Question

我不知道从什么时候开始，但在我的开发机器上，我使用带有Java的AWS开发工具包得到以下错误：

我可以上传文件，因此凭据似乎没问题，但我似乎无法下载它。我正在使用Play！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AWS上的1.6签名问题。我还没有在我的生产服务器上拥有它，所以它可能与OS X有关，但是我不敢将我的代码部署到生产中，直到我确定它不会破坏为止。

（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

它与CloudStack和SDK版本有关。我降级到1.8.11，这一切都运行良好！

Answer 2

降级到1.8.x或使用s3signer，如：

RewriteRule

Amazon S3 AWS因未知原因开始提供错误代码400
