调用AWS Lambda Java函数的AWS网关收到空正文

Question

public class LambdaFunctionHandler implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
    @Override
    public APIGatewayProxyResponseEvent handleRequest(APIGatewayProxyRequestEvent input, Context context) {
        return new APIGatewayProxyResponseEvent().withBody(input.getBody());
    }
}

{}

null

我想通过POSTMAN传递给API网关POST方法的请求体是

{
    "question":"Hello, how are you doing?"
}

谢谢！

我也试过。我用的密码是

public class LambdaFunctionHandler implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {

    public APIGatewayProxyResponseEvent handleRequest(APIGatewayProxyRequestEvent apiGatewayProxyRequestEvent,
            Context context) {
        return new APIGatewayProxyResponseEvent().withBody(apiGatewayProxyRequestEvent.getBody());
    }
}

我猜您是直接从AWS控制台进行测试。不能直接测试事件触发的lambda。

您必须使用“Amazon API Gateway Proxy”事件创建测试，如下所示。
