誰能幫我看看我的代碼，幫我看看，我是個初學者，弄了好久，還是沒弄出來，哪里出錯了??？獲取到的數據不論是寫到文件，還是讀出來都是亂碼，就這個樣

var?http?=?require('http');
var?querystring?=?require('querystring');
var?Promise?=?require('Promise');?//?若版本過低，可使用bluebird替換
var?cheerio?=?require('cheerio');?//?類似于jQuery，安裝方法：npm?install?cheerio
var?fs?=?require('fs');
var?path?=?require('path');
