nodejs 请求模块在本地主机上返回 ECONNREFUSED

Question

I am trying to make an api call to my localhost but I always get Error: connect ECONNREFUSED 127.0.0.1:5005 at Object.exports._errnoException (util.js:1022:11)

var url = `http://127.0.0.1:5005/api/entities/myEndpoint?id=121`;
var options = {
      url: url
    };
request.get(options, function(err, response, body) {
  console.log(err, response,body);
});

It does work if I use an IP instead of localhost

Check if your server has bound the port to its external IP only. On Linux, check netstat -tulpen | grep 5005 netstat -tulpen | grep 5005 . The output will contain the Server's listener address, eg 0.0.0.0:5005 or ::5005 both means that the server listens on all Interfaces for port 5005 .

If your result is something like <ip address>:5005 where ip address is different from 127.0.0.1 that means that the server listens on that ip and port combination only and cannot be accessed using localhost , even if you are logged into the server.
