Question

我已经使用Firebase设置了推送通知，并且无法发送自定义数据。

我也尝试过PyFCM库，但是数据仍然为空。根据我发现的情况，payload requires encryption但我不确定如何实现。

如何在python中加密推送数据或通过推送通知发送自定义数据？

我希望将event_handler.py作为服务运行，轮询MySQL数据库以获取新通知，并向该用户发送推送通知。

我已经保存了用户的registration_id，我只需要能够通过推送通知发送数据。

service-worker.js

 self.addEventListener('push', function(event) {
  if (event.data) {
    console.log(event.data.text());
  }
  console.log('Received a push message', event);

  if (event.title) {
    var title = event.title;
  } else {
    var title = 'New message.';
  }

  var body = 'You have received a push message.';
  var icon = 'img/logo.png';
  var tag = 'simple-push-demo-notification-tag';

  event.waitUntil(
    self.registration.showNotification(title, {
      body: body,
      icon: icon,
      tag: tag,
    })
  );
});

我可以使用以下方式发送推送通知：

notification_handler.py

import requests

headers = {
    'Content-type': 'application/json',
    'Authorization': 'key=AAAAl...',
}

data="""{
   "to" : "fk1jL...",
   "data" : {
     "title" : "hi there",
     "body" : "new push message",
   },
 }"""


response = requests.post('https://fcm.googleapis.com/fcm/send', headers=headers, data = data)

但是，当接收到推送通知时，控制台输出中的数据为空：

Received a push message  PushEvent {isTrusted: true, data: null, type: "push", target: ServiceWorkerGlobalScope, currentTarget: ServiceWorkerGlobalScope, …} bubbles: false cancelBubble: false cancelable: false composed: false currentTarget: ServiceWorkerGlobalScope {clients: Clients, registration: ServiceWorkerRegistration, onactivate: null, onfetch: null, oninstall: null, …} data: null defaultPrevented: false eventPhase: 0 isTrusted: true path: [] returnValue: true srcElement: ServiceWorkerGlobalScope {clients: Clients, registration: ServiceWorkerRegistration, onactivate: null, onfetch: null, oninstall: null, …} target: ServiceWorkerGlobalScope {clients: Clients, registration: ServiceWorkerRegistration, onactivate: null, onfetch: null, oninstall: null, …} timeStamp: 0 type: "push"
__proto__: PushEvent

推送通知PushEvent数据为null
