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

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);
