iOS推送通知：發送此有效負載時未獲得任何推送

Question

當我嘗試發送以下有效載荷以在iPhone上生成推送通知時，我收到一條成功消息，但沒有收到任何推送通知。

我想知道此有效載荷是否為有效格式？

{
    "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"
    }
}

當我僅發送此有效負載時，推送有效：

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

有任何想法嗎？

通知有效負載的最大大小為256個字節。 APNS將拒絕任何超出限制的通知。 您的有效載荷為567字節，這就是為什么您沒有看到通知通過的原因。
