fastadmin(1)目錄生成分析

項目需要一個後臺管理，選擇了fastadmin。下載了插件

一個前端會員的管理拓展。系統自帶了會員目錄規則。

添加了一個測試目錄，但是在前端怎麼也無法顯示。然後簡單分析了一下。

D:\a\b\application\user\controller\Index.php

在前端控制器找到了Index方法，這裏渲染了menulist

    /**
     * 會員中心
     */
    public function index()
    {
        //左側菜單
        list($menulist, $navlist, $fixedmenu, $referermenu) = $this->auth->getSidebar([
            'dashboard' => 'hot',
        ], $this->view->site['fixedpage']);
        $action = $this->request->request('action');
        if ($this->request->isPost()) {
            if ($action == 'refreshmenu') {
                $this->success('', null, ['menulist' => $menulist, 'navlist' => $navlist]);
            }
        }
        $this->view->assign('menulist', $menulist);
        $this->view->assign('navlist', $navlist);
        $this->view->assign('fixedmenu', $fixedmenu);
        $this->view->assign('referermenu', $referermenu);
        $this->view->assign('title', __('User center'));
        return $this->view->fetch();
    }

menulist是在這裏賦值的

        list($menulist, $navlist, $fixedmenu, $referermenu) = $this->auth->getSidebar([
            'dashboard' => 'hot',
        ], $this->view->site['fixedpage']);

跳轉到getSidebar

D:\a\b\application\common\library\UserAuth.php

    /**
     * 獲取左側菜單欄
     *
     * @param array $params URL對應的badge數據
     * @return string
     */
    public function getSidebar($params = [], $fixedPage = 'dashboard')
    {
        $colorArr = ['red', 'green', 'yellow', 'blue', 'teal', 'orange', 'purple'];
        $colorNums = count($colorArr);
        $badgeList = [];
        $module = request()->module();
        // 生成菜單的badge
        foreach ($params as $k => $v) {
            $url = $k;
            if (is_array($v)) {
                $nums = isset($v[0]) ? $v[0] : 0;
                $color = isset($v[1]) ? $v[1] : $colorArr[(is_numeric($nums) ? $nums : strlen($nums)) % $colorNums];
                $class = isset($v[2]) ? $v[2] : 'label';
            } else {
                $nums = $v;
                $color = $colorArr[(is_numeric($nums) ? $nums : strlen($nums)) % $colorNums];
                $class = 'label';
            }
            //必須nums大於0才顯示
            if ($nums) {
                $badgeList[$url] = '<small class="' . $class . ' pull-right bg-' . $color . '">' . $nums . '</small>';
            }
        }
        // 讀取用戶當前擁有的權限節點
        $userRule = $this->getRuleList();
        $selected = $referer = [];
        $refererUrl = Session::get('referer');
        $pinyin = new \Overtrue\Pinyin\Pinyin('Overtrue\Pinyin\MemoryFileDictLoader');
        // 必須將結果集轉換爲數組
        //$ruleList = collection(UserRule::where('status', 'normal')->where('ismenu', 1)->order('weigh', 'desc')->select())->toArray();//->cache("__usermenu__")
        $ruleList = $this->getMenuList();
        foreach ($ruleList as $k => &$v) {
            /*if (!in_array($v['name'], $userRule)) {
             unset($ruleList[$k]);
             continue;
             }*/
            $v['icon'] = $v['icon'] . ' fa-fw';
            $v['url'] = '/' . $module . '/' . $v['name'];
            $v['badge'] = isset($badgeList[$v['name']]) ? $badgeList[$v['name']] : '';
            $v['py'] = $pinyin->abbr($v['title'], '');
            $v['pinyin'] = $pinyin->permalink($v['title'], '');
            $v['title'] = __($v['title']);
            //$select_id = $v['name'] == $fixedPage ? $v['id'] : $select_id;

        $selected && $selected['url'] = url($selected['url']);
        $referer && $referer['url'] = url($referer['url']);

        $select_id = $selected ? $selected['id'] : 0;
        $menu = $nav = '';
        //是否啓用多級菜單導航
        if (Config::get('fastadmin.multiplenav')) {
            $topList = [];
            foreach ($ruleList as $index => $item) {
                if (!$item['pid']) {
                    $topList[] = $item;
                }

                $current = in_array($item['id'], $selectParentIds);
                $url = $childList ? 'javascript:;' : url($item['url']);
                $addtabs = $childList || !$url ? "" : (stripos($url, "?") !== false ? "&" : "?") . "ref=addtabs";
                $childList = str_replace('" pid="' . $item['id'] . '"', ' treeview ' . ($current ? '' : 'hidden') . '" pid="' . $item['id'] . '"', $childList);
                $nav .= '<li class="' . ($current ? 'active' : '') . '"><a href="' . $url . $addtabs . '" addtabs="' . $item['id'] . '" url="' . $url . '"><i class="' . $item['icon'] . '"></i> <span>' . $item['title'] . '</span> <span class="pull-right-container"> </span></a> </li>';

            }
        }
        return [$menu, $nav, $selected, $referer];

大部分都是過濾組合，找到關鍵代碼

// 讀取用戶當前擁有的權限節點
$userRule = $this->getRuleList();

跳過去看看

    /**
     * 獲取會員組別規則菜單
     * @return array
     */
    public function getMenuList()
    {
        if ($this->menus) return $this->menus;
        $group = $this->_user->group;
        if (!$group) return [];
        $rules = explode(',', $group->rules);
        $this->menus = collection(UserRule::where('status', 'normal')->where('id', 'in', $rules)->where('ismenu', 1)
            ->order('weigh', 'desc')->select())->toArray();//->field('id,pid,name,title,ismenu,status,icon')
//        var_dump($this->menus);
//        exit;
        return $this->menus;
    }

在獲取的時候做了會員組的一個權限判斷，那應該就是權限的問題了。
