Я не могу получить конкретный URL

Я пытаюсь получить что-то вроде localhost:8080/register/something/something/something

но он продолжает давать URL, как обычно: http://localhost:8080/?uname=Sam&email=12&password=12

моя функция такова:

function register(){
    var uname1 = document.getElementById("uname").value;
    var password1 = document.getElementById("psw").value;
    var email1 = document.getElementById("email").value;

    if ((uname !== "")&&(password !== "")&&(email !== "")) {
        var xhttp = new XMLHttpRequest();
        xhttp.open("GET", "/register/" + uname1 + "/" + password1 + "/" + email1, true);
        xhttp.send();
    }
}

HTML:

<div id = "id02" class = "modal">
        <form class = "modal-content animate">
            <span onclick = "document.getElementById('id02').style.display='none'" class = "close" title = "Close Modal">&times;</span>     <div class = "container2">
                <label for  = "uname"><b>Username</b></label>
                <input type = "text" placeholder = "Enter Username" name = "uname" id = "uname" required>

                <label for = "psw"><b>Email</b></label>
                <input type = "text" placeholder = "Enter Email" name = "email" id = "email" required>

                <label for = "password"><b>Password</b></label>
                <input type = "password" placeholder = "Enter Password" name = "password" id = "psw" required>

                <button class = "button2" type = "submit" onclick = "register();">Register</button>
                <button type = "button" onclick = "document.getElementById('id02').style.display='none'" class = "cancelbtn">Cancel</button>
            </div>
        </form>
    </div>

И мой сервер:

//Import the express and url modules
var express = require('express');
//var url = require('url');

//The express module is a function. When it is executed it returns an app object
var app = express();

app.get('/register/*', regF);


app.use(express.static('website'));

//Start the app listening on port 8080
app.listen(8080);

var uname = "";
var password = "";
var email = "";


//Function that adds test data to database4
//addData("name2","wads" ,"den@3");
function addData(n , p , e  ){

//Import the mysql module
    var mysql = require('mysql');

//Create a connection object with the user details
    var con = mysql.createConnection({
        host: "localhost",
        user: "gus",
        password: "12",
        database: "website"
    });



//Connect to the database
    con.connect(
        //This function is called when the connection is attempted
        function(err) {
            if (err) throw err;//Check for errors

            //Output results
            console.info("Connected!");
            console.info("YEY");

        }
    );

//----------------------------------------------------------------

    //Build SQL query
    var sql = "INSERT INTO customers (name, password, email) " +
        "       VALUES ( '"+  n +  "' , '"+ p +  "'  , '" + e + "' )";

    //Execute the query
    con.query(sql, function (err, result) {

        //Check for errors
        if (err) throw err;

        //Output results
        console.info(result.affectedRows + ' rows updated. ID is ' + result.insertId);

    });
    con.end();
}



function regF(request, response){

    //Split the path of the request into its components
    var pathArray = request.url.split("/");
     email = pathArray[pathArray.length - 1];
     password = pathArray[pathArray.length - 2];
     uname = pathArray[pathArray.length - 3];

    if (uname != "" && password! = "" && email! = ""){
        // addData("name3","wads" ,"den@3");
        addData( uname , password , email );
    }
    //console.info(JSON.stringify(pathEnd));
    console.info( uname );
    console.info( password );
    console.info( email );


    /*
     for (var i in pathArray) {

         response.send(console.info(i));

     }
 */

    response.send(JSON.stringify("weee"));
}

интересно, может ли кто-нибудь помочь мне с этим, спасибо! И извините, я все еще новичок в этом.
