(Python)如何使用没有SDK的API将文件上传到dropbox文件夹

import requests

def upload_to_dropbox(file_path, access_token, destination_path):
    url = "https://content.dropboxapi.com/2/files/upload"
    headers = {
        "Authorization": "Bearer " + access_token,
        "Content-Type": "application/octet-stream",
        "Dropbox-API-Arg": '{"path": "' + destination_path + '", "mode": "add", "autorename": true, "mute": false}'
    }

    with open(file_path, "rb") as file:
        data = file.read()

    response = requests.post(url, headers=headers, data=data)
    if response.status_code == 200:
        print("File uploaded successfully.")
    else:
        print("File upload failed.")

# 使用示例
file_path = "path/to/local/file.txt"  # 本地文件路径
access_token = "your_access_token"  # 你的Dropbox应用程序访问令牌
destination_path = "/path/to/destination/file.txt"  # 目标文件在Dropbox中的路径

upload_to_dropbox(file_path, access_token, destination_path)
