xp下上传文件报错 ValidateError Open upload file failed. about aliyun-oss-cpp-sdk

[rfcff]

在ResumableUploadObject调用之前，执行
_access(file_path, 0);
_access(file_path, 6);
这两个函数都正常
struct _stat buf = { 0 };
_stat(file_path, &buf);
出错，oss-cpp-sdk调用_stat64函数判断文件是否存在，在xp下执行一直失败

[rfcff]

经验证，发现vs2015调用_stat函数会失败（vs2015 sp3版本），参考https://stackoverflow.com/questions/32452777/visual-c-2015-express-stat-not-working-on-windows-xp
修改FileSystemUtils.cc函数AlibabaCloud::OSS::GetPathInfo，oss_wstat改用GetFileAttributesEx解决

[rfcff]

已经解决

[rfcff]

GetFileAttributesEx要处理FILETIME跟time_t之间的数据转换

ULARGE_INTEGER ui;
ui.LowPart = fileAttrData.ftCreationTime.dwLowDateTime;
ui.HighPart = fileAttrData.ftCreationTime.dwHighDateTime;
t = ((LONGLONG)(ui.QuadPart - 116444736000000000) / 10000000);
