问题描述
我已经开始研究电容器。阅读https://capacitorjs.com/docs/cordova/known-incompatible-plugins后,我发现电容不支持某些cordova插件。
我在我的应用中使用 cordova-plugin-fcm-with-dependecy-updated for android 和 cordova-plugin-fcm for iOS 在我的应用程序中推送通知但电容器不支持这些插件,所以我使用了 https://capacitorjs.com/docs/apis/push-notifications#addlistener 中指导的电容原生方法。
本机方法不会引发任何错误,我也可以获得注册令牌,但我没有在注册设备上收到推送通知。
我也试过 https://www.npmjs.com/package/capacitor-fcm,但 fcm.getToken()
返回 null。
capacitor.config.json
"plugins": {
"PushNotifications": {
"presentationoptions": [
"badge","sound","alert"
]
}
}
app.ts
@Component({
selector: 'app-root',templateUrl: 'app.component.html'
})
export class AppComponent implements OnInit {
constructor(
private platform: Platform,private splashScreen: SplashScreen,private fcmService: FcmService
) {
this.initializeApp();
}
ngOnInit() {}
initializeApp() {
this.platform.ready().then(() => {
setTimeout(() => {
this.splashScreen.hide();
},300);
this.fcmService.initPush();
});
}
}
fcm.service.ts
import { Injectable } from '@angular/core';
import {
Plugins,PushNotification,PushNotificationToken,PushNotificationActionPerformed,Capacitor
} from '@capacitor/core';
import { Router } from '@angular/router';
const { PushNotifications,Modals } = Plugins;
import { FCM } from '@capacitor-community/fcm';
const fcm = new FCM();
const { FCMPlugin } = Plugins;
@Injectable({
providedIn: 'root'
})
export class FcmService {
constructor(
private router: Router) { }
initPush() {
alert('Capacitor platform' + Capacitor.platform);
if (Capacitor.platform !== 'web') {
this.registerPush();
}
}
private registerPush() {
PushNotifications.requestPermission().then((permission) => {
if (permission.granted) {
// Register with Apple / Google to receive push via APNS/FCM
PushNotifications.register();
} else {
alert('No permission for push granted');
}
});
PushNotifications.addListener(
'registration',(token: PushNotificationToken) => {
alert('APN token: ' + JSON.stringify(token));
fcm.getToken().then((r) => {
alert(`FCM Token: ${r.token}`); //---- showing null.
}).catch((err) => {
alert(`FCM Token ERROR: ${JSON.stringify(err)}`);
});
}
);
PushNotifications.addListener('registrationError',(error: any) => {
alert('Registration Error: ' + JSON.stringify(error));
});
PushNotifications.addListener(
'pushNotificationReceived',async (notification: PushNotification) => {
Modals.alert({
title: notification.title,message: notification.body
})
}
);
PushNotifications.addListener(
'pushNotificationActionPerformed',async (notification: PushNotificationActionPerformed) => {
alert('Action performed: ' + JSON.stringify(notification.notification));
}
);
}
}
解决方法
您在 Firebase 项目中添加了 SHA certificate fingerprints
并更新了 google 服务文件?
