如何以编程方式将文件从本地存储上载到JupyterLab？

import requests

# 定义JupyterLab的URL
jupyterlab_url = "http://localhost:8888"

# 定义要上传的文件路径
file_path = "/path/to/file.txt"

# 打开文件并读取内容
with open(file_path, "rb") as file:
    file_content = file.read()

# 构建上传文件的请求
upload_url = f"{jupyterlab_url}/api/contents/{file_path}"
headers = {"Authorization": "token YOUR_AUTH_TOKEN"}  # 替换为实际的认证令牌
data = {"content": file_content}

# 发送上传文件的请求
response = requests.put(upload_url, headers=headers, data=data)

# 检查上传是否成功
if response.status_code == 201:
    print("文件上传成功！")
else:
    print("文件上传失败！")
