Question

我正在使用Twilio Java SDK向我的移动应用发送推送通知。我正在尝试覆盖APN有效负载以设置“徽章”属性，以便在iOS应用程序的图标上显示徽章。使用下面的代码，当我注释掉对来自notificationCreator.setApn的调用时，我成功收到通知，但如果我调用setApn，则不会收到通知。我想我正在创建的APN有效载荷存在问题。这是代码：

NotificationCreator notificationCreator =
    Notification.creator(BuildConfig.TWILIO_NOTIFY_SID)
        .setIdentity(notifyeeId)
        .setBody(body);

// Aps is a POJO class that mirrors the format of a
// notification's APS dictionary.
Aps aps = ApsBuilder.simpleAlertBuilder(body)
              .setBadge(getBadgeCount(notifyeeId))
              .setMutableContent(mutable)
              .build();

// buildApnOverride converts Aps to JSON and returns
// a map mapping "aps" to that JSON.
Map<String, Object> apnOverride = buildApnOverride(aps);
logger.debug(String.format("apnOverride=%s", SharedObjects.getGson().toJson(apnOverride).toString()));
notificationCreator.setApn(apnOverride);

// Some code that I've omitted calls notificationCreator.setData
// to add some custom data.  

Notification notification = notificationCreator.create();
logger.debug(String.format("notification=%s", SharedObjects.getGson().toJson(notification).toString()));

这是日志的输出：

apnOverride=
{
    "aps": "{\"alert\":{\"body\":\"A patient booked a visit with you\"},\"badge\":3,\"sound\":\"default\",\"mutable-content\":1}"
}
notification=
{
    "sid": "XXX",
    "accountSid": "XXX",
    "serviceSid": "XXX",
    "dateCreated": {
        "iMillis": 1517854346000,
        "iChronology": {
            "iBase": {
                "iMinDaysInFirstWeek": 4
            }
        }
    },
    "identities": [
        "XXX"
    ],
    "tags": [],
    "segments": [],
    "priority": "HIGH",
    "ttl": 2419200,
    "body": "A patient booked a visit with you",
    "data": {
        "com.doctheapp.notificationData": "{\"type\":\"APPOINTMENT_BOOKED\",\"attributes\":[\"REFRESH_ACTIVITY_FEED\",\"REFRESH_DOCTOR_SCHEDULE\"],\"additionalData\":\"{\\\"appointmentStartTime\\\":\\\"2018-02-05T19:45Z\\\",\\\"serviceName\\\":\\\"New Patient Visit\\\"}\"}"
    },
    "apn": {
        "aps": "{\"alert\":{\"body\":\"A patient booked a visit with you\"},\"badge\":3,\"sound\":\"default\",\"mutable-content\":1}"
    }
}

任何人都知道我做错了什么？

编辑：我尝试在这里复制粘贴Twilio的示例代码（https://www.twilio.com/docs/api/notify/rest/notifications?code-sample=code-send-a-detailed-notification&code-language=java&code-sdk-version=7.x），我遇到了同样的问题。只有在我注释掉对setApn的调用时才会收到通知。

Twilio开发者传道者在这里。

我看到你试图用这个覆盖APNs通知（为便于阅读而分解）：

{
  "aps": "{
    \"alert\":{
      \"body\":\"A patient booked a visit with you\"
    },
    \"badge\":3,
    \"sound\":\"default\",
    \"mutable-content\":1
  }"
}

当您使用mutable-content时，我查看了文档并在modifying and presenting notifications上找到了此页面。它说：

为远程通知创建有效负载时，服务器应执行以下操作：


包含值为1的mutable-content键。

包含一个警报字典，其中包含警报标题和正文的子项。

我注意到您的通知只包含一个正文。你也可以尝试设置标题吗？

让我知道这是否有帮助

当覆盖apn有效负载时，未收到Twilio通知
