循环遍历nodejs中插入的方法

Question

我需要插入三件事

1. 国家
2. 状态
3. 城市

async.waterfall方法有insertCountry

insertcountry包含以下逻辑：

var listofCountry = "source file to read the list of country" //a file is there from where i read the countries
listofCountry.forEach(function(objCountry) {
  createCountry(data, next) //with some logic i have my data object already filled.
  createState() //in this method i need to pass the countryId that i have just created.
}, this);

//this is the method that will carry insert of country, **Request data** is a generic method and works fine.

function createCountry(data, next) {

  Request(data, {
      api: "myApi",

      uri: "/Country/create",
      method: "POST",
      data: {
        "name": "data.CountryName",
      }
    },
    function(error, response) {
      if (response && response.data !== undefined && response.data !== null) {
        data.countryId = response.data.CountryId; // the debugger is not coming here.hence not setting the countryId
      } else if (response && response.error !== undefined && response.error !== null) {
        error = response.error;
      }
    });
}

我觉得async或callback的实施方式不正确，我不确定。
