Question

我想为AWS SAM当地的Kinesis消费者创建概念证明，以下是我的Kinesis Consumer Java文件

 import com.amazonaws.services.lambda.runtime.Context; import
    com.amazonaws.services.lambda.runtime.RequestHandler; import
    com.amazonaws.services.lambda.runtime.events.KinesisEvent; import
    com.amazonaws.services.lambda.runtime.events.KinesisEvent.KinesisEventRecord;
    public class LambdaFunctionHandler implements
    RequestHandler<KinesisEvent, Integer> {
        @Override
        public Integer handleRequest(KinesisEvent event, Context context) {
            context.getLogger().log("Input: " + event);
            for (KinesisEventRecord record : event.getRecords()) {
                String payload = new String(record.getKinesis().getData().array());
                context.getLogger().log("Payload: " + payload);
            }
            return event.getRecords().size();
        } }

这是我的template.yaml文件

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: A function that processes data from a Kinesis stream.
Resources:
  LambdaFunction:

            StartingPosition: LATEST
            BatchSize: 100
        ListProducts:
          Type: Api
          Properties:
            Path: /lambda
            Method: post      
  KinesisStream:
    Type: "AWS::Kinesis::Stream"
    Properties:
      ShardCount: 1
Outputs:
  FunctionName:
    Description: "Function name"
    Value: !Ref LambdaFunction
  StreamARN:
    Description: "Stream ARN"
    Value: !GetAtt KinesisStream.Arn

首先，如何运行和使用sample.json文件，如果我这样运行，我将遇到错误

在共享凭据文件中找到凭据：〜/ .aws / credentials 找不到LambdaFunctionHandler。模板中的可能选项： ['LambdaFunction']
Error: Function LambdaFunctionHandler not found in template
