PermissionError :/下载/

Question

当我尝试下载该文件时，文件上写着PermissionError在/ download /

views.py

def download(request, path):
   file_path = os.path.join(settings.MEDIA_ROOT, path)
   if os.path.exists(file_path):
        with open(file_path, 'rb') as f:
        response = HttpResponse(f.read(), content_type="application/vnd.ms-excel")
        response['Content-Disposition'] = 'inline; filename=' + os.path.basename(file_path)
        return response
   raise Http404

urls.py

re_path(r'^download/(?P<path>.*)$', views.download)

html模板中的

<a href="/download">Download</a>

我已经尝试了所有东西，比如将项目文件夹移动到另一个目录，或者以admin等方式运行它，但是它说

    Internal Server Error: /download/
Traceback (most recent call last):
  File "C:\Users\Zako5\.virtualenvs\jurnal-6LxuXEYu\lib\site-packages\django\core\handlers\exception.py", line 34, in inner
    response = get_response(request)
  File "C:\Users\Zako5\.virtualenvs\jurnal-6LxuXEYu\lib\site-packages\django\core\handlers\base.py", line 126, in _get_response
    response = self.process_exception_by_middleware(e, request)
  File "C:\Users\Zako5\.virtualenvs\jurnal-6LxuXEYu\lib\site-packages\django\core\handlers\base.py", line 124, in _get_response
    response = wrapped_callback(request, *callback_args, **callback_kwargs)
  File "C:\Users\Zako5\PycharmProjects\jurnal\jurnal_app\views.py", line 40, in download
    with open(file_path, 'rb') as fh:

[27/Mar/2019 10:56:09] "GET /download/ HTTP/1.1" 500 66483

如果能提供任何帮助，我将不胜感激)这个问题已经激怒我一个星期了。

Answer 1

路径是空的，因此它试图打开MEDIA_ROOT，这是一个目录。

假设您的目录结构如下：

-media root
  - 1.xlsx

然后，您将旅游html更新为

<a href="/download/1.xlsx">Download</a>

因此，路径变量变为1.xlsx。
