在流式传输PDF附件时如何强制“另存为"对话框 [英] How to force a Save As dialog when streaming a PDF attachment

问题描述

我正在使用以下代码将pdf流式传输到浏览器:

I am using the following code to stream a pdf to the browser:

header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header("Pragma: public");
header("Content-type:application/pdf");
header("Content-Disposition:attachment;filename=file.pdf");
echo $pdf;

工作正常，除了(无论如何在Chrome中)它只是保存文件"file.pdf"-它不会提示另存为"对话框，因此我可以重命名该文件(如果选择的话).

Works fine, except (in Chrome anyhow) it just saves the file "file.pdf" - it does not prompt a Save As dialog so I can rename the file, if I choose.

我怀疑这可能是与浏览器有关的事情之一，但是在传输要下载的pdf时是否可以用php标头强制使用另存为"对话框?

I suspect this may be one of those browser-dependent things, but is it possible to force a Save As dialog with the php headers when streaming a pdf for download?

(预先)感谢您的帮助

推荐答案

他们很可能具有在未选中(高级设置)的情况下要求在下载之前保存每个文件的位置.如果是这种情况，您将无能为力，因为这是他们的偏爱.

They most likely have Ask where to save each file before downloading unchecked (Advanced Settings). If this is the case, there's nothing you can do as this is their preference.
