Hi,
I am developing an middleware XMLRPC Server. It connects with a mail
server and provides and XMLRPC interface to read and send mail.
Is there any way to return the result of the xmlrpc method in deferred's
callback?
Is there any way to return a deferred object inside the xmlrpc method?
Is it a good solution using asynchronous chunks (deferreds) inside a
synchronous protocol as it is XML-RPC (HTTP)?
I use this pattern on the server side
def xmlrpc_getStuff(self, stuff):
def fail(_):
print "Oh dear!"
return False
def returnStuff(dbResult):
otherstuff = doStuffWith(dbResult)
return otherStuff
return self.db.getStuff(stuff).addCallbacks(returnStuff, fail)
And this one on the client side
def checkKey(stuff):
def fail(_):
return False
def good(stuff):
return stuff
return Proxy(xmlServer, allowNone=True).callRemote('getStuff',
stuff).addCallbacks(good, fail)
There are better ways depending on what you're really doing..
