javascript - Node.js 服务器延迟

Question

您将如何在下面的两个发射之间引入延迟:

var app = require('http').createServer();
var io = require('socket.io')(app);

app.listen(8092);

io.on('connection', function (socket) {  
    socket.emit('foo', ["data1"]);
    socket.emit('foo', ["data2"]);
});

我想创建一个简单的服务器模拟器，它在不同时间点输出数据。

Answer 1

你尝试过这个吗:

var app = require('http').createServer();
var io = require('socket.io')(app);

app.listen(8092);

io.on('connection', function(socket) {

  socket.emit('foo', ["data1"]);

  setTimeout(() => {
    socket.emit('foo', ["data2"]);
  }, 1500); // change the 1500 to whatever time delay you want in milliseconds
});
