* 权限认证类

* $auth = new \taoser\think\Auth(); $auth->check('规则名称','用户id')
* 2，可以同时对多条规则进行认证，并设置多条规则的关系（or或者and）
* $auth = new \taoser\think\Auth(); $auth->check('规则1,规则2','用户id','and')
* 第三个参数为and时表示，用户需要同时具有规则1和规则2的权限。 当第三个参数为or时，表示用户值需要具备其中一个条件即可。默认为or
* 3，一个用户可以属于多个用户组(tp_auth_group_access表 定义了用户所属用户组)。我们需要设置每个用户组拥有哪些规则(tp_auth_group 定义了用户组权限)
*
* 4，支持规则表达式。
* 在tp_auth_rule 表中定义一条规则时，如果type为1， condition字段就可以定义规则表达式。 如定义{score}>5 and {score}<100 表示用户的分数在5-100之间时这条规则才会通过。

## 原理
Auth权限认证是按规则进行认证。
在数据库中我们有
- 规则表（think_auth_rule）
- 用户组表(think_auth_group)
- 用户组明显表（think_auth_group_access）
我们在规则表中定义权限规则， 在用户组表中定义每个用户组有哪些权限规则，在用户组明显表中定义用户所属的用户组。
//命名空间为
namespace taoser\think;
//直接使用
$auth = new \taoser\think\Auth();
// 引入类库
use think\auth\Auth;
$auth = new Auth();
// 检测权限
if($auth->check('show_button',1)){// 第一个参数是规则名称,第二个参数是用户UID
//有显示操作按钮的权限
}else{
//没有显示操作按钮的权限
}
## 实例
~~~php
//以下实例以thinkphp5.1为例说明
Auth类也可以对节点进行认证，我们只要将规则名称，定义为节点名称就行了。
可以在公共控制器Base中定义_initialize方法
~~~
~~~php
<?php
//简单实例
namespace app\admin\controller;
use app\BaseController;
use think\auth\Auth;
class Base extends BaseController
{
public function initialize()
{
if (!session('admin_id')) {
$this->redirect('login/index');
}
$auth = new Auth();
$controller = strtolower(request()->controller());
$action = strtolower(request()->action());
$url = $controller . "/" . $action;
if (!$auth->check($url, session('admin_id'))) {
$this->error('抱歉，您没有操作权限');
}
}
}
~~~
~~~php
<?php
//高级实例 根据用户积分判断权限
//Auth类还可以按用户属性进行判断权限， 比如 按照用户积分进行判断，假设我们的用户表 (tp_admin) 有字段 score 记录了用户积分。我在规则表添加规则时，定义规则表的condition 字段，condition字段是规则条件，默认为空 表示没有附加条件，用户组中只有规则 就通过认证。如果定义了 condition字段，用户组中有规则不一定能通过认证，程序还会判断是否满足附加条件。 比如我们添加几条规则：
//name字段：grade1 condition字段：{score}<100
//name字段：grade2 condition字段：{score}>100 and {score}<200
//name字段：grade3 condition字段：{score}>200 and {score}<300
//这里 {score} 表示 think_members 表 中字段 score 的值。
//那么这时候
$auth = new \taoser\think\Auth();
$auth->check('grade1', 1); //是判断用户积分是不是0-100
$auth->check('grade2', 1); //判断用户积分是不是在100-200
$auth->check('grade3', 1); //判断用户积分是不是在200-300
~~~
~~~php
<?php
//高级实例 右侧菜单根据权限隐藏实例
namespace app\admin\controller;
use think\Controller;
use think\Db;
class Base extends Controller
{
public function initialize()
{
if (!session('admin_id')) {
$this->redirect('login/index');
}
$auth = new \taoser\think\Auth();
$controller = strtolower(request()->controller());
$action = strtolower(request()->action());
$url = $controller . "/" . $action;
$data = Db::name('auth_rule')->order('sort','asc')->select();
$data = list_to_tree($data);
//排除不需要验证的规则
$no_check_default = ['index/index'];
$no_check_status_list = Db::name('auth_rule')->where('status', 0)->column('name');
$no_check_rules_list = explode(',', strtolower(implode(',', array_merge($no_check_default, (array)$no_check_status_list))));
$no_check_user_list = Db::name('admin')->where('is_admin', 1)->column('id');
if (!in_array(session('admin_id'), $no_check_user_list)) {
if (!in_array($url, $no_check_rules_list)) {
if (!$auth->check($url, session('admin_id'))) {
$this->error('抱歉，您没有操作权限');
}
}
foreach ($data as $k => $v) {
if (!$auth->check($v['name'], session('admin_id'))) {
unset($data[$k]);
} else {
if (isset($v['_child'])) {
foreach ($v['_child'] as $key => $value) {
if (!$auth->check($value['name'], session('admin_id'))) {
unset($data[$k]['_child'][$key]);
}
}
}
}
}
}
//unset($data[0]['_child'][0]);
//var_dump($data);
//mysql不区分字段内容大小写
$active_id = Db::name('auth_rule')->where('name', '=', $url)->field('id,pid,top_pid')->find();
$this->assign([
'active_id' => implode(',', (array)$active_id),
'menu_nav' => $data,
'crumb_list' => get_crumb_list($url)
]);
}
}
