不，核心角色和功能不会以您想要的方式限制用户。

您可以尝试一个现成的角色/成员插件。可能有一个可用的选项可以让您限制一个用户的访问。

相反，为页面本身创建自定义帖子类型可能更简单。注册新的帖子类型时，可以使用map_meta_cap 并定义自己的自定义功能。然后，您将创建一个仅具有这些功能的角色，并将该角色分配给该用户，当他们登录时，他们将只能访问其用户配置文件和编辑该特定URL。

例如：

<?php
/* Plugin Name: WPSE Info Page
*/
// Register a new post type called Info (or About, or whatever you choose)
add_action(\'init\', \'wpse_create_cpt\');
function wpse_create_cpt() {
    register_post_type(\'info\',
        array(
            \'label\' => __(\'Info\', \'textdomain\'),
            \'public\'            => true,
            \'show_in_rest\'      => true,
            \'has_archive\'       => false,
            \'hierarchical\'      => false,
            // This is where you define custom capabilities
            \'map_meta_cap\'      => true,
            \'capabilities\'      => array(
                \'edit_post\'                 => \'edit_info_page\',
                \'read_post\'                 => \'read_info_page\',
                \'delete_post\'               => \'delete_info_page\',
                \'create_posts\'              => \'create_info_pages\',
                \'delete_posts\'              => \'delete_info_pages\',
                \'delete_others_posts\'       => \'delete_others_info_pages\',
                \'delete_private_posts\'      => \'delete_private_info_pages\',
                \'delete_published_posts\'    => \'delete_published_info_pages\',
                \'edit_posts\'                => \'edit_info_pages\',
                \'edit_others_posts\'         => \'edit_others_info_pages\',
                \'edit_private_posts\'        => \'edit_private_info_pages\',
                \'edit_published_posts\'      => \'edit_published_info_pages\',
                \'publish_posts\'             => \'publish_info_pages\',
                \'read_private_posts\'        => \'read_private_info_pages\'
            ),
        )
    );
}

// Create a new role that has full capabilities for the Info post type
add_action(\'init\', \'wpse_create_cpt_role\');
function wpse_create_cpt_role() {
    add_role(\'info\', \'Info Editor\');
    // You probably want them to be able to read on the front end
    $info->add_cap(\'read\');
    // And upload files, but that\'s up to you
    $info->add_cap(\'upload_files\');
    // Here\'s where you really decide - should they be able to add, edit, delete
    // or maybe only edit (theirs, others, private, and published)
    // and not delete the page, or add additional pages
    $info->add_cap(\'create_info_pages\');
    $info->add_cap(\'delete_info_pages\');
    $info->add_cap(\'delete_others_info_pages\');
    $info->add_cap(\'delete_private_info_pages\');
    $info->add_cap(\'delete_published_info_pages\');
    $info->add_cap(\'edit_info_pages\');
    $info->add_cap(\'edit_others_info_pages\');
    $info->add_cap(\'edit_private_info_pages\');
    $info->add_cap(\'edit_published_info_pages\');
    $info->add_cap(\'publish_info_pages\');
    $info->add_cap(\'read_private_info_pages\');
}

// Optional - give Admin users the ability to edit the info page
// (Since you\'re using custom capabilities, they can\'t edit unless you do this)
add_action(\'init\', \'wpse_grant_cpt_caps\');
function wpse_grant_cpt_caps() {
    $admin = get_role(\'administrator\');
    // Again, decide which capabilities you want them to have
    // (usually you\'ll want to grant full capabilities to Admins)
    $admin->add_cap(\'create_info_pages\');
    $admin->add_cap(\'delete_info_pages\');
    $admin->add_cap(\'delete_others_info_pages\');
    $admin->add_cap(\'delete_private_info_pages\');
    $admin->add_cap(\'delete_published_info_pages\');
    $admin->add_cap(\'edit_info_pages\');
    $admin->add_cap(\'edit_others_info_pages\');
    $admin->add_cap(\'edit_private_info_pages\');
    $admin->add_cap(\'edit_published_info_pages\');
    $admin->add_cap(\'publish_info_pages\');
    $admin->add_cap(\'read_private_info_pages\');
}
?>

您可以将其作为插件安装以创建CPT和角色，然后您仍然需要创建（或更新）一个用户，为该用户提供新CPT的新角色。如果您以前将该页面发布为另一个帖子类型（例如，一个页面），您将希望复制该信息，将该页面发布为CPT，并删除原始页面。
