Node.js + Socket.io：尝试使用套接字反垃圾邮件模块时，出现EADDRINUSE错误

Question

我正在尝试在Web应用程序中使用socket-anti-spam模块（https://github.com/michaeldegroot/socket-anti-spam）。但是，当我尝试使用它时，出现以下错误：

错误：听EADDRINUSE ::: 3000

下面是我的代码：

var express = require("express");
var socket = require("socket.io");
var socketListen = socket.listen(3000);

var bodyParser = require('body-parser');
var cors = require('cors');
var SocketAntiSpam = require("socket-anti-spam");

require('dotenv').config({ path: 'variable.env' });

// Initialize Node.JS application
var app = express();
var server = app.listen(process.env.PORT || 3000);
app.use(express.static("public", {
    dotfiles: 'allow'
}));
app.use(cors());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

const socketAntiSpam = new SocketAntiSpam({
    banTime:            30,         // Ban time in minutes
    kickThreshold:      2,          // User gets kicked after this many spam score
    kickTimesBeforeBan: 1,          // User gets banned after this many kicks
    banning:            true,       // Uses temp IP banning after kickTimesBeforeBan
    io:                 socketListen,  // Bind the socket.io variable
});

您尝试在同一端口（3000）上侦听两次，这就是为什么您收到“地址使用中”错误的原因。

尝试类似的东西：

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);

server.listen(80);
