我正在尝试在D2L LMS中使用ContentItemSelectionRequest创建外部链接,但出现500错误。
错误:[https://www.screencast.com/t/Xso2JopkTy][1]
我在远程插件中创建了Quicklink(CIM)。
下面是我正在使用的表格。
<form action="content_item_return_url" method="post" encType="application/x-www-form-urlencoded">
<input type="hidden" name="lti_message_type" value="ContentItemSelection" />
<input type="hidden" name="lti_version" value="LTI-1p0" />
<input type="hidden" name="content_items" value="{"@context":"http:\/\/purl.imsglobal.org\/ctx\/lti\/v1\/ContentItem","@graph":{"@type":"LtiLinkItem","mediaType":"application\/vnd.ims.lti.v1.ltilink","title":"UC LTI 10345","text":"LTI Testing","url":"https:\/\/www.ucertify.com\/lti.php","@id":"https:\/\/www.ucertify.com\/lti.php"}}" />
