How to do call function after client finishes download from tornado web server?
- by Shabbyrobe
I would like to be able to run some cleanup functions if and only if the client successfully completes the download of a file I'm serving using Tornado.
I installed the firefox throttle tool and had it slow the connection down to dialup speed and installed this handler to generate a bunch of rubbish random text:
class CrapHandler(BaseHandler):
def get(self, token):
crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000))
self.write(crap)
print "done"
I get the following output from tornado immediately after making the request:
done
I 100524 19:45:45 web:772] 200 GET /123 (192.168.45.108) 195.10ms
The client then plods along downloading for about 20 seconds. I expected that it would print "done" after the client was done.
Also, if I do the following I get pretty much the same result:
class CrapHandler(BaseHandler):
@tornado.web.asynchronous
def get(self, token):
crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000))
self.write(crap)
self.finish()
print "done"
Am I missing something fundamental here? Can tornado even support what I'm trying to do? If not, is there an alternative that does?
