Docker Websocket附加在NodejS中

我想用Websockets連接到Docker API，但是，在任何容器中它只是給我403禁止的錯誤。我不知道我做錯了，沒有它足夠的文檔，但這裏是我的代碼：Docker Websocket附加在NodejS中

var docker = require('docker.io')({ 
    socketPath: false, 
    host: "http://127.0.0.1", 
    port: "4500" 
}); 
var WebSocket = require('ws'); 

var opts = { 
    "AttachStdin": true, 
    "AttachStdout": true, 
    "AttachStderr": true, 
    "Tty": true, 
    "OpenStdin": true, 
    "Cmd": [ 
     "/bin/bash" 
    ], 
    "Image": "ubuntu" 
}; 

docker.containers.create(opts, function(err, result) { 
    if (!err) { 
     var containerId = result.Id; 
     console.log("Container", containerId, "created"); 
     docker.containers.start(containerId, function(err, result) { 
      console.log(result); 
      var ws = new WebSocket('ws://127.0.0.1:4500/v1.7/containers/' + containerId + '/attach/ws?logs=1&stderr=1&stdout=1'); 
      ws.on("open", function() { 
       console.log("ok, open"); 
      }); 

      ws.on("message", function(msg) { 
       console.log("msg", msg); 
      }); 

      ws.on("error", function(msg) { 
       console.log("error", msg); 
      }); 
     }); 
    } else { 
     console.log(err); 
    } 
});

它產生的輸出是：

Container ceeef5eb34acf06dad7d6fea01dd71d9b0283c63b14bc52d49585aa379ec4922 created 

error [Error: unexpected server response (403)]

但我看到的碼頭工人守護進程輸出如下：

如可以看出請求涉及到程序，但是沒有任何跡象表明，爲什麼它給出了一個403 Forbidden錯誤。

看來我需要將127.0.0.1更改爲localhost，它神奇地工作。
