python - Tornado application/json support -



python - Tornado application/json support -

does tornado back upwards content-type "application/json"?

according phone call stack (assuming stream_request_body = false), method called parse request body parse_body_arguments (httputil.py 662), accepts "application/x-www-form-urlencoded" , "multipart/form-data"

the solution pretty trivial. have json.loads() received body , trust it's proper json-encoded dictionary (if want, grab exception , provide meaningful feedback). can't expect application/json in content-type; during post that'll application/x-www-form-urlencoded.

here sample server:

import json import tornado.httpserver import tornado.ioloop import tornado.web class myhandler(tornado.web.requesthandler): def post(self): info = json.loads(self.request.body.decode('utf-8')) print('got json data:', data) self.write({ 'got' : 'your data' }) if __name__ == '__main__': app = tornado.web.application([ tornado.web.url(r'/', myhandler) ]) http_server = tornado.httpserver.httpserver(app) http_server.listen(8888) print('starting server on port 8888') tornado.ioloop.ioloop.instance().start()

you can test using e.g. curl:

curl -d '{"hello": "world"}' http://localhost:8888/

python json tornado

Php operator `break` doesn't stop while - have weird issue, break doesn't break while loop , maintain rotating. logically should break cycle , set output while ($c++ != 5) { // here curl request, doesn't relevant have removed preg_match("!<.*?>(\s*)[^<>]*?{$to}<!", $resp, $result) ; // echo 'cnt = ' .count($result).'<br>'; if(!count($result)) { $amount = 0; echo 'sleep called'; sleep(4); exit; continue; } else { $amount = trim(@$result[1]); $amount = round($amount + $amount * $exchange_ratio, $precision); echo 'break happen<br>'; break; } } so output cnt = 2 break happen cnt = 0 sleep called so skipped break , maintain rotating. how so? edit works fine on localhost issue php version? ...
