示例1: regionForUri
import com.amazonaws.services.s3.AmazonS3; //导入方法依赖的package包/类
private String regionForUri(AmazonS3 client, AmazonS3URI uri) {
String bucketRegion = client.getBucketLocation(uri.getBucket());
Region region = Region.fromValue(bucketRegion);
// S3 doesn't have a US East 1 region, US East 1 is really the region
// US Standard. US Standard places the data in either an east coast
// or west coast data center geographically closest to you.
// SigV4 requires you to mention a region while signing a request
// and for the S3's US standard endpoints the value to be used is "us-east-1"
// US West 1 has an endpoint and so is treated as a stand alone region,
// US East 1 doesn't and so is bundled into US Standard
if (region.equals(Region.US_Standard)) {
bucketRegion = "us-east-1";
} else {
bucketRegion = region.toString();
}
return bucketRegion;
}
