While SSE and HTTP/2 Server Push both enable real-time, push-based communication between a server and a client, they work in different ways and have different use cases. SSE is best suited for applications that need to send a small number of real-time events from the server to the client...
A server-sent event sent viastream.sendEvent()or returned fromfetch()has to have the following shape: interfaceServerSentEvent{data:string|string[]event?:string,id?:stringretry?:number} Besidesstream.sendEvent(event: ServerSentEvent)there is alsostream.sendComment(comment: string)andstream.close()...
另外大多数浏览器实现了SSE(Server-Sent Events,服务器发送事件) API,SSE支持短轮询、长轮询和HTTP流,使用方式如下: 客户端: var source = new EventSource("test.php"); //生成EventSource对象,url必须同源 var len = 0; source.onopen = function(){ //如果连接断开,还会自动重新连接 console.log("connec...
ws.send('Hello Server!'); } 如果要指定多个回调函数,可以使用addEventListener方法。 ws.addEventListener('open', function (event) { ws.send('Hello Server!'); }); webSocket.onclose 实例对象的 onclose 属性,用于指定连接关闭后的回调函数。 ws.onclose = function(event) { var code = event.code;...
比如golang中http server处理：在浏览器上请求运行结果如下所示：相对来说，在c/c++语言中没有默认的http模块支持，需要依赖第三方开源库来实现http服务器功能。libevent中提供了相关http模块，并且也支持路由处理。本文介绍基于libevent实现c/c++语言版本的http server。定义HttpServer类，该类的功能包括初始化创建http...
此可选extesion使用https://html.spec.whatwg.org/multipage/server-sent-events.html#server-sent-events中指定的支持服务器到客户端通信的WHATWG服务器发送事件协议。当WHEP资源支持时,必须在初始HTTP“201 Created”响应中返回具有“urn:ietf:params:whep:ext:sse”的“rel”属性的“Link”头字段,并带有服务器发...
