Javascript 路由器未定义为Node.js

我是Node.js的新手，我正在尝试创建一个HTTP服务器，但由于某种原因，当我尝试将路由器放入购买URL请求时，它不起作用

我的代码：

Server.js

var url = require("url");
var http = require("http"); 


function start() {
function onRequest(request, response) { 
    var pathname = url.parse(request.url).pathname; 
    console.log("Request received.");       

    route(pathname);

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

http.createServer(onRequest).listen(8888);
console.log("Server has started;");
}

exports.start = start;

var server = require("./server");
var router = require("./router");

server.start(router.route);

function route(pathname) {
    console.log("About to route a request for " + pathname);
}

exports.route = route;

Index.js

var url = require("url");
var http = require("http"); 


function start() {
function onRequest(request, response) { 
    var pathname = url.parse(request.url).pathname; 
    console.log("Request received.");       

    route(pathname);

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

http.createServer(onRequest).listen(8888);
console.log("Server has started;");
}

exports.start = start;

var server = require("./server");
var router = require("./router");

server.start(router.route);

function route(pathname) {
    console.log("About to route a request for " + pathname);
}

exports.route = route;

Router.js

var url = require("url");
var http = require("http"); 


function start() {
function onRequest(request, response) { 
    var pathname = url.parse(request.url).pathname; 
    console.log("Request received.");       

    route(pathname);

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

http.createServer(onRequest).listen(8888);
console.log("Server has started;");
}

exports.start = start;

var server = require("./server");
var router = require("./router");

server.start(router.route);

function route(pathname) {
    console.log("About to route a request for " + pathname);
}

exports.route = route;

当尝试通过Node.js启动服务器时，会显示以下错误：

未定义路由

路由（路径名）

如何使其工作？

您正在将

路由

传递到

启动

函数，但未定义参数，您需要添加一个参数

function start(route) {
    function onRequest(request, response) {
        var pathname = url.parse(request.url).pathname;
        console.log("Request received.");

        route(pathname);

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

    http.createServer(onRequest).listen(8888);
    console.log("Server has started;");
}

谢谢你，乔治，成功了。如果你愿意的话，你可以把它作为一个答案，我将投票并标记为正确的评论。对于这些错误，伙计们，我很抱歉，我对这一点很陌生，有时（很多）会发生那些新手错误。
