Question

我正在使用Learning Locker（学习记录存储）。我成功通过REST API向它插入语句。但我没有成功从中获取陈述。如何在语句上执行查询？ REST API？

Answer 1

I used tinCanPhp library.
this is how you establish a connection with the learning-Locker database and query it in PHP
for example:
$lrs = new TinCan\RemoteLRS(
        'endpoint/public/data/xAPI/',
        '1.0.1',
        'username',
        'key'
);

$actor = new TinCan\Agent(
        [ 'mbox' => 'mailto:dikla@gmail.com' ]
);
$verb = new TinCan\Verb(
        [ 'id' => 'http://adlnet.gov/expapi/verbs/progressed' ]
);
$activity = new TinCan\Activity(
        [ 'id' => 'http://game.t-shirt' ]
);
$statement = new TinCan\Statement(
        [
        'actor' => $actor,
        'verb'  => $verb,
        'object' => $activity,
        ]
);

//get All Actor activity by his unique id
function getAllActorActivity($actorUri){
    global $lrs;
    $actor = new TinCan\Agent(
            [ 'mbox' => $actorUri ]//actorUri should look like this 'mailto:dikla@gmail.com'
    );
    $answer=$lrs->queryStatements(['agent' => $actor]);
    return $answer;
}

如果是通过javascript，您可以使用ADL xAPI Wrapper。它简化了与LRS的通信...... https://github.com/adlnet/xAPIWrapper#get-statements

通常，您在端点/语句上执行GET请求...首先尝试，然后查看是否获得带有“语句”和“更多”属性的json响应。然后，如果可行，您可以使用过滤器缩小结果范围。有关详细信息和选项，请参阅规范。 https://github.com/adlnet/xAPI-Spec/blob/master/xAPI.md#stmtapiget

尝试使用curl命令..它应该返回一个语句结果，尽管来自ADL LRS ......

curl --user tom：1234 GET https://lrs.adlnet.gov/xapi/statements
