amazon-web-services - 使用 Lambda 函数运行 AWS Athena 的查询

Question

我在 AWS Athena 上创建了一个表，我可以在该表上运行任何查询而不会出现任何错误:

select * from mytestdb.test

该表有三列， customer_Id, product_Id, price .

我尝试创建一个使用 boto3 为我运行相同查询的 lambda 函数:

import time
import boto3

DATABASE = 'mytestdb'
TABLE = 'test'

output='s3://mybucketons3/'

COLUMN = 'Customer_Id'

def lambda_handler(event, context):

    keyword = 'xyz12345'

    query = "SELECT * FROM %s.%s where %s = '%s';" % (DATABASE, TABLE, COLUMN, keyword)

    client = boto3.client('athena')

    # Execution
    response = client.start_query_execution(
        QueryString=query,
        QueryExecutionContext={
            'Database': DATABASE
        },
        ResultConfiguration={
            'OutputLocation': output,
        }
    )


    return

但是我收到以下错误:

Response:
{
  "errorMessage": "An error occurred (AccessDeniedException) when calling the StartQueryExecution operation: User: arn:aws:sts::076088932150:assumed-role/Test/QueryTest is not authorized to perform: athena:StartQueryExecution on resource: arn:aws:athena:us-west-2:076088932150:workgroup/primary",
  "errorType": "ClientError",

这似乎是一种访问问题，但我不知道为什么，因为我同时拥有 lambda 和 athena db 具有相同的帐户。

正如我在评论中提到的，您的 Lambda 角色应该包含允许与 Athena 服务交互的策略。我还为您的 S3 存储桶添加了完全权限。例子:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1547414166585",
      "Action": [
        "athena:StartQueryExecution"
      ],
      "Effect": "Allow",
      "Resource": "*"
    },
    {
      "Sid": "Stmt1547414166586",
      "Action": [
        "s3:*"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::your-bucket-name/*"
    } 
  ]
}
