javascript - NodeJs错误v-host中间件

Question

我会用expressjs创建一个虚拟主机。我启动服务器时遇到问题。

这是我的测试代码:

/home/*****/Scrivania/server/server.js

var express = require('express'),
    app = express();

app.use(express.vhost('*.site1.com', require('./apps/appDue')));

app.listen(3000);

/home/****/Scrivania/appDue/index.js

var express = require('express'),
    app = express();

app.get('/', function(req, res) { 
    res.send('Home Page'); 
});

module.exports = app;

这是我启动服务器时的结果:

Error: Most middleware (like vhost) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.

提前感谢您的回答。

它的问题正是错误消息所说的错误:大多数中间件(如虚拟主机)不再与 Express 捆绑在一起，必须单独安装。请参阅 https://github.com/senchalabs/connect#middleware。

您需要将该模块添加到您的package.json中。
