Example – Using Deferreds¶
And of course, this is Twisted. So there is a wealth of APIs that return a Deferred. A Deferred may also be returned from handler functions and their result will be used as the response body.
Here is a simple Google proxy, using treq (think Requests, but using Twisted):
import treq from klein import Klein app = Klein() @app.route('/', branch=True) def google(request): d = treq.get(b'https://www.google.com' + request.uri) d.addCallback(treq.content) return d app.run("localhost", 8080)
