/**
|
|
* 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(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 表中定义一条规则，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。
