Web services can be generally regarded as functions or functionality of applications or systems exposed over the Web using standardised message formats and typically interfaced to other software using traditional APIs, although "message-centric" usage of such services is also possible and may be favoured by certain technologies.
python-json-rpc The specification website includes a Python implementation.
JsonUtils is another library that supports JSON-RPC.
JSON-WSP is another JSON based webservice protocol. It is inspired by JSON-RPC but designed with a JSON based description format (like WSDL in SOAP). For the time being there is only a Python based implementation, but a PHP implementation is in progress and will also be openly available.
- Ladon is a multiprotocol approach to creating a webservice. See below, in the SOAP section, for more information.
pfacka/jsonwsp is another JSON-WSP server and client implementation.
SOAP is a Web services technology favoured in certain environments. The following projects seek to support SOAP and related technologies such as WSDL:
suds (on PyPi) - Suds is a lightweight SOAP python client that provides a service proxy for Web Services. This is the best maintained fork of the original Suds project by Jeff Ortel, and it's compatible with Python 2 and 3.
spyne (on PyPi) - Spyne, formerly known as Soaplib, is transport and architecture agnostic RPC library that focuses on exposing services with a well-defined API using popular protocols, including SOAP. It's well maintained, and compatible with Python 2 and mostly 3.
osa - osa is a fast/slim easy to use SOAP python client library.
Python Web Services and Zolera Soap Infrastructure ((ZSI on PyPi) provides both client and server SOAP libraries. It was very popular, but it's a dead project (last release 2007) without any Python 3 support.
The first popular and largely standardised Web services technology was XML-RPC, supported in Python by the following libraries:
- xmlrpclib - found in the standard library
More in common with the message-centric usage of SOAP, XMPP - an Internet standard which provides the foundation for the Jabber instant messaging technology - could be used as a Web services protocol. See PythonXml for details of suitable projects.
