var http = require('http'), httpProxy = require('http-proxy');
 
// 新建一个代理 Proxy Server 对象
var proxy = httpProxy.createProxyServer({});
 
// 捕获异常
proxy.on('error', function (err, req, res) {
 res.writeHead(500, {
 'Content-Type': 'text/plain'
 });
 res.end('Something went wrong. And we are reporting a custom error message.');
});
 
// 另外新建一个 HTTP 80 端口的服务器,也就是常规 Node 创建 HTTP 服务器的方法。
// 在每次请求中,调用 proxy.web(req, res config) 方法进行请求分发Create your custom server and just call `proxy.web()` to proxy
// a web request to the target passed in the options
// also you can use `proxy.ws()` to proxy a websockets request
//
var server = require('http').createServer(function(req, res) {
 // You can define here your custom logic to handle the request
 // and then proxy the request.
 //var host = req.url;
 //host = url.parse(host); host = host.host;
  
 console.log("host:" + req.headers.host);
 console.log("client ip:" + (req.headers['x-forwarded-for'] || req.connection.remoteAddress));
  
 proxy.web(req, res, { target: 'http://localhost:9080',xfwd : 'true' });
});
 
console.log("listening on port 80")
server.listen(80);

以上就介绍了用nodejs替代nginx做反向代理,包括了require方面的内容,希望对PHP教程有兴趣的朋友有所帮助。
