【问题描述】：
访问帖子页面时出现奇怪的错误。我制作 Web 应用程序，您可以在其中发布图像和视频。使用图像它可以正常工作，但是当我发布视频并转到其页面时，服务器会给我以下输出：

图像和视频的代码是相同的，这就是我不明白这一点的原因。 这是我的视图功能，当您访问帖子页面时使用：
def post_info(request, pk):
form = CommentForm(request.POST or None)
post = get_object_or_404(Post, pk=pk)
same_author_posts = Post.objects.filter(author=post.author)
if request.method == 'POST':
if form.is_valid():
instance = form.save(commit=False)
instance.author = request.user
instance.post = post
instance.save()
form = CommentForm()
messages.success(request, 'Comment is approved!')
return HttpResponseRedirect('/post/%s/'%(pk))
else:
messages.error(request, 'Comment is not valid!')
return HttpResponseRedirect('/post/%s/'%(pk))
context = {
'form': form,
'post': post,
'same_author_posts': same_author_posts,
}
return render(request, 'post/post_info.html', context)
可能它在响应中有一些带有状态码的东西，但是为什么它在加载图像时不显示它以及如何修复它？
【问题讨论】：
-
您是否检查了您存储文件的目录的权限？
-
是的，一切正常。我注意到，当例如 127.0.0.1:8000 更改为 127.0.0.1:9000 时，有时会引发相同的错误。但是我还是能理解为什么我去post_info.html看图片时他没有显示，只有视频输出错误。
-
你发现了什么？ ): 我有同样的错误
-
我正在做一些学校项目。我发现当文件太大时会发生该错误。我不知道这是为什么。例如，我制作网站，您可以在其中发布图像或视频以及更多内容。问题是浏览器渲染视频或大图像时，所以我压缩视频并且它工作正常。但是当我在笔记本电脑上运行相同的视频（比我的 PC 慢）时，它会显示相同的错误。所以，我认为这是 Django 开发服务器的一些错误（在我的情况下）。该错误不会停止网站或其他任何内容，它仍然可以正常工作。尝试压缩文件，您将不会再看到错误。
-
另外，我发现服务器打开了新连接，但不要关闭旧连接。正如我在我的 PC 上所说的，它工作正常，在笔记本电脑上我需要再压缩一次。它与文件的大小和计算机的速度有一些联系......也可能发生你的一些功能，，返回无”（我在某处读过）。
