Question

我尝试添加重试政策（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正确设置的组合。

//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));

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