Adding custom context to interceptor method

See original GitHub issue

We are implementing a request signing mechanism for one of our customer banking apps and we use combination of OkHttp and Retrofit. The technical flow is supposed to go like this:

A user enters a PIN code in UI
Application constructs a request object (for example, a new payment)
Request object is serialized to underlying raw HTTP body data (byte[])
We sign the byte[] using our signing mechanism based on the PIN code value
We put a special HTTP header in request, with the signature value

We were looking for a way to obtain raw HTTP body data and add HTTP header based on data and PIN code value. The interceptors seemed like a nice way to go around the problem. However, we didn’t find any clean way to pass our signing mechanism context data to the filter - we only get request related information as a part of the “chain” object.

It would be nice to have some clean way to pass custom context to interceptor method…
