模拟在浏览器中添加自定义HTTP头信息

1、服务器端添加HTTP响应头信息

     在服务器端添加HTTP响应头信息通常很容易，比如在jsp中，直接通过response.addHeader(String key, String value)或者response.setHeader(String key, String value)方法添加, 像这样：

      response.setHeader("WasuStbId", "1234567890");

      response.addHeader("WasuUserNo", "1234567890-0987654321");

 

在linux环境下可以通过curl命令来验证，如：curl -I http://xxxx.xxxx.xxxx/xxx.jsp得到的结果为

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Set-Cookie: JSESSIONID=B8F444E7C38BC5C6A4B6EC29780927F0; Path=/mailproxy
Last-Modified: Tue, 10 Feb 2009 02:12:11 GMT
Expires: Tue, 10 Feb 2009 02:12:21 GMT
WasuStbId: 1234567890
WasuUserNo: 1234567890-0987654321
Cache-Control: public
Pragma: Pragma
Content-Type: text/html
Content-Length: 5414

2、在客户端添加HTTP自定义头信息

     两种方式模拟在HTTP请求中添加自定义HTTP头信息。

    a、先给出服务器端请求的jsp页面代码,用于展示上传的HTTP头信息;

<!--
获取HTTP请求头信息,打印出来.
-->

<%
  String userAgent =  request.getHeader("User-Agent");
  String ext =  request.getHeader("Ext");
  String wasuStbId =  request.getHeader("WasuStbId");
%>

10.0.85.125 --> a<br/>
User-Agent:<%=userAgent%><br/>
Ext:<%=ext%><br/>
WasuStbId:<%=wasuStbId%><br/>

 

    b、java方式

 

		try {
			URL url = new URL("http://10.0.86.233/jsptag.jsp");
			URLConnection urlConn = url.openConnection();
			
			urlConn.setDoOutput( true );  
			urlConn.setRequestProperty( "Accept", "*/*" );  
			urlConn.setRequestProperty( "Accept-Language", "java" );  
			urlConn.setRequestProperty( "Content-Type", "multipart/form-data" );  
			urlConn.setRequestProperty( "Accept-Encoding", "gzip, deflate" );  
			urlConn.setRequestProperty( "User-Agent", "wawawawawa" );
			urlConn.setRequestProperty( "Ext", "Ext12345;Ext09876;Ext13579;Ext08642" );
			urlConn.setRequestProperty( "WasuStbId", "1234567890;0987654321;1357908642" );
			urlConn.setRequestProperty( "Connection", "Keep-Alive" );
			urlConn.setRequestProperty( "Cache-Control", "no-cache" );  
			
			InputStream is = urlConn.getInputStream(); 
			BufferedInputStream bis = new BufferedInputStream(is);    
			ByteArrayOutputStream baos = new ByteArrayOutputStream();  
			int i = 0;  
			while((i = bis.read()) != -1){  
			      baos.write(i);  
			}  
			System.out.println(baos.toString());  
			bis.close();  
			is.close(); 
		} catch (Exception e) {
			e.printStackTrace();
		}

    需要引入的类:

import java.io.BufferedInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import java.net.URL;
import java.net.URLConnection;

 

    c、直接socket方式

    直接在command模式下，比如在xp的cmd下面敲入下面代码：

 

c:\>telnet 10.0.86.233 80        #注意,是ip地址+空格+端口号
GET /jsptag.jsp HTTP/1.1          #GET全大写,空格+地址页面+空格+HTTP/1.1
Host: 10.0.86.233:80               #"Host:"+空格+"ip地址：端口号"
Wasu-Stb-Id: 1234567890       #自定义头信息,"key+空格+value".
Ext: 12345;67890                     #自定义头信息,"key+空格+value".
回车

#下面为得到的信息
HTTP/1.1 200 OK
Server: nginx/0.7.33
Date: Tue, 10 Feb 2009 02:15:25 GMT
Content-Type: text/html;charset=ISO

Set-Cookie: JSESSIONID=EFEF64D30F29
Content-Length: 115

10.0.85.125 --> c<br/>
User-Agent:wawawawa<br/>
Ext:Ext12345;Ext09876;Ext13579;Ext08642<br/>
WasuStbId:1234567890;0987654321;1357908642<br/>
Connection closed by foreign host.
