Example
This examples demonstrates the most basic usage of sprockets.mixins.http
from tornado import ioloop, web
from sprockets.mixins import http
class RequestHandler(http.HTTPClientMixin, web.RequestHandler):
async def get(self, *args, **kwargs):
response = await self.http_fetch('https://api.github.com')
if not response.ok:
self.set_status(response.code)
self.write(response.body)
if __name__ == "__main__":
app = web.Application([(r'/', RequestHandler)])
app.listen(8000)
ioloop.IOLoop.current().start()
As with Tornado, to use the curl client which has numerous benefits:
from tornado import httpclient, ioloop, web
from sprockets.mixins import http
httpclient.AsyncHTTPClient.configure(
'tornado.curl_httpclient.CurlAsyncHTTPClient')
class RequestHandler(http.HTTPClientMixin, web.RequestHandler):
async def get(self, *args, **kwargs):
response = await self.http_fetch('https://api.github.com')
if not response.ok:
self.set_status(response.code)
self.write(response.body)
if __name__ == "__main__":
app = web.Application([(r'/', RequestHandler)])
app.listen(8000)
ioloop.IOLoop.current().start()
