ADL LRS保存语句，但使用HTTP 500进行响应

Question

我已经在https://github.com/adlnet/ADL_LRS上安装了跟随README.txt的ADL LRS。

我正在用TincanJS (https://github.com/RusticiSoftware/TinCanJS)用以下代码测试它，语句被保存，但响应代码是500。

lrs = new TinCan.LRS(
        {

            ////// This works well
            endpoint: "https://cloud.scorm.com/tc/public/",
            username: "<Test User>",
            password: "<Test Password>",
            allowFail: false

            ////// This returns Internal Error(500)
            endpoint: "my.server:8000/xapi/",
            username: "<My User>",
            password: "<My Password>",
            allowFail: false
        }
);

var statement = new TinCan.Statement(
        {
            actor: {
                "name": "Ac Tor",
                "account": {
                    "homePage": "http://act.or",
                    "name": "actor"
                }
            },
            verb: {
                id: "http://adlnet.gov/expapi/verbs/experienced"
            },
            target: {
                id: "http://rusticisoftware.github.com/TinCanJS"
            }
        }
);

lrs.saveStatement(
        statement,
        {
            callback: function (err, xhr) {
                //...
            }
        }
);

提前谢谢。

Answer 1

log/文件夹中有一些日志文件，这些文件是在安装LRS期间创建的。里面有一个lrs.log文件，它将告诉你是什么导致了500错误。我能够将语句发送到本地LRS实例，没有出现500错误。请回复错误，以便我可以提供帮助。谢谢

除非这只是TinCanJS的怪癖，否则我认为target应该是object。
