【问题描述】：

我正在尝试在 DynamoDB 中创建显示在底部的表，但出现此错误。我知道您不能定义多个 PK，但 GSI-PK 也是如此吗？如何修复错误？

2 validation errors detected: Value '[KeySchemaElement(attributeName=VenueID, keyType=HASH), KeySchemaElement(attributeName=VenueName, keyType=Range), KeySchemaElement(attributeName=CheckInID, keyType=HASH)]' at 'globalSecondaryIndexes.1.member.keySchema' failed to satisfy constraint: Member must have length less than or equal to 2; 
Value 'Range' at 'globalSecondaryIndexes.1.member.keySchema.2.member.keyType' failed to satisfy constraint: Member must satisfy enum value set: [HASH, RANGE]

【解决方案1】：

如果您需要两个属性的索引，请创建两个索引。您不能拥有一个具有两个哈希属性的 BeaconAddr-index 索引。

另外，我想知道您是否误解了某些内容，因为将您的索引命名为 BeaconAddr-index 而不是在 BeaconAddr 上编入索引似乎很奇怪？你打算做什么？

【讨论】：

是的，我可能误解了索引命名。我打算根据`beaconAddr`查询一个场地，然后也根据同一个PK查询签到
