一：實(shí)驗(yàn)名稱網(wǎng)絡(luò)聊天程序的設(shè)計(jì)與實(shí)現(xiàn)二：實(shí)驗(yàn)?zāi)康? 了解Socket通信的原理，并通過(guò)程序?qū)崿F(xiàn)通信的過(guò)程。三：實(shí)驗(yàn)要求熟悉Socket程序通信過(guò)程，熟悉在通信過(guò)程中流之間的轉(zhuǎn)換。程序中熟悉靈活運(yùn)用線程執(zhí)行相關(guān)操作。四：實(shí)驗(yàn)原理Socket通信的原理還是比較簡(jiǎn)單的，它大致分為以下幾個(gè)步驟。服務(wù)器端的步驟如下：建立服務(wù)器端的Socket，開(kāi)始偵聽(tīng)整個(gè)網(wǎng)絡(luò)中的連接請(qǐng)求。當(dāng)檢測(cè)到來(lái)自客戶端的連接請(qǐng)求時(shí)，向客戶端發(fā)送收到連接請(qǐng)求的信息，并建立與客戶端之間的連接。當(dāng)完成通信后，服務(wù)器關(guān)閉與客戶端的Socket連接?？蛻舳说牟襟E如下：建立客戶端的Socket，確定要連接的服務(wù)器的主機(jī)名和端口。發(fā)送連接請(qǐng)求到服務(wù)器，并等待服務(wù)器的回饋信息。連接成功后，與服務(wù)器進(jìn)行數(shù)據(jù)的交互。數(shù)據(jù)處理完畢后，關(guān)閉自身的Socket連接。
