我们可以像这样查询 web api 端点：

GET [Organization URI]/api/data/v8.2/accounts?$select=name&$top=3 HTTP/1.1
Accept: application/json
OData-MaxVersion: 4.0
OData-Version: 4.0

当响应包含 aboutobjectid 字段时，我们如何针对该记录发出类似的调用？

{
 "@odata.context": "[Organization URI]/api/data/v8.2/$metadata#accounts(name)",
 "value": [
  {
   "@odata.etag": "W/\"501097\"",
   "name": "Fourth Coffee (sample)",
   "accountid": "89390c24-9c72-e511-80d4-00155d2a68d1",
   "regardingobjectid":"dfdc331f-1cff-4bce-acd7-4815b2e87a30"
  },
 ]
}

是否有odata方式来查询有关objectid，例如：

GET [Organization URI]/api/data/v8.2/Entity?regardingobjectid eq 'dfdc331f-1cff-4bce-acd7-4815b2e87a30'

另一种方法是检索相关的对象 id 值

var req = new XMLHttpRequest();
req.open("GET", Xrm.Page.context.getClientUrl() + "/api/data/v8.1/emails(B8345099-6074-E711-810F-00155D6FD705)?$select=_regardingobjectid_value", true);
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 result = JSON.parse(this.response);
            var _regardingobjectid_value = result["_regardingobjectid_value"];
            var _regardingobjectid_value_formatted = result["_regardingobjectid_value@OData.Community.Display.V1.FormattedValue"];
            var _regardingobjectid_value_lookuplogicalname = result["_regardingobjectid_value@Microsoft.Dynamics.CRM.lookuplogicalname"];
        } else {
            Xrm.Utility.alertDialog(this.statusText);
        }
    }
};
req.send();

*请注意标题以包含 odata 注释。

哪个应该返回：

{
"@odata.context": "http://xxxx/api/data/v8.1/$metadata#emails(_regardingobjectid_value)/$entity",
"@odata.etag": "W/\"633069\"",
"_regardingobjectid_value@Microsoft.Dynamics.CRM.associatednavigationproperty": "regardingobjectid_account_email",
"_regardingobjectid_value@Microsoft.Dynamics.CRM.lookuplogicalname": "account",
"_regardingobjectid_value@OData.Community.Display.V1.FormattedValue": "Coho Winery (sample)",
"_regardingobjectid_value": "b3cc84f2-be0d-e711-8104-00155d6fd705",
"activityid": "b8345099-6074-e711-810f-00155d6fd705"
}

_regardingobjectid_value@Microsoft.Dynamics.CRM.lookuplogicalname给我们实体名称并 _regardingobjectid_value给我们查询相关记录所需的 id：

/api/data/v8.1/accounts(b3cc84f2-be0d-e711-8104-00155d6fd705)

如果我们想过滤相关记录，这应该可以工作。

GET [Organization URI]/api/data/v8.2/accounts?$select=name&$filter=_regardingobjectid_value eq guid

注意：没有单引号的 guid

要从相关实体（单条记录）查询列值，请使用expand. 例如 - 要在客户记录中获取主要联系人详细信息：

?$select=name&$expand=primarycontactid($select=fullname,jobtitle,annualincome)

我会推荐CRM REST Builder来构建查询。
