Transfer.sh Client

transfersh-client is a Python library designed to upload files to transfer.sh servers. It supports both public transfer.sh instances and self-hosted servers, provided that the server is already running.

Features

• File Uploading: Upload files to a transfer.sh server using HTTP PUT requests.
• Authentication: Supports HTTP Basic Authentication for secured servers.
• Filename Management: Option to use original filenames or generate random filenames using UUIDs, with optional preservation of file extensions.
• Upload Constraints: Set maximum number of downloads and expiration days for uploaded files.
• Flexible Host Configuration: Supports various host formats, including local IPs with ports and HTTP/HTTPS protocols.

Installation

Install python-transfer-sh via pip:

pip install python-transfer-sh

Usage

Importing the Library

from transfer_sh_client.manager import TransferManager

Initializing TransferManager

host = "https://some.transfer.sh"  # Examples: 'http://localhost:8080', 'https://192.168.1.100:8443'
username = "admin"                         # Optional
password = "X9kmP2vL5nQ8j"                 # Optional

manager = TransferManager(host, username, password)

• host: The transfer.sh server's URL or IP address, including the protocol (http or https) and port if necessary.
  • Examples:
    • http://localhost:8080
    • https://192.168.1.100:8443
    • https://some.transfer.sh
• username: (Optional) Username for HTTP Basic Authentication.
• password: (Optional) Password for HTTP Basic Authentication.

Uploading a File

file_to_upload = "path/to/your/file.txt"

try:
    download_link = manager.upload(
        file_path=file_to_upload,
        max_downloads=3,               # Optional: Maximum number of downloads
        max_days=7,                    # Optional: Number of days the file will be available
        generate_random_filename=True, # Optional: Generate a random filename
        save_ext=True                  # Optional: Preserve the file extension if generating a random filename
    )
    print("File uploaded successfully!")
    print("Download link:", download_link)
except Exception as e:
    print("Upload failed:", e)

Parameters

• file_path (str): Path to the local file you want to upload.
• max_downloads (int, optional): Maximum number of times the file can be downloaded. Defaults to None (no limit).
• max_days (int, optional): Number of days the file will remain available on the server. Defaults to None (no expiration).
• generate_random_filename (bool, optional): If set to True, the file will be uploaded with a randomly generated UUID filename. If False, the original filename will be used. Defaults to False.
• save_ext (bool, optional): If generate_random_filename is True, setting this to True will preserve the original file's extension. If False, the file will be uploaded without an extension. Defaults to True.

Docker-compose for transfer.sh example

You can use this template as example of transfer.sh server:

version: '3'
services:
  transfer:
    container_name: transfer.sh
    image: dutchcoders/transfer.sh:latest
    ports:
      - "192.168.1.96:8080:8080" # change to your ip and port, if you have nginx you can use 443 port
    volumes:
      - /path/to/transfer/data:/data
    environment:
      - PURGE_DAYS=7
      - MAX_UPLOAD_SIZE=2147483648  # 2GB
      - RATE_LIMIT=100
      - HTTP_AUTH_USER=admin # Optional
      - HTTP_AUTH_PASS=some_password  # Optional
    command: >
      --provider local
      --basedir /data
      --temp-path /data/temp
      --log /data/transfer.log
    restart: unless-stopped
    networks:
      - transfer_net

networks:
  transfer_net:
    driver: bridge

Example Scenarios

1. Uploading with Original Filename

download_link = manager.upload(
    file_path="document.pdf"
)
print("Download link:", download_link)

2. Uploading with Random Filename and Preserved Extension

download_link = manager.upload(
    file_path="image.png",
    generate_random_filename=True,
    save_ext=True
)
print("Download link:", download_link)

3. Uploading with Random Filename without Extension and Constraints

download_link = manager.upload(
    file_path="archive.zip",
    generate_random_filename=True,
    save_ext=False,
    max_downloads=5,
    max_days=10
)
print("Download link:", download_link)

Supported Host Formats

The host parameter accepts various formats to accommodate different server configurations:

• Localhost with Port:

  • http://localhost:8080
  • https://localhost:8443

• Local IP with Port:

  • http://192.168.1.100:8080
  • https://192.168.1.100:8443

• Domain with Protocol:

  • http://some.transfer.sh:8080
  • https://some.transfer.sh

Ensure that the transfer.sh server you are uploading to is running and configured to handle HTTP PUT requests.

Error Handling

The upload method raises exceptions in the following scenarios:

• FileNotFoundError: If the specified file does not exist.
• RuntimeError: If the upload fails due to network issues, authentication errors, or server-side problems.

Example:

try:
    download_link = manager.upload("nonexistent.file")
except FileNotFoundError as fnf_error:
    print(fnf_error)
except RuntimeError as runtime_error:
    print(runtime_error)

Dependencies

transfersh-client relies on the requests library, which is automatically installed when you install transfersh-client via pip.

If you need to install it manually:

pip install requests
