Disconnect TwythonStreamer on DELETE rest api call

Question

Here is my wrapper on TwythonStreamer:

from twython import TwythonStreamer

class Twitter_talker(TwythonStreamer):
    def __init__(self):
        super(Twitter_talker, self).__init__(<my credentials here...>)
    def on_success(self, data):
        self.disconnect()
        print data

    def on_error(self, status_code, data):
        print status_code
        self.disconnect()

Here is my call to get statuses from twitter:

class Tweet_Handler(tornado.web.RequestHandler):
def get(self):
    stream = Twitter_talker()
    stream.statuses.filter(track='badminton')

I create this stream looking for "badminton" on GET REST API call to my web server. And though its not coded, but it will be a async call, meaning i will return a response like "1" indicating stream was created successfully.

How do I self.disconnect when i receive a DELETE REST API call with value "badminton" ?

Answer 1

您的DELETE处理程序将具有与GET处理程序不同的self （始终为每个请求实例化一个新的RequestHandler 。您需要将GET处理程序存储在某个位置，也许是将关键字映射到一组处理程序的全局字典（不要忘记）删除on_finish ），请看Tornado 聊天演示以及它如何管理服务员集合。

Use a class attribute to hold a dictionary of Twitter Talkers.

class Tweet_Handler(tornado.web.RequestHandler):

    requests = {}

    def get(self):
        stream = Twitter_talker()
        stream.statuses.filter(track='badminton')
        Tweet_Handler.requests['badminton'] = stream

    def delete(self):
        value = self.get_argument("value")
        if value in Tweet_Handler.requests:
             Tweet_Handler.requests[value].disconnect()
             del Tweet_Handler.requests[value]
