小程序web服务器是什么,网站web服务器分析小程序

1.目前WEB主流服务器：Apache 、Microsoft IIS和其他

2.Java程序:

类：SocketTest.java

import java.net.*;

import java.io.*;

import java.text.*;

public class SocketTest

{

public static int[] num={0,0,0};

public static void main(String[] args)

{

try{

BufferedReader is=new BufferedReader(new FileReader("serverlist.txt"));

String server;

String format = "%1$-25s%2$-48s";

System.out.format(format,"网址","服务器信息");

System.out.println("===========================================================");

while ((server = is.readLine()) != null) {

ShowServerInfo(server.trim(),80);

}

System.out.println("===========================================================");

System.out.println("Apache:"+num[0]+",比例 "+NumberFormat.getPercentInstance().format(num[0]*1.0/(num[0]+num[1]+num[2])));

System.out.println("IIS:"+num[1]+",比例 "+NumberFormat.getPercentInstance().format(num[1]*1.0/(num[0]+num[1]+num[2])));

System.out.println("Other:"+num[2]+",比例 "+NumberFormat.getPercentInstance().format(num[2]*1.0/(num[0]+num[1]+num[2])));

is.close();

}catch(Exception ex){

ex.printStackTrace();

}

}

public static void ShowServerInfo(String server,int port){

try{

Socket sc=new Socket(server,port);

StringBuffer sb=new StringBuffer();

sb.append("HEAD / HTTP/1.1\n");

sb.append("Accept: */* \n");

sb.append("Host: "+server+"\n");

sb.append("Connection: Keep-Alive \n\n");

sc.getOutputStream().write(sb.toString().getBytes());

BufferedReader in=new BufferedReader(new InputStreamReader(sc.getInputStream()));

String userInput;

String format = "%1$-25s%2$-54s\n";

while ((userInput = in.readLine()) != null) {

if(userInput.startsWith("Server:")){

if(userInput.length()>55) userInput=userInput.substring(0,54);

if(userInput.toUpperCase().indexOf("APACHE")>=0) num[0]+=1;

else if(userInput.indexOf("IIS")>0) num[1]+=1;

else num[2]+=1;

break;

}

}

sc.getOutputStream().close();

in.close();

sc.close();

}catch(Exception ex){

System.out.println("Err:"+server+","+ex.getMessage());

}

}

}

3.所需文本：serverlist.txt

4.结果显示：
