Question

请帮助解决问题：

当我启动nats服务器监听4222端口时：那么./gnatsd --addr localhost --port 4222 ./ws-tcp-relay localhost:4222 -p 4223并尝试使用websocket-nat这样的websockets连接（例如在service.js中）：

'use strict';
const nats = require('websocket-nats').connect('ws://localhost:4223');

我收到此错误：

node server.js 
events.js:188
      throw err;
      ^

Error: Unhandled "error" event. (Could not connect to server: Error: getaddrinfo ENOTFOUND localhost:4223 localhost:4223:4223)
    at Client.emit (events.js:186:19)
    at Socket.<anonymous> (/home/dev/projects/node-pub/node_modules/websocket-nats/lib/nats.js:404:14)
    at emitOne (events.js:116:13)
    at Socket.emit (events.js:211:7)
    at emitErrorNT (internal/streams/destroy.js:64:8)
    at _combinedTickCallback (internal/process/next_tick.js:138:11)
    at process._tickCallback (internal/process/next_tick.js:180:9)

但是，如果我尝试使用tcp客户端端口4222直接连接到nat，则连接建立成功：

const nats = require('nats').connect('nats://localhost:4222');

Node.js，ws-tcp-relay with nats：连接错误
