Accessing 'x-forwarded-for' request header from Bokeh app?

[joseph.yang]

I’m wondering if it’s possible for a Bokeh app to identify user IP address. In other Python web-frameworks, I can access to HTTP request headers including ‘x-forwarded-for’ but not too clear if this would be possible for Bokeh?

I have a simple weather data downloader app (https://weatherdownloader.oikolab.com) that uses Bokeh as a frontend UI and a librarian asked about allowing users accessing the service from the library WiFi without signing up. They do this for some other data services so am wondering how I would implement this.

Any help would be greatly appreciated!

Thanks,

You can define a request hook handler to access the entire original HTTP request:

https://docs.bokeh.org/en/latest/docs/user_guide/server/app.html#request-handler-hooks

The dict returned by the function you provide will be made available to the session as the token_payload.

That’s perfect - thank you very much for the help @Bryan!
