Usage

The plugin provides five powerful tools for interacting with Alibaba Cloud OSS:

1. Upload File to OSS (upload_file)

Dedicated tool for uploading files to Alibaba Cloud OSS.

• Parameters:
  • file: The local file to upload (required)
  • directory: First-level directory under the bucket (required)
  • directory_mode: Optional directory structure mode (default: no_subdirectory)
    • no_subdirectory: Store directly in specified directory
    • yyyy_mm_dd_hierarchy: Store in date-based hierarchical structure

  • filename_mode: Optional filename composition mode (default: filename)
    • filename: Use original filename
    • filename_timestamp: Use original filename plus timestamp
  • sign_expired: Signature expiration time in seconds (optional, default 3600 seconds)
    • Controls how long the generated URL signature remains valid
    • Only effective for private access with complete account permissions
    • After expiration, the URL will no longer provide access to the file

2. Multi Upload Files to OSS (multi_upload_files)

Dedicated tool for uploading multiple files to Alibaba Cloud OSS simultaneously.

• Parameters:
  • files: The local files to upload (required)
  • directory: First-level directory under the bucket (required)

  • sign_expired: Signature expiration time in seconds (optional, default 3600 seconds)
    • Controls how long the generated URL signature remains valid
    • Only effective for private access with complete account permissions
    • After expiration, the URL will no longer provide access to the files

Example:

# Upload multiple files with default signature expiration (1 hour)
result = multi_upload_files(
    files="file1.jpg;file2.pdf;file3.txt",
    directory="uploads/",
    filename_mode="filename_timestamp"
)

# Upload multiple files with custom signature expiration (3 hours)
result = multi_upload_files(
    files="file1.jpg;file2.pdf;file3.txt",
    directory="uploads/",
    filename_mode="filename_timestamp",
    sign_expired=10800
)

3. Get File by URL (get_file_by_url)

Dedicated tool for retrieving files from Alibaba Cloud OSS using URLs.

• Parameters:
  • file_url: The URL of the file in Alibaba Cloud OSS

4. Batch Get Files by URLs (get_files_by_urls)
