## API

* /apisix/plugin/wolf-rbac/change_pwd
* /apisix/plugin/wolf-rbac/user_info

You may need to use [interceptors](../plugin-interceptors.md) to protect it.

## Dependencies

### Install wolf and start the service

[Wolf quick start](https://github.com/iGeeky/wolf/blob/master/quick-start-with-docker/README.md)

### Add `application`, `admin`, `normal user`, `permission`, `resource` and user authorize

[Wolf-console usage](https://github.com/iGeeky/wolf/blob/master/docs/usage.md)


## How To Enable

1. set a consumer and config the value of the `wolf-rbac`。

```shell
curl http://127.0.0.1:9080/apisix/admin/consumers  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
  "username":"wolf_rbac",
  "plugins":{
    "wolf-rbac":{
      "server":"http://127.0.0.1:10080",
      "appid":"restful"
    }
  },
  "desc":"wolf-rbac"
}'
```

You can visit the dashboard: `http://127.0.0.1:9080/apisix/dashboard/`, to complete the above operations through the web interface, first add a consumer:
![](../images/plugin/wolf-rbac-1.png)

Then add the wolf-rbac plugin to the consumer page:
![](../images/plugin/wolf-rbac-2.png)

Notes: The `appid` filled in above needs to already exist in the wolf system.

1. Add a `Route` or `Service` and enable the wolf-rbac plugin.

```shell
curl http://127.0.0.1:9080/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
