从node.js中的cheerio保存数组

var request = require("request");
var cheerio = require("cheerio");
var pag = [];
request('http://www.tastez.ro/tv.PHP?query=sopcast',function(error,response,body) {
  if (error) {
    return console.error('upload Failed:',error);
  }

  var $= cheerio.load(body);
    links = $(".page a"); //use your CSS SELEctor here
    $(links).each(function(i,link){    
      var   sop = $(this).attr('href');
      pag[i] = sop;  //aici pun val gasite in locuri in array
    });
  pag.push(','); 
});
for (var i=0; i<2; i++){
  console.log(pag[i]);
}

当我运行代码时,它列出了undefined.但是,如果我把这样的代码：

var request = require("request");
var cheerio = require("cheerio");
var pag = [];
request('http://www.tastez.ro/tv.PHP?query=sopcast',error);
  }

  var $= cheerio.load(body);
  links = $(".page a"); //use your CSS SELEctor here
  $(links).each(function(i,link){    
    var sop = $(this).attr('href');
    pag[i] = sop;  //aici pun val gasite in locuri in array
  });
  pag.push(',');
  for (var i=0; i<2; i++){
    console.log(pag[i]);
  }   
});

然后它显示正确的结果,但是当我想稍后使用它时仍未定义.
有人可以帮助我吗？
