Question

我在公司主页＆gt;中创建了 Json响应文件数据字典＆gt; Web脚本＆gt; org＆gt; alfresco＆gt;样品名称：其中一个Alfresco Web的folder.get.json.ftl 脚本（http：// localhost：8080 / alfresco / service / sample / folder / Company％20Home）依据遵守中提到的指导方针 http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Ftasks%2Fws-json-add.html。
成功添加webscript后，我刷新了 Webscripts。
现在正在尝试使用URL调用此websrcipt http：// localhost：8080 / alfresco / service / sample / folder / Company％20Home？format = json 我收到内部错误（500）。

请帮我解决这个问题。在此先感谢!!!!

Answer 1

关键是：

freemarker.core.InvalidReferenceException: Expression verbose is undefined on line 12, column 14 in org/alfresco/sample/folder.get.json.ftl.

您的模板，在第12行，第14个字符，您引用了一个不存在的变量“verbose”。您应该在模型中设置该变量，或者在使用之前检查它是否已定义。
