通过CLI的AWS DynamoDB放置项的类型无效(unicode v.dict)

问题描述

我想通过命令行将项目添加到DynamoDB表中，但是遇到类型错误.

I would like to add an item to my DynamoDB table via command line, but I've run into a type error.

我要添加的数据非常简单:

The data that I'm trying to add is very simple:

{
  "id": "1"
}

我正在运行的命令同样简单:

The command I'm running is equally simple:

aws dynamodb put-item --table-name my_table --item '{ "id": "1" }'

我得到的错误是:

Invalid type for parameter Item.id, value: 1, type: <type 'unicode'>, valid types: <type 'dict'>

我来自JavaScript背景，所以我对 dict 类型不熟悉.从我从某些阅读的资料中了解到，这是Python吗?如何将数据更改为DynamoDB可以处理的数据?

I come from a JavaScript background, so I'm not familiar with dict types. From what I understand from some of the sources I've read, this is a Python thing? How do I change my data into something that DynamoDB can handle?

推荐答案

您需要添加类型信息(我在这里假设为String)

you need to add the type information (I assume String here)

aws dynamodb put-item --table-name my_table --item '{ "id": {"S": "1" } }'
