aws-sts - AWS - STS 如何将 AWSSecurityTokenServiceClientBuilder 与全局区域结合使用

Question

我用的是

AWSSecurityTokenServiceClient sts_client = new AWSSecurityTokenServiceClient(), 

并且自动设置默认区域(全局)。但这个构造函数已被弃用，建议使用:

AWSSecurityTokenServiceClientBuilder.

我也希望它使用默认区域。我写道:

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

但我有一个异常(exception):

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.

我从未听说过全局区域，但要使用新的未弃用的 Builder 方法指定默认区域，您可以使用:

.withRegion(Regions.DEFAULT_REGION)

所以你的命令是:

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

仅供引用 - 在我的 Regions 枚举版本中，DEFAULT_REGION 是 US_WEST_2。别忘了

导入 com.amazonaws.regions.Regions;

编辑:了解您指定的区域并不重要可能会很有用。生成的STS凭证可以在所有区域使用(因此它们在某种意义上是“全局”的)。
