Question

关闭应用程序后通知不起作用

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的？并且通知不起作用，应用程序既不在后台也没有在前台关闭，为什么？

Answer 1

尝试这种方式..

如果令牌位于数组中并将信息传递到数据对象中，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");
    }
  });
});

有两种选择：

选项 1：这是一个用户（一个设备令牌）。

var message = {

   to: token,

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

  };

结果：

成功 JSON

选项 2：这适用于多个用户（多个设备令牌）..

     var message = {

   registration_ids: token,

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

  };

结果：

成功 JSON

注意：创建通知数据只有一处不同。使用 registration_ids 而不是 to。
