一段Server Push的調試

現在能搜尋到的99年最早的在國內介紹Server Push的文章就是自己那篇"Server Push具體實現",今天調試竟然花了很長時間

才正常工作。放在這裡做記錄吧：

 

package test;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Test extends HttpServlet{
 public void service(HttpServletRequest request,HttpServletResponse response)
  throws IOException
 {
  ServletOutputStream out = response.getOutputStream();
  String strBoundary = "myRandomString";
  response.setContentType("multipart/x-mixed-replace;boundary=" + strBoundary);
  
  out.print("--"+strBoundary+"/r/n");
  out.print("Content-type: image/jpeg/r/n/r/n");
  File f = new File("d:/96.jpg");
  byte[] buf = new byte[(int)f.length()];
  FileInputStream in = new FileInputStream(f);
  in.read(buf);
  in.close();
  out.write(buf);
  out.flush();

   try{
    Thread.sleep(2000);
   }catch(Exception e){}
  for(int i = 0; i < 10; i++){
   out.print("--"+strBoundary+"/r/n");
   out.print("Content-type: text/html/r/n/r/n");
   out.print("<script>alert(1)</script>/r/n/r/n");
   out.flush();
   try{
    Thread.sleep(1000);
   }catch(Exception e){}
  }
  out.print("--"+strBoundary+"--/r/n");
 }
}
