beego-authz 
beego-authz is an authorization middleware for Beego. It provides authorization like ACL, RBAC, ABAC based on Casbin: https://github.com/casbin/casbin
With beego-authz, you can control who can access what resource via which method for your Beego app.
Get Started
Step 1: edit the policy
Modify the Casbin model: authz_model.conf and policy: authz_policy.csv as you want. You may need to learn Casbin's basics to know how to edit these files. The policy means that the user alice can access /dataset1/* via GET and /dataset1/resource1 via POST. The similar way applies to user bob. cathy has the role dataset1_admin, which is permitted to access any resources under /dataset1/ with any action. For more advanced usage of Casbin (like database support, policy language grammar, etc), please refer to Casbin: https://github.com/casbin/casbin
Step 2: integrate with Beego
Insert the Casbin authorizer as a Beego filter.
beego.InsertFilter("*", beego.BeforeRouter, authz.NewAuthorizer(casbin.NewEnforcer("authz_model.conf", "authz_policy.csv")))
Step 3: setup with authentication
Make sure you already have an authentication mechanism, so you know who is accessing, like a username. Modify the GetUserName() method to let Casbin know the current authenticated username.
