上传大于 1mb 的文件时出现 SSL 凌空错误(系统调用期间出现 I/O 错误，对等方重置连接)

Question

我尝试添加重试策略（https://stackoverflow.com/a/22169775/2098493）

但是当上传的文件大于1MB时，错误仍然存在。

感谢您的建议。

解决方案是添加 Volley 重试策略并确保后端和服务器 （nodejs/nginx） 最大上传文件大小都设置正确的组合。

//where RETRY_DEFAULT_TIMEOUT_MS = 5000,  RETRY_DEFAULT_MAX_RETRIES = 3, RETRY_DEFAULT_BACKOFF_MULT = 2.0f
    request.setRetryPolicy(new DefaultRetryPolicy(RETRY_DEFAULT_TIMEOUT_MS,
            RETRY_DEFAULT_MAX_RETRIES,
            RETRY_DEFAULT_BACKOFF_MULT));
