simple ajax request to localhost nodejs server

Question

I wrote very simple server :

/* Creating server */
var server = http.createServer(function (request, response) {
  response.writeHead(200, {\"Content-Type\":         


        

Answer 1

The first error is caused by CORS (Cross Origin Resource Sharing) policy. It's rule by all browsers that you cannot make a request to a remote server in AJAX other than to the current server the script/page was loaded from unless that remote server allows it via Access-Control-Allow-Origin header.

I suggest serving the page from the same Node.js server. Then it will work. Example, when the request comes to root / page, then serve the index.html file, otherwise, server whatever other content you want.

var http = require('http'),
    fs = require('fs');

/* Creating server */
var server = http.createServer(function (request, response) {
    if (request.url == '/' || request.url == '/index.html') {
        var fileStream = fs.createReadStream('./index.html');

        fileStream.pipe(response);
    } else {
        response.writeHead(200, {"Content-Type": "text/plain"});
        response.end("Hello World\n");
    }
});

/*Start listening*/
server.listen(8000);
