I am trying to get header of get request.
But i receive the error:

TypeError: request.getHeader is not a function

    at Server.<anonymous> (/home/pi/progs/smarthome/Site/cpu.js:8:27)

    at Server.emit (events.js:198:13)

    at parserOnIncoming (_http_server.js:695:12)

    at HTTPParser.parserOnHeadersComplete (_http_common.js:111:17)

here is my code:

var http = require("http");

var fs =  require("fs");



var server = http.createServer(function(request, response) {



    var temp = fs.readFileSync("/sys/class/thermal/thermal_zone0/temp");

    var temp_c = temp/1000;



    var header = request.getHeader('Content-Type');

    console.log(header);



    response.writeHead(200, {"Content-Type": "text/plain"});

    response.write("Raspberry Pi cpu temperature: ");

    response.write("n" + temp);

    response.write("n" + temp_c);

    response.end();

});

server.listen(8080);

What am I doing wrong?
