二、核心代码解析

1. 云服务器ECS创建

from huaweicloudsdkcore.auth.credentials import BasicCredentials
from huaweicloudsdkecs.v2.client import EcsClient

# 配置认证信息
credentials = BasicCredentials(
    ak='your-ak',
    sk='your-sk',
    project_id='your-project-id'
)

# 初始化ECS客户端
client = EcsClient(credentials)

# 创建ECS服务器
create_server_request = {
    "name": "test-server",
    "image_id": "your-image-id",
    "flavor_id": "your-flavor-id",
    "security_group_ids": ["your-security-group-id"],
    "network_id": "your-network-id",
    "public_ip": True
}

create_server_response = client.create_server(create_server_request)
print(create_server_response)

2. 云数据库RDS创建

from huaweicloudsdkcore.auth.credentials import BasicCredentials
from huaweicloudsdkrds.v3.client import RdsClient

# 配置认证信息
credentials = BasicCredentials(
    ak='your-ak',
    sk='your-sk',
    project_id='your-project-id'
)

# 初始化RDS客户端
client = RdsClient(credentials)

# 创建RDS数据库
create_rds_request = {
    "name": "test-rds",
    "engine": "mysql",
    "vpc_id": "your-vpc-id",
    "subnet_id": "your-subnet-id",
    "flavor_id": "your-flavor-id",
    "password": "your-password"
}

create_rds_response = client.create_rds(create_rds_request)
print(create_rds_response)

3. 云存储OBS上传文件

from huaweicloudsdkcore.auth.credentials import BasicCredentials
from huaweicloudsdkobs.v2.client import ObsClient

# 配置认证信息
credentials = BasicCredentials(
    ak='your-ak',
    sk='your-sk',
    project_id='your-project-id'
)

# 初始化OBS客户端
client = ObsClient(credentials)

# 上传文件
upload_file_request = {
    "bucket_name": "your-bucket-name",
    "object_key": "your-object-key",
    "source_file_name": "local-file-path"
}

client.upload_file(upload_file_request)
