我已经定义了AWS::ApiGateway::Method
这样的
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"]]
我的处理程序定义如下
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";
}
}
Request 是一个简单的java pojo,orderId
只有具有必要GETTERS和SETTERS的字段
当我测试API网关时,我在lambda日志中看到,订单ID为null。但是,我确实看到它在日志中作为查询字符串传递...这里是
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", ... }
为什么我的orderId
handler
为空?
答案 0 :(得分:1)
如果您使用AWS_PROXY
集成,API Gateway将忽略您的映射模板。 API网关将以此格式将参数发送到您的Lambda函数。
