我正在使用Urban Airship (v3) API将消息推送到 Android/iPhone/Blackberry，希望很快会推送到 Windows 手机。我对此概不负责；相反，我正在设置后端以允许用户发送广播。
另一个人构建了原始后端，但我选择从下到上重新构建它以添加一些额外的功能。除了广播部分的整个推送之外，一切都在其中进行。嗯，它有点工作；让我解释：
提交表单后，数据通过 MYSQL 进入数据库，然后使用 mysql_fetch_id() 获取新 id 并将该 id 放入名为 sendBroadcast 的 PHP 函数中。它如下所示：
function sentBroadcast($id){
$alertinfo = getAlertInfo($id);//this just gets all the data matching the id
$alert = mysql_fetch_assoc($alertinfo);
//these just get extra values
$organization = getOrganizationById($alert['broadcast_organization_id']);
$cityinfo = getCityInfo($organization['organization_city_id']);
$city = mysql_fetch_assoc($cityinfo);
// Create Airship object
$airship = new Airship(APP_KEY, APP_MASTER_SECRET);
$apiurl = "https://go.urbanairship.com/api/location/?q=".str_replace(" ","",strtolower($city['city_name']));
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiurl);
curl_setopt($ch, CURLOPT_USERPWD, APP_KEY.":".APP_MASTER_SECRET);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close ($ch);
$json = json_decode($output);
$locationid = "all";
if(count($json->features) > 0){
$locationid = $json->features[0]->id;
}
//send the message
$broadcasttype = "";
if($alert['broadcast_broadcasttypeother'] != ""){
$broadcasttype = $alert['broadcast_broadcasttypeother'];
}
else {
//this just gets data, nothing to see here
$broadcasttype = getCategoryInfo($alert['broadcast_broadcasttype_id'],'broadcasttype_name');
}
$message = html_entity_decode($broadcasttype)."\r\n".html_entity_decode($organization['organization_name'])."\r\n". html_entity_decode($alert['broadcast_subject']);
$blackberry_message = html_entity_decode($organization['organization_name'])."\r\n". html_entity_decode($alert['broadcast_subject']);
//calc as UTC
$timestamp = strtotime($alert['broadcast_sentdatetime']) + strtotime("+1 minute"); //add an hour
$offset = new DateTime(date("Y-m-d H:i:s T",$timestamp));
$offset->setTimezone(new DateTimeZone('UTC'));
$minutes_to_add = 10;
$time = new DateTime($alert['broadcast_sentdatetime']);
$time->add(new DateInterval('PT' . $minutes_to_add . 'S'));
$stamp = $time->format('Y-m-d H:i:s');
//echo $stamp;
$broadcast_message = array(
'schedule' => array("scheduled_time" => $stamp),
'push' => array("audience" => "all",
"notification" => array("alert" => $message),
"device_types" => array()
),
);
$device_types = array();
$device_types[] = "ios";
$device_types[] = "android";
$device_types[] = "blackberry";
$broadcast_message["push"]["device_types"] = $device_types;
if(in_array("ios", $device_types)){
$broadcast_message["push"]["notification"]["ios"] = array("sound" => "police.mp3", "extra" => array("id"=>$alert['broadcast_id']), "badge" => "+1");
}
if(in_array("android", $device_types)){
$broadcast_message["push"]["notification"]["android"] = array("extra"=>array("id"=>$alert['broadcast_id']));
}
if(in_array("blackberry", $device_types)){
$broadcast_message["push"]["notification"]["blackberry"] = array("content-type"=>"text/plain","body"=> json_encode(array("id"=>$alert['broadcast_id'], "body"=>$blackberry_message, "type"=>$broadcasttype)));
}
$data_string = json_encode($broadcast_message);
$apiurl = "https://go.urbanairship.com/api/schedules/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiurl);
curl_setopt($ch, CURLOPT_USERPWD, APP_KEY.":".APP_MASTER_SECRET);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-type: application/json',
'Accept: application/vnd.urbanairship+json; version=3;',
'Content-Length: ' . strlen($data_string)
));
$json = curl_exec($ch);
$output = json_decode($json, true);
if(!is_array($output) || empty($output["ok"])){
echo "<h1>ERROR: (".(isset($output["error"]) ? $output["error"] : "An unknown error has occurred while trying to send your message.").")</h1>";
echo $data_string;
print_r($output);
$error = true;
}
curl_close ($ch);
$debug = false;
if($debug || $error){
if($error) echo "<!--";
var_dump($broadcast_message);
echo "<hr><br>";
echo $json."<hr><br>";
echo "<pre>";
print_r($output);
echo "</pre>";
if(!empty($output['ok'])){
//maybe we should save the status, or the json in the db.
echo 'yay it sent';
}
if($error) echo "-->";
}
if($error){
exit;
}
}//end sendBroadcast
当我执行此查询时，遇到“无法解析正文请求正文”错误。这不是很有帮助，所以我打印了响应（在“if(!is_array($output) || empty($output["ok"])){"下查看）。我收到以下错误消息：
Array ( [ok] => [error] => Could not parse request body. [error_code] => 40700 [details] => Array ( [error] => Cannot schedule for the past 2013-10-12T06:46:00.000Z ) [operation_id] => 6fde4fa0-4b64-11e3-8903-90e2ba0253a0 )
我得到的错误是“无法安排过去”，但是在提交时，它是未来。我开始做一些研究并读到我必须将其设置为 UTC 时间。话虽如此，无论我现在是什么时间，UTC 时间总是过去 6 小时，所以我必须将其转换为 UTC。
所以，我这样做了，消息出去了，手机收到了，一切都很顺利。除非我们去阅读该消息：然后我们收到一条错误消息，指出该消息已被删除。
我们没有删除它，所以我想可能（还不到 6 个小时）用户的手机将来会收到新的广播，但他们现在收到了警报。该警报尚不可见，因此会引发错误。至少我是这么认为的；还不到6个小时，所以我无法证明这一点。
我的问题是：我如何告诉 Urban Airship 我想要一个立即发布的帖子，而不必在当前时间上增加 6 小时才能使其成为“现在”，并且实际上让手机在正确的时间？
我联系了 UA，但他们说“预计会延迟一周回复您”（不急，是吗？），我搜索了错误代码 (40700)，但一无所获。然后我给制作原版的那个人发了电子邮件，他只说“UTC 非常重要”。谢谢你。
如果有人可以帮助我，我将非常感激。
谢谢你。
哦，如果有人想知道，我提交的 json 如下所示：
{"schedule":{"scheduled_time":"2013-10-12 06:46:00"},"push":{"audience":"all","notification":{"alert":"Message\r\nKenton Industries\r\nKenton Test","ios":{"sound":"police.mp3","extra":{"id":"406"},"badge":"+1"},"android":{"extra":{"id":"406"}},"blackberry":{"content-type":"text\/plain","body":"{\"id\":\"406\",\"body\":\"Kenton Industries\\r\\nKenton Test\",\"type\":\"Message\"}"}},"device_types":["ios","android","blackberry"]}}
谢谢 ：）
