DynamoDB2 API を使用して boto 2.9.5 で単一クエリまたはバッチクエリを実行する際に問題があります
次のようなバッチ クエリを実行する必要があります。
one_org = Table('[table-name]').batch_get(keys=[
{'key': '[user-id-hash]'},
{'key': '[user-id-hash]'},
{'key': '[user-id-hash]'},
{'key': '[user-id-hash]'},
])
for user in one_org:
for key, value in user.items():
print key, value
私はこの例外を受け取り続けます:
boto.dynamodb2.exceptions.ValidationException: ValidationException: 400 Bad Request
{
u'message': u'The provided key element does not match the schema',
u'__type': u'com.amazon.coral.validate#ValidationException'
}
このメッセージを考えると、キーの名前に問題があると思いますが、私たちのキーはキーと呼ばれているので、私には意味がありません.
以下のスタックトレースを含めました。
