我正在尝试使用AWS SDK for Java version 2. 得到以下异常：
software.amazon.awssdk.services.s3.model.S3Exception:
The request signature we calculated does not match the signature you provided.
Check your key and signing method. (Service: S3, Status Code: 403, Request ID: DCE23DE2BC35653C)
我的代码片段：
import software.amazon.awssdk.auth.credentials.AwsSessionCredentials;
import software.amazon.awssdk.auth.credentials.StaticCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.s3.S3Client;
....
private software.amazon.awssdk.services.s3.S3Client getS3Client(Region region) {
//Getting values from properties file -- AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN
AwsSessionCredentials awsCreds =
AwsSessionCredentials.create(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN);
S3Client s3 =
S3Client.builder()
.region(region)
.credentialsProvider(StaticCredentialsProvider.create(awsCreds))
.build();
return s3;
}
public void listObjects(Region region, String bucketName) {
S3Client s3 = getS3Client(region);
ListObjectsRequest listObjects = ListObjectsRequest
.builder()
.bucket(bucketName)
.build();
ListObjectsResponse res = s3.listObjects(listObjects); // This throws S3Exception
List<S3Object> objects = res.contents();
....
//Iterate over 'objects' and do something

我已经验证了我的 AWS 凭证并且我的账户具有 PowerUser 访问权限。我查看了以下链接，但它没有帮助，因为我正在使用“AwsSessionCredentials”类
- https://stackoverflow.com/a/30519762/948268 - 提到以句点开头的键。
- https://github.com/aws/aws-sdk-js/issues/86 - 讨论确保正确编码 URI 查询字符串参数值。但就我而言，我使用的是AwsSessionCredentials类。
