Question

I am creating the Android application where C2DM push notification is used. But i have a problem in creating the php code to use c2dm for sending messages. please guide me how to use the php code to send the messages. Actually there is a problem regarding this that how to get client auth token. I have seen the http://code.google.com/android/c2dm/index.html#server url but according to this i have created the android application and i got the registration id also and i also send to the user but how server uses this to send the application.
is there anything needed for the server from the android device to send the messages?.

Answer 1

To register your own server system and obtain the Authorise Tokens (this is what Cpt. Ohlund proposed):
function googleAuthenticate($username, $password, $source="Company-AppName-Version", $service="ac2dm") {
session_start();
if( isset($_SESSION['google_auth_id']) && $_SESSION['google_auth_id'] != null)
return $_SESSION['google_auth_id'];
// get an authorization token
$ch = curl_init();
if(!ch){
return false;
}
curl_setopt($ch, CURLOPT_URL, "https://www.google.com/accounts/ClientLogin");
$post_fields = "accountType=" . urlencode('HOSTED_OR_GOOGLE')
. "&Email=" . urlencode($username)
. "&Passwd=" . urlencode($password)
. "&source=" . urlencode($source)
. "&service=" . urlencode($service);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// for debugging the request
//curl_setopt($ch, CURLINFO_HEADER_OUT, true); // for debugging the request
$response = curl_exec($ch);
//var_dump(curl_getinfo($ch)); //for debugging the request
//var_dump($response);
curl_close($ch);
if (strpos($response, '200 OK') === false) {
return false;
}
// find the auth code
preg_match("/(Auth=)([\w|-]+)/", $response, $matches);
if (!$matches[2]) {
return false;
}
$_SESSION['google_auth_id'] = $matches[2];
return $matches[2];
}
To send a message to a phone:
// $msgType: all messages with same type may be "collapsed": if multiple are sent,
// only the last will be received by phone.
function sendMessageToPhone($authCode, $deviceRegistrationId, $msgType, $messageText) {
$headers = array('Authorization: GoogleLogin auth=' . $authCode);
$data = array(
'registration_id' => $deviceRegistrationId,
'collapse_key' => $msgType,
'data.message' => $messageText //TODO Add more params with just simple data instead
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://android.apis.google.com/c2dm/send");
if ($headers)
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}

I've created an example in my blog in working with Android C2DM. I use Zend Framework and a custom component that I wrote out. It should give you the basic information that you will need in order to handle your Android C2DM implementation in PHP.

Answer 3

Check this out: http://www.toppa.com/2010/google-clientlogin-php-example/
Otherwise I will get back to you, as I will try C2DM later this week.

Answer 4

As C2DM has been officially deprecated (google c2dm)
I recommend using the new GCM API as described in the following link:
GCM Php implementation

I have tried using the php code that was accepted as the correct answer but it is not working.

I found the same code in the following link
