摘要：使用模擬請(qǐng)求打開運(yùn)行框，輸入后按回車鍵。回顯模式編輯模式接下來是考驗(yàn)手速的時(shí)候了，單身黨一定完勝的游戲。輸入按回車鍵，接著輸入連續(xù)按兩次回車鍵兩次回車代表提交請(qǐng)求輸入速度不夠快的話，將會(huì)連接失敗。

使用Telnet模擬Http請(qǐng)求

打開cmd運(yùn)行框，輸入Telnet www.baidu.com 80后按回車鍵。此時(shí)看到的界面是黑屏狀態(tài)，標(biāo)題欄顯示 Telnet www.baidu.com
如果提示telnet不是內(nèi)部或外部命令可以參考百度經(jīng)驗(yàn)。利用快捷鍵打開“Ctrl+]”打開Telnet回顯，按回車鍵后可以進(jìn)入編輯狀態(tài)。

回顯模式：

編輯模式：

接下來是考驗(yàn)手速的時(shí)候了，單身黨一定完勝的游戲。輸入GET /index.html HTTP/1.1按回車鍵，接著輸入HOST:www.baidu.com,連續(xù)按兩次回車鍵（兩次回車代表提交請(qǐng)求）輸入速度不夠快的話，將會(huì)連接失敗。可以將代碼寫入記事本，使用時(shí)直接復(fù)制就好了。

然后來看看服務(wù)器的返回?cái)?shù)據(jù)：
