Simple wrapper around gevent's wsgi server.Adds simple regex routing, error handling, and json/jsonp handling.

Project description

gserver 0.2.0

Simple wrapper around gevent that provides a basic routing engine and JSON/JSONP handling.

Here’s a simple usage example:

from gevent.monkey import patch_all; patch_all()
from gevent import queue

from gserver.routes import Routes
from gserver.request import parse_vals
from gserver.wsgi import WSGIServer

routes = Routes()
route = routes.route
route_json = routes.route_json

@route("^/example/$")
def example(req):
    return "hello"

@route("^/poll/$")
def poll(request):
    yield ' ' * 1000
    yield "hello"
    sleep(5)
    yield "goodbye" # connection is closed at this point

@route("^/queue/$")
def q(request):
    def process(b):
        b.put("<div>1</div>")
        sleep(1)
        b.put("<div>2</div>")
        sleep(1)
        b.put("<div>3</div>")

    body = queue.Queue()
    body.put(' ' * 1000)
    body.put("<!doctype html><html><head><title>hola</title><head><body>\n")
    gevent.spawn(process, body)
    return body

@route_json("^/example/(?P<name>\w+)/$", method="GET,POST")
def example_name(request, name=None):
    data = request.query_data
    if request.method == "POST":
        data = request.form_data
    query_age, query_height = parse_vals(data, "age", "height")

    return { "name": name,
             "age": query_age,
             "height": query_height }

if __name__ == "__main__":
    server = WSGIServer(('', 9191), routes, log=None)
    server.serve_forever()
