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
. You invoke these special capabilities of Stacked by placing a python dict or list in the resource hierarchy instead of a mu.Resource, in this case at the root.
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.
