我正在使用aws-amplify库https://aws-amplify.github.io/docs/js/push-notifications开发一个react native应用。单击推送通知时，我的应用应重定向到通知屏幕。当我从以下位置打开应用时，我没有导航道具通知，因此我可以在没有道具https://reactnavigation.org/docs/en/navigating-without-navigation-prop.html的情况下使用它，但是仍然出现此错误“未定义不是对象（正在评估't.dispatch'）”。我在我的应用中使用了react-navigation
import PushNotification from '@aws-amplify/pushnotification';
import NotificationList from './NotificationList';
import NavigationService from './NavigationService';
Analytics.configure(awsmobile);
PushNotification.configure(awsmobile);
if(Platform.OS === 'android'){
PushNotification.onNotification((notification) => {
// console.log('in app notification : Outside App', notification);
Auth.currentAuthenticatedUser({
bypassCache: false // Optional, By default is false. If set to true, this call will send a request to Cognito to get the latest user data
}).then(user => {
console.log('Current user : Outside App', user.attributes.sub)
const currentDate = new Date();
const todayDate = moment(currentDate).format("YYYY-MM-DD")
var todayTime = moment().format('HH:mm:ss')
const notificationDetails = {
userId: user.attributes.sub,
userTitle: notification.title,
userBody: notification.body,
userDate: todayDate,
userTime: todayTime,
};
console.log("notificationDetails outside", notificationDetails)
API.graphql(graphqlOperation(createUserNotification, { input: notificationDetails }))
.then(response => {
console.log(JSON.stringify(response, null, 2));
})
.catch(err => {
console.log('Error Saving Details...', err);
this.setState({ showActivityIndicator: false });
});
});
});
PushNotification.onNotificationOpened((notification) => {
const b = new Home();
console.log('onNotificationOpened 1');
b._handleNotificationOpen(notification)
});
}
class Home extends React.Component {
constructor(props) {
super(props);
global.ShowRecordVar = "12"
this._handleNotificationOpen =
this._handleNotificationOpen.bind(this);
this.state = {
apiResponse: 0,
loading: true,
}
}
_handleNotificationOpen = (notification) => {
if (notification["pinpoint.deeplink"]) {
NavigationService.navigate('NotificationList',{notification});
}
}
