Amazon S3 AWS 开始给出错误代码 400，原因不明

Question

我不确定从什么时候开始，但在我的开发机器上使用 AWS SDK 和 Java 时出现以下错误：

我可以上传文件，所以凭据似乎没问题，但我似乎没有下载它。我正在使用游戏！框架 (1.2.7) 运行 JDK 1.7 和 AWS SDK 1.9.22.

这可能是什么原因？

最近我确实从 JDK 1.6 切换到 1.7，因为 1.6 与 AWS 的签名问题。我（还）没有在我的生产服务器上安装它，所以它可能与 OS X 相关，但在我确定它不会损坏之前不敢将我的代码部署到生产环境中。

(aws-sdk-java/1.9.22 Mac_OS_X/10.10.3 Java_HotSpot(TM)_64-Bit_Server_VM/24.71-b01/1.7.0_71)

[编辑：] 我的 Java 代码：

AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
ClientConfiguration clientConfig = new ClientConfiguration();
clientConfig.setConnectionTimeout(2500);

AmazonS3 conn = new AmazonS3Client(credentials, clientConfig);
conn.setEndpoint(hostUrl);    
S3Object object = conn.getObject(new GetObjectRequest(bucket, fileKey));

Answer 1

与CloudStack和SDK版本有关。我降级到 1.8.11，一切正常！

Answer 2

降级到 1.8.x 或使用像这样的 s3signer：

ClientConfiguration clientConfig = new ClientConfiguration();
clientConfig.setSignerOverride("S3SignerType");
