华为云国际站代理商：常见代码段

作为华为云国际站的代理商，常见的代码段主要集中在API调用和SDK的使用上。以下是一些常见的代码段示例：

使用Python调用华为云API

安装依赖

首先需要安装华为云的SDK，可以使用pip安装：

pip install huaweicloudsdkcore huaweicloudsdkecs

配置客户端

from huaweicloudsdkcore.auth.credentials import BasicCredentials
from huaweicloudsdkcore.exceptions import exceptions
from huaweicloudsdkcore.http.http_config import HttpConfig
from huaweicloudsdkecs.v2 import EcsClient

# 替换为实际的AK和SK
ak = 'your-access-key'
sk = 'your-secret-key'
region = 'your-region'

credentials = BasicCredentials(ak, sk)
config = HttpConfig.get_default_config()

client = EcsClient.new_builder() 
    .with_credentials(credentials) 
    .with_region(region) 
    .with_http_config(config) 
    .build()

创建虚拟机实例

from huaweicloudsdkecs.v2 import CreateServersRequest
from huaweicloudsdkecs.v2 import CreateServersRequestBody
from huaweicloudsdkecs.v2 import PrePaidServer

request = CreateServersRequest()
server = PrePaidServer(
    name="test-server",
    flavorRef="s3.large.2",
    imageRef="your-image-id",
    vpcid="your-vpc-id",
    nics=[{
        "subnet_id": "your-subnet-id"
    }],
    root_volume={
        "volumetype": "SATA",
        "size": 40
    },
    availability_zone="your-availability-zone"
)
body = CreateServersRequestBody(server)
request.body = body

try:
    response = client.create_servers(request)
    print(response)
except exceptions.ClientRequestException as e:
    print(e.status_code)
    print(e.request_id)
    print(e.error_msg)

使用Java调用华为云API

引入依赖

在pom.xml中添加华为云SDK依赖：

<dependency>
    <groupId>com.huaweicloud.sdk</groupId>
    <artifactId>huaweicloud-sdk-java</artifactId>
    <version>3.0.43</version>
</dependency>

配置客户端

import com.huaweicloud.sdk.core.auth.BasicCredentials;
import com.huaweicloud.sdk.core.http.HttpConfig;
import com.huaweicloud.sdk.core.ClientBuilder;
import com.huaweicloud.sdk.ecs.v2.EcsClient;
import com.huaweicloud.sdk.ecs.v2.model.*;

BasicCredentials credentials = new BasicCredentials()
    .withAk("your-access-key")
    .withSk("your-secret-key")
    .withProjectId("your-project-id");

HttpConfig config = HttpConfig.getDefaultHttpConfig();

EcsClient client = EcsClient.newBuilder()
    .withCredential(credentials)
    .withHttpConfig(config)
    .withRegion(EcsRegion.valueOf("your-region"))
    .build();

创建虚拟机实例

PrePaidServerNic nic = new PrePaidServerNic()
    .withSubnetId("your-subnet-id");

PrePaidServerRootVolume rootVolume = new PrePaidServerRootVolume()
    .withVolumetype(PrePaidServerRootVolume.VolumetypeEnum.SATA)
    .withSize(40);

PrePaidServer server = new PrePaidServer()
    .withName("test-server")
    .withFlavorRef("s3.large.2")
    .withImageRef("your-image-id")
    .withVpcid("your-vpc-id")
    .withNics(Collections.singletonList(nic))
    .withRootVolume(rootVolume)
    .withAvailabilityZone("your-availability-zone");

CreateServersRequestBody body = new CreateServersRequestBody()
    .withServer(server);

CreateServersRequest request = new CreateServersRequest()
    .withBody(body);

try {
    CreateServersResponse response = client.createServers(request);
    System.out.println(response);
} catch (SdkException e) {
    System.out.println(e.getHttpStatusCode());
    System.out.println(e.getRequestId());
    System.out.println(e.getErrorMsg());
}

以上代码段展示了如何通过Python和Java来调用华为云的API创建虚拟机实例。其他服务的调用可以参考相应的API文档并进行类似的配置和调用。
