Question

我正在尝试运行一个在DynamoDB中创建表的脚本。创建第一个表就很好，但是第二个表遇到了权限问题，这似乎与IAM有关。

这是一个python安全工具，需要进行初始设置，其中一部分正在创建两个DynamoDB表。我可以很好地创建第一个表，但是遇到第二个表的问题。

用户角色具有广泛的AWS权限，所以我看不出这是个问题。

需要安装Python3.7.3版本。

During handling of the above exception, another exception occurred:

应该创建第二个dynamoDB表。

下面是create_account_table函数

    org_client = boto3.client('organizations')
    paginator = org_client.get_paginator('list_accounts')
    account_iterator = paginator.paginate()
    accounts = []
    for accounts_itr in account_iterator:
        for account in accounts_itr['Accounts']:
            accounts.append({'id': account['Id'], 'name': account['Name'], 'email': account['Email'],
                             'environment': ''})
    dynamodb_client = boto3.client('dynamodb')
    dynamodb_client.create_table(
        AttributeDefinitions=[
            {
                "AttributeName": "id",
                "AttributeType": "S"
            }
        ],
        TableName=argos_account_table,
        KeySchema=[
            {
                "AttributeName": "id",
                "KeyType": "HASH"
            }
        ],
        BillingMode='PAY_PER_REQUEST'
    )

    dynamodb_resource = boto3.resource('dynamodb')
    table = dynamodb_resource.Table(argos_account_table)
    with table.batch_writer() as batch:
        for account in accounts:
            batch.put_item(
                Item={
                    'id': account['id'],
                    'name': account['name'],
                    'email': account['email'],
                    'environment': account['environment'],
                }
)

没有看到如何创建表，我只能告诉你两件事：

您遇到的第一个错误是因为您试图描述一个找不到的表（404错误）

在尝试处理未找到的表错误时，您的代码似乎尝试了ListAccounts调用，该调用取决于您拥有的AWS Organization设置。看来您的用户也没有ListAccounts权限。

您能否张贴一个尝试创建表的代码段，因为在这里我们只能看到您进行了describeTable调用，而不是createTable。

当IAM设置为允许全部时，为什么AWS拒绝许可？
