如何在Django视图中显示PDF文件 [英] How to show a PDF file in a Django view

问题描述

可以在Django视图的中显示一个PDF文件，而不是让用户下载它看看吗？

Is it possible to show a PDF file in the Django view, rather than making the user have to download it to see it?

如果可能的话，该怎么办？

And if it is possible, how would it be done?

这是我到目前为止 -

This is what I have so far -

@login_required
def resume(request, applicant_id):

  #Get the applicant's resume
  resume = File.objects.get(applicant=applicant_id)
  fsock = open(resume.location, 'r')
  response = HttpResponse(fsock, mimetype='application/pdf')

  return response

推荐答案

简单来说，如果你有一个PDF文件，你想输出通过Django视图，您需要做的是将文件内容转储到响应中并使用适当的mimetype发送。

Simplistically, if you have a PDF file and you want to output it through a Django view, all you need to do is dump the file contents into the response and send it with the appropriate mimetype.

def pdf_view(request):
    with open('/path/to/my/file.pdf', 'r') as pdf:
        response = HttpResponse(pdf.read(), mimetype='application/pdf')
        response['Content-Disposition'] = 'inline;filename=some_file.pdf'
        return response
    pdf.closed

您可以直接返回响应而不指定Content-Disposition，但更好地表示您的意图，并且还允许您指定文件名，以防万一用户决定保存它。

You can probably just return the response directly without specifying Content-Disposition, but that better indicates your intention and also allows you specify the filename just in case the user decides to save it.

另外，请注意，上面的视图不会处理由于某种原因无法打开或读取文件的场景。由于它使用与完成，它不会引发任何异常，但您仍然必须返回某种响应。不过，您可以简单地提出一个 Http404 或

Also, note that the view above doesn't handle the scenario where the file cannot be opened or read for whatever reason. Since it's done with with, it won't raise any exceptions, but you still must return some sort of response. You could simply raise an Http404 or something, though.
