我试图创建实验目的简单的node.js代理服务器,我想出了这个简单的脚本一个简单的代理服务器:实现如何使用Node.js
var url = require("url");
var http = require("http");
var https = require("https");
http.createServer(function (request, response) {
var path = url.parse(request.url).path;
if (!path.indexOf("/resource/")) {
var protocol;
path = path.slice(10);
var location = url.parse(path);
switch (location.protocol) {
case "http:":
protocol = http;
break;
case "https:":
protocol = https;
break;
default:
response.writeHead(400);
response.end();
return;
}
var options = {
host: location.host,
hostname: location.hostname,
port: +location.port,
method: request.method,
path: location.path,
headers: request.headers,
auth: location.auth
};
var clientRequest = protocol.request(options, function (clientResponse) {
response.writeHead(clientResponse.statusCode, clientResponse.headers);
clientResponse.on("data", response.write);
clientResponse.on("end", function() {
response.addTrailers(clientResponse.trailers);
response.end();
});
});
request.on("data", clientRequest.write);
request.on("end", clientRequest.end);
} else {
response.writeHead(404);
response.end();
}
}).listen(8484);
我不知道在哪里我错了,但当我尝试加载任何页面时,它给了我以下错误:
http.js:645
this._implicitHeader();
^
TypeError: Object #<IncomingMessage> has no method '_implicitHeader'
at IncomingMessage.<anonymous> (http.js:645:10)

我想知道问题是什么。在node.js中进行调试比在Rhino中要困难得多。任何帮助将不胜感激。
我在自己的电脑上运行了代码。因此,我通过转到“http:// localhost:8484/resource/http:// code.jquery.com/jquery.js”在我的Web浏览器中打开它。它应该已经提取了'jquery.js'文件并将其转发,但是它给了我上述错误。 – 2012-04-19 06:15:23
我最初的猜测是因为你将函数传递给'data'和'end'。你可以尝试传递调用'clientRequest.write()'和'clientRequest.end()'的匿名函数吗?你现在拥有它的方式是传递函数,但是当它被调用时,它将没有适当的上下文('this')。 – loganfsmyth 2012-04-19 06:23:25
你想获取URL内容吗? 'resource'后的URL – 2012-04-19 06:40:00
