Question

我已经编写了通过http请求下载pdf文件的代码。

 public void downloadDocument(HttpServletRequest request,
            HttpServletResponse response, @PathVariable("id") String docId)
            throws Exception {
        HttpSession session = request.getSession(true);
        int accountId = (Integer) session.getAttribute("ownerAccountId");
        Map<String, String> docMap = DbInteractor.getUploadedDocsByDocId(
                Integer.valueOf(docId), accountId);
        String docName = docMap.get("name");
        String typeName = docMap.get("type");
        String[] fileName = docName.split("\\.(?=[^\\.]+$)");
               typeName= typeName.replace(" ", "");
        if (typeName.equals("CCD/CCR")) {
            typeName = "CCDorCCR";
        }
        String filename = typeName + docId + "." + fileName[1];
        System.out.println(filename);
        FileInputStream fileInputStream = new FileInputStream(
                Constants.DOCUMENTS_PATH + filename);
        response.setHeader("Expires", "0");
        response.setHeader("Cache-Control",
                "must-revalidate, post-check=0, pre-check=0");
        response.setHeader("Content-disposition", "attachment; filename="
                + docName);
        OutputStream os = response.getOutputStream();
        IOUtils.copy(fileInputStream, os);
        os.flush();
        os.close();
    }

但是这个文件会自动下载到chrome。有没有办法强制chrome在查看器中打开这个文档（或者要求在chrome中打开对话框）

Answer 1

您通过发送“Content-Disposition：attachment”强制浏览器下载。

强制chrome在查看器中打开下载的pdf
