Question

我只能根据我检索到的实体记录中的数据来区分父引用。问题是如何列出特定实体记录的所有子引用？

我有一个帐户实体，我想使用REST API查找所有相关的子实体（联系人等）。

尝试使用以下代码为父级检索相关的子实体：

function RetrieveRelatedChildEntities() {
   var url = Xrm.Utility.getGlobalContext().getClientUrl()  + "/api/data/v9.0/EntityDefinitions(LogicalName='account')?$select=LogicalName,DisplayCollectionName&$expand=ManyToManyRelationships,ManyToOneRelationships,OneToManyRelationships";
   req.open("GET", url, false);
   req.setRequestHeader("OData-MaxVersion", "4.0");
   req.setRequestHeader("OData-Version", "4.0");
   req.setRequestHeader("Accept", "application/json");
   req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
   req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");
   req.onreadystatechange = function () {
    if (this.readyState === 4) {
        req.onreadystatechange = null;
        if (this.status === 200) {
            var results = JSON.parse(this.response);

            for (var i = 0; i < results.OneToManyRelationships.length; i++) {
            }
        }
    }
  }
}

如何查找特定实体记录的子引用？
