我正在尝试通过PHP和TinCanPHP API对存储在Learning Locker中的语句执行查询。通过这个答案,我能够从学习储物柜获得回复。以下是响应的一部分:
TinCanLRSResponse Object
(
[success] => 1
[content] => TinCanStatementsResult Object
(
[statements:protected] => Array
(
[0] => TinCanStatement Object
(
[id:protected] => 9ea9e6b6-8278-4545-a02c-c46113f3ba30
[stored:protected] => 2016-02-28T12:04:01.670600+00:00
[authority:protected] => TinCanAgent Object
(
[objectType:protected] => Agent
[name:protected] => New Client
[mbox:protected] => mailto:hello@learninglocker.net
[mbox_sha1sum:protected] =>
[openid:protected] =>
[account:protected] =>

[version:protected] => 1.0.0
[attachments:protected] => Array

[actor:protected] => TinCanAgent Object
(
[objectType:protected] => Agent
[name:protected] => Subhayan Roy
[mbox:protected] => mailto:subhayanroy5@gmail.com
[mbox_sha1sum:protected] =>

[verb:protected] => TinCanVerb Object
(
[id:protected] => http://activitystrea.ms/schema/1.0/search
[display:protected] => TinCanLanguageMap Object
(
[_map:protected] => Array
(
[en-US] => Searched
)
)
)
返回的语句列表具有权限protected
,因此我无法访问它们。如何访问这些报表?我在这里错过了什么?
您需要使用库中内置的方法。在这种情况下,你想要的是getStatement。
$statementResult->content->getStatements();
请参阅此处的文档:http://rusticisoftware.github.io/TinCanPHP/doc/api/latest/classes/TinCan.StatementsResult.html#method_getStatements
要回答您接下来要问的问题(为什么我没有在结果中返回所有语句?),请查看语句结果 getMore 方法,它为您提供了更多 URL,以及远程 LRS moreStatements 方法,该方法接受更多 URL 并获取下一批语句。请参阅此代码示例:https://github.com/garemoko/TinBadgesPHP/blob/b8789042f4af23f0f7927596e8e7f2a06655db72/TinBadges/RemoteLRS.php#L84-L96
