File 上传

上传 a local file to a Slack channel:

python3 /mnt/OpenClaw/技能s/slack-extended/scripts/slack_file_上传.py \ --channel C123ABC \ --file /path/to/file.png \ --title "Q4 报告" \ --message "Here's the latest 报告"

Arguments:

--channel (required): Channel ID to 分享 the file in --file (required): Path to the local file --title: Display title (defaults to filename) --message: Comment posted with the file

Troubleshooting missing_scope error: 添加 the required scope (files:write or canvases:write) at API.slack.com, then re安装 the 应用 to the workspace. channel_not_found: Use the channel ID (e.g. C07ABC123), not the channel name. not_authed: 机器人 令牌 may have changed. 检查 ~/.OpenClaw/OpenClaw.json. Canvas edit fAIls: Look up sections first to 获取 valid section_id values. missing_scope for bookmarks: 添加 bookmarks:write and bookmarks:read at API.slack.com, then re安装. Folders not supported: Slack API does not support creating folders — only link bookmarks. Folders can only be 创建d manually in the Slack UI.
