我正在使用 Java API 在 Amazon S3 中上传和下载文件。直到大约一周前，它一直运行良好，即使我没有触及代码，它也完全停止工作。我想知道是否有解决方案。谢谢!

这是运行良好的代码:

AWSCredentials credentials = new BasicAWSCredentials(ACCESSKEYID, SECRETKEY);
AmazonS3Client s3client = new AmazonS3Client(credentials);
List<String> bucketList = new ArrayList<String>();
    for (Bucket bucket : s3client.listBuckets()) {
        System.out.println(bucket.getName());
    }

这里是错误:

我做了一些研究，有些人认为问题可能出在权限上。但是，我想我已经按照此处的说明进行操作:http://docs.aws.amazon.com/AWSToolkitEclipse/latest/GettingStartedGuide/tke_setup_creds.html#d0e387尽我所能。伙计们，我真的很困。谢谢，我们将不胜感激!

最佳答案

我遇到了同样的问题。解决方案原来是设备错误的日期。尝试更新您的设备日期。原因是 SSL 证书的颁发/到期日期正在根据您的设备日期进行验证。
