使用web api检索实体元数据 [英] Retrieving Entity Metadata using web api

问题描述

我们需要检索实体的元数据。
确切要求：我正在读取表格上的字段值，该表格具有实体模式名称。有了这个，我需要获得该Entity的主键模式名称。可能吗？如果是这样，请帮助我。
例如：在该字段中，如果我输入lead，那个web api应该取给我leadid并将其存储在另一个字段中。
2.如果我输入事件，那个网络API应该让我煽动

With that I need to get that Entity's primary key schema name. Is it possible? If so please help me. Eg: in that field if I enter "lead" , that web api should fetch me "leadid" and store it in another field. 2. If I enter "incident" , that web api should get me "incidentid"

推荐答案

你不要需要为此检索实体元数据，主键始终是实体模式名称+id，该规则没有例外。如果您仍想检索元数据，您应该可以通过以下方式进行检索：

You don't need do retrieve entity metadata for that, primary key is always "entity schema name" + "id", there are no exceptions from that rule. If you still want to retrieve metadata, you should be able to do it by calling:

https://crmaddress/api/data/v8.2/EntityDefinitions(LogicalName='account')/Attributes?$select=LogicalName

这将返回实体account的所有属性，主键是没有任何@ odata.type属性的那个

That would return all attributes for entity "account", primary key is the one without any "@odata.type" attribute
