我没有让最新版本的 node-http-proxy 工作(尽管这在以前的版本中可以工作)。 Node.js 版本是 0.6.12,node-http-proxy 版本是 0.8.0。 基本上,我有一个服务器在端口 10000 上监听,另一台服务器在端口 5000 上监听。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。
最佳答案
您需要将选项传递给 HttpProxy 构造函数,而不是 proxyRequest 函数。
