## Amazon Comprehend 定義的動作
<a name="amazoncomprehend-actions-as-permissions"></a>

您可在 IAM 政策陳述式的 `Action` 元素中指定以下動作。使用政策來授予在 AWS中執行操作的許可。在政策中使用動作時，通常會允許或拒絕存取相同名稱的 API 操作或 CLI 命令。不過，在某些情況下，單一動作可控制對多個操作的存取。或者，某些操作需要多種不同的動作。

動作資料表的**存取層級**欄說明動作的分類方式 （列出、讀取、許可管理或標記）。此分類可協助您了解在政策中使用某動作時，該動作授予您的存取層級。如需存取層級的詳細資訊，請參閱[政策摘要中的存取層級](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_understand-policy-summary-access-level-summaries.html)。

「動作」資料表的**資源類型**欄會指出每個動作是否支援資源層級的許可。如果此欄沒有值，您必須在政策陳述式的 `Resource` 元素中指定政策適用的所有資源 ("\$1")。如果資料欄包含資源類型，則您可以在具有該動作的陳述式中指定該類型的 ARN。如果動作具有一或多個必要資源，呼叫者必須具有對這些資源使用動作的許可。表格中的必要資源會以星號 (\$1) 表示。如果您使用 IAM 政策中的 `Resource` 元素限制資源存取，則每種必要的資源類型必須要有 ARN 或模式。某些動作支援多種資源類型。如果資源類型是選用 (未顯示為必要)，則您可以選擇使用其中一種選用資源類型。

「動作」資料表的**條件索引鍵**欄包含您可以在政策陳述式的 `Condition` 元素中指定的索引鍵。如需有關與服務資源相關聯之條件索引鍵的詳細資訊，請參閱「資源類型」資料表的**條件索引鍵**欄。

動作資料表的**相依動作**欄會顯示成功呼叫動作所需的其他許可。除了 動作本身的許可之外，還可能需要這些許可。當動作指定相依動作時，這些相依性可能適用於針對該動作定義的其他資源，而不只是資料表中列出的第一個資源。

**注意**  
資源條件索引鍵會列在[資源類型](#amazoncomprehend-resources-for-iam-policies)資料表中。您可以在「動作」資料表的**資源類型 (\$1必填) **欄中找到適用於動作的資源類型連結。「資源類型」資料表中的資源類型包括**條件索引鍵**欄，其中包含套用至「動作」資料表中動作的資源條件索引鍵。

如需下表各欄的詳細資訊，請參閱[動作資料表](reference_policies_actions-resources-contextkeys.html#actions_table)。

## Amazon Comprehend 定義的資源類型
<a name="amazoncomprehend-resources-for-iam-policies"></a>

此服務會定義下列資源類型，並可用在 IAM 許可政策陳述式的 `Resource` 元素中。[動作表格](#amazoncomprehend-actions-as-permissions)中的每個動作都代表可使用該動作指定的資源類型。資源類型也能定義您可以在政策中包含哪些條件索引鍵。這些索引鍵都會顯示在「資源類型」資料表的最後一欄。如需下表各欄的詳細資訊，請參閱[資源類型資料表](reference_policies_actions-resources-contextkeys.html#resources_table)。
