一个 request 请求结果处理有问题

g.js 的 第 55 行的request 改成

request({url: url, json: true}, function (error, response, body) {
    if (!error && response.statusCode === 200) {
        var data = JSON.parse(body);
        var now = (new Date().getTime());
        var expires_in = now + (data.expires_in - 20) * 1000;
        data.expires_in = expires_in;
        resolve(data);
        console.log(data);
    } else {
        reject()
    }
});

 request({url: url, json: true}).then(function (response) {
        console.log('data-----',response);
        var data = response[1];//看是不是这个问题
        var now = (new Date().getTime());
        var expires_in = now + (data.expires_in - 20) * 1000;
        data.expires_in = expires_in;
        resolve(data);
  })

你先看看 response返回是啥再说
