如果在我打开通知之前关闭了应用程序，则不会处理HandleNotificationOpened [英] HandleNotificationOpened are not handled if app is closed before i open the notification

问题描述

如果App在后台运行或正在运行，HandleNotificationOpened可以正常工作，但是如果我在应用关闭时打开通知，则不会触发.

HandleNotificationOpened is working perfectly if App is on the background or running but it's not fired if i open the notification when app is closed.

我已尝试通过SecureStorage保留事件中的数据，因为我不确定事件是否在正确的时间运行，或者是否在错误的时间运行.

I've tried to persist the data from event with SecureStorage, because i'm not sure if the event run but in the wrong time or it doesn't run at all.

public App()
{
    OneSignal.Current.StartInit("onesignal-id").HandleNotificationOpened(HandleNotificationOpened).HandleNotificationReceived(HandleNotificationReceived).EndInit();
}


private async void HandleNotificationOpened(OSNotificationOpenedResult result)
{
    var data = result.notification.payload.additionalData;

    if (data != null)
    {
        data.TryGetValue("Title", out object Title);
        data.TryGetValue("Conteudo", out object Conteudo);
        data.TryGetValue("Link", out object RLink);
        string lastvar = (Title.ToString().GetHashCode() + Conteudo.ToString().GetHashCode() + RLink.ToString().GetHashCode()).ToString();

        if (!ChecarDB(lastvar))
        {
            InserirDB(Title.ToString(), Conteudo.ToString(), RLink.ToString());
        }

        await SecureStorage.SetAsync("UrlFromPush", RLink.ToString());
        var page = new MainPage();
        MessagingCenter.Send<MainPage>(page, "MudarURL");
    }
}

预期结果是应用程序正确处理了事件，根本没有错误消息.

Expected result is the application properly handle the event, No error messages at all.

推荐答案

我已经使用URI方案访问了早期初始化背景数据，使用自定义格式方法将Intent?.Data?.EncodedQuery;的HandleNotificationOpened方法替换为Intent?.Data?.EncodedQuery;，从而解决了此问题我得到了预期的结果.

I've solved this issue using URI Scheme to access early init background data, replacing the HandleNotificationOpened method for Intent?.Data?.EncodedQuery; with custom formatting method, that's how i got the expected result.
