android - 系统调用期间的 I/O 错误，连接由 S3 客户端的对等问题重置

Question

尝试将文件(图像、音频)上传到 S3 时，我偶尔会遇到此异常。有解决办法吗？

配置:Android 4x、5x、aws-android-sdk-s3 版本 2.2.14。

Answer 1

解决方案是重试请求。

Connection reset by peer 理论上意味着远端服务器由于通信故障或内部错误而重置连接，尽管在实践中，中间设备(特别是防火墙和 NAT/PAT 设备)也可以制作响应数据包产生同样的错误。

通常这会被解释为互联网流量的结果——有时会出现超出您控制范围的错误。

如果同一请求在其他请求成功时重复抛出错误，则此条件应该仅表示您做错了(您可以纠正的事情)。
