how to publish with kwargs?

[ethe...@mail.fcu.edu.tw]

when i try to send a payload from example like following:

session.publish('com.myapp.hello', [], { text: 'Hello, world' })

but its not working when i try to show the payload with back-end code:

...
def onhello(msg, kwargs=None, details=None):
            print("event for 'onhello' received: {0}, {1}, {2}".format(msg, kwargs, details))

sub = yield self.subscribe(onhello, 'com.example.onhello')
...

it works fine with:

session.publish('com.myapp.hello', ['Hello, world!']);

i just want to know how to publish in kwargs way.

okay i figure it out,
the handler should be:

def onhello(*msg, **kwargs):
            print("event for 'onhello' received: {}, {}".format(msg, kwargs))

 p.s. the topic URI of last post just a copy paste error, not the main problem.

This Python function is fully generic: it can receive any number of
positional or keywords arguments.

Normally, in your case, you would use:

def onhello(text = None)

Using the fully generic form is not something recommended in general,
since it "hides" the concrete arguments you expect.

You can look at all variants for both JS and Python here:
