节点 server.js 没有响应

Question

I'm pretty new to node and I'm trying to create a simple server for my website but when I type in node server.js in command prompt nothing happens.

var http = require("http");  
http.createServer(function(request, response) {
       response.writeHead(200, {"Content-Type": "text/plain"});
       response.write("It's alive!");
       response.end();
}).listen(3000);

This is what I see when I try to run my server.js file:

I'm fairly certain my code is right, is there anything else I'm doing wrong?

Answer 1

The server is working just fine. You need to visit http://localhost:3000/ from your browser to view the expected output ("It's alive!").

To write messages to the console, use console.log() .

Answer 2

The console output you show seems correct given your code.

Did you open a webbrowser and try opening http://localhost:3000 ?

If you want to see some console output to confirm your server started up, try adding this at the end of your server.js file:

console.log('Server running at http://localhost:3000');

Answer 3

You only need to hit the URL http://localhost:3000 .

The server is already started after you hit the command "node server.js" and you will get the output - " It's alive! " because of this line present in your code: response.write("It's alive!");

Answer 4

First time starting up node server made a very small mistake of not calling "response.end" as a function that made the server not response and take very long to load. Should have been response.end()

const server = http.createServer(function(request, response){
response.writeHead(200,{'Content-Type': 'text/html'})
response.write('Hello Node')
response.end 
})
