socket.io的节点服务器找不到本地主机

Question

I have following code in my server.js file

var mongo  = require('mongodb').MongoClient,
    client = require('socket.io').listen(8080).sockets;

When I execute node server.js then it does not show anything on terminal. When I type http://localhost:8080 in browser then in browser console I get Failed to load resource: the server responded with a status of 404 (Not Found)

Why and how can I fix this problem?

Answer 1

The service is running on port 8080, but there is no resource for the service to return/load hence the 404. I replicated your error just to see if there was something I was missing. If there was nothing running on port 8080 you would get something like Webpage unavailable . Try looking through the docs and giving the server something to return. You stated yourself that the entire code works, so go from there. Those two lines alone are not going to serve anything on their own.
