如何使用相同的有效负载发送丰富的（图像/数据）通知iOS和Android

Question

示例：

有效载荷：

{
    "to": "topics/myTopic",
    "content_available": true,
    "mutable_content": true,
    "priority": "high",
    "notification": {
        "title": "Happy Alert",
        "body": "We have some special offers available for you!",
        "attachment-url": "https://hello.scene7.com/is/image/officedepot/676092_p_1?$OD%2DMed$",
        "media_type": "image",
        "adUrl": "/coupon/XXXX",
        "intent": "tested",
        "sound": "default"
    },
    "data": {
        "title": "Happy Alert",
        "body": "We have some special offers available for you!",
        "attachment-url": "https://hello.scene7.com/is/image/officedepot/676092_p_1?$OD%2DMed$",
        "media_type": "image",
        "adUrl": "/coupon/XXXX",
        "intent": "tested",
        "sound": "default"
    }
}

我想使用相同的有效负载为iOS和Android发送通知。但是到目前为止，它不能正常工作。
