Question

我正在尝试通过AWS CDK创建预算。

这里是代码，这是通过参考官方文档和执行类似操作的TypeScript解决方案拼凑而成的。

email = 'yo@yo.yo'
value = 90.0
subscription = sns_sub.EmailSubscription(email)
topic = sns.Topic(self, id='notification_topic', display_name='budget notifications',
                          topic_name='budget_notifications')
topic.add_subscription(subscription)
budget_data_props = aws_budgets.CfnBudget.BudgetDataProperty(budget_type='COST', time_unit='MONTHLY', 
                                                             budget_name='CDK budget',
                                                             budget_limit=aws_budgets.CfnBudget.SpendProperty(amount=value, unit='USD'))
np = aws_budgets.CfnBudget.NotificationProperty(comparison_operator='GREATER_THAN',
                                                notification_type='FORECASTED', threshold=90.0,
                                                threshold_type='PERCENTAGE')
sub = aws_budgets.CfnBudget.SubscriberProperty(address=topic.topic_arn, subscription_type='SNS')
nws = aws_budgets.CfnBudget.NotificationWithSubscribersProperty(notification=np, subscribers=[sub])

budget_props = aws_budgets.CfnBudgetProps(budget=budget_data_props, notifications_with_subscribers=nws)
budget = aws_budgets.CfnBudget(self, 'cdk budget', budget=budget_props)

我得到的错误是：

错误：

值与联合中的任何类型都不匹配：Wire struct type '@ aws-cdk / aws-budgets.CfnBudgetProps'与预期不符 '@ aws-cdk / aws-budgets.CfnBudget.BudgetDataProperty'，预期对象参考，得到 {“ $ jsii.struct”：{“ fqn”：“ @ aws-cdk / aws-budgets.CfnBudgetProps”，“ data”：{“ budget”：{“ $ jsii.struct”：{“ fqn”：“ @ aws-cdk / aws-budgets.CfnBudget.BudgetDataProperty“，”数据“：{” budgetType“：” COST“，” timeUnit“：” MONTHLY“，” budgetLimit“：{” $ jsii.struct“：{” fqn“ ：“ @ aws-cdk / aws-budgets.CfnBudget.SpendProperty”，“数据”：{“金额”：10，“单位”：“ USD”}}}，“ budgetName”：“ CDK budget“，” costFilters“：null，” costTypes“：null，” plannedBudgetLimits“：null，” timePeriod“：null}}}，” notificationsWithSubscribers“：{” $ jsii.struct“：{” fqn“：” @ aws -cdk / aws-budgets.CfnBudget.NotificationWithSubscribersProperty“，” data“：{” notification“：{” $ jsii.struct“：{” fqn“：” @ aws-cdk / aws-budgets.CfnBudget.NotificationProperty“，” data“：{” comparisonOperator“：” GREATER_THAN“，” notificationType“：” FORECASTED“，” threshold“：90，” thresholdType“：” PERCENTAGE“}}}，” subscribers“：[{” $ jsii.struct“： {“ fqn”：“ @ aws-cdk / aws-budgets.CfnBudget.SubscriberProperty”，“ data”：{“ address”：“ $ {Token [TOKEN.56]}”，“ subscriptionType”：“ SNS”}} }]}}}}}

我正在使用带有类型提示的IDE，所以我对于看起来似乎类型不匹配的情况不知所措。

感谢您的阅读和见识。

使用python并创建一个Construct时，有两个传递prop的选项。直接使用Props对象或将Props对象的参数用作键/值对。您正在混合这两种方法。由于您正在创建道具对象，因此应该直接传递

budget = aws_budgets.CfnBudget(self, 'cdk budget', budget_props)

您也可以用这种方法代替创建Props对象

budget = aws_budgets.CfnBudget(
    self, 'cdk budget', 
    budget=budget_data_props, 
    notifications_with_subscribers=nws
)
