无法在控制台上的目录中输出文件？

这是我第一个名为index5.js文件

 var server = require("./nonblockingserver"); var router = require("./nonblockingrouter"); var requestHandlers = require("./requestHandlers4"); var handle = {} handle["/"] = requestHandlers.start; handle["/start"] = requestHandlers.start; handle["/upload"] = requestHandlers.upload; server.start(router.route, handle); 

这是我的第二个名为nonblockingserver.js文件

 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."); route(handle, pathname, response); } http.createServer(onRequest).listen(8888); console.log("Server has started."); } exports.start = start; 

这是我的第三个文件nonblockingrouter.js

 function route(handle, pathname, response) { console.log("About to route a request for " + pathname); if (typeof handle[pathname] === 'function') { handle[pathname](response); } else { console.log("No request handler found for " + pathname); response.writeHead(404, {"Content-Type": "text/plain"}); response.write("404 Not found"); response.end(); } } exports.route = route; 

这是我第三个名为requestHandlers4.js文件

 var exec = require("child_process").exec; function start(response) { console.log("Request handler 'start' was called."); exec("ls -lah", function (error, stdout, stderr) { response.writeHead(200, {"Content-Type": "text/plain"}); response.write(stdout); response.end(); }); } function upload(response) { console.log("Request handler 'upload' was called."); response.writeHead(200, {"Content-Type": "text/plain"}); response.write("Hello Upload"); response.end(); } exports.start = start; exports.upload = upload; 

当我在浏览器中写入http://localhost:8888/start ，它应该显示目录中的所有文件，而不是浏览器上的任何内容。

尝试改变这一点，

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

至，

 response.writeHead(200, {"Content-Type": "text/plain; charset=utf-8"});
