[luci] How to communicate with the Json Rpc API

[Clemens John]

Hi,

I read the Documentation on JsonRpc on http://luci.freifunk-
halle.net/Documentation/JsonRpcHowTo but I didn´t unterstand how to do it.

Basically I want to get the uptime of a machine.
How do I do that?

I tried "http://mymachiene/cgi-bin/luci/rpc/sys/uptime" in my browser but that 
didn´t worked.

Thanks
Clemens
