Release v0.2.0.
treq depends on Twisted>=12.1.0 and optionally pyOpenSSL.
All example code depends on Twisted>=12.3.0.
requests by Kenneth Reitz is a wonderful library. I want the same ease of use when writing Twisted applications. treq is not of course a perfect clone of requests. I have tried to stay true to the do-what-i-mean spirit of the requests API and also kept the API familiar to users of Twisted and twisted.web.client.Agent on which treq is based.
Installation:
pip install treq
1 2 3 4 | def main(reactor, *args):
d = treq.get('http://httpbin.org/get')
d.addCallback(print_response)
return d
|
Full example: basic_get.py
1 2 3 4 5 6 | def main(reactor, *args):
d = treq.post('http://httpbin.org/post',
json.dumps({"msg": "Hello!"}),
headers={'Content-Type': ['application/json']})
d.addCallback(print_response)
return d
|
Full example: basic_post.py
Initially when I started off working on treq I thought the API should look exactly like requests except anything that would involve the network would return a Deferred.
Over time while attempting to mimic the requests API it became clear that not enough code could be shared between requests and treq for it to be worth the effort to translate many of the usage patterns from requests.
With the current version of treq I have tried to keep the API simple, yet remain familiar to users of Twisted and its lower-level HTTP libraries.
Even though mimicing the requests API is not a goal, supporting most of it’s features is. Here is a list of requests features and their status in treq.
