AWSラムダは、私が定義されている

Question

クエリ文字列としてnull値を取得し、私のこの

GetOrdersMethod: 
     Type: "AWS::ApiGateway::Method" 
     Properties: 
      ApiKeyRequired: true 
      AuthorizationType: "AWS_IAM" 
      HttpMethod: "GET" 
      RequestParameters: 
       method.request.querystring.orderId: false 
      ResourceId: 
       Ref: "GetOrdersPathResource" 
      RestApiId: 
       Ref: "GetOrders" 
      Integration: 
       Type: "AWS_PROXY" 
       IntegrationHttpMethod: "POST" 
       RequestTemplates: 
        application/json: !Join ["", ["{","\"orderId\": \"$input.params('orderId')\"","}"]] 
       Uri: !Join ["", ["arn:aws:apigateway:", !Ref "AWS::Region", ":lambda:path/2015-03-31/functions/",!GetAtt GetProgramsLambdaFunction.Arn, "/invocations"]] 

私のハンドラは、この

public class ProgramHandler implements RequestHandler<Request, String>{ 
    private LambdaLogger logger; 

    @Override 
    public String handleRequest(Request request, Context context) { 
     logger = context.getLogger(); 

     logger.log("FROM LOGGER: ======= LAMBDA INVOKED ======"); 
     logger.log("Input value: " +request.getOrderId()); 
     System.out.println("======= LAMBDA INVOKED ======"); 
     System.out.println("Input value: " +request.getMarketplaceId()); 

     return "Lambda Invoked successfully"; 
    } 
} 

のように定義されており、リクエストがorderIdなどと単純なJava POJOであるようAWS::ApiGateway::Method必要なフィールドと設定項目

私がAPIゲートウェイをテストしたとき、私は私のラムダログでは、注文IDがnullであることがわかりました。私は私のhandlerにorderIdヌル取得していますなぜしかし、私はここでそれが

Tue Apr 25 21:57:31 UTC 2017 : Endpoint request body after transformations: {"resource":"/xxxx","path":"/xxxx","httpMethod":"GET","headers":null,"queryStringParameters":{"orderId":"32"},"pathParameters":null,"stageVariables":null,"requestContext":{"accountId":"xxxxxxx","resourceId":"xxxxx","stage":"test-invoke-stage", ... } 

です...それは、ログ上でクエリ文字列として渡されていると思いますか？

AWS_PROXYインテグレーションを使用している場合、APIゲートウェイはマッピングテンプレートを無視します。 APIゲートウェイはこの形式のパラメータをラムダ関数に送信します。
