Tmpfiles Upload

Upload files (images, PDFs, documents) to tmpfiles.org and send download links via messaging platforms. Use when: (1) User asks to send screenshots/files via Feishu/other platforms, (2) Direct file upload to messaging platform fails, (3) User needs a temporary file sharing solution with auto-expiring links.

tmpfiles.org File Upload

Upload files to tmpfiles.org (temporary file hosting) and get a download link.

When to Use

• Sending screenshots to Feishu when direct upload fails
• Sharing files temporarily (links expire after ~1 hour)
• Quick file sharing without authentication

Upload Script

python

import requests

def upload_to_tmpfiles(file_path):
    """Upload file to tmpfiles.org and return download URL"""
    with open(file_path, 'rb') as f:
        r = requests.post('https://tmpfiles.org/api/v1/upload', files={'file': f})
        data = r.json()
        if data.get('status') == 'success':
            # Replace org/ with org/dl/ for direct download
            return data['data']['url'].replace('org/', 'org/dl/')
        raise Exception(f"Upload failed: {data}")
