09:46:05 # Life Sending GCM send message from nodejs. I wanted to send a message from emacs, but it seemed to be relatively difficult to send HTTPS POST request from emacs, so I just decided to use handy nodejs. The attached 'data' is attached to intent as extra, so it can be extracted by intent.getExtras.getString("message") in IntentService#onHandleIntent()

var https = require('https');

message = {
    // Registration IDs come from application after registration.
    registration_ids: [
	// From XXX
	'xxxxx',
    ],
    data: {
	// This is the actual message
	message: 'hello world'
    }
}

var options = {
    hostname: 'android.googleapis.com',
    port: 443,
    path: '/gcm/send',
    method: 'POST',
    headers: {
	// Secret from dashboard.
	'Authorization': 'key=xxx',
	'Content-Type': 'application/json'}
};

req = https.request(options, function(res) {
  console.log("Got response: " + res.statusCode);

  res.on('data', function(d) {
    process.stdout.write(d);
  });

}).on('error', function(e) {
  console.log("Got error: " + e.message);
});

req.write(JSON.stringify(message));
req.end();
