server-sent-events

问题 I'm learning & doing SSE for the first time in rails! My controller code: def update response.headers['Content-Type'] = 'text/event-stream' sse = SSE.new(response.stream, event: 'notice') begin User.listen_to_creation do |user_id| sse.write({id: user_id}) end rescue ClientDisconnected ensure sse.close end end Front end: var source = new EventSource('/site_update'); source.addEventListener('notice', function(event) { var data = JSON.parse(event.data) console.log(data) }); Model pub/sub class

问题 Maybe this is a problem in Flask, there is no way to handle disconnection event on the server side. In Response class, there is a method named "call_on_close", where we can add a function without argument, e.g. on_close(), it will be fired when the response object's close method called, but this doesn't happen when I call EventSource.close() from the client side in Javascript. code on server side: from flask import Response r = Response(stream(), ...) r.call_on_close(on_close) return r def on

问题 I have implemented a server sent events with eventsource on my web application. Basically in javascript my code look like : var myEventSource; if (typeof(EventSource) !== "undefined" && !myJsIssetFunction(viridem.serverSideEvent.config.reindexProcessingEvent)) { myEventSource = new EventSource('/my/url/path.php?event=myevent'); EventSource.onmessage = function(e) { [...] //Dealing with e.data that i received ... } } on the PHP side I have something Like this : <?php header('Content-Type: text

问题 For a project, I need to implement SSE (Server Sent Events) in a C# Application. Although this may sound easy, I've got no clue how to solve this. As I'm new to C# (though, not new to programming in general) I took an excursion to Google and tried to look for some sample code. From what I've seen so far, I could learn to build a HTTP Server with C# or consume server sent events. But I found nothing about sending SSEs. What I'm trying to get my head around: how can I keep sending updated data

问题 I've been trying to get a webapp to work which uses Server-Sent Events. The app that I've written works on my local machine when using Flask's app.run() method. But when I run it on GAE, I've not been able to make it work. The webapp uses SSE to publish a message with the current time every so often. The client simply adds it to the HTML of a div. Flask app import random from datetime import datetime from flask import render_template, Response from time import sleep from message_server import

问题 Our server is used to Nginx as webserver and add compile module of nginx_push_stream. Before used to push stream had used to Restfull then changed to Websocket but websocket sometimes loss when the client or server had small bandwith. At 2019 year, from Websocekt to Server Sent Event (SSE) / event-source such as event stream or text/event-stream to reduce loss both of client or server. Please anyone have any idea for library event stream is able to use to android client and iPhone client. I
