구독 속성을 설정하려면

다음 set-subscription-attributes 예제에서는 RawMessageDelivery 속성을 SQS 구독으로 설정합니다.

aws sns set-subscription-attributes \
    --subscription-arn arn:aws:sns:us-east-1:123456789012:mytopic:f248de18-2cf6-578c-8592-b6f1eaa877dc \
    --attribute-name RawMessageDelivery \
    --attribute-value true

이 명령은 출력을 생성하지 않습니다.

다음 set-subscription-attributes 예제에서는 FilterPolicy 속성을 SQS 구독으로 설정합니다.

aws sns set-subscription-attributes \
    --subscription-arn arn:aws:sns:us-east-1:123456789012:mytopic:f248de18-2cf6-578c-8592-b6f1eaa877dc \
    --attribute-name FilterPolicy \
    --attribute-value "{ \"anyMandatoryKey\": [\"any\", \"of\", \"these\"] }"

이 명령은 출력을 생성하지 않습니다.

다음 set-subscription-attributes 예제에서는 SQS 구독에서 FilterPolicy 속성을 제거합니다.

aws sns set-subscription-attributes \
    --subscription-arn arn:aws:sns:us-east-1:123456789012:mytopic:f248de18-2cf6-578c-8592-b6f1eaa877dc \
    --attribute-name FilterPolicy \
    --attribute-value "{}"

이 명령은 출력을 생성하지 않습니다.
