server-sent-events

问题 I implemented server-sent events to receive messages from the server. I describe how I implemented it on another question Now I am trying to run it inside a shared worker to prevent the user from opening multiple connections to the servers via multiple browser tabs. Here is what I have done to run the code inside a Shared Worker created a file calles worker.js and I put this code inside of it self.addEventListener('getMessagingQueue', function (event) { console.log('Listener is Available');

问题 I'm new to Server-Sent-Events . I have an event emitter which sends updates in every 2 seconds(using SseEmitter , hosted on Tomcat) I see that the messages are not being sent to the previous windows when I open the URL in a new window. Please see the image below. Is it's an expected behavior of Server-Sent-Events? I nee to send updates to all the clients that are connected to my streaming URL. Do I need any additional configurations or settings on my application or the tomcat server? Please

问题 Tomee-8 is not released yet. TomEE-7 does not support "server sent events" out of the box. Is there a way to make TomEE-7 cope with SSE? 来源： https://stackoverflow.com/questions/55239121/server-sent-events-with-tomee-7

问题 I have a server that needs to receive real time updates from Firebase, for multiple users, where each user grants Oauth access to his Firebase data to my app. My server is implemented using Firebase REST Streaming, based on Server Sent Events. I need to know if there is a way to multiplex Firebase data pertaining to multiple users on a single stream. I would like to be able to set up the stream with Oauth tokens pertaining to multiple users, and to subsequently receive real time updates

问题 I'm setting up a master-detail interface with two routes. The parent route houses an EventSource stream that regularly updates it's model. I'm trying to make it so when the parent route's model suffers a change on any of its items, if the current detail view is displaying any of the changed items then it should be updated. I'm currently trying to make a binding on the receptor route to receptores 's controller's model and observing that: Edited per blessenm's suggestions: var App = Ember

问题 Can anyone guide me as how server sent events works in servicestack framework. I want to get response to load asynchronously. If a response contains a list of items, I want the list of items to populate while the service is processing the list. Suppose, I have a response object, company which contains list of permanent employee and list of contractual employee which comes from two different sources. I want the response object to populate the list of employees which is processed first. I don't

问题 I am implementing Server-Sent Events in my PHP Codeigniter application. I have a long running script and SSE shows progress bar for the user. This bit works great. The missing piece: how do I display my HTML content when all the data is ready? PHP: public function LongRunningScript() { header("Content-Type: text/event-stream"); header("Cache-Control: no-cache"); header("Connection: keep-alive"); function send_message($id, $progress) { $d = array('message' => "", 'progress' => $progress); echo

问题 I am playing around with spring webflux. I have created a project which would listen on a mongo capped collection and return the flux of data as and when it comes. I am using @Tailable in my repository method. My controller looks like this @GetMapping("/findall") public Flux<Product>> findAll() { return productRepository.findAllProducts().; } This is working perfectly fine. I tested this by addind a doOnNext(...) , Whenever there is a new item added to my capped collection, consumer inside

问题 I am reading a SSE by using this method Public Shared Sub ReadStreamForever(ByVal stream As Stream) Dim encoder = New UTF8Encoding() Dim buffer = New Byte(2047) {} Dim counter As Integer = 0 While True If stream.CanRead Then Dim len As Integer = stream.Read(buffer, 0, 2048) counter = counter + 1 If len > 0 Then Dim text = encoder.GetString(buffer, 0, len) SSEApplication.Push(text) 'Here I collect the text slices to a List(of string) object Else Exit While End If Else Exit While End If End

问题 When I use signalR which falls back to ServerSentEvents, and I can see on fiddler an open connection to the server waiting for chunked data, does it mean a thread is being occupied on the server at this time? If so, it is not quite efficient as far as I see it.. For example I would not write such code in the server that blocks a thread: public ActionResult ServerSentEvents { DateTime currentdate = DateTime.Now; Response.ContentType = "text/event-stream"; while (currentdate.AddMinutes(1) >
