資源簡(jiǎn)介
前段時(shí)間在做WCF開(kāi)發(fā)的過(guò)程中，用戶需要在服務(wù)端對(duì)客戶端進(jìn)行監(jiān)控，需要知道客戶端什么時(shí)候上線，什么時(shí)候下線，當(dāng)然服務(wù)端也可以給客戶端推送信息，就是所謂的雙向通信了。 要雙向通信用我以前的HTTP協(xié)議是行不通了，問(wèn)了一下別人，別人說(shuō)了一個(gè)“心跳更新”這個(gè)概念，想必大家都懂這個(gè)吧，大概意思呢就是A向B定時(shí)發(fā)送一個(gè)消息來(lái)監(jiān)測(cè)B是否活著，如果活著就返回一個(gè)消息，死掉當(dāng)然就不需要了，其實(shí)我覺(jué)得心跳更新就是TCP協(xié)議，也就是雙向通信，互相監(jiān)測(cè)活著或者死掉。
