如何在向WEB用户发送FCM通知时设置ttl (生存时间)？

const admin = require("firebase-admin");

// 初始化FCM
admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://<DATABASE_NAME>.firebaseio.com"
});

// 创建消息
const message = {
  notification: {
    title: "Notification Title",
    body: "Notification Body"
  },
  token: "<DEVICE_TOKEN>",
  android: {
    ttl: "<TTL_IN_SECONDS>s" // 设置ttl
  }
};

// 发送通知
admin.messaging().send(message)
  .then((response) => {
    console.log("Successfully sent message:", response);
  })
  .catch((error) => {
    console.log("Error sending message:", error);
  });

const app = tcb.init({
  env: "your-environment-id"
});

// 发送通知
app.messaging().send({
  data: {
    title: "Notification Title",
    body: "Notification Body"
  },
  token: "<DEVICE_TOKEN>",
  android: {
    ttl: "<TTL_IN_SECONDS>s" // 设置ttl
  }
})
  .then((response) => {
    console.log("Successfully sent message:", response);
  })
  .catch((error) => {
    console.log("Error sending message:", error);
  });
