通过Nginx在Django中流式传输mp3文件

我有一个基于Django框架的网站。我通过Nginx网络服务器（uWSGI，Django，Nginx）运行网站。我想用Accept-Ranges标题在我的网站上传输mp3文件。我想用Nginx来提供我的mp3文件。我需要我的API看起来像这样通过Nginx在Django中流式传输mp3文件

http://192.168.1.105/stream/rihanna

这必须通过部分下载（Accept-Ranges）返回mp3文件。我的MP3文件存储在：/家庭/泊坞窗/代码/应用/媒体/数据/ 当我运行带有这些配置的服务器和浏览到192.168.1.105/stream/rihanna，返回Django的404

我Nginx的CONF：

# mysite_nginx.conf 

# the upstream component nginx needs to connect to 
upstream django { 
server unix:/home/docker/code/app.sock; # for a file socket 
# server 127.0.0.1:8001; # for a web port socket (we'll use this first) 
} 

# configuration of the server 
server { 
# the port your site will be served on, default_server indicates that this server block 
# is the block to use if no blocks match the server_name 
listen  80 default; 
include /etc/nginx/mime.types; 
# the domain name it will serve for 
server_name .example.com; # substitute your machine's IP address or FQDN 
charset  utf-8; 

# max upload size 
client_max_body_size 75M; # adjust to taste 

# Django media 
location /media { 
    autoindex  on; 
    sendfile  on; 
    sendfile_max_chunk  1024m; 
    internal; 
    #add_header X-Static hit; 
    alias /home/docker/code/app/media/; # your Django project's media files - amend as required 
} 
location /static { 
    alias /home/docker/code/app/static/; # your Django project's static files - amend as required 
} 

# Finally, send all non-media requests to the Django server. 
location/{ 

    uwsgi_pass django; 
    include  /home/docker/code/uwsgi_params; # the uwsgi_params file you installed 
    } 
}

我views.py：

def stream(request, offset): 
    try: 

      mp3_path = os.getcwd() + '/media/data/' + offset + '.mp3' 
      mp3_data = open(mp3_path, "r").read() 



except: 
    raise Http404() 





response = HttpResponse(mp3_data, content_type="audio/mpeg", status=206) 
response['X-Accel-Redirect'] = mp3_path 
response['X-Accel-Buffering'] = 'no' 
response['Content-Length'] = os.path.getsize(mp3_path) 
response['Content-Dispostion'] = "attachment; filename=" + mp3_path 
response['Accept-Ranges'] = 'bytes'

我想Nginx的服务于这个文件。我真的需要启用Accept-Ranges。

我Settings.py：

# Build paths inside the project like this: os.path.join(BASE_DIR, ...) 
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

我的问题是：它不工作，并返回Django的错误404网页。

Django是否需要能够真正控制谁可以看到这些文件？如果不是只把它们放到你的静态文件目录中，让Nginx处理流媒体。你的表现也会更好。 –

@AndréBorie谢谢。我的管理文件在/静态/路径。当我想浏览它们时，Nginx返回404。我真的不知道为什么。即使在我的网站的静态路径中，Nginx也会返回404错误。 –

首先，我没有将Nginx配置文件复制到可用站点路径。因为它，它不起作用。在我views.py：

response = HttpResponse(mp3_data, content_type="audio/mpeg", status=206) 
response['X-Accel-Redirect'] = mp3_path

这两条线必须改为：

response= HttpResponse('', content_type="audio/mpeg", status=206) 
response['X-Accel-Redirect'] = '/media/data/' + offset + '.mp3'

我希望它可以帮助别人谁拥有了这个问题。
