A proxy that modifies some data when connecting to Box using rclone.
The box_proxy.py script now exposes a unified command interface with multiple sub-commands:
python box_proxy.py serve --config config.json
This command launches the proxy, remembers the dynamically assigned port under ~/.box_proxy/port, and rewrites existing rclone Box entries so that they use the local proxy endpoints.
python box_proxy.py authorize <boxentryname> --config config.json
boxentryname is the name for the entry that will be written into rclone.conf. The command registers a handler for the boxlogin:// scheme (on Linux systems via xdg-mime). On Windows the handler is added to the registry under HKEY_CURRENT_USER\Software\Classes\boxlogin with the following structure:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\boxlogin]
@="URL:boxlogin Protocol"
"URL Protocol"=""
[HKEY_CURRENT_USER\Software\Classes\boxlogin\shell\open\command]
@="\"C:\\Path\\to\\python.exe\" \"C:\\Path\\to\\box_proxy.py\" _boxlogin \"%1\""
After associating the handler, the command invokes rclone authorize box ..., waits for the browser-based login flow to complete, parses the resulting token, and finally stores it in rclone.conf via rclone config create.
The proxy also exposes an internal sub-command that acts as the target of the boxlogin:// scheme:
python box_proxy.py _boxlogin "boxlogin://login?..."
This forwards the authorization result to the running proxy server. The command is intended to be executed automatically by the OS after the handler registration performed in step 2.
box_redirect.js is kept for reference; the new _boxlogin command supersedes its role in most environments.
