如何使用AWS_CDK将资源参数从一个堆栈传递到另一堆栈

Question

我正在尝试为2个资源创建两个单独的堆栈，即lambda功能和API网关。以下是我的app.py.py

import aws_cdk as cdk
from Stack.lambda_function.hello_handler_stack import HelloHandlerStack
from Stack.apigateway.hello_handler_apigateway_handler import HelloHandlerApigatewayStack
app = cdk.App()

Stack1 = HelloHandlerStack(app, "HelloHandlerStack", env=cdk.Environment(Account="**",Region="*"))

Stack2 = HelloHandlerApigatewayStack(app, "HelloHandlerApigatewayStack", env=cdk.Environment(Account="**",Region="*"), temp_lambda = Stack1.my_lambda)

app.synth()

hello_handler_stack.py

from constructs import Construct
from aws_cdk import (
    Stack,
    aws_lambda as _lambda,
)

class HelloHandlerStack(Stack):

    def __init__(self, scope: Construct, id: str, **kwargs) -> None:
        super().__init__(scope, id, **kwargs)

        my_lambda = _lambda.Function(
            self, 'HelloHandler',
            runtime=_lambda.Runtime.PYTHON_3_7,
            code=_lambda.Code.from_asset('lambda'),
            handler='hello.handler',
        )
        self.my_lambda = my_lambda

hello_handler_handler_apigateway_handler.py hello_handler_stack.py

from constructs import Construct
from aws_cdk import (
    Stack,
    aws_lambda as _lambda,
    aws_apigateway as apigw,
)


class HelloHandlerApigatewayStack(Stack):
    def __init__(self, scope: Construct, id: str, **kwargs) -> None:
        super().__init__(scope, id, **kwargs)

        apigw.LambdaRestApi(
          self, 'Endpoint',
          handler=kwargs["test_lambda"],
        )

typeerror：stack。 init （）有一个意外的关键字参数 'test_lambda'

我应该能够将关键字参数传递给第二个堆栈并使用它来构建API网关，在调用类时，我还应提供其他参考文献吗？

任何帮助都将受到赞赏。

调试问题。必须在构造函数参数定义中编写关键字参数，该定义正在构造函数调用中传递。

hello_handler_apigateway_handler.py

from constructs import Construct
from aws_cdk import (
    Stack,
    aws_lambda as _lambda,
    aws_apigateway as apigw,
)


class HelloHandlerApigatewayStack(Stack):
    def __init__(self, scope: Construct, id: str, test_lambda, **kwargs) -> None:
        super().__init__(scope, id, **kwargs)
    apigw.LambdaRestApi(
      self, 'Endpoint',
      handler=test_lambda,
    )
