除了更改标题，如何强制保存为Firefox中的对话框？ [英] How to force save as dialog box in firefox besides changing headers?

问题描述

有没有办法在ff中为www.example.com/example.pdf强制另存为对话框？ （我不能改变头文件）如果你可以用base64输出文件到客户端，你可以使用数据uris来下载。
$ b $ $ $ $ $ $ $ $ $ $ $ location.href ='data：application / octet-stream; base64'+ appendPDFContentHere
或
< a href =data：application / octet-stream; base64，appendPDFContentHere> pdf< / a>

这只适用于非IE浏览器，但是如果您要求使用Firefox， 。

编辑：

下面的两个例子都包含了制作PNG的字节。如果您点击第一个，您可以像浏览器中一样查看图像。但是，如果您单击第二个链接，则会强制您下载图像。保存为.png，你会看到他们是完全相同的图像。这两个链接的唯一区别是mime类型 b
$ b

查看图片（预览缩短的网址） - mime type：image / png

下载图片（预览缩短网址） - MIME类型：应用程序/八位字节流

你问你用什么来代替 appendPDFContentHere ，答案是组成PDF的base64编码字节。我在线上使用 base64编码器进行编码在这个例子中使用的图像。

Is there a way to force a save as dialog box for www.example.com/example.pdf in ff? (i can't change the headers)

解决方案

If you can output the file to the client in base64, you could use data uris to for the download.

location.href = 'data:application/octet-stream;base64,' + appendPDFContentHere
OR
<a href="data:application/octet-stream;base64,appendPDFContentHere">pdf</a>

This will only work in non-IE browsers however but as you requested for firefox, this should work nicely.

EDIT:

Both of the examples below contain the bytes to make a PNG. If you click the first one you can view the image as you normally would in a browser. however, if you click the 2nd link, it will force you to download the image. Save it as a .png and you will see they are the exact same images. The only difference in the two links is the mime type

view image (preview shortened url) -- mime type: image/png

download image (preview shortened url) -- mime type: application/octet-stream

You asked what you put in place of appendPDFContentHere and the answer is the base64-encoded bytes that make up the PDF. I used this online base64 encoder to encode the image used in the example.
