SAM-local 无法使用多个堆栈启动 API

Question

我想将资源添加到我的根堆栈，并以某种方式找到了一个 function，我可以首先像这样首先获取堆栈

   my_api = RestApi.from_rest_api_attributes(self, "RestApi",
                                               rest_api_id='test',
                                               root_resource_id='test'
                                

           )

参考https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_apigateway/README.html#breaking-up-methods-and-resources-across-stacks

然后在获取此堆栈后尝试添加资源

mine_ = my_api.root.add_resource("mine")
mine_.add_method(
            http_method='GET',
            authorizer=api_authorizer
        )

对此我收到了这个错误

任何帮助将不胜感激..

Answer 1

urls must start with a leading slash不是 CDK 抛出的错误。 这是一个 werkzeug 错误，您可以在此处查看有问题的代码。

所以这个错误与你的 CDK 代码没有任何关系。

错误的原因是 SAM 不支持此时测试多个堆栈。 因此，要么将所有内容编译到一个堆栈中，要么避免使用sam-beta-cdk 。
