怎么从网站上下载txt

挺好用的。

原文：

Jsp代码

<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<HTML>
<HEAD>
</HEAD>
<BODY>
<a href = "download1.jsp?filepath=d://&filename=1a.txt" >downloadtest1</a>
</BODY>
</HTML>


<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<HTML>
<HEAD>
 
</HEAD>
 
<BODY>
<a href = "download1.jsp?filepath=d://&filename=1a.txt" >downloadtest1</a>
 
</BODY>
</HTML>

这是页面上的连接，我传了个路径和文件名

Java代码

<%
String filename = request.getParameter("filename");//"1a.txt";
String filepath = request.getParameter("filepath");//"d://";
int i = 0;
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename = "+filename);
java.io.FileInputStream fileInputStream = new java.io.FileInputStream(filepath+filename);
while((i= fileInputStream.read()) != -1){
out.write(i);
}
%>


<% 
	String filename = request.getParameter("filename");//"1a.txt"; 
	String filepath = request.getParameter("filepath");//"d://";
	 int i = 0;
	response.setContentType("application/octet-stream");
	response.setHeader("Content-Disposition","attachment;filename = "+filename); 
	java.io.FileInputStream fileInputStream = new java.io.FileInputStream(filepath+filename);
	while((i= fileInputStream.read()) != -1){
		out.write(i);
	}
%>

这是被调用的download1.jsp，这个jsp就是执行直接下载文件的不管是txt还是word文档都可以直接下载
