servlet_response下载文件
通过response响应头content-disposition,来下载文件,如果文件有中文,就用url编码
1 String path = this.getServletContext().getRealPath("/download/妞儿.jpg"); 2 String fileName = path.substring(path.lastIndexOf("\\") + 1); 3 //如果fileName是中文名字,那么我就要用URL编码 URLEncoder.encode(s, enc); 4 response.setHeader("content-disposition", "attachment;filename=" + URLEncoder.encode(fileName,"UTF-8")); 5 InputStream in = new FileInputStream(path); 6 OutputStream out = response.getOutputStream(); 7 int len; 8 byte[] buffer = new byte[1024]; 9 while((len = in.read(buffer)) > 0){ 10 out.write(buffer,0,len); 11 } 12 in.close();
