亞馬遜S3 AWS開始給錯誤代碼400由於未知原因，

Question

我不知道從何時開始，但我的機器上我得到使用AWS SDK與Java以下錯誤：

我可以上傳文件，所以證書看起來沒問題，但我似乎沒有下載它。我正在使用Play！ Framework（1.2.7）運行JDK 1.7和AWS SDK 1.9.22。

這可能是什麼原因造成的？

由於AWS上的1.​​6簽名問題，最近我確實從JDK 1.6切換到了1.7。我還沒有在我的生產服務器上使用它，所以它可能與OS X相關，但不敢將代碼部署到生產環境中，直到我確信它不會中斷。

（AWS-SDK-的java/22年9月1日Mac_OS_X/10.10.3 Java_HotSpot（TM）_64-Bit_Server_VM/24.71-B01/1.7.0_71）

[編輯：] 我的Java代碼：

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

它必須與CloudStack和SDK版本。我降級到1.8.11，一切正常！

Answer 2

降解爲1.8.x的或使用像s3signer：

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