@ -10,52 +10,7 @@ Sometimes, you want to integrate Gunicorn with your WSGI application. In this
case, you can inherit from :class:`gunicorn.app.base.BaseApplication`.
Here is a small example where we create a very small WSGI app and load it with a
custom Application::
custom Application:
#!/usr/bin/env python
import gunicorn.app.base
def handler_app(environ, start_response):
response_body = 'Works fine'
status = '200 OK'
response_headers = [
('Content-Type', 'text/plain'),
('Content-Length', str(len(response_body)))
]
start_response(status, response_headers)
return [response_body]
class StandaloneApplication(gunicorn.app.base.BaseApplication):
def __init__(self, app, options=None):
self.options = dict(options or {})
self.application = app
super(StandaloneApplication, self).__init__()
def load_config(self):
tmp_config = map(
lambda item: (item[0].lower(), item[1]),
self.options.iteritems()
)
config = dict(
(key, value)
for key, value in tmp_config
if key in self.cfg.settings and value is not None
)
for key, value in config.iteritems():
self.cfg.set(key.lower(), value)
def load(self):
return self.application
if __name__ == '__main__':
options = {
'bind': '%s:%s' % ('127.0.0.1', '8080'),
'workers': 4,
# 'pidfile': pidfile,
}
StandaloneApplication(handler_app, options).run()
