rest-server-example.c : A RESTful server example showing how to use the REST layer to develop server-side applications (possible to run it over either COAP or HTTP)
To use COAP as the underlying application protocol, one should define WITH_COAP = 1 in rest-example/Makefile. Otherwise, HTTP is used.
Look at the source code to see which resources are available. (check the RESOURCE macros in the code).
Each resource has a handler function which is called by the REST layer to serve the request.
(i.e. "helloworld" resource has a handler function named "helloworld_handler" which is called when a web service request is received for "helloworld" resource.)

Accessing the server from outside:
Start COOJA and load the simulation "rest-server-example.csc" by the following command.
> make TARGET=cooja rest-server-example.csc
After loading the cooja file, in another terminal connect to the COOJA simulation using tunslip6:
After loading the cooja file, open another another terminal pointing to the same directory and connect to the COOJA simulation using tunslip6:
>make connect-router-cooja
Now you need to use a COAP or HTTP client to interact with the COOJA nodes running REST code.
In this setting, two servers are available:
IP addresses are aaaa::0212:7402:0002:0202 and aaaa::0212:7403:0003:0303. COAP uses 61616, whereas HTTP uses 8080 port.
IP addresses are aaaa::0212:7402:0002:0202 and aaaa::0212:7403:0003:0303. COAP uses 61616, whereas HTTP uses 8080 port in default configuration.
HTTP Examples
You can use curl as an http client to interact with the COOJA motes running REST code.
