以低权限枚举Windows上的共享文件夹

听起来你好像在指定 RESOURCE_GLOBALNET 对于范围,但是如果不查看代码,就很难判断出哪里出了问题。

如果不知道你尝试了什么,得到了什么,你很难提供帮助。例如,您期望的本地名称是什么,返回的是什么?您是否尝试过使用共享信息503的NetShareEnum?

如果您知道本地路径是什么,可以通过测试来强制执行:(TODO:将所有内容设置为Unicode)

// Helper function to make a name unique.
std::string computername()
{
    static std::string name = []() {
        WCHAR buf[MAX_COMPUTERNAME_LENGTH];
        DWORD len = MAX_COMPUTERNAME_LENGTH;
        GetComputerNameEx(ComputerNameNetBIOS, buf, &len);
        return std::string(buf, buf + len);
    }();
    return name;
}

int main()
{
    std::string dir = "C:\\FindThisShare\\";
    // First, create marker
    std::string testfile = computername() + " 038D2B86-7459-417B-9179-90CEECC6EC9D.txt";
    std::ofstream test(dir + testfile);
    test << "This directory holds files from " << computername() 
         << std::endl;
    test.close();

    // Next, find the UNC path holding it.
    BYTE* buf;
    DWORD numEntries;
    NetShareEnum(nullptr, 1, &buf, MAX_PREFERRED_LENGTH, &numEntries,
                 &numEntries, nullptr);
    auto data = reinterpret_cast<SHARE_INFO_1*>(buf);
    std::string retval;
    for (int i = 0; i != numEntries; ++i)
    {
        auto const& entry = data[i];
        std::wstring tmp(entry.shi1_netname);
        std::string share(tmp.begin(), tmp.end());
        std::string uncdir = "\\\\" + computername() + "\\" + share + "\\";
        if (PathFileExistsA((uncdir + testfile).c_str()))
        {
            printf("Exists");
        }
    }
    remove((dir + testfile).c_str());
    NetApiBufferFree(buf);
}
