代理不适用于快递。好像没有定义

Question

我正在尝试使用 Node.js 上的以下教程在单个服务器上配置多个应用程序：

https://itnext.io/hosting-multiple-apps-on-the-same-server-implement-a-reverse-proxy-with-node-a4e213497345

然后在下面的代码中，代理似乎没有定义： "TypeError: proxy is not a function" 但是代理应该在快递上定义，我说的对吗？它甚至在 express reference

const express = require('express');
const proxy = require('http-proxy-middleware');

const {routes} = require('./config.json');

const app = express();

for(route of routes){
    app.use(
        route.route,proxy({
            target: route.address,
            pathRewrite: (path, req) => {
                return path.split('/').slice(2).join('/');
            }
        })
    );
}
app.listen(1000,()=>{
    console.log('Proxy listening on port 1000');
});

Answer 1

请检查http-proxy-middleware的版本。对于v0.x，你应该这样使用它：

var proxy = require('http-proxy-middleware');

见v0.x readme

对于v1.x.x，你应该这样使用：

const { createProxyMiddleware } = require('http-proxy-middleware');

见v1.x.x readme

Proxy does not work on express. Seems it's not defined

node.js
