我是一个初学者express.js,我试图理解之间的差异res.send和res.write？

我试图发送一个整数,response.send()但我一直收到这个错误

express deprecated res.send(status):改为使用res.sendStatus(status)

我没有发送状态,我的代码是

app.get('/runSyncTest' , function(request, response){  

var nodes = request.query.nodes;
var edges = request.query.edges;
if (edges == "" ){
    edges = []
}

userStory.userStory(nodes,edges);
connection.query('SELECT MAX(id) as id FROM report ', function(err,results, fields) {
                idTest = results[0].id
                response.send (idTest)
});

});

当数据被推送到数据库时，我会使用数据流自动更新我的角度材料数据表

这是我的 router.js

router
  .route("/")
  .get(function (req, res, err) {

    // Get a database reference to our posts
    var db = admin.database();
    var ref = db.ref("/");

    // Attach an asynchronous callback to read the data at our posts reference
    ref.on("value", function (snapshot) {
      var list = [];
      snapshot.forEach(function (elem) {
        list.push(elem.val());
      })


      res.send(list);

    }, function (errorObject) {
      console.log("The read failed: " + errorObject.code);
    });
  });

router
  .route("/")
  .post(function (req, res, err) {
    console.log(req.body);
    // Get a database reference to our …
