IOS推送通知：发送此有效负载时没有任何推动

Question

When i am trying to send the following payload for generating a push notification on iphone, i receive a successful message but i do not receive any push notifications.

I want to know if this payload in valid format?

{
    "aps": {
        "alert": "green commented on your post: 'push post for tim'. Comment is: hey hi!",
        "sound": "default"
    },
    "type": "comment",
    "post": {
        "post_id": "168",
        "post_title": "push post for tim",
        "post_content": "testing push",
        "post_status": "1",
        "is_favorite": "0",
        "post_comment_count": "9",
        "username": "test1",
        "category": "uncategorized",
        "relevancy": "0%",
        "creator_num": "85",
        "type": "Manual",
        "lat": "0.000000",
        "lon": "0.000000",
        "auto_end_date": "0000-00-00",
        "access": "Private",
        "post_image": "http://thepost.com/admin/uploads/thumb/post_default.jpg",
        "post_comments": "9"
    }
}

The push is working when i am only sending this payload:

{
    "aps": {
        "alert": "green commented on your post: 'push post for tim'. Comment is: hey hi!",
        "sound": "default"
    }
}

Any ideas?

The maximum size for a notification payload is 256 bytes. APNS will refuse any notification that exceeds the limit. Your payload is 567 bytes which is why it's you're not seeing the notification go through.
