IE8 问题：PDF 文件显示为内联

发布于 2024-10-05 12:33:31 字数 1038 浏览 0 评论 0原文

我正在从我的服务器下载 PDF。我将“内容处置”设置为“附件”。 Firefox 运行得非常好。但在 IE8 中它显示为内联。有解决此问题的快速指示吗？

编辑：

我正在使用 Springs 编写 PDF 字节数组流。并在客户端使用JSP来显示。

客户端：

我正在使用 dhtml 网格并保留标签。网格中的代码如下所示：

<a href='javascript:viewPDF(14)' target="_self" >View</a>

单击此按钮后，将调用 viewPDF 方法。我将此代码保存在我的 javascript 文件中。

function viewPDF(id) {
    $("#pdfID").val(id);
    $("#myform").attr('action',url);
    $("#myform").submit();
}

服务器端代码库：

ByteArrayOutputStream reportBAOS = getPDFByteArrayStream();/*This is my method which returns the byte array stream.*/
response.setContentType("application/pdf");
response.setHeader("Content-Disposition","attachment; filename=testfile");
response.setHeader("Pragma","Public");
response.setHeader("Cache-Control","must-revalidate,post-check=0,pre-check=0");
response.setHeader("Expires","0");
ServletOutputStream os = response.getOutputStream();
os.write(reportBAOS.toByteArray());
os.flush();
os.close();

I am downloading a PDF from my server. I set the "Content-Disposition" as "attachment". Its working very fine is Firefox. But in IE8 its displayed as inline. Any quick pointers to resolve this issue ?

Edit:

I am using Springs to write the PDF byte array stream. And using JSP in the client side to display.

Client side:

I am using a dhtml grid and keeping an tag. The code in the grid looks like:

<a href='javascript:viewPDF(14)' target="_self" >View</a>

On click of this the method viewPDF gets invoked. I kept this code in my javascript file.

function viewPDF(id) {
    $("#pdfID").val(id);
    $("#myform").attr('action',url);
    $("#myform").submit();
}

Server side code base:

ByteArrayOutputStream reportBAOS = getPDFByteArrayStream();/*This is my method which returns the byte array stream.*/
response.setContentType("application/pdf");
response.setHeader("Content-Disposition","attachment; filename=testfile");
response.setHeader("Pragma","Public");
response.setHeader("Cache-Control","must-revalidate,post-check=0,pre-check=0");
response.setHeader("Expires","0");
ServletOutputStream os = response.getOutputStream();
os.write(reportBAOS.toByteArray());
os.flush();
os.close();

添加这些标头：

header("Pragma: public"); //This one may work by itself.
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("200 HTTP/1.0 OK"); //HTTP 1.0 Compatible

这将强制 Internet Explorer 从服务器下载文件。

Add these headers:

header("Pragma: public"); //This one may work by itself.
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("200 HTTP/1.0 OK"); //HTTP 1.0 Compatible

This will force Internet Explorer to download the file from the server.

我花了一天时间才弄清楚问题出在哪里。但最后我明白了。

我不能说Evan Mulawski的回答是错误的。我什至尝试过他的代码。但没有帮助。最后发现文件扩展名丢失了。我刚刚将 .pdf 附加到测试文件中。

response.setHeader("Content-Disposition","attachment; filename=testfile.pdf");

现在我删除了以下内容。

response.setHeader("Pragma","Public");
response.setHeader("Cache-Control","must-revalidate,post-check=0,pre-check=0");
response.setHeader("Expires","0");

即使使用上面的代码，我仍然收到 PDF 作为附件。

I spent a day to figure out what was the issue. But finally I got it.

I cannot say the Evan Mulawski's answer wrong. I tried with his code even. But no help. Finally I found that the file name extension is missing. I just appended .pdf to testfile.

response.setHeader("Content-Disposition","attachment; filename=testfile.pdf");

Now I removed the following.

response.setHeader("Pragma","Public");
response.setHeader("Cache-Control","must-revalidate,post-check=0,pre-check=0");
response.setHeader("Expires","0");

Even with the above code still I am getting the PDF as an attachment.
