我正在尝试设置一个基本的node.js服务器,并且收到一个我无法弄清楚的错误。我有4个文件:index.js,server.js,router.js,requestHandlers.js
index.js
var server = require("./server");
var router = require("./router");
var requestHandlers = ("./requestHandlers");
var handle = {}
handle["/"] = requestHandlers.start;
handle["/start"] = requestHandlers.start;
handle["/upload"] = requestHandlers.upload;
server.start(router.route, handle);
server.js
var http = require('http');
var url = require("url");
function start(route, handle) {
function onRequest(request, response) {
var pathname = url.parse(request.url).pathname;
console.log("Request for " + pathname + " received"); // 2nd log-- works fine
route(handle, pathname);
response.writeHead(200, {'Content-Type': 'text/plain'});
response.write('Hello World');
response.end();
}
http.createServer(onRequest).listen(8888);
console.log("Server has started."); //1st log -- works fine
};
exports.start = start;
router.js
function route(handle, pathname) {
console.log("About to route a request for " + pathname); //3rd log -- works fine
console.log(handle); // THIS IS THE PROBLEM returns ---> { '/': undefined, '/start': undefined, '/upload': undefined }
console.log(pathname); //works fine -- returns "/"
console.log(typeof handle[pathname]); //undefined
if (typeof handle[pathname] === 'function') {
handle[pathname](); //never called because above evaluates to undefined
}
else {
console.log("No request handler found for " + pathname);
}
}
exports.route = route;
requestHandlers.js //代码永远不会到达
function start () {
console.log("Request handler 'start' was called")
}
function upload () {
console.log("Request handler 'upload' was called")
}
exports.start = start;
exports.upload = upload;
我已经完成了100次,对它正在做的事情充满信心,所以希望我能错过一些小事。谢谢!

我认为你不小心忘记了动词(要求)。
var requestHandlers = require("./requestHandlers");
