amazon-web-services - 带排序键的无服务器框架Dynamo DB表资源定义

Question

目前，在我的serverless.yml中有一些这样的代码。

resources:
  Resources:
    uploadBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: ${self:service}-${self:custom.stage}-uploads
    visitsTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: ${self:custom.visitsTable}
        AttributeDefinitions:
          - AttributeName: userId
            AttributeType: S
          - AttributeName: visitId
            AttributeType: S
          - AttributeName: comments
            AttributeType: S
          - AttributeName: attachments
            AttributeType: S
          - AttributeName: ph
            AttributeType: N
          - AttributeName: ch
            AttributeType: N
        KeySchema:
          - AttributeName: userId
            KeyType: HASH
          - AttributeName: visitId
            KeyType: HASH
        ProvisionedThroughput:
            ReadCapacityUnits: 5
            WriteCapacityUnits: 5

我的目标是使用主键userId创建表，对键visitId进行排序，并具有用于注释，附件，ph和ch的字段。当我尝试sls deploy时，出现以下错误。

无服务器错误---------------------------------------

发生错误:visitsTable-属性AttributeDefinitions与表的KeySchema和辅助索引不一致。

我在这里做错了什么？

编辑:我尝试了

resources:
  Resources:
    uploadBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: ${self:service}-${self:custom.stage}-uploads
    visitsTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: ${self:custom.visitsTable}
        AttributeDefinitions:
          - AttributeName: userId
            AttributeType: S
          - AttributeName: visitId
            AttributeType: S
        KeySchema:
          - AttributeName: userId
            KeyType: HASH
          - AttributeName: visitId
            KeyType: RANGE
        ProvisionedThroughput:
            ReadCapacityUnits: 5
            WriteCapacityUnits: 5

AWS DynamoDb是一个NO-SQL类型数据库，无需在创建表期间定义所有键。从AWS文档中还可以清楚地看到，在Attribute Definition中，您必须指定Key模式和索引。

An array of attributes that describe the key schema for the table and indexes.

请按以下方式编辑您的代码

resources:
  Resources:
    uploadBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: ${self:service}-${self:custom.stage}-uploads
    visitsTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: ${self:custom.visitsTable}
        AttributeDefinitions:
          - AttributeName: userId
            AttributeType: S
          - AttributeName: visitId
            AttributeType: S
        KeySchema:
          - AttributeName: userId
            KeyType: HASH
          - AttributeName: visitId
            KeyType: RANGE
        ProvisionedThroughput:
            ReadCapacityUnits: 5
            WriteCapacityUnits: 5
