AWS CloudFormation API GatewayV2路由创建

Question

我正在创建一个模板，用apigatewayv2创建一个http api。

我在模板中对API的定义是：

sfHttpApi:
Type: AWS::ApiGatewayV2::Api
DependsOn: sfLambdaFunction
Properties:
Name: !Sub sfHttpAPI-${Region}-${Env}
ProtocolType: HTTP
Target: !Sub arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:${sfLambdaFunction}/invocations
CredentialsArn: !GetAtt sfApiGatewayRole.Arn
sfApiTriggerLambdaPermission:
Type: "AWS::Lambda::Permission"
Properties:
Action: lambda:InvokeFunction
FunctionName: !GetAtt sfLambdaFunction.Arn
Principal: apigateway.amazonaws.com
SourceArn: !Sub 'arn:${AWS::Partition}:execute-api:${AWS::Region}:${AWS::AccountId}:${sfHttpApi}/' 
sfApiLambdProxyIntegration:
Type: "AWS::ApiGatewayV2::Integration"
Properties:
Description: Lambda Integration
ConnectionType: INTERNET
IntegrationMethod: POST
IntegrationUri: !Sub  "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${sfLambdaFunction.Arn}/invocations"
PayloadFormatVersion: '1.0'
ApiId: !Ref sfHttpApi
IntegrationType: AWS_PROXY
sfRoute:
Type: 'AWS::ApiGatewayV2::Route'
DependsOn:
- sfApiLambdProxyIntegration
Properties:
ApiId: !Ref sfHttpApi
RouteKey: 'POST/'  **??? This is the part I dont know how to set**
AuthorizationType: NONE
Target: !Join 
- /
- - integrations
- !Ref sfApiLambdProxyIntegration

我尝试以不同的方式在路由定义中设置routekey，但在创建堆栈时出错：

提供的路由密钥的格式不适合HTTP协议。格式应为"/"或"$default"(服务：AmazonApiGatewayV2；状态代码：400；错误代码：BadRequestException；请求ID:53198c85-fc41-4c76-89c4-7d2db7a7a5b6(

如何设置routekey？

Answer 1

在POST后面加一个空格，即POST /。
