AWS - STS如何與全球區域

Question

使用AWSSecurityTokenServiceClientBuilder我用

AWSSecurityTokenServiceClient sts_client = new AWSSecurityTokenServiceClient(), 

和默認的區域（全球）設置authomatically。但是這個構造函數被去除，推薦使用：

AWSSecurityTokenServiceClientBuilder. 

我希望它也使用默認區域。我寫道：

AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(awsCredentials)).build(); 

，但我有一個例外：

com.amazonaws.SdkClientException: Unable to find a region via the region provider chain. Must provide an explicit region in the builder or setup environment to supply a region.

我從來沒有聽說過全球地區，但指定與新的非棄用生成器方法的默認區域，您可以使用：

.withRegion(Regions.DEFAULT_REGION)

所以，你的命令是：

AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard() .withCredentials(new AWSStaticCredentialsProvider(awsCredentials)) .withRegion(Regions.DEFAULT_REGION.getName()) .build();

僅供參考 - 在我的版本的區域枚舉，DEFAULT_REGION是US_WEST_2。不要忘了

import com.amazonaws.regions.Regions;

編輯：這可能是知道，這不要緊，你指定哪個區域是有用的。生成的STS憑證可以用於所有地區（所以在某種意義上它們是'全球'的）。
