HessianPy

HessianPy is an implementation of Hessian protocol in Python programming language.

Hessian is lightweight binary RPC protocol that is independent from programming language and operating system.

Although HTTP is endorsed as a transport protocol for Hessian any serial two-way byte channel can be used for this purpose. In particular, Hessian can serve as a compact binary serialization format.

HessianPy features

• Implements version 1.0 of Hessian protocol.
• Seting interface class names and call headers by client is not supported.
• Both HTTP and HTTPS are supported as transport protocols.
• The implementation is only client-side but there are stub server implementations that are used for testing.
