无服务器框架 Dynamo DB Table 带排序键的资源定义

Question

我的 serverless.yml 目前有一些代码是这样的。

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

我的目标是创建一个 table，其中包含主键 userId、排序键 visitId 以及用于评论、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 table 和二级索引的 KeySchema 不一致。

我做错了什么？

编辑：我尝试的另一种尝试

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 类型的数据库，在 Table 创建期间无需定义所有键。同样从 AWS 文档中可以清楚地看出，在属性定义中，您必须指定密钥架构和索引。

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
