Listen to a different IP address

问题

This is my code:

var server = express();

// Create the HTTP server
http
    .createServer(server)
    .listen(80, '10.10.10.10');

Once the server has been started, how can I dynamically change the listened IP address, say to 11.11.11.11 instead of 10.10.10.10. Is there an "unlisten" method?

回答1:

you have to use server.close() not app.close()..

var express = require('express')
  , http = require('http')
  , app = express()
  , server = http.createServer(app)

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

server.listen(8000,'127.0.0.1',function(){
 server.close(function(){
   server.listen(8001,'192.168.0.202')
 })
})

should work

I think the "unlisten" function you're looking for is called "close": http://nodejs.org/api/http.html#http_server_close_callback

回答3:

What your are trying to accomplish is quite non-standard in my opinion. I would suggest server.close(). Close will wait all request to finish and trigger the "close" event. You can bind on that event to listen on the new IP. This is quite weird tho.

回答4:

app.listen(3000,'0.0.0.0',function(){
  console.log('Server running at http://127.0.1.1:8000/')
})

will work with express
