如何通过python脚本使用SNS API设置SetPlatformApplicationAttributes

Question

我试图通过python使用boto3库为SNS主题设置Platfrom应用程序属性。

以下是脚本片段

client1 = boto3.client('sns',region_name="us-east-1",aws_access_key_id=access_key,aws_secret_access_key=secret_access_key)

def getSNSattr():
    response = client1.set_platform_application_attributes(
    PlatformApplicationArn='arn:aws:sns:us-east-1:63124104179:testTop1',
    Attributes={
        'key':'SuccessFeedbackSampleRate',
        'value':'100'
    }
    )

下面是我得到的错误。aws文档没有python的例子，也没什么帮助。我不确定我错过了什么。请帮帮忙

*Traceback (most recent call last):
  File "sns2.py", line 20, in <module>
    getSNSattr()

    raise error_class(parsed_response, operation_name)

您在PlatformApplicationArn中放置的ARN不是平台ARN，而是主题ARN。如果要设置主题的属性，请考虑使用SetTopicAttributes API。我还将使用双引号，因为属性是JSON格式的。

所有这些都可以使用 AWS CLI 轻松进行测试：

$ aws sns get-platform-application-attributes --platform-application-arn arn:aws:sns:us-east-1:123456789012:app/GCM/My_App

{
    "Attributes": {
        "FailureFeedbackRoleArn": "arn:aws:iam::123456789012:role/SNSFailureFeedback",
        "EventDeliveryFailure": "arn:aws:sns:us-east-1:123456789012:Test",
        "EventEndpointDeleted": "arn:aws:sns:us-east-1:123456789012:Test",
        "EventEndpointUpdated": "arn:aws:sns:us-east-1:123456789012:Test",
        "Enabled": "true",
        "EventEndpointCreated": "arn:aws:sns:us-east-1:123456789012:Test",
        "SuccessFeedbackRoleArn": "arn:aws:iam::123456789012:role/SNSSuccessFeedback"
    }
}

$ aws sns set-platform-application-attributes --platform-application-arn arn:aws:sns:us-east-1:123456789012:app/GCM/My_App --attributes '{"SuccessFeedbackSampleRate": "100"}'

$ aws sns get-platform-application-attributes --platform-application-arn arn:aws:sns:us-east-1:123456789012:app/GCM/My_App

{
    "Attributes": {
        "FailureFeedbackRoleArn": "arn:aws:iam::123456789012:role/SNSFailureFeedback",
        "EventDeliveryFailure": "arn:aws:sns:us-east-1:123456789012:Test",
        "EventEndpointDeleted": "arn:aws:sns:us-east-1:123456789012:Test",
        "SuccessFeedbackSampleRate": "100",
        "EventEndpointUpdated": "arn:aws:sns:us-east-1:123456789012:Test",
        "Enabled": "true",
        "EventEndpointCreated": "arn:aws:sns:us-east-1:123456789012:Test",
        "SuccessFeedbackRoleArn": "arn:aws:iam::123456789012:role/SNSSuccessFeedback"
    }
}

如果要为应用程序设置属性，请将SetPlatformApplicationAttributes API与应用程序ARN一起使用；如果要为主题设置属性，则将SetTopicAttribute API与主题ARN一起。还使用双引号，因为属性是JSON格式的。

代码应该类似于:

def getSNSattr():
    response = client1.set_platform_application_attributes(
    PlatformApplicationArn="arn:aws:sns:us-east-1:63124104179:app/GCM/testApp1",
    Attributes={
        "SuccessFeedbackSampleRate":"100"
    }
    )
