这是个新手，所以这可能是一个愚蠢的问题。测试 Node.js 服务器和 socket.io。试图找出常数是什么
request /inform
发送到我的服务器的请求是。
这是浏览器的问题吗？ socket 的事？据我所知，我并没有在我的网站上要求它......
更新:在服务器和客户端上禁用了 socket.io，并且请求仍在到来。
谢谢!
即使浏览器关闭，请求也会继续出现。更改端口会停止请求...
这是服务器(更多的是学习体验，而不是为生产做好准备)以及之后完整记录的请求。
//EXAMPLE server without any outside frameworks ie. "Express"
//Require modules
var http = require('http'); //heart of node, handles http requests and responses
var fs = require('fs'); //read and write to file system
var path = require('path'); // used to extract extension from url path
var server = http.createServer(function (request, response) { //creating the server
console.log('request ', request.url); //logs the requested url
var filePath = './public' + request.url; // adds default path plus requested path
if (filePath == './public/')
filePath = './public/index.html'; //if path is left blank, returns homepage
//The HTTP 'Content Type' header field must be correct to return css, image, and other static files
//the following takes care of that
var extname = String(path.extname(filePath)).toLowerCase(); //extract extension convert to lower case string
var contentType = 'text/html'; //default contentType to be sent back
var mimeTypes = { //maps extention to type

};
contentType = mimeTypes[extname] || 'application/octet-stream'; //set contentType to corresponding value
//Content Type is now defined based on request
//Now we serve the file
fs.readFile(filePath, function(error, content) { //invokes fs module to read file at filepath

嗯，它来 self 的本地网络...周围有几个 UniFi aps，显然它们正在广播和轮询
