使用 AWS 區域 和可用區域

描述區域

要列出您帳戶可用的區域，請調用 Ec2Client 的describeRegions方法。它會傳回 DescribeRegionsResponse。呼叫傳回物件的 regions 方法以取得代表每個區域的 Region 物件清單。

匯入

import software.amazon.awssdk.services.ec2.Ec2Client;
import software.amazon.awssdk.services.ec2.model.DescribeRegionsResponse;
import software.amazon.awssdk.services.ec2.model.DescribeAvailabilityZonesResponse;
import software.amazon.awssdk.services.ec2.model.Ec2Exception;

Code

        try {
            DescribeRegionsResponse regionsResponse = ec2.describeRegions();
            regionsResponse.regions().forEach(region -> {
                System.out.printf(
                    "Found Region %s with endpoint %s%n",
                    region.regionName(),
                    region.endpoint());
                System.out.println();
            });

請參閱（詳見）的完整實例 GitHub。

描述可用區域

若要列出您帳戶可用的每個可用區域，請呼叫 Ec2Client 的describeAvailabilityZones方法。它會傳回 DescribeAvailabilityZonesResponse。呼叫其availabilityZones方法以取得代表每個可用區域的AvailabilityZone物件清單。

匯入

import software.amazon.awssdk.services.ec2.Ec2Client;
import software.amazon.awssdk.services.ec2.model.DescribeRegionsResponse;
import software.amazon.awssdk.services.ec2.model.DescribeAvailabilityZonesResponse;
import software.amazon.awssdk.services.ec2.model.Ec2Exception;

Code

創建 EC2 客戶端。

        software.amazon.awssdk.regions.Region region = software.amazon.awssdk.regions.Region.US_EAST_1;
        Ec2Client ec2 = Ec2Client.builder()
            .region(region)
            .build();

然後調用 describeAvailabilityZones（）並檢索結果。

            DescribeAvailabilityZonesResponse zonesResponse = ec2.describeAvailabilityZones();
            zonesResponse.availabilityZones().forEach(zone -> {
                System.out.printf(
                    "Found Availability Zone %s with status %s in region %s%n",
                    zone.zoneName(),
                    zone.state(),
                    zone.regionName()
                );
                System.out.println();
            });

請參閱（詳見）的完整實例 GitHub。

描述帳戶

要列出有關您帳戶的 EC2 相關信息，請致電 EC2 客戶端的方法。describeAccountAttributes此方法返回一個DescribeAccountAttributesResponse對象。調用此對象的accountAttributes方法來獲取AccountAttribute對象的列表。您可以遍歷列表以檢索對AccountAttribute象。

您可以通過調用對象的attributeValues方法來獲取帳戶的AccountAttribute屬性值。此方法返回AccountAttributeValue對象列表。您可以逐一查看第二個清單以顯示屬性值 (請參閱下列程式碼範例)。

匯入

import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.ec2.Ec2Client;
import software.amazon.awssdk.services.ec2.model.DescribeAccountAttributesResponse;
import software.amazon.awssdk.services.ec2.model.Ec2Exception;

Code

import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.ec2.Ec2Client;
import software.amazon.awssdk.services.ec2.model.DescribeAccountAttributesResponse;
import software.amazon.awssdk.services.ec2.model.Ec2Exception;
