This article describes the thinkPHP5 framework auth permission control class as an example. Share it for your reference, as follows:
This is a simpler usage:
Directly post the class, here I changed, I did not use uid, because I built the table is admin table, so the corresponding query in the code changed to aid
And the table name, I have removed the prefix

/**
* 权限认证类
* 功能特性：
* 1，是对规则进行认证，不是对节点进行认证。用户可以把节点当作规则名称实现对节点进行认证。
* $auth=new 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 Auth(); $auth->check('规则1,规则2','用户id','and')
* 第3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3个参数为or时，表示用户值需要具备其中1个条件即可。默认为or
* 3，1个用户可以属于多个用户组(think_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(think_auth_group 定义了用户组权限)
*
* 4，支持规则表达式。
* 在think_auth_rule 表中定义1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。

Auth. php is placed under extend in the auth directory with the namespace auth
Then use the constructor in the controller used, or inherit a controller that uses the constructor as follows:
public function _initialize()
{
$aid = 1;
$auth = new \auth\Auth();
$request = Request::instance();
$au = $auth->check($request->module() . '/' . $request->controller() . '/' . $request->action(), $aid);
if (!$au) {// No. 1 1 Parameters are rule names , No. 1 2 Parameters are users UID
/* return array('status'=>'error','msg'=>' Have permission! ');*/
$this->error(' You don't have access ');
}
}
The above $aid should be obtained after the user logs in, and normally it should be
session()
Obtained user id
The relevant business logic can be judged by oneself, and the rest is to add the whole county, add the user group, and so on.
