Simple stream file proxy with Flask and Requests

app.py

# -*- coding: utf-8 -*-

from flask import Flask
from flask import Response
from flask import stream_with_context

import requests

app = Flask(__name__)

@app.route('/<path:url>')
def home(url):
    req = requests.get(url, stream = True)
    return Response(stream_with_context(req.iter_content()), content_type = req.headers['content-type'])

if __name__ == '__main__':
    app.run()

Note that iter_content() uses a chunk_size of 1 byte by default which makes proxying large files pretty slow. In some cases req.iter_content(chunk_size=1024) will work better.

@thavelick Thanks, req.iter_content(chunk_size=1024) worked great!
