Question

我是DynmaoDB的updateTable，我正在传递以下params对象：

{
    "TableName": "movies",
    "AttributeDefinitions": [{
            "AttributeName": "subtitle",
            "AttributeType": "S"
        }],
    "GlobalSecondaryIndexUpdates": [{
            "Create": {
                "IndexName": "subtitle",
                "ProvisionedThroughput": {
                    "ReadCapacityUnits": "5",
                    "WriteCapacityUnits": "5"
                },
                "KeySchema": [{
                        "AttributeName": "subtitle",
                        "KeyType": "HASH"
                    }],
                "Projection": {
                    "ProjectionType": "ALL"
                }
            }
        }],
    "ProvisionedThroughput": {
        "ReadCapacityUnits": "5",
        "WriteCapacityUnits": "5"
    }
}

但是它给了我以下错误：

UnexpectedParameter：在params
UnexpectedParameter：在params.GlobalSecondaryIndexUpdates [0]]

但基于documentation我需要通过它们？！那么为什么它会给我这个错误呢？

更新：

感谢Daniela Miao的建议，通过更改SDK版本解决了我的问题;但我遇到了另一个问题;再次基于documentation，如果我们想创建多个GSI，我们需要在“GlobalSecondaryIndexUpdates”字段中有多个对象，所以我传递了以下参数，但它没有更新GSI;但是，如果我只是创建一个GSI（在“GlobalSecondaryIndexUpdates”字段中传递一个对象，它可以工作）;这是我为创建多个GSI而传递的参数：

{
    "TableName": "movies",
    "AttributeDefinitions": [{
            "AttributeName": "id",
            "AttributeType": "N"
        }, {
            "AttributeName": "title",
            "AttributeType": "S"
        }, {
            "AttributeName": "subtitle",
            "AttributeType": "S"
        }],
    "GlobalSecondaryIndexUpdates": [{
            "Create": {
                "IndexName": "title",
                "ProvisionedThroughput": {
                    "ReadCapacityUnits": "5",
                    "WriteCapacityUnits": "5"
                },
                "KeySchema": [{
                        "AttributeName": "title",
                        "KeyType": "HASH"
                    }],
                "Projection": {
                    "ProjectionType": "ALL"
                }
            }
        }, {
            "Create": {
                "IndexName": "subtitle",
                "ProvisionedThroughput": {
                    "ReadCapacityUnits": "5",
                    "WriteCapacityUnits": "5"
                },
                "KeySchema": [{
                        "AttributeName": "subtitle",
                        "KeyType": "HASH"
                    }],
                "Projection": {
                    "ProjectionType": "ALL"
                }
            }
        }]
}

我是否以错误的格式传递了参数？

谢谢： - ）

您使用的是哪个SDK版本？我认为为现有表添加索引是最近发布的新功能，因此只应在最新的SDK版本2.1.8中支持它：http://aws.amazon.com/releasenotes/SDK/JavaScript/3682546508553819

AWS Update表无效
