無法寫入CSV文件

我想僅使用JavaScript將已爬網的網址存儲在數組中。這裏是我的代碼：無法寫入CSV文件

var AxeBuilder = require('axe-webdriverjs'); 
var WebDriver = require('selenium-webdriver'); 
var json2csv = require('json2csv'); 
var fs = require('fs'); 
var crawled=''; 

var driver = new WebDriver.Builder() 
    .forBrowser('firefox') 
    .build(); 

driver 
    .get('https://www.ally.com') 
    .then(function() { 
    AxeBuilder(driver) 
     .analyze(function (results) { 
     console.log(results.violations); 
     }); 
    }); 

    const CrawlKit = require('crawlkit'); 
const AxeRunner = require('crawlkit-runner-axe'); 

const crawler = new CrawlKit('https://www.ally.com'); 
// You could add a finder here in order to audit a whole network of pages 
crawler.addRunner('aXe', new AxeRunner()); 

crawler.crawl() 
    .then((data) => { 
     { 
     console.log(JSON.stringify(data.results, true, 2)); 
     console.log(data.results.length); 
    } (err) => console.error(err) 



    var crawled = []; 
      for (var i = 0; i < data.results.length; i++) 
      { 
      crawled.push({ 

       'url': data.results[i] 

      }); 
      } 

      }); 
    //storeCSV(crawled); 
console.log(crawled); 
var csv = json2csv({ data: crawled, fields: ['url'] }); 
storeCSV(csv); 


function storeCSV(storeJSArray) { 

    fs.writeFile('C:/Users/AppData/Roaming/npm/node_modules/crawl.csv', storeJSArray, function(err) { 
    if (err) throw err; 
    console.log('File saved!'); 
    }); 
}

預期結果：爲CSV文件

實際行爲：

'Url"

它帶有字段名的空白CSV文件。它沒有捕獲抓取的結果。我錯過了什麼。任何建議，這將是有益的。

數據中沒有'url'字段。你的意思是'helpURL'嗎？

嗨@Chris Browne多數民衆贊成正確。我想寫出console.long（data.results）的結果;進入一個CSV文件 – syndy1989
