FTP局域網(wǎng)與JAVA程序獲取網(wǎng)絡資源

FTP局域網(wǎng)與JAVA程序獲取網(wǎng)絡資源實驗內(nèi)容：.用Internet信息服務(IIS)管理器配置FTP,為FTP站點創(chuàng)建好登錄憑證，創(chuàng)建允許登錄的用戶，并用CMD窗口登陸并獲取ftp文件夾中的文件.兩臺電腦通過網(wǎng)線搭建局域網(wǎng).學習使用.URL獲取網(wǎng)絡資源實驗步驟:(用文字描述實驗過程，截圖說明)命令在DOS中的操作.啟用WIN10windows功能FTP和Web管理工具啟用成功后windows啟用成功后windows菜單新增IIS管理器.打開IIS管理器新建FTP站點文件舊密圖mth3文件舊密圖mth3.用微軟賬戶登錄并測試能否下載文件X丐Q-DELLOQD€lL，Q|~管里員:命令提示符ftp>open80連接到80o220MicrosoftFTPService200OPTSUTF8commandsuccessful-UTF8encodingnowON.用戶(80:(none)):852027972@331Passwordrequired密碼：230Userloggedin.ftp>dir200PORTcommandsuccessful.125Dataconnectionalreadyopen;Transferstarting.09-23-1607:52PM 1098011410441.xlsx226Transfercomplete.ftp:收到57字節(jié)，用時0.00秒57000.00千字節(jié)/秒。ftp>get11410441.xlsx200PORTcommandsuccessful.125Dataconnectionalreadyopen;Transferstarting.226Transfercomplete.ftp:收到10980字節(jié)，用時0.08秒138.99千字節(jié)/秒。ftp>bye221Goodbye.3:\WIND0WS\system32>4.使用.URL獲取網(wǎng)絡資源編寫Java程序如下并運行packagelab3;importjava.io.BufferedInputStream;importjava.io.FileOutputStream;importjava.io.IOException;import.HttpURLConnection;import.URL;publicclassURLDownload{publicstaticvoidmain(String[]args){try{System.out.println("begin");saveToFile("http:〃/upload/images/15EE/%E5%BC%A0%E8%BF%9B1.jpg","C://Users/Q/Documents/Q-SUSTC/ComputerNetwork/Lab3/ZhangJIN.jpg");System.out.println("end");}catch(Exceptione){e.printStackTrace();}}publicstaticvoidsaveToFile(StringdestUrl,StringfileName)throwsIOException{FileOutputStreamfos=null;BufferedInputStreambis=null;HttpURLConnectionhttpUrl=null;URLurl=null;byte[]buf=newbyte[1024];intsize=0;url=newURL(destUrl);httpUrl=(HttpURLConnection)url.openConnection();httpUrl.connect();bis=newBufferedInputStream(httpUrl.getInputStream());fos=newFileOutputStream(fileName);while((size=bis.read(buf))!=-1)fos.write(buf,0,size);fos.close();bis.close();httpUrl.disconnect();}}4.實驗結(jié)果：1.成功用微軟賬戶登陸FTP并下載文件~莒星三：命今捱示符 - □xopen10,20,113.180連摟到L80.22DMicrosoftFTPServ:ce200OPTSUTF8commandsuccessful-UTFSencodingnowOX.用戶(80;(none));852027972ftqq.con331Pa￡3WOTdrequired密碼：230Userloggedin.f-p>出r200PORIcomraandsuccessful.12.]Dataconnectionalreadvopen;Transfersmarting.09-23-IS07:52PM 1098011410441.x-sx225Transfercotiip_ete.ftp：收到57字節(jié),用時000秒3T000一W-丁字節(jié)/秒.f:p>11410441.eIsx200PORTcotiunandsuccessful.125Dataconnectionalreadyopen;Tranr-<?rs^artin?.225Transfercotnp_ete.ftp：收到109BD字節(jié)*用時。一08秒13199千字節(jié)/期口f-p>bye221Goodbye.C：\WmD0WS\systeni32>2.成功用Java程序下載張老師照片實驗問題回答才GaMS4■實驗問題回答才GaMS4■Al*a曬質(zhì)■ph：ggLbWdBM卻i皿a■F卜CKlHKnW4M嗎電廂7加i刎府9幅資jf1劉i鋼期在取a-sinn:*丁才＞E叫E3H鍬儂17的*-醐幅留1&$1litJ:lahSLaUl—l2.使用cmd窗口獲取同伴的共享文件并截圖。~會員:命令提示符ftp>open80連接到80o220MicrosoftFTPService200OPTSUTF8commandsuccessful-UTF8encodingnowON.用戶(80:(none)):852027972@331Passwordrequired密碼：230Userloggedin.ftp>dir200PORTcommandsuccessful.125Dataconnectionalreadyopen;Transferstarting.09-23-1607:52PM 1098011410441.xlsx226Transfercomplete.ftp:收到57字節(jié)，用時0.00秒57000.00千字節(jié)/秒。ftp>get11410441.xlsx200PORTcommandsuccessful.125Dataconnectionalreadyopen;Transferstarting.226Transfercomplete.ftp:收到10980字節(jié)，用時0.08秒138.99千字節(jié)/秒。ftp>bye221Goodbye
