http-proxy-middleware

Install

   $ npm install http-proxy-middleware --save-dev

Core concept

context 匹配对应请求的的URL地址, 匹配的请求将被代理到目标主机
options.target 目标主机地址

上图中的 apiProxy 就可以作为一个服务器中间件

Example

var express = require('sxpress');var proxy = require('http-proxy-middleware');var context = '/object/api';//context 可以使一个数组['/object/api','/object2/api',...] var options = {    target: 'http://www.target.org',//目标服务器地址    changeOrigin: true,             //虚拟主机网站需要    headers: {                      //添加token,用于开发        'Authorization': 'Bearer ' + token,        'x-api-version': 1    }}var apiProxy =  proxy(context, options);var app = express();    app.use(apiProxy);    app.listen(3000);
