You cannot use return with a value to exit a generator in Python 2, or Python 3.0 – 3.2. You need to use yield plus a return without an expression: if response.error: self.error(“Error while retrieving the status”) self.finish() yield error return In the loop itself, use yield again: for line in response.body.split(“\n”): if line != … Read more

You could call a IOLoop.add_timeout(deadline, callback) that calls the callback at specified deadline timeout (one shot, but you can reschedule), or use the tornado.ioloop.PeriodicCallback if you have a more periodic task. See: http://www.tornadoweb.org/en/stable/ioloop.html#tornado.ioloop.IOLoop.add_timeout Update: some example import datetime def test(): print “scheduled event fired” … if __name__ == “__main__”: http_server = tornado.httpserver.HTTPServer(application) http_server.listen(8888) main_loop = … Read more
If you are running a WSGI application on top of Tornado, then there isn’t a great deal of difference between Tornado and gunicorn in as much as nothing else can happen so long as the WSGI request is being handled by the application in a specific process. In the case of gunicorn because it only … Read more
2017 – Edit: anyone trying to set up React in Gulp for a new project: Just use create-react-app Step I: Add the following to your gulpfile.js somewhere gulp.task(‘apply-prod-environment’, function() { process.env.NODE_ENV = ‘production’; }); Step II: Add it to your default task (or whichever task you use to serve/build your app) // before: // gulp.task(‘default’,[‘browsersync’,’watch’], … Read more
As an alternative to Eloim’s answer, Tornado provides tornado.escape for “Escaping/unescaping HTML, JSON, URLs, and others”. Using it should give you exactly what you want: data = tornado.escape.json_decode(self.request.body)
Delete static_path from the app settings. Then set your handler like: handlers = [ (r’/(favicon\.ico)’, tornado.web.StaticFileHandler, {‘path’: favicon_path_dir}), (r’/static/(.*)’, tornado.web.StaticFileHandler, {‘path’: static_path_dir}), (r”https://stackoverflow.com/”, WebHandler) ]
RequestHandler.request.remote_ip (from RequestHandler’s instance) you can inspect the response like: … class MainHandler(tornado.web.RequestHandler): def get(self): self.write(repr(self.request)) …
You may simulate RequestHandler.send_error method: class MyHandler(tornado.web.RequestHandler): def get(self): self.clear() self.set_status(400) self.finish(“<html><body>My custom body</body></html>”)
I just ran into this and found this issue myself, and using info from this thread came up with the following. I simply took my working stand alone Tornado code (copied from all the examples) and moved the actual starting code into a function. I then called the function as a threading thread. My case … Read more
