Create a bucket
bucket = cos_client.create_bucket('your_bucket_name')
Upload a file
bucket.upload_file('path/to/your/local/file', 'object_name_in_cos')

3、2 Downloading Data

To download data from your COS bucket, you can use the following methods:

1、Alibaba Cloud Console: Log in to the Alibaba Cloud console, navigate to the COS service, and select the bucket you want to download data from. Then, click the "Download" button and follow the prompts to download your files.

2、SDKs: Similar to uploading, you can use SDKs to download data programmatically. Here's an example in Python:

from cos_sdk.v5 import CosClient
Initialize the client
cos_client = CosClient('your_access_key_id', 'your_access_key_secret', 'your_endpoint')
Create a bucket
bucket = cos_client.get_bucket('your_bucket_name')
Download a file
bucket.download_file('object_name_in_cos', 'path/to/your/local/file')

4、Managing Access Control

Alibaba Cloud Object Storage (COS) provides robust access control features, allowing you to manage access to your data. You can set up access control policies to control who can access your bucket and objects.

4、1 Access Control Policies

1、Bucket Policies: You can set bucket policies to control access to the entire bucket.

2、Object Access Control List (ACL): You can set ACLs to control access to individual objects within the bucket.

3、IAM Roles: You can use IAM roles to grant access to specific users or groups.

4、2 Setting Up Access Control

To set up access control, follow these steps:

1、Log in to the Alibaba Cloud console.

2、Navigate to the COS service and select the bucket you want to manage.

3、Click the "Access Control" tab and configure the access control policies as per your requirements.
