## 名字
`wolf-rbac` 是一个认证及授权(rbac)插件,它需要与 `consumer` 一起配合才能工作。同时需要添加 `wolf-rbac` 到一个 `service``route` 中。
rbac功能由[wolf](https://github.com/iGeeky/wolf)提供, 有关 `wolf` 的更多信息, 请参考[wolf文档](https://github.com/iGeeky/wolf)。
## 属性
* `server`: 设置 `wolf-server` 的访问地址, 如果未设置, 默认为: `http://127.0.0.1:10080`.
* `appid`: 设置应用id, 该应用id, 需要是在 `wolf-console` 中已经添加的应用id.
* `header_prefix`: 自定义http头的前缀, 默认为: `X-`. `wolf-rbac`在鉴权成功后, 会在请求头(用于传给后端)及响应头(用于传给前端)中添加3个头: `X-UserId`, `X-Username`, `X-Nickname`.

## 依赖项
### 安装 wolf, 并启动服务
[Wolf快速起步](https://github.com/iGeeky/wolf/blob/master/quick-start-with-docker/README-CN.md)
### 添加应用, 管理员, 普通用户, 权限, 资源 及给用户授权.
[Wolf管理使用](https://github.com/iGeeky/wolf/blob/master/docs/usage.md)
## 如何启用
1. 创建一个 consumer 对象,并设置插件 `wolf-rbac` 的值。
```shell
curl http://127.0.0.1:9080/apisix/admin/consumers -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
2020-02-06 15:22:49 +08:00
{
"username":"wolf_rbac",
"plugins":{
"wolf-rbac":{
"server":"http://127.0.0.1:10080",
"appid":"restful"
}
},
"desc":"wolf-rbac"
}'
```
你可以使用浏览器打开 dashboard`http://127.0.0.1:9080/apisix/dashboard/`,通过 web 界面来完成上面的操作,先增加一个 consumer

注意: 上面填写的 `appid` 需要在wolf控制台中已经存在的.
2. 创建 Route 或 Service 对象,并开启 `wolf-rbac` 插件。
```shell
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '

## 测试插件
#### 首先进行登录获取 `wolf-rbac` token:
下面的 `appid`, `username`, `password` 必须为wolf系统中真实存在的.
* 以POST application/json方式登陆.
```shell
curl http://127.0.0.1:9080/apisix/plugin/wolf-rbac/login -i \
-H "Content-Type: application/json" \
-d '{"appid": "restful", "username":"test", "password":"user-password"}'
