Python版Dropbox API：如何访问团队及个人文件

问题背景 #

作为Dropbox商业版团队成员，希望通过API实现与网页端登录相同的体验，查看个人及团队文件/文件夹。已使用以下代码完成OAuth2认证：

dropbox.DropboxOAuth2FlowNoRedirect(
    settings.DROPBOX_APP_KEY, 
    settings.DROPBOX_APP_SECRET,
    token_access_type="offline",
    scope=[
        "account_info.read",
        "file_requests.read",
        "file_requests.write",
        "files.content.read",
        "files.content.write",
        "files.metadata.read",
        "files.metadata.write",
        "files.team_metadata.read",
        "files.team_metadata.write",
        "sharing.read", 
        "sharing.write",
        "team_data.content.read",
        "team_data.content.write",
        "team_data.governance.read",
        "team_data.governance.write",
        "team_data.member",
        "team_data.team_space",
    ],        
)

但调用dbx.file_list_folders()时出现错误：

This API function operates on a single Dropbox account, but the OAuth 2 access token you provided is for an entire Dropbox Business team. Since your API app key has team member file access permissions, you can operate on a team member's Dropbox by providing the "Dropbox-API-Select-User" HTTP header or "select_user" URL parameter to specify the exact user.

已知可通过dbx_team.as_user("YOUR_TEAM_MEMBER_ID")切换身份，但不清楚如何获取YOUR_TEAM_MEMBER_ID。

解决方案 #

1. 获取当前授权用户的Team Member ID #

无需遍历所有团队成员，直接通过DropboxTeam客户端调用接口获取自身的Team Member ID：

import dropbox

# 初始化团队客户端
dbx_team = dropbox.DropboxTeam(ACCESS_TOKEN)

# 获取当前授权用户的团队成员信息
current_member = dbx_team.team_members_get_current()
member_id = current_member.profile.team_member_id

2. 访问个人文件/文件夹 #

使用as_user()方法切换到个人身份，即可调用个人文件相关API，实现和网页端访问个人空间一致的逻辑：

# 切换到个人用户身份
dbx_user = dbx_team.as_user(member_id)

# 列出个人根目录文件
personal_files = dbx_user.files_list_folder("")
for entry in personal_files.entries:
    print(entry.name)

3. 访问团队空间文件/文件夹 #

直接使用DropboxTeam客户端调用团队文件相关API，即可访问团队空间内容：

# 获取团队文件夹列表
team_folders = dbx_team.team_folder_list()

# 遍历团队文件夹并列出内容
for folder in team_folders.team_folders:
    print(f"团队文件夹：{folder.name}")
    # 列出该团队文件夹下的文件
    team_files = dbx_team.files_list_folder(f"/{folder.team_folder_id}")
    for entry in team_files.entries:
        print(f"  - {entry.name}")
