Question

我正在使用本地dynamodb docker容器测试boto，在将新项目放入表中时出现此错误。该表存在。

from __future__ import print_function # Python 2/3 compatibility
import boto3
import os

os.environ["AWS_ACCESS_KEY_ID"] = "localaccesskey"
os.environ["AWS_SECRET_ACCESS_KEY"] = "password"

conn = boto3.resource('dynamodb', aws_access_key_id="localaccesskey",  aws_secret_access_key="password", region_name='eu-west-1', endpoint_url="http://localhost:8000")
print(list(conn.tables.all()))


table = conn.Table('Movies')
table.put_item(
   Item={
        'username': 'janedoe',
        'first_name': 'Jane',
        'last_name': 'Doe',
        'age': 25,
        'account_type': 'standard_user',
    }
)

错误：

/usr/bin/python2.7 /home/kshk/PycharmProjects/Skulldogo/eli.py
[dynamodb.Table(name=u'Movies'), dynamodb.Table(name=u'devApiConfig'), dynamodb.Table(name=u'devApiKeys'), dynamodb.Table(name=u'devObjectCache'), dynamodb.Table(name=u'devSessionCache'), dynamodb.Table(name=u'test'), dynamodb.Table(name=u'test1'), dynamodb.Table(name=u'test10')]

    raise ClientError(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (ValidationException) when calling the PutItem operation: One of the required keys was not given a value

任何想法???

DynamoDB在创建新记录时不会自动生成ID。确保提供哈希密钥。

哦，定义时也是范围键。

使用本地dynamodb容器时，python boto3 put_item失败
