python requests return file-like object for streaming

Question

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

``` 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 the `obj.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,

Accepted Answer

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.
