1、了解.url文件内容

[DEFAULT]
BASEURL=

[InternetShortcut]
URL=
WorkingDirectory=
ShowCommand=
IconIndex=
IconFile=
Modified=
HotKey=

 

2、java实现

String rid = req.getParameter("rid");
	String idIndex = rid.substring(1,2);
	String contIndex = rid.substring(2,3);
	String roomId = rid.substring(2+Integer.valueOf(idIndex),2+Integer.valueOf(idIndex)+Integer.valueOf(contIndex));
	Map rinfo = vs.getRoomInfo(roomId);
	String shortInfo =  "[InternetShortcut]\n";
	shortInfo+="URL="+req.getScheme()+"://"+req.getServerName()+":"+req.getServerPort()+req.getContextPath()+"/servlet/VadioAction?ac=iroom&rid="+rid+"\n";
	shortInfo+="IconIndex=1\n IconFile=http://www.rainheng.com/"+rinfo.get("img")+" \n";
	shortInfo+=" IDList=[{000214A0-0000-0000-C000-000000000046}]\n Prop3=19,2";
	resp.setHeader("Content-type", "application/octet-stream");
	resp.setHeader("Content-Disposition", "attachment; filename="+URLEncoder.encode((String)rinfo.get("cname"),"UTF-8")+".url;");
	resp.getOutputStream().write(shortInfo.getBytes());

shortInfo的拼装内容为 构建.url内的内容

URLEncoder.encode((String)rinfo.get("cname"),"UTF-8") 解决中文乱码

IconIndex 和 IconFile指定了 图标
