# 允许访问 Athena UDF：策略示例
本主题中的权限策略示例演示了需要允许的操作以及允许执行这些操作的资源。在将类似的权限策略附加到 IAM 身份之前，请仔细检查这些策略并根据您的需求修改它们。
+ [Example Policy to Allow an IAM Principal to Run and Return Queries that Contain an Athena UDF Statement](#udf-using-iam)
+ [Example Policy to Allow an IAM Principal to Create an Athena UDF](#udf-creating-iam)
**Example ：允许 IAM 主体运行并返回包含 Athena UDF 语句的查询**
以下基于身份的权限策略允许用户或其他 IAM 主体执行使用 Athena UDF 语句运行查询所需的操作。
```

**权限说明**
| 允许的操作 | 说明 |
| --- | --- |
| "athena:StartQueryExecution",
"athena:GetQueryResults",
"athena:GetWorkGroup",
"athena:StopQueryExecution",
"athena:GetQueryExecution",
| 在 `MyAthenaWorkGroup` 工作组中运行查询所需的 Athena 权限。 |
| "s3:PutObject",
"s3:GetObject",
"s3:AbortMultipartUpload"
| `s3:PutObject` 和 `s3:AbortMultipartUpload` 允许将查询结果写入由 `arn:aws:s3:::{{MyQueryResultsBucket}}/*` 资源标识符指定的查询结果存储桶的所有子文件夹，其中 {{MyQueryResultsBucket}} 是 Athena 查询结果存储桶。有关更多信息，请参阅 [使用查询结果和最近查询](querying.md)。
`s3:GetObject` 允许读取指定为 `arn:aws:s3:::{{MyQueryResultsBucket}}` 的资源的查询结果和查询历史记录，其中 {{MyQueryResultsBucket}} 是 Athena 查询结果存储桶。有关更多信息，请参阅 [使用查询结果和最近查询](querying.md)。
`s3:GetObject` 还允许从指定为 `"arn:aws:s3:::{{MyLambdaSpillBucket}}/{{MyLambdaSpillPrefix}}*"` 的资源中读取，其中 {{MyLambdaSpillPrefix}} 在被调用的一个或多个 Lambda 函数的配置中指定。 |
| "lambda:InvokeFunction"
| 允许查询调用 Resource 块中指定的 AWS Lambda 函数。例如 arn:aws:lambda:\*:{{MyAWSAcctId}}:function:{{MyAthenaLambdaFunction}}，其中 {{MyAthenaLambdaFunction}} 指定要调用的 Lambda 函数的名称。如示例中所示，可以指定多个函数。 |
**Example ：允许 IAM 主体创建 Athena UDF**

| 允许创建和管理列为资源的 Lambda 函数。在此示例中，资源标识符 `arn:aws:lambda:*:{{MyAWSAcctId}}:function:{{MyAthenaLambdaFunctionsPrefix}}*` 中使用名称前缀，其中 {{MyAthenaLambdaFunctionsPrefix}} 是一组 Lambda 函数的名称中使用的共享前缀，因此它们不需要单独指定为资源。您可以指定一个或多个 Lambda 函数资源。 |
| "s3:GetObject"
| 允许读取 AWS Serverless Application Repository 所需的存储桶，如资源标识符 arn:aws:s3:::awsserverlessrepo-changesets-{{1iiv3xa62ln3m}}/\* 所指定。 |
| "cloudformation:*"
| 允许由资源 {{MyCFStackPrefix}} 指定的 CloudFormation 堆栈的创建和管理。这些堆栈和堆栈集是 AWS Serverless Application Repository 部署连接器和 UDF 的方式。 |
| "serverlessrepo:*"
| 允许在由资源标识符 arn:aws:serverlessrepo:\*:\*:applications/\* 指定的 AWS Serverless Application Repository 中搜索、查看、发布和更新应用程序。 |
