Using Dweet

getDweet.js 20 Aug2016
Incorporates the Dweet example into code that connects the ESP8266 to WiFi.
Setup parameters at the beginning of the code:

//set DweetID to a unique value
var DweetID="esp0912";

// Select Espruino Bd or Pico hardware
//var Hardware=0; //Espruino board
var Hardware =1; //PICO

//setup WiFi access parameters
var SSID="xxxx";
var 

On the IOT page
http://www.espruino.com/IoT+Services
the link “quite a lot” returns a “Nothing out there” error

Note that the data are appended to the URL in the putDweet() function.

  var options = {
    host: 'dweet.io',
    port: '80',
    path:'/dweet/for/'+dweet_name+"?"+data,
    method:'POST'
  };

But in the Cubitic example the data (content) is not added to the end of the URL in the header but is sent after the header in the last line the function by the function call end(content).

function putCubitic(event, data) {
  content = JSON.stringify(data);
  var options = {
    host: 'api.cubitic.io',
    port: '80',
    path:'/v1/event/'+event,
    method:'POST',
    headers: { 
      "Content-Type":"application/json",
      "cubitic-appid":CUBITIC.APPID, 
      "Authorization":"Bearer "+CUBITIC.TOKEN,
      "Content-Length":content.length 
    }
  };
  require("http").request(options, function(res)  {
    var d = "";
    res.on('data', function(data) { d+= data; });
    res.on('close', function(data) {
      console.log("Closed: "+d);
    });
  }).end(content);
}
