Jawbone API 返回每个结果集 10 个 json 对象的分页结果。如何获得其余的分页结果?
该方法的 API文档表明结果集的对象中sleeps
存在一个page_token
参数。next
我下面的输出缺少这个。此外,FAQ表明这page_token
需要一个 INT(可能是纪元)时间戳。
- 第二个:“page_token”参数:如果请求包含“page_token”参数,API 将返回在该 page_token 之前完成的所有锻炼,以相反的顺序(以“limit”或默认值 10 为上限)。page_token 是一个时间戳,并且有一个特殊情况,当请求带有 page_token=0 时,这被解释为传递 page_token = CURRENT_TIMESTAMP,即给予所有锻炼(有限制)
我能够使用 API 进行身份验证并返回一组 10 个结果(第一个分页页面)......但没有page_token
。

"links": {
"next": "/nudge/api/v.1.0/users/jMdCUPXZ-InYXo1kcdOkvA/sleeps?start_time=1424699101&updated_after=0&limit=10&end_time=1438723789"
},
"size": 10
我误解了文档吗?可能是文档已过时(错误)吗?或者更有可能,我完全误解了这一点,并为我的 node.js 编写了可怕的 JS ......
有人可以直截了当地告诉我如何检索所有结果,而不仅仅是第一页吗?
