Jawbone JavaScript和Resting Heart Rate数据

Question

我试图通过javascript / node.js从jawbone服务器中提取静息心率数据。我不断阅读财产得到。这是导致错误的代码的一部分。似乎我对接收器静息心率没有正确的命名约定

up.heartrates.get({}, function(err, body) {
    if (err) {
        console.log('Error receiving Jawbone UP data');
    } else {
        jawboneDataheart = JSON.parse(body).data;

        for (i = 0; i < jawboneDataheart.items.length; i++) {
                date = jawboneDataheart.items[i].date.toString(),
                year = date.slice(0,4),
                month = date.slice(4,6),
                day = date.slice(6,8);


            jawboneDataheart.items[i].date = month + '/' + day + '/' + year;
            jawboneDataheart.items[i].title = jawboneDataheart.items[i].title.replace('for ', '');


    }}});
