如何使用 node-fcm 向多个设备发送通知

Question

应用关闭时通知不起作用

const 令牌 = ["AAASDfsadfasdfaFDSDFSDLFJLSDAJF;DSJFAsdfdsfsdf"];

app.get('/send-notfication', (req, res) => {
        
        var FCM = require('fcm-node');
        var fcm = new FCM(serverKey);
     
        var messageToSend = "Hi there this is message";

        var message = {
         to: token,

         data: {
           ar_message: messageToSend,
         },
        };
        
        fcm.send(message, function(err, response){
            if (err) {
                console.log("Something has gone wrong!", err);
            } else {
                console.log("Successfully sent with response: ", response.results);
                res.send("Successfully sent")
            }
        });
    })

问题是如何在其中设置通知标题？并且通知不起作用应用程序既不在后台也不在前台关闭为什么？

试试这个方法..

如果标记在数组中并将信息传递到数据对象，请使用“registration_ids”而不是“to”。

app.get("/send-fcm-notification", (req, res) => {
  var FCM = require("fcm-node");
  var fcm = new FCM(serverKey);
  var message = {

   registration_ids: token,

    data: {
      title: "Hi there this is title",
      message: "Hi there this is message"
    },

  };

  fcm.send(message, function (err, response) {
    if (err) {
      console.log("Something has gone wrong!", err);
    } else {
      console.log("Successfully sent with response: ", response.results);
      res.send("Successfully sent");
    }
  });
});
