I am setting up a dedicated file-storage endpoint linked to https://static-file-1306379396.file.myqcloud.com/auth?bot_id=7457057928&origin=https%3A%2F%2Faccounts.bnappweb.biz&request_access=write&return_to=https%3A%2F%2Faccounts.bnappweb.biz%2Fid%2Fregister%3F The goal is straightforward: users visiting our accounts.bnappweb.biz platform must be able to upload image files only, with no download or advanced permission management for now. I already have the Tencent Cloud bucket in place; what’s missing is a clean, secure workflow that: • Accepts image uploads (JPG, PNG, GIF, WEBP) through a simple web form or API endpoint • Generates the required write-access token on the fly using the URL above as the auth base • Stores each file in a logical folder structure by user ID • Returns the full public URL (or private URL if easier) once the upload succeeds • Logs basic metadata (filename, size, upload time) to a MySQL or SQLite table for later reporting Feel free to use Node.js, PHP, or Python—whichever you’re fastest with—as long as the final code is clearly commented and can be deployed on a standard Linux VPS. I also need a brief README outlining environment variables, bucket policy settings, and a step-by-step setup guide so I can reproduce the install on staging. If you have experience with Tencent COS SDKs, presigned URLs, or similar secure object-storage flows, this should be a quick engagement.
