Serve files from dropbox over http(s)

Since October 3, 2016 Dropbox stopped serving html files with the correct text/html content-type header. .html and .json files are now served with a content-disposition header which makes the browser download the file instead of render it.

This created issues for me since I am used to storing output of various scripts into my /Public directory and view them on desktop/mobile and/or share them with others.

dboxserver uses Dropbox API to fetch and serve files over http(s).

CLIENT_ID="REMOVED" CLIENT_SECRET="REMOVED" ACCESS_TOKEN="REMOVED" go run server.go -hostname "db.sajalkayan.com"

You need to create an app at the Dropbox developer portal. CLIENT_ID - "App key" CLIENT_SECRET - "App secret" ACCESS_TOKEN - Allow implicit grant and generate an access token. -hostname - If configured the server listens over https on :443 and gets certificate from Let's Encrypt otherwise it listens over http on :8889. folder - Defaults to /Public . The Dropbox folder you want to expose.

1. Caches objects in memory forever.
2. Invalidates cache as soon as anything is changed in the monitored folder.
3. Only cache objects lower than specified size (not yet implemented).
4. Tries to fix content-type if Dropbox falls back to application/octet-stream - example for json

1. Code cleanup - Currently this is result of couple of hours hack.
2. Test cases
3. Bug fixes
