使用httpproxy做的代理服务，为什么前端页面的访问的地址必须和请求接口的地址统一

// 新建一个代理 Proxy Server 对象

var proxy = httpProxy.createProxyServer({ target: 'http://192.168.1.102:8080/CpyService/bs' });



// 捕获异常

proxy.on('error', function (err, req, res) {

 res.writeHead(500, {

 'Content-Type': 'text/plain'

 });

 res.end('Something went wrong. And we are reporting a custom error message.');

});







var server = require('http').createServer(function(req, res) {

   

  var pathname = url.parse(req.url).pathname;  

 if(pathname.indexOf("CpyUser") > 0){

   console.log('代理服务', req.url, res)

  //  req.url = req.url.replace('/mspj-mall-admin', '')

  proxy.web(req, res);

  // return;

} else {

  handler (req, res) // 处理静态资源的请求

}



var host = req.url;

host = url.parse(host); host = host.host;



console.log("host:" + req.headers.host);

console.log("client ip:" + (req.headers['x-forwarded-for'] || req.connection.remoteAddress));



});
