将 PutBucketNotification 与 Amazon SDK 或命令行工具结合使用

将通知配置应用于名为 my-bucket 的存储桶：

aws s3api put-bucket-notification --bucket my-bucket --notification-configuration file://notification.json

文件 notification.json 是当前文件夹中的一个 JSON 文件，用于指定 SNS 主题和要监控的事件类型：

{
  "TopicConfiguration": {
    "Event": "s3:ObjectCreated:*",
    "Topic": "arn:aws:sns:us-west-2:123456789012:s3-notification-topic"
  }
}

SNS 主题必须附加一个 IAM 策略，以允许 Amazon S3 向其发布：

{
 "Version": "2008-10-17",
 "Id": "example-ID",
 "Statement": [
  {
   "Sid": "example-statement-ID",
   "Effect": "Allow",
   "Principal": {
     "Service": "s3.amazonaws.com"
   },
   "Action": [
    "SNS:Publish"
   ],
   "Resource": "arn:aws:sns:us-west-2:123456789012:my-bucket",
   "Condition": {
      "ArnLike": {
      "aws:SourceArn": "arn:aws:s3:*:*:my-bucket"
    }
   }
  }
 ]
}

示例 1：此示例为 S3 事件 ObjectRemovedDelete 配置 SNS 主题配置，并为给定的 s3 存储桶启用通知

$topic =  [Amazon.S3.Model.TopicConfiguration] @{
  Id = "delete-event"
  Topic = "arn:aws:sns:eu-west-1:123456789012:topic-1"
  Event = [Amazon.S3.EventType]::ObjectRemovedDelete
}

Write-S3BucketNotification -BucketName kt-tools -TopicConfiguration $topic

示例 2：此示例为给定存储桶启用 ObjectCreatedAll 的通知，将其发送到 Lambda 函数。

$lambdaConfig = [Amazon.S3.Model.LambdaFunctionConfiguration] @{
  Events = "s3:ObjectCreated:*"
  FunctionArn = "arn:aws:lambda:eu-west-1:123456789012:function:rdplock"
  Id = "ObjectCreated-Lambda"
  Filter = @{
    S3KeyFilter = @{
      FilterRules = @(
        @{Name="Prefix";Value="dada"}
        @{Name="Suffix";Value=".pem"}
      )
    }
  }
}

Write-S3BucketNotification -BucketName ssm-editor -LambdaFunctionConfiguration $lambdaConfig

示例 3：此示例基于不同的键后缀创建 2 个不同的 Lambda 配置，并在单个命令中配置了这两个配置。

#Lambda Config 1

$firstLambdaConfig = [Amazon.S3.Model.LambdaFunctionConfiguration] @{
  Events = "s3:ObjectCreated:*"
  FunctionArn = "arn:aws:lambda:eu-west-1:123456789012:function:verifynet"
  Id = "ObjectCreated-dada-ps1"
  Filter = @{
    S3KeyFilter = @{
      FilterRules = @(
        @{Name="Prefix";Value="dada"}
        @{Name="Suffix";Value=".ps1"}
      )
    }
  }
}

#Lambda Config 2

$secondlambdaConfig = [Amazon.S3.Model.LambdaFunctionConfiguration] @{
  Events = [Amazon.S3.EventType]::ObjectCreatedAll
  FunctionArn = "arn:aws:lambda:eu-west-1:123456789012:function:verifyssm"
  Id = "ObjectCreated-dada-json"
  Filter = @{
    S3KeyFilter = @{
      FilterRules = @(
        @{Name="Prefix";Value="dada"}
        @{Name="Suffix";Value=".json"}
      )
    }
  }
}

Write-S3BucketNotification -BucketName ssm-editor -LambdaFunctionConfiguration $firstLambdaConfig,$secondlambdaConfig
