您好我正在使用以下代码发送推送通知。我在这段代码中遇到了问题。
<?php
class GCMPushMessage
{
var $url = 'http://android.googleapis.com/gcm/send';
var $serverApiKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxx";
var $devices = array();
function setDevices($deviceIds)
{
if (is_array($deviceIds)) {
$this->devices = $deviceIds;
} else {
$this->devices = array(
$deviceIds
);
}
}
function send($message)
{
if (!is_array($this->devices) || count($this->devices) == 0) {
$this->error("No devices set");
}
if (strlen($this->serverApiKey) < 8) {
$this->error("Server API Key not set");
}
$fields = array(
'registration_ids' => $this->devices,
'data' => array(
"msg" => $message
)
);
$headers = array(
'Authorization: key=' . $this->serverApiKey,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $this->url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
$this->StripResponseFromGCM(json_decode($result));
// Close connection
curl_close($ch);
return $result;
}
function error($msg)
{
echo "Android send notification failed with error:";
echo "\t" . $msg;
exit(1);
}
function StripResponseFromGCM($response)
{
//canonicalID's are the
if ($response->failure == 0 && $response->canonical_ids == 0)
return;
for ($i = 0; $i < sizeof($response->results); $i++) {
if (isset($response->results[$i]->registration_id)) { //if new registrationID is sent as canonicalID
//update this registrationID in the database
} else if ($response->results[$i]->error == "Unavailable") {
// user with index == $i is unavailable
} else if ($response->results[$i]->error == "InvalidRegistration") {
// user with index == $i has InvalidRegistration ID
} else if ($response->results[$i]->error == "NotRegistered") {
// user with index == $i is not registered
}
}
}
}
$msg = array(
'data' => array(
'msg' => 'just a simple message'
)
);
require_once('connection.php');
$sql = mysql_query("select gcmid from gcmid");
$new_array = mysql_fetch_array($sql);
print_r($new_array);
$obj = new GCMPushMessage();
$obj->setDevices($new_array);
$obj->send($msg);
?>
如果我在setDevices
方法中放入一个id,那么它工作正常,但如果我
从数据库中获取gcm ID并将其传递给方法setDevices
然后代码无效。它假设向设备发送推送通知但它无法正常工作。
