节点JS请求库抛出错误：使用请求库的getaddrinfo ENOTFOUND

Question

我的代码在我的本地计算机上运行正常，因为我在etc.hosts文件中添加了一个条目来进行DNS转换。但是当我把它放在我的云供应商那一刻它没有为getaddrinfo ENOTFOUND.can任何人帮我解决这个问题。这不是其他问题的重复。另一个使用https.get，但我使用post方法和npm库“request”

request = require('request'),     
var headers = {
    'Authorization': 'Basic MTk3Y2RkY2UwYTBjNDA1NGIyN6MGQyOGRiOWYtOGUwYS00M2ExLWEyMzEtYWY4NTgzZTgyMzk3',
    'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
   };

   var dataString = 'grant_type=authorization_code&code=' + req.query.code + '&redirect_uri=' + callbackurl + '';

   var options = {
    uri: 'https://my.url.com/oauth2/v1/token',
    method: 'POST',
    headers: headers,
    body: dataString,
    family: 4
   };

    function callback(error, response, body) {

    if (!error && response.statusCode == 200) {
     var jsonObj = JSON.parse(body);
     for (var myKey in jsonObj) {
      var value = jsonObj[myKey];
      console
       .log("key:" + myKey + ", value:" + value);
      if (myKey === 'access_token') {
       req.session.accesstoken = value;
       console
        .log('Setting Access Token into session-' + req.session.accesstoken);
      }
     }
     res.render('index.jade');
    } else {
      console.error(error);
     // console.log(response);
     res
      .render(
       'error', {
        'title': 'Authorization error',
        'message': 'Error occured during authorization. Please check with your identity service provider'
       });
    }
   }


   request(options, callback);

我没有对云提供商的操作系统级访问权限。因此，当我在云提供商中托管它时，我无法添加相同的DNS条目。我想要点击的URI是一个公共URI。
