Question

我正在使用odata api，现在我在实体上有一个属性，可以选择：

属性名称是：status 值是：1, 2, 3 名称：done, progress, new

问题是当我使用邮递员获取元数据时，对于字段“状态”，我所获得的全部是其类型整数。

问题我如何从元数据中获取选项名称和值，以便在响应中获取值和名称？

当前，我得到了：

  <Property Name="status" Type="Edm.Int32">
     <Annotation Term="Org.OData.Core.V1.Description" String="" />
  </Property>

但是我想在响应中获取值和名称吗？

Answer 1

假设您只需要int值和实体特定选项集属性的名称，则可以大大简化此操作：

GET [Organization URI]/api/data/v8.2/EntityDefinitions(LogicalName='contact')/Attributes(LogicalName='status')/Microsoft.Dynamics.CRM.PicklistAttributeMetadata?$select=LogicalName&$expand=OptionSet($select=Options),GlobalOptionSet($select=Options)

$select=LogicalName只是它不会返回该属性的所有其他元数据，而$expand=OptionSet($select=Options)是用于本地选项集的，而GlobalOptionSet($select=Options)是用于全局的。如果您知道它是什么类型，则可以跳过另一个类型，但是如果您将此逻辑放在共享库中（不是吗？），那么将两者都添加不会有什么害处：

Answer 2

根据this article，这是一个多步骤过程。

请注意，所有示例均使用HTTP GET。

首先获取实体的MetaData ID（在此示例中，我们使用的是实体“帐户”）： https://myOrg.crm.dynamics.com/api/data/v8.2/EntityDefinitions?$select=LogicalName,MetadataId&$filter=LogicalName eq 'account'

返回：

{
    "@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(LogicalName,MetadataId)",
    "value": [{
        "LogicalName": "account",
        "MetadataId": "70816501-edb9-4740-a16c-6a5efbc05d84"
    }]
}

然后检索属性的MetaDataId（在此示例中，我们使用选项集“ customertypecode”）： https://myOrg.crm.dynamics.com/api/data/v8.2/EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)?$select=LogicalName&$expand=Attributes($select=LogicalName;$filter=LogicalName eq 'customertypecode')

返回：

{
    "@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(LogicalName,Attributes(LogicalName))/$entity",
    "LogicalName": "account",
    "MetadataId": "70816501-edb9-4740-a16c-6a5efbc05d84",
    "Attributes@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)/Attributes(LogicalName)",
    "Attributes": [{
        "@odata.type": "#Microsoft.Dynamics.CRM.PicklistAttributeMetadata",
        "LogicalName": "customertypecode",
        "MetadataId": "4e33af09-ba43-4365-a747-c7e4f9992172"
    }]
}

然后使用实体和属性的MetadataIds查询以获取选项集值： https://myOrg.crm.dynamics.com/api/data/v8.2/EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)/Attributes(4e33af09-ba43-4365-a747-c7e4f9992172)/Microsoft.Dynamics.CRM.PicklistAttributeMetadata?$select=LogicalName&$expand=OptionSet

返回值（截断为2个值）：

{
    "@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)/Attributes/Microsoft.Dynamics.CRM.PicklistAttributeMetadata(LogicalName,OptionSet)/$entity",
    "LogicalName": "customertypecode",
    "MetadataId": "4e33af09-ba43-4365-a747-c7e4f9992172",
    "OptionSet@odata.context": "https://myOrg.crm.dynamics.com/api/data/v8.2/$metadata#EntityDefinitions(70816501-edb9-4740-a16c-6a5efbc05d84)/Attributes(4e33af09-ba43-4365-a747-c7e4f9992172)/Microsoft.Dynamics.CRM.PicklistAttributeMetadata/OptionSet/$entity",
