Of a non-200 status or a xmlrpclib.Frontier::Client - issue Frontier XML RPC requests to a server SYNOPSIS use Frontier::Client The exception will be the relevant TwistedĮrror in the case of a problem with the underlying connection (for example,Ī timeout), IOError containing the status and message in the case Which will be called back with the result. Which accepts a method name and a variable argument list (but no namedĪrguments, as these are not supported by XML-RPC). Having a proxy object, one can just call the callRemote method, When an XML-RPC service is described, the URL to that service The interface Twisted presents to XML-RPC client is that of a proxyĬonstructor for the object receives a URL: it must be an HTTP or HTTPS No magic _getattr_ : calls must be made by an explicit XML-RPC calls, then it will have to be given explicitly. There are two major deviationsįrom the xmlrpclib way which should be noted: Taking features from both, as appropriate. XML-RPC clients in Twisted are meant to look as something which will beįamiliar either to xmlrpclib or to Perspective Broker users, Method’s documentation string is used instead.

Theįollowing example has two methods published via XML-RPC, add(a, b) and echo(x). You to return results that can’t be calculated immediately, such as database queries.Īre Resource objects, and they can thus be published using a Site. InĪddition, XML-RPC published methods can return Deferred instances whose results are one of the above. Instances (all of these are the same as the respective classes in xmlrpclib. They can also raise exceptions or return Failure instances to indicate anĮrror has occurred, or Binary, Boolean or DateTime Types, such as strings, lists and so on (just return a regular python Methods published via XML-RPC can return all the basic XML-RPC The result is what will be returned to the clients. The methods’Īrguments determine what arguments it will accept from XML-RPC clients. You then create methods beginning with xmlrpc_. Making a server is very easy - all you need to do is inherit from.
