AWS DynamoDB扫描输出

Question

I'm using the AWS JS SDK for dynamo, and running a scan to get a list of the items in a table. The results come back but each value is nested inside a key of the attribute type:

For example:

I would expect image: { thumbnail: ' http://foobar.jpg ' }

But I am getting image: { thumbnail: { S: ' http://foobar.jpg ' } }

Is there a way to get the SDK to spit out plain values?

Answer 1

我最终使用这个https://github.com/CascadeEnergy/dynamoDb-marshaler不再需要繁琐的键控

Answer 2

不要直接使用DynamoDb扫描，请使用DynamoDb.DocumentClient（）来简化结果集并提取字段类型标识符。
