在流中断管

标签: python django stream

我有一个Django项目我正在研究我想要流式传输一些mp3文件的地方。

我有同样的问题: Streaming mp3 files with django, read from a page with <audio>

让我解释一下:我希望使用Django流式传输ogg ,并在html页面中使用<audio>标记

我有一个类似domain.tld/song/show/X/的网址,其中X是我的歌曲的ID。 我可以使用VLC(直接使用文件路径)进行流式传输,我可以在测试期间流式传输,(我写下我收到的内容并使用VLC读取它)。

但是,当我打开浏览器并加载我的主页domain.tld并且<\audio\>使用网址domain.tld/song/show/1/加载时,我得到一个破损的大管,好像我的客户关闭了连接。

我在其他帖子上看到,当他们将服务器投入生产时,一些问题得到了解决。所以我在djangoproject.com上将我的应用程序推送到服务器上,使用apache和django.wgsi之类的。

我正在使用Django 1.5版在Debian 7上运行python 2.7.3。 那里有我的代码:

乐曲/ views.py

def playAudioFile(request, pk):
    f = get_stream_song(pk)# return a pipe from pipes.Template
    l = f.read() # the file is an ogg get by pydub.com
    f.close()
    size_read = 550000
    sr = size_read
    while sr == size_read:
        print "rep"
        r = l[:size_read]
        l=l[size_read:]
        sr = len(r)
        yield r
    time.sleep(0.1) 

#url : ~/song/show/X/
#@login_required
def show_song(request, pk):
        return StreamingHttpResponse(playAudioFile(request, pk), mimetype='audio/ogg',)

在我的HTML中,我就是这样:

 <audio controls height="100" width="100" preload="auto">
    <source src="/.../song/show/1/" type="audio/ogg">
    <embed height="50" width="100" src="/.../song/show/1/">
  </audio>

错误如下:

Traceback (most recent call last):
  File "/usr/lib/python2.7/wsgiref/handlers.py", line 86, in run
    self.finish_response()
  File "/usr/lib/python2.7/wsgiref/handlers.py", line 127, in finish_response

    self._sock.sendall(view[write_offset:write_offset+buffer_size])
error: [Errno 32] Broken pipe

每次尝试流式传输时都会得到两次。
