如何强制文件在浏览器中打开而不是下载（PDF）？ [英] How do I force files to open in the browser instead of downloading (PDF)?

问题描述

当取消选中在浏览器中显示PDF选项时，是否有办法强制PDF文件在浏览器中打开？

Is there a way to force PDF files to open in the browser when the option "Display PDF in browser" is unchecked?

我尝试使用embed标签和iframe，但只有在选中该选项时才有效。

I tried using the embed tag and an iframe, but it only works when that option is checked.

我该怎么办？

推荐答案

要向浏览器表明应该在浏览器中查看该文件：

To indicate to the browser that the file should be viewed in the browser:

Content-Type: application/pdf
Content-Disposition: inline; filename="filename.pdf"

要下载文件而不是查看文件：

To have the file downloaded rather than viewed:

Content-Type: application/pdf
Content-Disposition: attachment; filename="filename.pdf"

如果文件名包含特殊字符，则需要文件名周围的引号as filename [1] .pdf 这可能会破坏浏览器处理响应的能力。

The quotes around the filename are required if the filename contains special characters such as filename[1].pdf which may otherwise break the browser's ability to handle the response.
