使用nginx的Django sendfile无法将文件作为附件发送

Question

我正在使用django-sendfile将大文件作为附件发送到UI。这适用于sendfile.backends.simple后端但是当我使用sendfile.backends.nginx时，它会在nginx日志上返回404错误。

我认为我的nginx配置有问题。

views.py

class FileDownloadView(View):
    def get(self, request, id_file):
        obj = FileCombined.objects.get(id_file=id_file)
        return sendfile(request, obj.path, attachment=True)

urls.py

from django.conf.urls import url
from django.urls import path

urlpatterns += [
    path(r'file/id/<str:id_file>/delete/', FileDeleteView.as_view(), name='files-delete'),
    path(r'file/id/<str:id_file>/download/', FileDownloadView.as_view(), name='files-download'),
    ]

settings.py

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
SENDFILE_BACKEND = "sendfile.backends.nginx"
SENDFILE_ROOT = os.path.join(BASE_DIR, 'media')
SENDFILE_URL = '/media'

/etc/nignx/sites-enabled/myapp

server { # simple reverse-proxy
    listen       80;
    server_name  localhost;
    sendfile            on;

    # serve static files
    location /static {
       proxy_pass      http://127.0.0.1:8000/static;
    }

    location /media/ {
        internal;
        root  /home/foo/project/django-combine/media;
    }

    location / {
      proxy_pass      http://127.0.0.1:8000;
    }
}

nginx/access.log

127.0.0.1 - - [30/Dec/2017:08:20:01 +0530] "GET /file/id/5114a7721b6943fb31fc143a20adbec630bb5eb2516d7574b881454209338eed/download/ HTTP/1.1" 404 208 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/52.0.2743.116 Chrome/52.0.2743.116 Safari/537.36"

实际上我要下载的文件存在于/home/foo/project/django-combine/media目录中。

print(obj.path)存在于我的视图中

/home/foo/project/django-combine/media/google-oauth2|817468732648743/33601a74-de02-4b83-8587-1f8c3d8c96fb/output/combined.csv

你需要改变

root /home/foo/project/django-combine/media/;

至

root /home/foo/project/django-combine/; 

因为根中的/media是root /home/foo/project/django-combine/media/media的有效途径。

你甚至可以使用alias /home/foo/project/django-combine/media/;而不是root /home/foo/project/django-combine/media/。那也行得通。对于别名，不会附加位置路径

此外，你需要确保你没有像|这样的特殊符号，这使得nginx很难找到文件
