使用Pyramid，ningx，X-Accel-Redirect标头提供pdf下载 [英] Serve up pdf as a download with Pyramid, ningx, X-Accel-Redirect Header

问题描述

我希望用户能够单击这样的链接:

I want a user to be able to click a link like this:

<a href="/download?file=123">download</a>

拥有一个金字塔1.2.7应用程序来处理这样的视图

Have a Pyramid 1.2.7 app handle the view like this

@view_config(route_name='download')
def download(request):
    file_id = request.GET['file']
    filename = get_filename(file_id)
    headers = request.response.headers
    headers['Content-Description'] = 'File Transfer'
    headers['Content-Type'] = 'application/force-download'
    headers['Accept-Ranges'] = 'bytes'
    headers['X-Accel-Redirect'] = ("/path/" + filename + ".pdf")
    return request.response

我的nginx配置看起来像这样

And my nginx configuration looks like this

location /path/ {
 internal;
 root /opt/tmp; 
}

这一切正常，但是浏览器显示了一堆PDF垃圾，而不是显示pdf的浏览器已下载.

This all works but instead of the browser showing a pdf has download, the browser displays a bunch of PDF garbage.

如何设置金字塔视图以使浏览器执行正确的操作?

How do I setup my Pyramid view to get the browser to do the right thing?

推荐答案

如果要指示Web浏览器应该下载资源而不是显示资源，请尝试使用Content-Disposition标头

If you want to indicate that a web browser should download a resource rather than display it, try using the Content-Disposition header as described in RFC 6266. For example, the following response header will tell the browser to download the file:

Content-Disposition: attachment

您还可以通过此标头为下载的文件指定文件名(如果它与URL中的最后一个路径部分不同):

You can also specify a file name for the downloaded file through this header (if it differs from the last path component in the URL):

Content-Disposition: attachment; filename=foo.pdf

查看 Nginx文档，此响应标头应与X-Accel-Redirect功能一起正常使用您正在使用.

Looking at the Nginx documentation, this response header should work correctly in conjunction with the X-Accel-Redirect feature you're using.
