我正在尝试使用 node.js 创建一个 http 缓存代理服务器,在那里我可以转发到任何网页并将它们缓存在我的本地磁盘上!
以下是我的第一次尝试代码:
var http = require('http'),
url = require('url'),
sys = require('url');
var fs = require('fs');
var port = "9010";
// function notFound
function notFound(response){
response.writeHead(404, "text/plain");
response.end("404 : File not Found");
}
//create simple http server with browser requet and browser response
http.createServer(function(b_request, b_response){
//Parse the browser request'url
var b_url = url.parse(b_request.url, true);
if(!b_url.query || !b_url.query.url) return notFound(b_response);
//Read and parse url parameter (/?url=p_url)
var p_url = url.parse(b_url.query.url);
//Initialize Http client
var p_client = http.createClient(p_url.port || 80, p_url.hostname);
//Send request
var p_request = p_client.request('GET', p_url.pathname || "/", {
host: p_url.hostname
});
p_request.end();
//Listen for response
p_request.addListener('response', function(p_response){
//Pass through headers
b_response.writeHead(p_response.statusCode, p_response.headers);
//Pass through data
p_response.addListener('data', function(chunk){
b_response.write(chunk);
});
//End request
p_response.addListener('end', function(){
b_response.end();
});
});
}).listen(port);
console.log("Server running at http://127.0.0.1:" +port + "/");
我想为我的应用程序使用任何缓存库,例如:Node-static(https://github.com/cloudhead/node-static)、静态缓存、....
如果我访问的网站运行良好,我的应用程序将转发给它。如果不是,我的应用程序将获取并返回缓存在我的磁盘上的数据。
有什么解决方案可以解决这个问题吗?
感谢 !
