问题描述
在运行这个简单的 ping 测试时,我遇到了 25 秒的持续延迟.服务器没有记录 ping 事件,但我假设它正在接收它,因为客户端正在收到回复.有关如何解决此问题的任何想法?
I am experiencing consistent delay of 25 seconds when running this simple ping test. The server is not logging the ping event but I am assuming it is receiving it because the client is getting a reply. Any ideas on how to fix this?
客户
var io = require('socket.io-client')('http://68.12.157.176:3000')
var ping_time = Date.now();
function ping(){
ping_time = Date.now();
console.log('sending ping...');
io.emit('ping');
}
ping();
io.on('pong', function (data) {
ping_time = Date.now() - ping_time;
console.log("replied in " + ping_time + "ms");
ping();
});

服务器
var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('../..')(server);
var port = process.env.PORT || 3000;
server.listen(port, function () {
console.log('Server listening at port %d', port);
});
io.on('connection', function (socket) {
console.log('client connected');
socket.on('ping', function (data) {
console.log("received ping, sending reply"); //no log shown???
socket.emit('pong'); //client receives event ~25 seconds after request
});
});
服务器日志
Server listening at port 3000
client connected
推荐答案
把我的评论变成答案,因为它解决了你的问题:
Making my comment into an answer since it solved your problem:
Socket.io 使用 ping
和 pong
作为实现内部的消息名称.更改为不同的消息名称.
Socket.io is using ping
and pong
as message names itself internal to the implementation. Change to different message names.
