Installing

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

$ npm install js-middleware-for-mobile-agents

API

var api = require('./lib/Api.js')

Mobile agent structure

  exports.runAgent = function(){
    var api = this._api;
    console.log('Example with API 001');
  };

Usage examples

GetHostName function

  api.getHostName(function(err,result) {
    if (err) {
      console.log('Error: ' + err);
    } else {
      console.log('Host name for this device: ' + result);
    }
  });

GetAvailableHosts function

    api.getAvailableHosts(function(err,result) {
    if (err) {
        console.log('Error: ' + err);
    } else {
          console.log('Host List available: ');
        Object.keys(result).forEach(function (index) {
          console.log(result[index]);
          });
    }
    });

MoveTo function

    api.moveTo(this,'Host# 2',function(err,result){
      if (err) {
            console.log('Error: ' + err);
        } else {
            console.log('Result: ' + result);
        }
    });

Example example 1

exports.runAgent = function() {
  /*
  * Custom Code begin
  */
  this._name = "Scenario 001";
  var agent = this;
  console.log("Hello, World!");
  var hostList = ["Host# 1(::ffff:192.168.0.101)", "Host# 2(::ffff:192.168.0.103)", "Host# 3(::ffff:192.168.0.106)", "Host# 4(::ffff:192.168.0.105)", "Host# 5(::ffff:192.168.0.102)"];
  var host = "Host# 2(::ffff:192.168.0.101)";
  var api = this._api;
  var lastHost = this._lastHost;
  var newhost = 0;
  if (lastHost != NaN && lastHost != undefined) {
    newhost = (lastHost + 1);
  }
  this._lastHost = newhost;
  var next_host = hostList[newhost];
  var agent = this;
  setTimeout(function() {
      api.moveTo(agent, next_host, function(err, result) {
        if (err) {
          console.log('Error: ' + err);
        } else {
          console.log('\033[2J');
        }
      });
  },5000);
  /*
  * Custom code end
  */
};

Agent Example 2

exports.runAgent = function() {
  /*
  * Custom Code begin
  */
  this._name = "Scenario 002";
  var agent = this;
  console.log("Hello, World!");
  var host;
  var api = this._api;
  setTimeout(function() {
      api.getRandomHost(function(err, result) {
          if (err) {
            console.log('Error: ' + err);
          } else {
            host = result;
                api.moveTo(agent, host, function(err, result) {
                  if (err) {
                    console.log('Error: ' + err);
                  } else {
                    console.log('\033[2J');
                  }
                });
          }
      });
  },5000);
  /*
  * Custom code end
  */
};
