大家好，下午好。简单介绍一下背景，我正在制作作品集，我更喜欢后端而不是前端，所以我不太擅长 CSS 和 HTML。

我知道我们不应该应用图像，但展示图像是展示我想要的预期输出的最佳方式。

您在表格周围看到的黑色部分是我的 .frame 元素，我希望该元素占据所有绿色区域。我尝试将宽度和高度设置为 100%，但它仍然没有占据所需的空间

body {
    background-color: rgba(66, 65, 65, 0.192);
    font-family: Arial, sans-serif;
    margin: 0;
}

h1, p {
    color: rgba(0, 0, 0, 0.8);
    text-align: center;
    margin: 20px 0; /* Avoid large margins */
}

p{
    font-size: 30px;

}

.profile-photo {
    display: block;
    margin: 20px auto; /* Center image */
    width: 250px;
    height: 200px;
    border-radius: 20%;
    object-fit: cover;
    position: relative;
    z-index: 2; /* Ensure it's above the square */
}

.square {
    width: 100%;
    height: 175px;
    background-color: rgba(203, 137, 4, 0.619);
    position: relative; 
    margin-top: -150px; 
    z-index: -1;
}

.frame {
    border : black 2px solid; /*added to visualize the size of .frame*/
    flex-grow: 1;
    width: 90%;
    max-width: 100%;
    margin: 0 auto;
    background-color: white;
    padding: 20px;
    box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
    display: flex;
    flex-direction: column;
}

table {
    width: 100%;
    border-collapse: collapse;
    border-radius: 20%;
}

th, td {
    border: 1px solid #273b38; /* This is the border of the table */
    padding: 8px;   
    text-align: left;   
}

th {
    background-color: #55f3f04d;  /* first colum */
}

Disk Partitions Information:
Drive: C:\ (Local Drive) - Total: 119 GB
Drive: D:\ (Local Drive) - Total: 341 GB
Drive: G:\ (Local Drive) - Total: 15 GB

Pick a path: C:\
"C:\\$Recycle.Bin"
"C:\\$Recycle.Bin\\S-1-5-18"
Error: Unable to iterate through the path C:\ (filesystem error: cannot increment recursive directory iterator: Invalid argument)
Permissions for "C:\\":
rwxrwxrwx
terminate called after throwing an instance of 'std::filesystem::__cxx11::filesystem_error'
  what():  filesystem error: cannot set permissions: Permission denied [C:\]

而对于 DI，只得到错误“无法遍历路径 C:\（文件系统错误：无法增加递归目录迭代器：无效参数）”

我的目标是打印目录中的所有文件，当我收到此错误时，我认为这与权限或其他什么有关，因此我尝试强制所有权限，因为这是我以前在 Python 中所做的，但是我觉得在 C++ 中它不起作用。

void check_permissions(const fs::path& path) {
    fs::perms p = fs::status(path).permissions();

    std::cout << "Permissions for " << path << ":\n";
    std::cout << ((p & fs::perms::owner_read) != fs::perms::none ? "r" : "-")
              << ((p & fs::perms::owner_write) != fs::perms::none ? "w" : "-")
              << ((p & fs::perms::owner_exec) != fs::perms::none ? "x" : "-")
              << ((p & fs::perms::group_read) != fs::perms::none ? "r" : "-")
              << ((p & fs::perms::group_write) != fs::perms::none ? "w" : "-")
              << ((p & fs::perms::group_exec) != fs::perms::none ? "x" : "-")
              << ((p & fs::perms::others_read) != fs::perms::none ? "r" : "-")
              << ((p & fs::perms::others_write) != fs::perms::none ? "w" : "-")
              << ((p & fs::perms::others_exec) != fs::perms::none ? "x" : "-")
              << '\n';
}
void set_permissions(const fs::path& path, fs::perms permissions) {
    fs::permissions(path, permissions);
}

下面是打印所有文件的函数：

void list_files_recursively(const std::string& path) {
    try {
        for (fs::directory_entry entry : fs::recursive_directory_iterator(path)) {
            try {
                std::cout << entry.path() << std::endl;
            } catch (const fs::filesystem_error& e) {
                std::cerr << "Error accessing: " << entry.path() << " (" << e.what() << ")\n";
            }
        }
    } catch (const fs::filesystem_error& e) {
        std::cerr << "Error: Unable to iterate through the path " << path << " (" << e.what() << ")\n";
    }
}

使用 Google Drive G: 时，它可以毫无问题地运行，而且我还尝试跳过我无法访问的文件，但没有效果。

最小可重复示例

#include <iostream>
#include <filesystem>
#include <windows.h>

namespace fs = std::filesystem; 

void print_files(const std::string& path) {
    try {
        for (const auto& entry : fs::recursive_directory_iterator(path, fs::directory_options::skip_permission_denied)) {
            try {
                std::cout << entry.path() << std::endl;
            } catch (const fs::filesystem_error& e) {
                std::cerr << "Error accessing: " << entry.path() << " (" << e.what() << ")\n";
            }
        }
    } catch (const fs::filesystem_error& e) {
        std::cerr << "Error: Unable to iterate through the path " << path << " (" << e.what() << ")\n";
    }
}

int main() {
    std::string path;
    std::cout << "Pick a path: ";
    std::cin >> path;

    print_files(path);

    return 0;
}

它返回相同的错误。

使用另一个 StackOverflow 页面，我写了这个。它不适用于C:\\，但它适用于特定文件夹，但不适用于C:\\。

void print_files(const std::string& path) {
    try {
        for (const auto& entry : fs::recursive_directory_iterator(path, fs::directory_options::skip_permission_denied)) {
            try {
                // Skip system and hidden files
                if ((entry.status().permissions() & fs::perms::others_read) == fs::perms::none) {
                    continue;
                }

                std::cout << "Path: " << entry.path()
                          << " | Type: " << (entry.is_directory() ? "Directory" : "File")
                          << " | Size: " << (entry.is_regular_file() ? std::to_string(entry.file_size()) + " bytes" : "N/A")
                          << std::endl;
            } catch (const fs::filesystem_error& e) {
                std::cerr << "Error accessing: " << entry.path() << " (" << e.what() << ")\n";
            }
        }
    } catch (const fs::filesystem_error& e) {
        std::cerr << "Error: Unable to iterate through the path " << path << " (" << e.what() << ")\n";
    }
}

int main() {
    std::string path;
    std::cout << "Pick a path: ";
    std::cin >> path;

    if (!fs::exists(path)) {
        std::cerr << "Error: Path does not exist.\n";
        return 1;
    }

    print_files(path);

    return 0;
}

// BUT THIS STILL DOESN'T WORK WITH C:\
c++
