这是我的 lambda 资源：

Resources:

    myFunction:
        Type: AWS::Serverless::Function # More info about Function Resource: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#awsserverlessfunction
        Properties:
            Description: Enter description of what this specific Lambda does
            CodeUri: hello_world/build/
            Handler: app.lambda_handler
            Runtime: python2.7

            Events:
                testMethod:
                    Type: Api
                    Properties:
                        RestApiId: !Ref ApiGatewayApi
                        Path: testMethod/
                        Method: POST

                /:
                    Type: Api
                    Properties:
                        RestApiId: !Ref ApiGatewayApi
                        Path: /
                        Method: ANY

testMethod和“/”对应swagger文档中的路径。但似乎 cloudformation 让我使用“/”作为 api 事件：

Failed to create the changeset: Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state Status: FAILED. Reason: Transform AWS::Serverless-2016-10-31 failed with: Invalid Serverless Application Specification document. Number of errors found: 1. Resource with id [myFunction/] is invalid. Logical ids must be alphanumeric.

你是对的：你不能命名一个事件“/”，但你仍然可以把它作为你的路径。

尝试将您的“/”事件重命名为仅使用字母数字字符的其他名称。这不会改变事件的行为，并且会满足 CloudFormation 的约束。例子：

       Events:
         apiEvent:
           Type: Api
           Properties:
             RestApiId: !Ref ApiGatewayApi
             Path: /
             Method: ANY
