Example

This examples demonstrates the most basic usage of sprockets.mixins.http

from tornado import gen, ioloop, web
from sprockets.mixins import http


class RequestHandler(http.HTTPClientMixin, web.RequestHandler):

   @gen.coroutine
   def get(self, *args, **kwargs):
       response = yield self.http_fetch('https://api.github.com')
       if not response.ok:
           self.set_status(response.code)
       self.write(response.body)
       self.finish()


if __name__ == "__main__":
   app = web.Application([web.url(r'/', RequestHandler)])
   app.listen(8000)
   ioloop.IOLoop.current().start()

As with Tornado, to use the curl client which has numerous benefits:

from tornado import gen, httpclient, ioloop, web
from sprockets.mixins import http

httpclient.AsyncHTTPClient.configure(
    'tornado.curl_httpclient.CurlAsyncHTTPClient')


class RequestHandler(http.HTTPClientMixin, web.RequestHandler):

   @gen.coroutine
   def get(self, *args, **kwargs):
       response = yield self.http_fetch('https://api.github.com')
       if not response.ok:
           self.set_status(response.code)
       self.write(response.body)
       self.finish()


if __name__ == "__main__":
   app = web.Application([web.url(r'/', RequestHandler)])
   app.listen(8000)
   ioloop.IOLoop.current().start()
