websocket

问题 about websocket protocal ,you can read the detail from here,http://tools.ietf.org/html/rfc6455#section-5.3 in the mask section ,it said: The masking key is a 32-bit value chosen at random by the client. When preparing a masked frame, the client MUST pick a fresh masking key from the set of allowed 32-bit values. The masking key needs to be unpredictable; thus, the masking key MUST be derived from a strong source of entropy, and the masking key for a given frame MUST NOT make it simple for a

问题 I would like to subscribe to some data feed using Websockets using Julia. For example, from the linux terminal, I can successfully get data like this: wscat -c wss://www.bitmex.com/realtime {"op": "subscribe", "args": ["orderBookL2_25:XBTUSD"]} Now in Julia, I cannot find a solution. I have tried the following, but it crashes Julia: using WebSockets, JSON uri = "wss://www.bitmex.com/realtime" json_part = "{'op': 'subscribe', 'args': ['orderBookL2_25:XBTUSD']}" inbox = Channel{String}(10)

问题 It seems that github uses a polling server for real time notifications (live.github.com) on its web interface. It seems like the technology is not Websocket based neither XHR-polling. How is it developed ? 回答1: It seems they use HTML5 Server-Sent Events. I found it after a while by looking at the request to live.github.com that accepts "text/event-stream" 来源： https://stackoverflow.com/questions/23367615/how-github-web-push-notifications-works

问题 I have a html5 page with var connection = new WebSocket('ws://foo.bar:8888'); But I get an error Mixed Content: The page at 'https://foo.bar/' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://foo.bar:8888/'. This request has been blocked; this endpoint must be available over WSS. I understand that, but I can't serve a Secure Websocket. Is there any way to make this work, except starting chrome with --allow-running-insecure-content or something like that

问题 I can't open a connection with Twitter Stream API. The only response I can get, no matter what I try, is 401 Unauthorized . I've made all kinds of tests, even using some libraries I've found on GitHub. Even outside my code, using cURL, I can't make it work. $oauth = array( 'oauth_consumer_key' => $this->m_oauth_consumer_key, 'oauth_nonce' => time(), 'oauth_signature_method' => 'HMAC-SHA1', 'oauth_token' => $this->m_oauth_token, 'oauth_timestamp' => time(), 'oauth_version' => '1.0' ); $base

问题 I am trying to get familiar with Django channels and web-sockets . I have a task - constantly streaming data to whoever connects to the channel. Currently, this is a piece of code from official tutorial with some improvements. class ChatConsumer(AsyncWebsocketConsumer): async def connect(self): self.room_name = self.scope['url_route']['kwargs']['room_name'] self.room_group_name = f'chat_{self.room_name}' if not hasattr(self, 'vehicle'): # this produses constant data stream self.vehicle =
