[前端]关于使用ajax下载问题

iframe:

function download(){ var IFrameRequest=document.createElement("iframe"); IFrameRequest.id="IFrameRequest"; IFrameRequest.src="/test.zip"; IFrameRequest.style.display="none"; document.body.appendChild(IFrameRequest);}

后台:

public boolean download(String filePath, HttpServletResponse resp) { logger.debug("-------Start to download file[{}]----------", filePath); boolean isDownload = false; try { File file = new File(filePath); String fileName = file.getName(); InputStream in = new BufferedInputStream(new FileInputStream(file)); byte[] buffer = new byte[in.available()]; in.read(buffer); in.close(); resp.reset(); resp.setContentType("text/html"); resp.addHeader("Content-Disposition", "attachment;filename=" + new String(fileName.getBytes())); resp.addHeader("Content-Length", "" + file.length()); BufferedOutputStream toClient = new BufferedOutputStream(resp.getOutputStream()); toClient.write(buffer); toClient.flush(); toClient.close(); logger.debug("-------End to download file[{}]----------", filePath); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return isDownload; }
