出现AccessDenied错误:

but keep getting AccessDenied error:

<Error>
    <Code>AccessDenied</Code>
    <Message>Access Denied</Message>
    <Resource></Resource>
    <RequestId><redacted></RequestId>
    <httpStatusCode>403</httpStatusCode>
</Error>

我从服务凭据"选项卡中获取了aws_access_key_id和aws_secret_access_key.我为AWS S3使用了类似的代码，并且可以正常工作.我想念什么?

I took aws_access_key_id and aws_secret_access_key from the "Service Credentials" tab. I used similar code for AWS S3, and it worked. What am I missing?

推荐答案

启用了IAM的cos使用稍微不同的语法来创建客户端，而boto3库的fork支持这种语法.

The IAM-enabled cos uses a slightly different syntax for client creation that is supported by a fork of the boto3 library.

以下是文档中的示例: https://console.bluemix.net/docs/services/cloud-object-storage/libraries/python.html

Here’s an example in the docs: https://console.bluemix.net/docs/services/cloud-object-storage/libraries/python.html
