Boost：copy_file 失败，访问被拒绝，但没有权限问题
我编写了以下例程，以便将目录中的所有文件复制到子目录中 然后删除它们，但我一直在 copy_fail 上拒绝访问，这看起来误导了我。刚刚创建的目标目录中路径正确，文件存在且权限不是只读的。
有什么建议如何寻找问题的根源吗？
我尝试调试，但没有 boost::filesystem 源代码。
任何建议表示赞赏。
void
moveConfigurationFileToSubDirectory()
{
// TODO: Catch errors.
boost::filesystem::path full_path( boost::filesystem::current_path() );
// Create directory subdir if not exist
boost::filesystem::path subdirPath(kSubdirectory);
if ( !boost::filesystem::exists(subdirPath) )
{
PLog::DEV.Development(devVerbose, "%s: creating directory %s", __FUNCTION__, subdirPath.string());
boost::filesystem::create_directories(subdirPath);
} else
PLog::DEV.Development(devVerbose, "%s: directory %s exist", __FUNCTION__, subdirPath.string());
// Iterate through the configuration files defined in the static array
// copy all files with overwrite flag, if successfully delete file (looks like there is not remove)
for (int i = 0; i < kNumberOfConfigurationFiles; i++)
{
boost::filesystem::path currentConfigurationFile(kConfigurationFiles[i]);
try
{
boost::filesystem::copy_file(currentConfigurationFile, subdirPath, boost::filesystem::copy_option::overwrite_if_exists);
boost::filesystem::remove(currentConfigurationFile);
}
catch (exception& e)
{
PLog::DEV.Development(devError, "%s: exception - %s", __FUNCTION__, e.what());
}
}
}
I wrote the following routine in order to copy all files in a directory to a subdirectory
and then remove them, but I keep getting an access denied on the copy_fail which looks misleading to me. Paths are corrects, files exist and permission are not read-only in the destination directory just created.
Any suggestion how to hunt the source of the problem?
I tried to debug, but I don't have the boost::filesystem source code.
Any suggestion is appreciated.

您必须为 subdirPath 指定所需的文件名，而不仅仅是路径。 boost 的 copy_file 不够聪明，无法知道通过指定目录名，您希望文件与源具有相同的名称。
You have to specify the filename you want for subdirPath and not just the path. boost's copy_file isn't smart enough to know that by specifying a directory name, you want the file to have the same name as the source.
在什么操作系统上运行？如果在 Linux/Unix 上，那么您是否考虑过保存源文件的目录的权限（您正在删除 currentConfigurationFile，这意味着保存该文件的目录必须具有写入权限）？
What OS are running this on? If on Linux/Unix then have you considered permissions on directory holding your source files (you are removing currentConfigurationFile, this means that directory holding that file must have write permission)?
