Mulib Examples

These are some short examples to give a flavor of using mulib.

hello world

The following program will bring up a webserver listening on port 8080 which can respond to a single request, "GET /", with the response "hello, world":

from mulib import mu

from eventlet import api, httpd

class HelloWorld(mu.Resource):
   def handle_get(self, req):
       req.write("hello, world\n")

root = HelloWorld()

httpd.server(
   api.tcp_listener(('0.0.0.0', 8080)),
   mu.SiteMap(root))


stacked

Stacked is a pure REST server, and you can use it to traverse native python objects like dicts.

from mulib import mu

from eventlet import api, httpd

root = {:'hello, world\n',
        'other':"hello, other\n"}

httpd.server(api.tcp_listener(('0.0.0.0', 8080)), mu.SiteMap(root))

You can then access this dictionary as a REST resource, e.g.

> curl http://localhost:8080/     
hello, world
> curl http://localhost:8080/other
hello, other
> curl -X PUT -d "the new data" http://localhost:8080/third
> curl http://localhost:8080/third
the new data

Mu/stacked can do content negotiation:

> curl -X PUT -H "Content-type: application/json" -d '{"hi": "there"}' http://localhost:8080/fourth
> curl http://localhost:8080/fourth/hi
there
> curl -H "Accept: application/json" http://localhost:8080/fourth
{'hi': 'there'}

Note: This means that anyone who has access to your stacked web service can modify the data in your process! In the future we might have a 'read-only' implementation.
