ERequests allows you to use Requests with Eventlet to make asyncronous HTTP Requests easily.

ERequests is a port to Eventlet of Kenneth Reitz's grequests (https://github.com/kennethreitz/grequests)

Usage is simple:

import erequests

urls = [
    'http://httpbin.org/delay/3',
    'http://www.heroku.com',
    'http://tablib.org',
    'http://python-requests.org',
    'http://kennethreitz.com'
]

Create a set of unsent Requests:

>>> rs = (erequests.get(u) for u in urls)

Send them all at the same time:

>>> erequests.map(rs)
[<Response [200]>, <Response [200]>, <Response [200]>, <Response [200]>, <Response [200]>]

Exception handling:

>>> def exception_handler(request):
>>>     return '%s' % request.exception
>>> rs = (erequests.get(u, timeout=1, exception_handler=exception_handler) for u in urls)
>>> erequests.map(rs)
["HTTPConnectionPool(host='httpbin.org', port=80): Request timed out. (timeout=1)", <Response [200]>, <Response [200]>, <Response [200]>, <Response [200]>]

In case of exception the exception_handler is called with the request as argument. The actual exception is found in request.exception.

Installation is easy with pip:

$ pip install erequests
