节点请求返回空体

Question

这是我的代码：

var request = require('request');
var j = request.jar();

request = request.defaults({jar:j,  followAllRedirects: true});


var urls =new Array();

urls["login"] = "https://www.brooklynfitzone.com/index.php/login";
urls["main"] = "https://www.brooklynfitzone.com/index.php";
urls["reserva"] = "https://www.brooklynfitzone.com/index.php/classes/set_book";

//login


request.post(urls["login"], {form:{user:'user@user.com',pass:'testpass'}},  function(err, httpResponse, html) {
    console.log(httpResponse);
    console.log(j.getCookies());
    console.log(err);
    console.log(html);
});

问题是，使用正确的用户和密码，它返回的正文是空的，我无法获取任何内容。
