如果您使用的是 Amazon Lex V2，请改为参阅 Amazon Lex V2 指南。

 

如果您使用的是 Amazon Lex V1，我们建议您将机器人升级到 Amazon Lex V2。我们不再向 V1 添加新功能，强烈建议使用 V2 以获得全新的机器人。

适用于 Amazon Lex 的 AWS 托管式策略

AWS 托管式策略是由 AWS 创建和管理的独立策略。AWS 托管式策略旨在为许多常见用例提供权限，以便您可以开始为用户、组和角色分配权限。

请记住，AWS 托管式策略可能不会为您的特定使用场景授予最低权限，因为它们可供所有 AWS 客户使用。我们建议通过定义特定于您的使用场景的客户管理型策略来进一步减少权限。

您无法更改 AWS 托管策略中定义的权限。如果 AWS 更新在 AWS 托管式策略中定义的权限，则更新会影响该策略所附加到的所有主体身份（用户、组和角色）。当新的 AWS 服务启动或新的 API 操作可用于现有服务时，AWS 最有可能更新 AWS 托管式策略。

有关更多信息，请参阅《IAM 用户指南》中的 AWS 托管式策略。
