Joh*_*ski 5 php notifications ios
我正在努力通过GCM获取后台通知以使用IOS - 非后台通知已经正常工作.以下是我整合背景通知的步骤:
以下是委托函数的代码:
func application( application: UIApplication,
didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler handler: (UIBackgroundFetchResult) -> Void) {
println("Notification received2: \(userInfo)")
GCMService.sharedInstance().appDidReceiveMessage(userInfo);
NSNotificationCenter.defaultCenter().postNotificationName(messageKey, object: nil,
userInfo: userInfo)
handler(UIBackgroundFetchResult.NoData);
}

这是服务器上的PHP脚本的代码:
<?php
$regId = $_GET["regId"];
$message = $_GET["message"];
$data = array( 'price' => $message, 'sound' => 'default', 'body' => 'helloworld', 'title' => 'default', 'badge' => 12, 'content-available' => 1);
$ids = array( $regId);
sendGoogleCloudMessage( $data, $ids );
function sendGoogleCloudMessage( $data, $ids )
{
$apiKey = THE-API-KEY-THAT-I-AM-USING;
$url = 'https://android.googleapis.com/gcm/send';
$post = array(
'registration_ids' => $ids,
'data' => $data,
'content-available' => 1,
);
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $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( $post ) );
$result = curl_exec( $ch );
if ( curl_errno( $ch ) )
{
echo 'GCM error: ' . curl_error( $ch );
}
curl_close( $ch );
echo $result;
}
?>

我已经尝试通过内部"数据"数组和外部"post"数组发送内容可用标志,我通过将其添加到两者来指示.
fetchCompletionHandler函数不接收该消息,而是等待应用程序再次处于活动状态并由正常应用程序接收:didRecieveRemoteNotification函数.可能是因为没有通过后台功能收到通知的原因?
您应该向 GCM 提供content_available,而不是content-available(如 APN 中),并且您将能够在后台接收推送通知。

PS - 不到五分钟前我遇到了完全相同的问题。我们应该更仔细地阅读文档......
