将音频文件加载到模板会导致 ConnectionResetError: [Errno 54] Connection reset by peer (Django, Python)

Question

我正在使用 Django 制作音频播放器 webapp。音频文件由管理员通过将文件添加到我的媒体目录的模型上传。然后在我的模板中，音频文件与单独的音频播放器一起显示。

{% for song in songs %}
   <audio class="player" controls>
      <source src="{{ song.audio_file.url }}" type="audio/wav">
   </audio>
{% endfor %}

现在，网站按预期运行。音频播放器都变得可见并且工作正常。但是在我的终端中，每次加载页面时都会出现这种类型的错误（取决于要显示的音频文件的数量，例如，如果只有一个文件，我会得到这个）：

[13/Dec/2019 12:03:31] "GET /media/ap/song.wav HTTP/1.1" 200 1626112

    return self._sock.recv_into(b)
ConnectionResetError: [Errno 54] Connection reset by peer

这可能是什么原因？将不胜感激。

您可以使用此代码可能会有所帮助：

{% for song in songs %}
   <audio class="player" controls>
      <source src="{% if song.audio_file %}{{ song.audio_file.url }} {% endif %}" type="audio/wav">
   </audio>
{% endfor %}
