当我的应用程序处于后台/关闭时,我可以获得推送通知,当我点击它并打开时,我可以在通知的有效负载中获取数据
"notification": {
"title": "Chat Messages",
"body": `You have received chat messages from ${userName}`,
"sound": "default",
"click_action":"FCM_PLUGIN_ACTIVITY",
"icon":"fcm_push_icon"
},
"data": {
"user_id" : from_user_id,
"user_name" : userName,
"type" : notification_type
}
但有一个问题是我在后台/关闭时点按通知后无法打开特定页面。
以下是app.components.ts中的代码:
import { Component, ViewChild } from '@angular/core';
import { Platform, NavController } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { FCM } from '@ionic-native/fcm';
import { LoginPage } from '../pages/login/login';
import { TestpagePage } from '../pages/testpage/testpage';
@Component({
templateUrl: 'app.html'
})
export class MyApp {
@ViewChild('myNav') navCtrl: NavController
rootPage:any = LoginPage;
constructor(fcm: FCM, platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
platform.ready().then(() => {
// Okay, so the platform is ready and our plugins are available.
// Here you can do any higher level native things you might need.
statusBar.styleDefault();
splashScreen.hide();
fcm.onNotification().subscribe(function(data) {
if(data.wasTapped) {
alert('HI');
if(data.type == 'messages') {
alert('HEY');
this.navCtrl.setRoot(TestpagePage);
}
} else {
alert('Untapped<br>' +
'User ID: ' + data.user_id +
'<br>User Name: ' + data.user_name +
'<br>Type: ' + data.type);
}
});
});
}
}
它将在if(data.wasTapped) {
内执行'HI'和'HEY'警报,但似乎this.navCtrl.setRoot('TestpagePage');
未被触发。我不知道为什么请帮助我!

所以问题已经解决了。
像@SurajRao建议的那样,我没有使用<input id="btn-Preview-Image" type="button" value="Preview"/>
<div id="previewImage"></div>
<a id="btn-Convert-Html2Image" href="#">Download</a>
,而是遵循了他的建议,并将我的代码更新为fcm.onNotification().subscribe(function(data) {
,并且确实有效。
