对流层将S3 LifecycleRule添加到LifecycleConfiguration类

Question

方法签名:我试着用一些不同的方式改变实现，但是没有帮助。

import troposphere.s3 as S3
class LifecycleConfiguration(AWSProperty):
props = {
    'Rules': ([LifecycleRule], True),
}

class LifecycleRule(AWSProperty):
props = {
    'ExpirationDate': (basestring, False),
    'ExpirationInDays': (positive_integer, False),
    'Id': (basestring, False),
    'Prefix': (basestring, False),
    'Status': (basestring, True),
    'Transition': (LifecycleRuleTransition, False),
}

测试实现

myLifecycleConfiguration = S3.LifecycleConfiguration(title='myLifecycleConfiguration',
                                                 Rules=S3.LifecycleRule(title="check"))

错误签名

TypeError: Rules is <class 'troposphere.s3.LifecycleRule'>, expected [<class 'troposphere.s3.LifecycleRule'>]

Answer 1

这很正常，错误消息会告诉您问题出在哪里:规则的‘LifecycleConfiguration’属性应该是LifecycleRule对象的列表(参见代码中的'Rules'：(LifecycleRule，True)，)

但是，当您创建S3.LifecycleConfiguration时，您需要向“Rules”属性提供单个LifecycleRule对象。

你应该写下：

    myLifecycleConfiguration = S3.LifecycleConfiguration(
      title='myLifecycleConfiguration',Rules=[S3.LifecycleRule(title="check")])
