Python中使用Boto进行Route53子域名创建和管理的步骤

Route53是AWS提供的一项域名解析服务，可以用于管理DNS记录、配置子域名等。Boto是AWS提供的Python SDK，可以用于访问和管理AWS服务。在Python中使用Boto进行Route53子域名的创建和管理，可以按照以下步骤进行操作：

1. 导入Boto库和相关模块

import boto3
from botocore.exceptions import NoCredentialsError

2. 配置Boto客户端

def create_client():
    ACCESS_KEY = '<your-access-key>'
    SECRET_KEY = '<your-secret-key>'
    try:
        client = boto3.client(
            'route53',
            aws_access_key_id=ACCESS_KEY,
            aws_secret_access_key=SECRET_KEY
        )
        return client
    except NoCredentialsError:
        print("无法找到AWS凭证！")

3. 创建子域名

def create_subdomain(client, hosted_zone_id, subdomain_name, target_ip):
    try:
        response = client.change_resource_record_sets(
            HostedZoneId=hosted_zone_id,
            ChangeBatch={
                "Comment": "Create Subdomain",
                "Changes": [
                    {
                        "Action": "CREATE",
                        "ResourceRecordSet": {
                            "Name": subdomain_name,
                            "Type": "A",
                            "TTL": 300,
                            "ResourceRecords": [
                                {
                                    "Value": target_ip
                                }
                            ]
                        }
                    }
                ]
            }
        )
        print("子域名%s创建成功！" % subdomain_name)
    except Exception as e:
        print("子域名创建失败：", str(e))

4. 获取HostedZoneId

def get_hosted_zone_id(client, zone_name):
    try:
        response = client.list_hosted_zones_by_name(
            DNSName=zone_name
        )
        hosted_zone_id = response['HostedZones'][0]['Id']
        return hosted_zone_id
    except Exception as e:
        print("获取HostedZoneId失败：", str(e))

5. 删除子域名

def delete_subdomain(client, hosted_zone_id, subdomain_name):
    try:
        response = client.change_resource_record_sets(
            HostedZoneId=hosted_zone_id,
            ChangeBatch={
                "Comment": "Delete Subdomain",
                "Changes": [
                    {
                        "Action": "DELETE",
                        "ResourceRecordSet": {
                            "Name": subdomain_name,
                            "Type": "A",
                            "TTL": 300
                        }
                    }
                ]
            }
        )
        print("子域名%s删除成功！" % subdomain_name)
    except Exception as e:
        print("子域名删除失败：", str(e))

以上是使用Boto进行Route53子域名创建和管理的基本步骤和代码示例。通过调用相关函数，可以实现创建子域名、删除子域名等操作。具体使用时，需要替换ACCESS_KEY、SECRET_KEY、zone_name、subdomain_name和target_ip等变量为自己的实际值。
