python requests return file-like object for streaming
Solution 1
There's an attribute Response.raw, which is already a file-like object.
resp = requests.get(url, stream=True)
resp.raw # is what you need
Using io.BytesIO(resp.content)
is not preferable since behind the scenes you're reading the same amount of data twice (also memory-wise): accessing resp.content
reads everything from the network stream, then io.BytesIO(resp.content)
is allocating again the same amount of memory, and then you read it from BytesIO object.
Solution 2
Look into the io module for using file-like objects.
Probably you could use io.BytesIO
which you can initialize with the Response.content
. Then instead of list of bytes you get a file-like object.
import io
resp = requests.get(url, stream=True)
obj.mp3 = io.BytesIO(resp.content)
Solution 3
Django's responsibility is to generate the HTML code that is then interpreted by the browser. The browser is what needs to be streaming the audio. You need to pass the mp3 url through Django templates that a player like http://www.jwplayer.com/ can then stream on the client side.

I have created a requests object like this:
obj.mp3 = requests.get('http://foo.com/bar.mp3', stream=True)
I thought that I could just feed this
obj.mp3
object into any audio player that expects a file or an URI, obviously this idea is wrong: nothing played. Below are the full code:#views.py class ArticleDetailView(DetailView): model = Article template_name = 'song.html' def get_object(self): obj = super(ArticleDetailView, self).get_object() #code to store mp3 url in obj.mp3 and other stuff if obj.mp3: obj.mp3 = requests.get(obj.mp3, stream=True).content return obj #song.html <div class="audio"> <audio src={{ article.mp3 }} type="audio/mpeg"> </div>
What is the correct way of treating return from
requests
as something that I can stream with a player? I know at least I can write theobj.mp3
to a file, then just point the player to the file location, but I am trying to avoid write the file to disk.Thanks,
