Nodejs - Deaktivieren oder Zerstören vhost Subdomains/Proxies

Question

Ich habe den folgenden Code, der dynamisch eine Website zu einer Subdomain proxies.

var app = require('express')(); 
var proxy = require('express-http-proxy'); 
var vhost = require('vhost'); 

app.get('/make', function (req, res) { 
    app.use(vhost('sub1.mysite.com', proxy("www.example.com"); 
    res.send("Proxy Created"); 
}); 

app.get('/destroy', function (req, res) { 

    // Disable or Destroy the subdomain/proxy created above 
    // ??? 

}); 
app.listen(8080); 

Wie würde ich deaktivieren oder zerstören diese neu erstellte Proxy/Sub-Domain von der /destroy Route?

Answer 1

app.js

var Ex = require('express'); 
var app = Ex(); 
app.listen(8080); 

var DomainProxy = require('./DomainProxy').DomainProxy; 
// Pass express instance 'app' into dp, 
// dp will create a vhost router internally 
var dp = new DomainProxy(app); 

var proxies = [ 
    { domain: '1.local', site: 'http://www.bing.com' }, 
    { domain: '2.local', site: 'http://samanthagooden.com' }, 
    { domain: '3.local', site: 'http://www.courtleigh.com' }, 
    { domain: '4.local', site: 'http://example.com' } 
]; 

dp.create(proxies); 

app.get('/make', function (req, res) { 
    var subDomain = 'sub1.mysite.com'; 
    var site = 'http://www.example.com'; // site need to contain 'http://', else dp link rewrite will not work correctly 

    dp.create([{domain:subDomain,site:site}]); 

    res.send("Proxy Created"); 
}); 

app.get('/destroy', function (req, res) { 

    var subDomain = 'sub1.mysite.com'; 

    dp.destroy(subDomain); 

    res.send("Proxy Destroyed"); 

}); 

DomainProxy.js

ich auch von meiner Antwort aufgenommen Nodejs - BrowserSync running on express server

var proxy = require('express-http-proxy'); 
var url = require('url'); 
var vhost = require('vhost'); 
var Ex = require('express'); 

var DomainProxy = (function() { 
    function DomainProxy(app) { // DomainProxy 
     this.list = []; // vhost list array 
     this.router = Ex.Router(); 
     app.use(this.router); 
    } 
    DomainProxy.prototype.create = function (proxies) { 

     proxies.forEach(p => { 

      // Destroy old proxy first 
      this.destroy(p.domain); 

      this.list.push(p.domain); // Add domain into list 

      this.router.use(vhost(p.domain, proxy(p.site, { 
       forwarDomainProxyath: (req, res) => url.parse(req.url).path, 
       intercept: (rsp, data, req, res, callback) => { 
        if (res._headers['content-type']) { 
         var contentType = res._headers['content-type']; 
         // console.log(contentType); 
         if (
          contentType.indexOf('text') !== -1 || 
          contentType.indexOf('javascript') !== -1 
         ) { 
          // Rewrite links 
          var reg = new RegExp(p.site, 'g'); 
          res.send(data.toString().replace(reg, '')); 
         } else { 
          res.send(data); 
         } 
        } else { 
         res.send(data); 
        } 
       } 
      }))); 
     }) 
    }; 
    DomainProxy.prototype.destroy = function (domain) { 
     var i = this.list.indexOf(domain); 
     if (i !== -1) { 
      this.list.splice(i, 1); 
      this.router.stack.splice(i, 1); 
     } 
    }; 
    return DomainProxy; 
}()); 
exports.DomainProxy = DomainProxy;
