尝试通过 request-promise 发出请求，但无法正常工作。

请参阅下面的评论。

有人可以向我解释一下这个 PiA 吗？

var todayOptions = { uri: `http://mlb.mlb.com/gdcross/components/game/mlb/year_${year}/month_${month}/day_${day}/master_scoreboard.json`, 
                     simple: false, 
                     resolveWithFullResponse: true
};

rp(todayOptions)
  .then(function (response){
    console.log(response.body); //RETURNS BODY
    console.log(response.body.data); //RETURNS UNDEFINED EVEN THOUGH IT EXISTS
 })
  .catch(function(error){
    console.log(error);
  });

您需要将 json 选项设置为 true:

var todayOptions = { uri: `http://mlb.mlb.com/gdcross/components/game/mlb/year_${year}/month_${month}/day_${day}/master_scoreboard.json`, 
                     simple: false, 
                     resolveWithFullResponse: true,
                     json: true
};
