使用django串流mp3文件，从< audio> [英] Streaming mp3 files with django, read from a page with <audio>

问题描述

我正在尝试使用一个小型应用程序来流式传输我的mp3文件与一个Web界面，我想到玩，并在python与django做服务器端。

I'm trying to make a small app to stream my mp3 files with a web interface, and I thought about playing with and do the server side in python with django.

我想要像/ stream / ID这样的网址来流传输与该ID相对应的mp3。
我在django中看到使用不同的方法为这些文件提供服务，最后一个我尝试的是一个描述这里

I want to have urls like /stream/ID to stream the mp3 corresponding to that ID. I made a view in django to serve these files using different methods, the last one I tried being the one described here

如果我从firefox访问/ stream / ID，直接用firefox-totem或一些插件播放mp3。如果我使用带有与源代码相同的URL的音频播放器的页面，它根本不起作用（使用通过apache提供的mp3文件的链接）。

If I access /stream/ID from firefox, it plays the mp3 directly with firefox-totem or some plugin like that. If I use the page with my audio player with the same url as the source it doesn't work at all (works with a link to an mp3 file served by apache).

这里是我的视图的代码（只发送一个测试文件）

here is the code of my view (only send one test file)

def stream(request):  
    resp =  HttpResponse(FileIterWrapper(open('/.../test.mp3',"rb")),mimetype='audio/mpeg')  
    resp['Content-Length'] = os.path.getsize("/.../test.mp3")  
    resp['Content-Disposition'] = 'filename=test.mp3'  
    return resp

我切割完整路径，这不是问题。

I cut the full path, it is not the problem.

当查看django runserver输出时，我注意到每次音频播放器尝试，我得到这两个错误，

When looking at the django runserver output, I noticed that each time the audio player tries, I get these 2 errors,

Traceback (most recent call last):

当我直接访问流网址时，没有问题/错误。

no problem/error when I acces the stream URL directly.

我在chrome（最新版本，ffmpeg -extra安装），它可以正常从apache的mp3，但超时使用流网址。

I tried the same in chromium (latest version, with ffmpeg-extra installed), it works fine with the mp3 from apache, but timeouts when using the stream url.

我尝试在响应中设置不同的标头，但没有成功。
我正在设置内容长度，内容类型和内容配置

I tried setting different headers in the response, but with no success. I'm currently setting the content-length, content-type and content-disposition

我正在寻找新的想法尝试。

I'm looking for new ideas to try.

感谢您的帮助！

推荐答案

您可以尝试使用 wireshark ，以便在正常工作时观察您的浏览器/媒体播放器/ apache。

You could try using wireshark to observe your browser/media player/apache while it works correctly.
