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()...
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服务，添加路由处理函数，添加默认路由静态资源处理，以及启动运行htt...
