我在Python中有以下腳本 . 它的作用是嘗試連接到MineCraft服務(wù)器，首先發(fā)送'handshake'，然后發(fā)送登錄請(qǐng)求 . 協(xié)議規(guī)格可以在這里找到：http://wiki.vg/Protocol

無(wú)論如何，python腳本工作正常，沒(méi)有錯(cuò)誤 . 但是，我相當(dāng)使用我編碼第二個(gè)數(shù)據(jù)包錯(cuò)誤，因?yàn)樗l(fā)送時(shí)，服務(wù)器控制臺(tái)上沒(méi)有任何內(nèi)容 . 播放器沒(méi)有連接或任何東西 . 由于“客戶端”沒(méi)有及時(shí)登錄，它最終會(huì)超時(shí)并關(guān)閉連接 .

基本上，無(wú)論如何誰(shuí)有struct.pack()的經(jīng)驗(yàn)應(yīng)該能夠在這里幫助我 . 我已經(jīng)評(píng)論了我不確定我是否已將所有內(nèi)容編碼正確的行 . 有關(guān)打包數(shù)據(jù)的詳細(xì)信息，請(qǐng)參見(jiàn)上面的鏈接 .

任何幫助將不勝感激，我對(duì)編碼/打包數(shù)據(jù)非常無(wú)能為力 . :(
