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

是否可以在 Django 视图中显示 PDF 文件，而不是让用户必须下载才能查看?

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，会怎么做?

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

这是我目前所拥有的 -

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

Django 有一个专门用于返回文件的类，文件响应.它流式传输文件，因此您不必在返回之前将整个文件读入内存.给你:

Django has a class specifically for returning files, FileResponse. It streams files, so that you don't have to read the entire file into memory before returning it. Here you go:

from django.http import FileResponse, Http404

def pdf_view(request):
    try:
        return FileResponse(open('foobar.pdf', 'rb'), content_type='application/pdf')
    except FileNotFoundError:
        raise Http404()

如果你有非常大的文件或者你经常这样做，更好的选择可能是使用正常的服务器配置在 Django 之外提供这些文件.

If you have really large files or if you're doing this a lot, a better option would probably be to serve these files outside of Django using normal server configuration.
