TOSFS 是一个轻量级的访问TOS 的 Python SDK，用户可以直接在纯Python环境中使用它。

安装

通过如下命令安装TOSFS的最新版本。

pip install tosfs

以下示例为使用TosFileSystem的常用API读写TOS。

import os
from tosfs.core import TosFileSystem

# init TosFileSystem
fs = TosFileSystem(
    endpoint_url="https://{your-tos-endpoint}",
    key="{your-access-key}",
    secret="{your-secret-key}",
    region="{your-region}"
)

local_file_path = "localfile.txt"
remote_file_path = "tos://{your-bucket}/remote_file.txt"

# create a local file to upload
with open(local_file_path, "w") as f:
    f.write("Hello TOSFS.")

# upload to tos
fs.put_file(local_file_path, remote_file_path)
print(f"Uploaded {local_file_path} to {remote_file_path}")

# download from tos
downloaded_file_path = "downloaded_file.txt"
fs.get_file(remote_file_path, downloaded_file_path)
print(f"Downloaded {remote_file_path} to {downloaded_file_path}")

# read content from downloaded local file
with open(downloaded_file_path, "r") as f:
    content = f.read()
    print(f"Content of {downloaded_file_path}: {content}")

# delete tos file
fs.rm(remote_file_path)

# write to tos
with fs.open(remote_file_path, "w") as f:
    f.write("Hello TOSFS.")

# read from tos
with fs.open(remote_file_path, "r") as f:
    tos_content = f.read()
    print(f"Content of {remote_file_path}: {tos_content}")

# clean local files
os.remove(local_file_path)
os.remove(downloaded_file_path)

适用如上代码时，须将endpoint_url、key、secret、region 变量替换为真实的认证信息。并将本地路径和TOS上的路径替换为真实有效的路径，即可成功运行。
