如何通过python脚本使用SNS API设置SetPlatformApplication属性

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

下面是脚本的片段

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文档中没有python示例，也没有太多帮助。我不确定我在这里错过了什么。请帮忙

*Traceback (most recent call last):

AWS文件供参考：

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。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，请将SetTopicAttributes API与主题ARN一起使用。还可以使用双引号，因为属性是JSON格式的

代码应该如下所示：

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