从服务器上下载txt文件后，txt文件比源文件多了html的内容。
程序如下：
FileInputStream fis = new FileInputStream(new File( "c:\\test.txt "));
//response.setContentType( "applicaton/x-filter ");
response.setHeader( "Content-Disposition ", "attachment;filename=test.txt " );
response.setHeader( "Content-Length ", String
.valueOf(fis.available()));
ServletOutputStream sos = response.getOutputStream();
byte[] buffer = new byte[1024];
int location = 0;
while ((location = fis.read(buffer)) != -1) {
sos.write(buffer, 0,location);
}
fis.close();
sos.flush();
sos.close();
c:\\text.txt文件内容为abc,但下载到本地上文件的内容如下：
abc
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN ">
<HTML>
<HEAD>
<META http-equiv= "Content-Type " content= "text/html; charset=UTF-8 ">
<META name= "GENERATOR " content= "IBM Software Development Platform ">
<META http-equiv= "Content-Style-Type " content= "text/css ">
<LINK href= "../theme/Master.css " rel= "stylesheet " type= "text/css ">
<TITLE> Download.jsp </TITLE>
<LINK rel= "stylesheet " type= "text/css " href= "../theme/stylesheet.css "
title= "Style ">
</HEAD> <BODY> </BODY> </HTML>
请问各位高手，如何解决？如何去掉自动添加的html的部分？

顶一下，学习，
------解决方案--------------------
ServletOutputStream sos = response.getOutputStream();
sos.clear()或者什么的
清空一下buffer
------解决方案--------------------
response.setContentType(”APPLICATION/OCTET-STREAM”);
------解决方案--------------------
简单 明了 <a href
------解决方案--------------------
ServletOutputStream sos = response.getOutputStream();
servlet中的当然会是标准的html了
直接用输出流就好了

楼上的都说明了。我只能帮顶。

是在jsp中还是servlet里面写的？

<%@ page contentType= "text/html; charset=gb2312 " %> <%@ page import= "java.io.* " %> <%
String fileName = "kkk.txt ";
InputStream inStream=new FileInputStream( "E:/liaohaiying/cp/kk.txt ");
response.reset();
response.setContentType( "bin ");
response.addHeader( "Content-Disposition ", "attachment; filename= " + fileName);
byte[] b = new byte[100];
int len;
while((len=inStream.read(b)) > 0)
response.getOutputStream().write(b,0,len);
inStream.close();
