PyAMF pour GAE (Google App Engine), peu d'aide nécessaire:

Question

# I need this behaviour: 
# 1) check if the service from flash is included in the services array 
# 2) if not, return false or an error | if yes, step 3 
# 3) combine the rootPath('app.controllers') with the service name('sub1.sub2.sub3.function_name') 
# 4) and then get the function('function_name') from the 'app.controllers.sub1.sub2.sub3.function_name' package 
# 5) then run the function the way that would be done normally by pyAMF 

from app.controllers.users.login import login 
from app.controllers.users.logout import logout 
from app.controllers.profiles.edit import edit as profilesEdit 
from app.controllers.profiles.new import new as profilesNew 
from app.controllers.invitations.invite import invite as invitationsInvite 
from app.controllers.invitations.uninvite import uninvite as invitationsUninvite 

def main(): 
    services = { 
    'users.login': login, 
    'users.logout': logout, 
    'profiles.edit': profilesEdit, 
    'profiles.new': profilesNew, 
    'invitations.invite': invitationsInvite, 
    'invitations.uninvite': invitationsUninvite 
    } 

    gateway = WebAppGateway(services, logger=logging, debug=True) 
    application = webapp.WSGIApplication([('/', Init), 
             ('/ajax', gateway)], debug=True) 
    run_wsgi_app(application) 

insted de ce je voudrais:

def main(): 
    services = [ 
    'users.login', 
    'users.logout', 
    'profiles.edit', 
    'profiles.new', 
    'invitations.invite', 
    'invitations.uninvite', 
    'sub1.sub2.sub3.function_name' 
    ] 
    rootPath = 'app.controllers' 

    gateway = WebAppGateway(services, rootPath, logger=logging, debug=True) 
    application = webapp.WSGIApplication([('/', Init), 
             ('/ajax', gateway)], debug=True) 
    run_wsgi_app(application) 

# and then I would extend the WebAppGateway in some way to have this behaviour: 
# 1) check if the service from flash is included in the services array 
# 2) if not, return false or an error | if yes, step 3 
# 3) combine the rootPath('app.controllers') with the service name('sub1.sub2.sub3.function_name') 
# 4) and then get the function('function_name') from the 'app.controllers.sub1.sub2.sub3.function_name' package 
# 5) then run the function the way that would be done normally by pyAMF 

est-ce possible? merci

Résolu la nuit dernière! merci @njoyce
