這篇文章主要為大家詳細(xì)介紹了python實(shí)現(xiàn)簡單點(diǎn)對(duì)點(diǎn)p2p聊天，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

點(diǎn)對(duì)點(diǎn)聊天首先是基于多線程的網(wǎng)絡(luò)編程，其次就是將每一個(gè)連接都保存為一個(gè)具有獨(dú)一屬性的對(duì)象并添加到連接列表中，對(duì)于每一個(gè)連接對(duì)象發(fā)送過來的信息必須要包含主要的三項(xiàng)內(nèi)容（from,to,messages），這樣當(dāng)信息發(fā)送到服務(wù)器之后服務(wù)器根據(jù)to的連接對(duì)象遍歷連接列表找到目標(biāo)對(duì)象將信息發(fā)送給目標(biāo)，目標(biāo)拿到信息后就知道是誰發(fā)過來的，然后根據(jù)id號(hào)碼進(jìn)行回復(fù)。此實(shí)現(xiàn)將會(huì)繼續(xù)完善，后續(xù)新加功能將會(huì)在我個(gè)人github主頁展現(xiàn)
