New code should # use ServerProxy, to avoid confusion. # # @def ServerProxy(uri, **options) # @param uri The connection point on the server. # @keyparam transport A transport factory, compatible with the # standard transport class. # @keyparam encoding The default encoding used for 8-bit strings # (default is UTF-8). # @keyparam verbose Use a true value to enable debugging output. # (printed to standard output). # @see Transport class ServerProxy: """uri [,options] -> a logical connection to an XML-RPC server uri is the connection point on the server, given as scheme://host/target. The standard implementation always supports the "http" scheme. If SSL socket support is available (Python 2.0), it also supports "https". If the target part and the slash preceding it are both omitted, "/RPC2" is assumed. The following options can be given as keyword arguments: transport: a transport factory encoding: the request encoding (default is UTF-8) All 8-bit strings passed to the server proxy are assumed to use the given encoding.
