node.js 끄적

node.js 웹서버 구동

var http = require('http');
var fs = require('fs');
var app = http.createServer(function (request, response) {
    var url = request.url;
    if (request.url == '/') {
        url = '/index.html';
    }
    if (request.url == '/favicon.ico') {
        response.writeHead(404);
        response.end();
        return;
    }
    response.writeHead(200);
    response.end(fs.readFileSync(__dirname + url));

});
app.listen(3000);

url로 입력된 값 사용

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

var app = http.createServer(function (request, response) {
    var _url = request.url;
    var queryData = url.parse(_url, true).query;
    console.log(queryData.id); // localhost:300/?ID=HTML에서 HTML
    if (_url == '/') {
        _url = '/index.html';
    }
    if (_url == '/favicon.ico') {
        return response.writeHead(404);
    }
    response.writeHead(200);
    response.end(queryData.id);

});
app.listen(3000);

?id= 에 따른 결과

$(queryData.id)

루트로 접속할때

if (_url == '/') { // home root
        title = 'Welcome';
    }
