Hi, application block global may cause some probelm, such as app's
performance etc.
before, in other web framework there is simple solution, such as asp.net's
Application['xxx']=xxx
but web.py, with your filter, you can do it, but i thought solution beside
may sth awkward:
import web
def add_global_hook():
g = web.storage({"counter": 0})
def _wrapper(handler):
web.ctx.globals = g
return handler()
return _wrapper
class Test:
def GET(self):
web.ctx.globals.counter += 1
return "<h1>Counter: %d</h1>" % web.ctx.globals.counter
if __name__ == '__main__':
urls = ("/", "Hello")
app = web.application(urls, globals())
app.add_processor(add_global_hook())
app.run()
