我已经为用户生成的内容配置了 Tridion，并使用默认/演示模板创建了一个网页，该模板使用文本输入字段来提供评论作者的姓名。评论被接受，但在显示时将用户名显示为“null”。我相信问题在于存储名称，而不是检索它。如果我从 Content Manager UI 中创建评论，然后返回到我的测试网页，则会显示评论以及主持人的姓名。
面向公众的 UGC Web 服务配置了 AllowAnonymousClaimProcessor。（没有这个，评论根本不会保存。）日志显示这显然成功地将丢失的 taf:claim:contentdelivery:webservice:user 转换为基于跟踪 id 的。
当然，想法是不要用这个作为评论的作者。在日志记录中，您还可以看到来自网页文本输入的字符串“Test User”，这似乎映射到 author=com.tridion.storage.ugc.UGCUser@2598a35d，但不久之后存储层搜索 ID 为 null 的用户并找到一个。
我怀疑这是一个配置问题，但正如您所看到的，它很复杂，我不确定在哪里进一步寻找。对它应该如何工作的解释与更具体的实验建议一样受欢迎。
日志输出如下。我已经修剪了很多，但它仍然很长，因为我不知道哪些位可能被证明是相关的：
