如何在wordpress中获取用户激活URL？

function generate_activation_url($user_id, $password) {
    $key = get_password_reset_key($user_id);
    $url = add_query_arg(array(
        'action' => 'rp',
        'key' => $key,
        'login' => rawurlencode($user_login)
    ), wp_login_url());

    return $url;
}

function send_activation_email($user_id, $password) {
    $user = get_user_by('id', $user_id);
    $user_login = $user->user_login;
    $activation_url = generate_activation_url($user_id, $password);
    $message = sprintf(__('Please click the following link to activate your account: %s'), $activation_url);

    add_filter('wp_mail_content_type', 'set_html_content_type');
    wp_mail($user->user_email, __('Activate your account'), $message);
    remove_filter('wp_mail_content_type', 'set_html_content_type');
}

function set_html_content_type() {
    return 'text/html';
}

// 注册新用户时触发的动作钩子
add_action('user_register', 'send_activation_email', 10, 2);
