Node.js 使用 ipaddress 监听 EADDRNOTAVAIL 共享 pc 呼叫

Question

我将 node.js 用于 restAPI 并创建一个应用程序，但为了在本地主机上进行测试，我想使用另一台共享 PC，所以我按照建议添加了一些代码并添加了类似

app.listen(3000, '192.168.100.102', function() { console.log('Listening to port: ' + 3000); });

但是我遇到了这样的错误

我使用默认的 express js 结构使用定义的 here

如果你想展示我的代码，那就是

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');



var routes = require('./routes/index');
var users = require('./routes/users');



var funclib = require('./routes/functions/functionLib');

var moduleNm = 'app.js';
var dbfunction = require('./routes/functions/dbfunction');
var connectDB = dbfunction.connectDB(moduleNm);

var nodeSmtp = require('./routes/functions/nodemailer_smtp');

var mysql = require('mysql');
var connection = require("express-myconnection");

var app = express();

app.set('host', '192.168.100.102');

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));


app.use('/', routes);
app.use('/users', users);



// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handlers

// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
  app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
      message: err.message,
      error: err
    });
  });
}

// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
  res.status(err.status || 500);
  res.render('error', {
    message: err.message,
    error: {}
  });
});


app.listen(3000, '192.168.100.102', function() {
    console.log('Listening to port:  ' + 3000);
});

module.exports = app;

我希望细节足够了。提前致谢

您必须使用分配给该系统上网络接口的有效 IP 地址（或 '0.0.0.0'/'::1' 以侦听 all 接口）。
