在 Unity 上使用 OneSignal 向特定用户发送通知时出错

Question

尝试向特定用户发送通知时，会生成错误。我不明白发生了什么，因为我正在关注文档。

测试是在 Android 设备上完成的。

发送通知的代码：

public static void SendNotification(string title, string message, string senderId){
    extraMessage = "Waiting to get a OneSignal userId. Uncomment OneSignal.SetLogLevel in the Start method if it hangs here to debug the issue.";
    Debug.Log($"OneSignalExtra: {extraMessage}");
    OneSignal.IdsAvailable((userId, pushToken) => {
        if (pushToken != null) {
            var userIdNotify = senderId;

            var notification = new Dictionary<string, object>();
            notification["contents"] = new Dictionary<string, string>() { {"pt", title} };
            notification["headings"] = new Dictionary<string, string>() { {"pt", message} };
            notification["template_id"] = "my template id";
            // Send notification to this device.
            notification["include_player_ids"] = new List<string>() { userIdNotify };
            OneSignal.PostNotification(notification, (responseSuccess) => {
                extraMessage = "Notification posted successful! Delayed by about 30 secounds to give you time to press the home button to see a notification vs an in-app alert.\n" + Json.Serialize(responseSuccess);
                Debug.Log($"OneSignalExtra: {extraMessage}");
            }, (responseFailure) => {
                extraMessage = "Notification failed to post:\n" + Json.Serialize(responseFailure);
                Debug.Log($"OneSignalExtra: {extraMessage}");
            });
        } else {
            extraMessage = "ERROR: Device is not registered.";
        }
        print(extraMessage);
    }

    );
}

尝试发送后出现错误：

12-09 14:18:25.493: E/Unity(28828): Exception Exception: NullReferenceException: 未将对象引用设置为对象的实例 12-09 14:18:25.493: E/Unity(28828): OneSignal.isValidSuccessFailureDelegate (System.Collections.Generic.Dictionary2[TKey,TValue] jsonObject) (at <6d52692b70b2475ca1c61c8ae70ef58a>:0) 12-09 14:18:25.493: E/Unity(28828): OneSignal.onPostNotificationFailed (System.String jsonString) (at <6d52692b70b2475ca1c61c8ae70ef58a>:0) 12-09 14:18:25.493: E/Unity(28828): 12-09 14:18:25.493: E/Unity(28828): (Filename: ./Runtime/Export/Debug/Debug.bindings.h Line: 35) 12-09 14:18:25.502: E/Unity(28828): NullReferenceException: Object reference not set to an instance of an object 12-09 14:18:25.502: E/Unity(28828): at OneSignal.isValidSuccessFailureDelegate (System.Collections.Generic.Dictionary2[TKey,TValue] jsonObject) [0x00026] in <6d52692b70b2475ca1c61c8ae70ef58a >:0 12-09 14:18:25.502: E/Unity(28828): 在 OneSignal.onPostNotificationFailed (System.String jsonString) [0x00015] 在 <6d52692b70b2475ca1c61c8ae70ef58a>:0 12-09 14:18:25.502: E/Unity(28828):

我知道错误发生在 OneSignal.PostNotification。

OneSignal 似乎需要一个字段，我用英文说标题和消息。在我的情况下，它是英语和葡萄牙语，只是把它作为葡萄牙语会让我出错。

在 OneSignal 中创建的模板也有英语和葡萄牙语版本。

代码如下所示：

public static void SendNotification(string title, string message, string senderId){
extraMessage = "Waiting to get a OneSignal userId. Uncomment OneSignal.SetLogLevel in the Start method if it hangs here to debug the issue.";
OneSignal.IdsAvailable((userId, pushToken) => {
    if (pushToken != null) {
        var userIdNotify = senderId;

        var notification = new Dictionary<string, object>();
        notification["headings"] = new Dictionary<string, string>() { {"pt", title}, { "en", title } };
        notification["contents"] = new Dictionary<string, string>() { {"pt", message}, { "en", message } };
        notification["include_player_ids"] = new List<string>() { userIdNotify };
        
        notification["template_id"] = "my code template";
        
        // Send notification to this device.
        
        OneSignal.PostNotification(notification, (responseSuccess) => {
            extraMessage = "Notification posted successful! Delayed by about 30 secounds to give you time to press the home button to see a notification vs an in-app alert.\n" + Json.Serialize(responseSuccess);
        }, (responseFailure) => {
            extraMessage = "Notification failed to post:\n" + Json.Serialize(responseFailure);
        });
    } else {
        extraMessage = "ERROR: Device is not registered.";
    }
    print(extraMessage);
}

);

}
