Urban Airship push: Response: Got negative response from server: 0 - php

Question

I am trying to send push notification to my Android app from my server. But it is throwing error Payload: {"audience":"all","notification":{"android":{"alert":"PHP script test "}},"device_types":["android"]} Response: Got negative response from server: 0.
Below is the source code
<?php
define('APPKEY','**************Mw'); // Your App Key
define('PUSHSECRET','**********Low'); // Your Master Secret
define('PUSHURL', 'https://go.urbanairship.com/api/push/');
$contents = array();
$contents['alert'] = "PHP script test";
$notification = array();
$notification['android'] = $contents;
$platform = array();
array_push($platform, "android");
$push = array("audience"=>"all", "notification"=>$notification, "device_types"=>$platform);
$json = json_encode($push);
echo "Payload: " . $json . "\n"; //show the payload
$session = curl_init(PUSHURL);
curl_setopt($session, CURLOPT_USERPWD, APPKEY . ':' . PUSHSECRET);
curl_setopt($session, CURLOPT_POST, True);
curl_setopt($session, CURLOPT_POSTFIELDS, $json);
curl_setopt($session, CURLOPT_HEADER, False);
curl_setopt($session, CURLOPT_RETURNTRANSFER, True);
curl_setopt($session, CURLOPT_HTTPHEADER, array('Content-Type:application/json', 'Accept: application/vnd.urbanairship+json; version=3;'));
$content = curl_exec($session);
echo "Response: " . $content . "\n";
// Check if any error occured
$response = curl_getinfo($session);
if($response['http_code'] != 202) {
echo "Got negative response from server: " . $response['http_code'] . "\n";
} else {
echo "Wow, it worked!\n";
}
curl_close($session);
?>

<?php
// DEVELOPMENT PUSH DETAILS
define('APPKEY','XXXXXXXXXXXXXXXXXXX');
define('PUSHSECRET', 'XXXXXXXXXXXXXXXXXXX'); // Master Secret
define('PUSHURL', 'https://go.urbanairship.com/api/push/');
/*
// PRODUCTION PUSH DETAILS
define('APPKEY','XXXXXXXXXXXXXXXXXXX');
define('PUSHSECRET', 'XXXXXXXXXXXXXXXXXXX'); // Master Secret
define('PUSHURL', 'https://go.urbanairship.com/api/push/');
*/
$push = array();
$push['aliases'] = $aliases; // Using alias that is set from the javascript after the device has registered to urban airship
$push['aps'] = array("badge"=>"+1", "alert" => $message); // for iphone
$push['android'] = array("alert"=>$message); // for android
$json = json_encode($push);
echo "Payload: " . $json . "\n"; //show the payload
$session = curl_init(PUSHURL);
curl_setopt($session, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($session, CURLOPT_USERPWD, APPKEY . ':' . PUSHSECRET);
curl_setopt($session, CURLOPT_POST, True);
curl_setopt($session, CURLOPT_POSTFIELDS, $json);
curl_setopt($session, CURLOPT_HEADER, False);
curl_setopt($session, CURLOPT_RETURNTRANSFER, True);
curl_setopt($session, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
$content = curl_exec($session); // $content has all the data that came back from urban airship..check its contents to see if successful or not.
// Check if any error occured
$response = curl_getinfo($session);
if($response['http_code'] != 200) {
$status = $response['http_code'];
echo "Got negative response from server: " . $response['http_code'] . "\n";
} else {
$status = 'ok';
}
curl_close($session);
?>
Here, $aliases is array type. It is list of aliases. $message is notification which you want to push. Assign value properly in this two variable. It will work..

According to the HTTP standards, you should include a space between "Content-Type:" and "application/json". Probably the Google server is not interpreting your content-type correctly making it an incorrect request ( It could even be it is rejected due to the Accept: values on the server side ).
Correct your content-type header and try again
