Request

This is a message type, which gets a reply with a response type message.
Example:
const network = require('ocore/network.js');
const ws = network.getInboundDeviceWebSocket(device_address);
​
// function parameters: websocket, command, params, bReroutable, callback
var tag = network.sendRequest(ws, 'get_witnesses', null, false, getParentsAndLastBallAndWitnessListUnit);
​
function getParentsAndLastBallAndWitnessListUnit(ws, req, witnesses) {
  var params = {
    witnesses: witnesses
  };
  network.sendRequest(ws, 'light/get_parents_and_last_ball_and_witness_list_unit', params, false,
    function(ws, req, response) {
      console.log(response);
    }
  );
}
​
//you can have your own timeout logic and delete a pending request like this
setTimeout(function() {
  var deleted = network.deletePendingRequest(ws, tag); // true if request was deleted
}, 30*1000);
Following is a list of request type JSON messages that are sent over the network:
