wsloader: Webservice Loader

Webservice Loader (wsloader) is a WSGI application and protocol to allow exposing native Python interfaces as REST-like webservices without writing any HTTP/web-service specific code to expose a new service.

Objectives

The objectives of wsloader are:

1. Minimal/Zero extra code and configuration to expose a Python module/class as a webservice
2. Clean separation of webservice delivery mechanism and service implementation
3. Full encapsulation of webservice protocols and mechanisms for authentication, authorisation, serialisation, end-point discovery and loading, logging and load balancing

Features

Currently wsloader supports the following features:

• loading any Python module/class as a service
• handling of service independent request and response marshalling via JSON
• automatic URL creation based on the module path (can be overridden)
• automatic enforcing of GET and POST methods for read and write endpoints
• proper HTTP error responses for service invocation failures
• high-performance application loading and state management
• apache error log access to module code via sys.stderr

See the Overview for more details and installation instructions, or see QuickStart for a short example on how to create a new service with wsloader.
