我没有得到最新版本的 node-http-proxy 工作（虽然这曾经在以前的版本中工作）。Node.js 版本为 0.6.12，node-http-proxy 版本为 0.8.0。基本上，我有一台服务器监听端口 10000，另一台监听端口 5000。我想将所有以 /api 开头的请求代理给最后一个人（在删除此前缀之后）。

我的代码是：

var express = require("express");
var httpProxy = require('http-proxy');
var cluster = require('cluster');
var fs = require('fs');

// Use http server for local tests
var app = express.createServer();

// Proxy request targeting API
app.all('/api/*',function(req, res){

  // Remove '/api' part from query string
  req.url = '/' + req.url.split('/').slice(2).join('/');

  // Create proxy
  var proxy = new httpProxy.HttpProxy();
  proxy.proxyRequest(req, res, {
    target: {
      host: 'localhost',
      port: 5000
    }
  });
});

// Handle static files
app.use(express.static(__dirname + '/public'));

// Run application
app.listen(10000);

静态文件已正确提供，但是当涉及代理内容时，我收到此错误： 

Error: Both `options` and `options.target` are required.

我已按要求添加了目标，但仍然出现相同的错误。

您需要将选项传递给 HttpProxy 构造函数，而不是 proxyRequest 函数。

另外，你可能一直想说 var proxy = new httpProxy.RoutingProxy();
