QHttp:Error writing reponse to device [复制链接]

我用QHttp下载文件到75%的时候，http ->errorString()报出了：Error writing reponse to device

请问这大概是什么错误阿，谢谢

设备写入响应错误

qhttp.cpp , Line 2964

// if writing to the device does not succeed, quit with error
if (bytesWritten == -1 || bytesWritten < n)
{
     finishedWithError(QLatin1String(QT_TRANSLATE_NOOP("QHttp", "Error writing response to device")), QHttp::UnknownError);
}
