create httpserver using node.js

Question

iam new to node.js am trying to creating a http server and spawn a child process.

see the code

var server = http.createServer(function(req, res) {
res.writeHead(200);
  switch(req.url) {

        case '/vm/start':
            req.on('data', function(data) {             
            console.log("hello");
                console.log(data.toString());
                exec('CALin.exe', function(err, data) {     
                    console.log(err)
                    console.log(data.toString());


});
                    res.end('');
                });
            });

            break;
    }
});

server.listen(9090);
console.log("Server running on the port 9090");

Remove the exec call and see if that works. For me it doesn't reset connection without it. — Himanshu

There is no data being sent in the request so the data event does not get triggered and therefore res.end never gets called and the request times out. Add a listener for the requests end event and then call response.end.

Write your code in a js file and run it

var http = require("http");
var server = http.createServer(function(request, response) {
response.writeHead(200, {"Content-Type": "text/html"});
response.write("<!DOCTYPE "html">");
response.write("<html>");
response.write("<head>");
response.write("<title>Hello World Page</title>");
response.write("</head>");
response.write("<body>");
response.write("Hello World!");
response.write("</body>");
response.write("</html>");
response.end();
});

server.listen(9090);
console.log("Server is listening");

Run this code as

 node web_server.js
