dynamics-crm - 此错误是什么意思 "The ' RetrieveMultiple' 方法不支持 Dynamics CRM/api/data/<version> 中类型为“的实体”？

Question

当我尝试执行 GET ../api/data/<version>/officedocuments 的请求时并且至少有 10 个实体，我收到错误:

{"error":{"code":"0x80040800","message":"The 'RetrieveMultiple' method does not support entities of type 'officedocument'."}}

当我尝试获取特定实体记录的完整 JSON 时遇到同样的问题

{"error":{"code":"0x80040800","message":"The 'Retrieve' method does not support entities of type 'roletemplate'."}}

有人可以建议我如何列出所有实体记录，例如 officedocument实体并获取上述的完整 JSON roletemplate记录？

如果它不被允许/不支持意味着我们不能那样做。因此，如果您需要该实体，请使用将 Web api 与 fetchxml 结合使用的解决方法。

https://crmdev.crm.dynamics.com/api/data/v9.1/roletemplates?fetchXml=<fetch> <entity name="roletemplate" > <attribute name="name" /> <attribute name="roletemplateid" /> </entity> </fetch>

明确的查询如下:

<fetch>
  <entity name="roletemplate" >
    <attribute name="name" />
    <attribute name="roletemplateid" />
  </entity>
</fetch>

同样，该查询的解决方法是使用 ExecuteFetchRequest

//Try with IOrganizationService
      var orgService = new OrganizationService(connection);
      //Works
      var orgSvcExecuteFetchResponse = (ExecuteFetchResponse)orgService.Execute(executeFetchReq);
      //Doesn't work
      var orgSvcRetrieveMultipleResponse = orgService.RetrieveMultiple(new FetchExpression(fetch));

      //Try with CrmServiceClient:
      var crmSvcClient = new CrmServiceClient(connectionString);
      //Works
      var crmSvcExecuteFetchResponse = crmSvcClient.Execute(executeFetchReq);
      //Doesn't work
      var crmSvcRetrieveMultipleResponse = crmSvcClient.RetrieveMultiple(new FetchExpression(fetch));
