A TUS-based file transfer tool with chunked upload/download support

Project description

ETransfer

面向大文件场景的高性能传输工具,基于 TUS 协议。支持断点续传、切片上传下载、流式中继(上传未完成即可下载)、阅后即焚,适用于 AI 训练数据集、模型权重等大文件的可靠分发。

特性

  • 基于 TUS 协议的断点续传,网络中断自动恢复
  • 切片上传/下载,支持部分下载(流式中继)
  • 阅后即焚 / TTL 过期 / 永久保存三种文件策略
  • 存储配额管理,超限自动等待并恢复
  • 多 IP 负载均衡,自动选择最优节点
  • OIDC 用户系统,基于角色/群组的配额控制
  • CLI + GUI + Python API

安装

pip install etransfer

如需部署服务端(含 SQLAlchemy async 依赖):

pip install "etransfer[server]" --only-binary greenlet

--only-binary greenlet 确保只安装预编译 wheel,避免 Windows 等平台上的 C 编译问题。

快速开始

# 配置服务器地址
etransfer setup your-server

# 登录(如果服务器启用了 OIDC)
etransfer login

# 上传
etransfer upload ./model-weights.bin

# 阅后即焚上传
etransfer upload ./dataset.tar.gz --retention download_once

# 下载
etransfer download <file_id> -o ./output/

# 文件列表
etransfer list

# 服务器信息
etransfer info

进阶使用(Python API)

from etransfer.client.tus_client import EasyTransferClient
from etransfer.client.downloader import ChunkDownloader

# 上传
with EasyTransferClient("http://your-server:8765", token="your-token") as client:
    uploader = client.create_uploader("./large-model.bin", retention="download_once")
    uploader.upload(wait_on_quota=True)
    file_id = uploader.url.split("/")[-1]

# 下载
downloader = ChunkDownloader("http://your-server:8765", token="your-token")
downloader.download_file(file_id, "./output/large-model.bin")
