2、casbin介绍和使用

casbin如果看不懂，可以学习基础语法

需要学习casbin的详细理解过程（附图片理解）（rbac模型）-CSDN博客

2.1基本知识：

r = sub, obj, act

意思：请求入参（实体，资源，方法）

p = sub, obj, act

意思：策略（实体，资源，方法）

g = _ , _

意思：角色权限，这里的意思是g收到两个参数 g = 用户，角色

2.2使用例子

"policy": "p,GRANT_ROLE_firstconsumer,/dcpyo/test, *\ng,firstconsumer,GRANT_ROLE_firstconsumer\np,GRANT_ROLE_11120150115,/dcpyo/test, *\ng,11120150115,GRANT_ROLE_11120150115\n",

"username": "appKey"

policy的意思是：

p,GRANT_ROLE_firstconsumer,/dcpyo/test, *

意思：策略GRANT_ROLE_firstconsumer有接口/dcpyo/test的所有权限

g,firstconsumer,GRANT_ROLE_firstconsumer

意思：用户firstconsumer有权限GRANT_ROLE_firstconsumer

3、配置插件

auth-caszbin username可以指定头的别名

配置一个路由例子：

{

"uri": "/dcpyo/test",

"name": "4种认证20250113",

"desc": "4种认证20250113",

"plugins": {

"authz-casbin": {

"model": " [request_definition] \n r = sub, obj, act \n [policy_definition] \n p = sub, obj, act \n [role_definition] \n g = _, _ \n [policy_effect] \n e = some(where (p.eft == allow)) \n [matchers] \n m = (g(r.sub, p.sub) || keyMatch(r.sub, p.sub)) && keyMatch(r.obj, p.obj) && keyMatch(r.act, p.act) ",

"policy": "p,GRANT_ROLE_firstconsumer,/dcpyo/test, *\ng,firstconsumer,GRANT_ROLE_firstconsumer\np,GRANT_ROLE_11120150115,/dcpyo/test, *\ng,11120150115,GRANT_ROLE_11120150115\n",

"username": "appKey"

"proxy-rewrite": {

}
