【问题描述】：

1 年前，我在我的 react-native 应用程序中成功获得了 pushToken。但是现在官网示例代码已经改了，所以找不到pushToken的获取方法。

这是我去年使用的代码。（类组件）

constructor(props) {
    super(props);
    ...
    OneSignal.addEventListener('ids', this.onIds);
}
componentWillUnmount() {
    OneSignal.removeEventListener('received', this.onReceived);
    OneSignal.removeEventListener('opened', this.onOpened);
    OneSignal.removeEventListener('ids', this.onIds);
}
onIds(device) {
    console.log('Device info: ', device);  // I got pushToken here successfully last year.
}

这是我当前的代码。（功能组件）

useEffect(() => {
    // OneSignal Init Code
    OneSignal.setAppId("My-OneSignal-Key");
    OneSignal.setLogLevel(6, 0);
    // END OneSignal Init Code

    // Prompt for push on iOS
    OneSignal.promptForPushNotificationsWithUserResponse(response => {
        console.log("Prompt response:", response);
    });

    // Method for handling notifications received while app in foreground
    OneSignal.setNotificationWillShowInForegroundHandler(notificationReceivedEvent => {
        console.log("OneSignal: notification will show in foreground:", notificationReceivedEvent);
        let notification = notificationReceivedEvent.getNotification();
        console.log("notification: ", notification);
        const data = notification.additionalData
        console.log("additionalData: ", data);
        // Complete with null means don't show a notification.
        notificationReceivedEvent.complete(notification);
    });

    // Method for handling notifications opened
    OneSignal.setNotificationOpenedHandler(notification => {
        console.log("OneSignal: notification opened:", notification);
    });
}

但是现在，我应该从哪里获得 pushToken？

【解决方案1】：

我在the doc找到这个：

const deviceState = await OneSignal.getDeviceState();

所以我认为它可能是这样的：

const deviceState = (await OneSignal.getDeviceState()).pushToken;

【解决方案2】：

查看setNotificationOpenedHandler或setNotificationWillShowInForegroundHandler的通知对象内部。
