使用 REST API 在 apache atlas 中添加实体之间的关系的正确方法是什么？查看 REST API 的文档，我发现很难说出某些字段的含义，哪些是必需的（以及如果不输入会发生什么），或者应该是什么默认值（因为示例使用什么似乎是占位符值（例如，什么是provenanceType或propagateTags字段似乎期望某种枚举值，但从不指定有效选项））。
有人可以提供任何例子来说明这在实际/有效值中会是什么样子吗？例如。如果已经将 2 个实体 E1 和 E2 添加到 Atlas 并希望在两者之间建立关系，则想做类似...
curl -X POST --header 'Content-Type: application/json;charset=UTF-8' --header 'Accept: application/json' -d '{<simplified json>}' 'https://atlas-server-hostname:21000/v2/relationship'

不起作用，并且不确定如何处理错误消息。即使是简单的例子
curl -vv -u admin:admin -X POST --header 'Content-Type: application/json;charset=UTF-8' --header 'Accept: application/json' -d '{ \
"end1": { \

引发类似的无信息错误

请注意，为了获得关系链接所需的 guid，即使 Hortonworks 似乎也只能提供一个糟糕的解决方案。
这里可能出了什么问题？有没有比那些链接到的更好的文档来理解 API？
