|
|
The \module{SimpleXMLRPCServer} module provides a basic server
|
|
framework for XML-RPC servers written in Python. Servers can either
|
|
be free standing, using \class{SimpleXMLRPCServer}, or embedded in a
|
|
CGI environment, using \class{CGIXMLRPCRequestHandler}.
|
|
|
|
\begin{classdesc}{SimpleXMLRPCServer}{addr\optional{,
|
|
requestHandler\optional{, logRequests}}}
|
|
|
|
Create a new server instance. The \var{requestHandler} parameter
|
|
should be a factory for request handler instances; it defaults to
|
|
\class{SimpleXMLRPCRequestHandler}. The \var{addr} and
|
|
\var{requestHandler} parameters are passed to the
|
|
\class{\refmodule{SocketServer}.TCPServer} constructor. If
|
|
\var{logRequests} is true (the default), requests will be logged;
|
|
setting this parameter to false will turn off logging. This class
|
|
provides methods for registration of functions that can be called by
|
|
the XML-RPC protocol.
|
|
\end{classdesc}
|
|
|
|
\begin{classdesc}{CGIXMLRPCRequestHandler}{}
|
|
Create a new instance to handle XML-RPC requests in a CGI
|
|
environment. \versionadded{2.3}
|
|
\end{classdesc}
|
|
|
|
\begin{classdesc}{SimpleXMLRPCRequestHandler}{}
|
|
Create a new request handler instance. This request handler
|
|
supports \code{POST} requests and modifies logging so that the
|
|
\var{logRequests} parameter to the \class{SimpleXMLRPCServer}
|
|
constructor parameter is honored.
|
|
\end{classdesc}
|
|
|
|
|
|
\subsection{SimpleXMLRPCServer Objects \label{simple-xmlrpc-servers}}
|
|
|
|
The \class{SimpleXMLRPCServer} class is based on
|
|
\class{SocketServer.TCPServer} and provides a means of creating
|
|
simple, stand alone XML-RPC servers.
|
|
|
|
\begin{methoddesc}[SimpleXMLRPCServer]{register_function}{function\optional{,
|
|
name}}
|
|
Register a function that can respond to XML-RPC requests. If
|
|
\var{name} is given, it will be the method name associated with
|
|
\var{function}, otherwise \code{\var{function}.__name__} will be
|
|
used. \var{name} can be either a normal or Unicode string, and may
|
|
contain characters not legal in Python identifiers, including the
|
|
period character.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}[SimpleXMLRPCServer]{register_instance}{instance}
|
|
Register an object which is used to expose method names which have
|
|
not been registered using \method{register_function()}. If
|
|
\var{instance} contains a \method{_dispatch()} method, it is called
|
|
with the requested method name and the parameters from the request;
|
|
the return value is returned to the client as the result. If
|
|
\var{instance} does not have a \method{_dispatch()} method, it is
|
|
searched for an attribute matching the name of the requested method;
|
|
if the requested method name contains periods, each component of the
|
|
method name is searched for individually, with the effect that a
|
|
simple hierarchical search is performed. The value found from this
|
|
search is then called with the parameters from the request, and the
|
|
return value is passed back to the client.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}{register_introspection_functions}{}
|
|
Registers the XML-RPC introspection functions \code{system.listMethods},
|
|
\code{system.methodHelp} and \code{system.methodSignature}.
|
|
\versionadded{2.3}
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}{register_multicall_functions}{}
|
|
Registers the XML-RPC multicall function system.multicall.
|
|
\end{methoddesc}
|
|
|
|
Example:
|
|
|
|
\begin{verbatim}
|
|
class MyFuncs:
|
|
def div(self, x, y) : return div(x,y)
|
|
|
|
|
|
server = SimpleXMLRPCServer(("localhost", 8000))
|
|
server.register_function(pow)
|
|
server.register_function(lambda x,y: x+y, 'add')
|
|
server.register_introspection_functions()
|
|
server.register_instance(MyFuncs())
|
|
server.serve_forever()
|
|
\end{verbatim}
|
|
|
|
\subsection{CGIXMLRPCRequestHandler}
|
|
|
|
The \class{CGIXMLRPCRequestHandler} class can be used to
|
|
handle XML-RPC requests sent to Python CGI scripts.
|
|
|
|
\begin{methoddesc}{register_function}{function\optional{, name}}
|
|
Register a function that can respond to XML-RPC requests. If
|
|
\var{name} is given, it will be the method name associated with
|
|
function, otherwise \var{function.__name__} will be used. \var{name}
|
|
can be either a normal or Unicode string, and may contain
|
|
characters not legal in Python identifiers, including the period
|
|
character.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}{register_instance}{instance}
|
|
Register an object which is used to expose method names
|
|
which have not been registered using \method{register_function()}. If
|
|
instance contains a \method{_dispatch()} method, it is called with the
|
|
requested method name and the parameters from the
|
|
request; the return value is returned to the client as the result.
|
|
If instance does not have a \method{_dispatch()} method, it is searched
|
|
for an attribute matching the name of the requested method; if
|
|
the requested method name contains periods, each
|
|
component of the method name is searched for individually,
|
|
with the effect that a simple hierarchical search is performed.
|
|
The value found from this search is then called with the
|
|
parameters from the request, and the return value is passed
|
|
back to the client.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}{register_introspection_functions}{}
|
|
Register the XML-RPC introspection functions
|
|
\code{system.listMethods}, \code{system.methodHelp} and
|
|
\code{system.methodSignature}.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}{register_multicall_functions}{}
|
|
Register the XML-RPC multicall function \code{system.multicall}.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}{handle_request}{\optional{request_text = None}}
|
|
Handle a XML-RPC request. If \var{request_text} is given, it
|
|
should be the POST data provided by the HTTP server,
|
|
otherwise the contents of stdin will be used.
|
|
\end{methoddesc}
|
|
|
|
Example:
|
|
|
|
\begin{verbatim}
|
|
class MyFuncs:
|
|
def div(self, x, y) : return div(x,y)
|
|
|
|
|
|
handler = CGIXMLRPCRequestHandler()
|
|
handler.register_function(pow)
|
|
handler.register_function(lambda x,y: x+y, 'add')
|
|
handler.register_introspection_functions()
|
|
handler.register_instance(MyFuncs())
|
|
handler.handle_request()
|
|
\end{verbatim}
