> NOTE: You can use the `-cscopes` parameter to restrict the requested scopes, for example to `"openid,policy_role_attribute"`, being `policy_role_attribute` a client_scope / client_mapper that maps a role attribute called policy to a `policy` claim returned by Keycloak.

claim_name    (string)    JWT canned policy claim name, defaults to "policy"
claim_prefix  (string)    JWT claim namespace prefix e.g. "customer1/"
scopes        (csv)       Comma separated list of OpenID scopes for server, defaults to advertised scopes from discovery document e.g. "email,admin"
comment       (sentence)  optionally add a comment to this setting
```

and ENV based options

/// tip | Dica

A coisa importante e "mágica" aqui é que `get_current_user` terá diferentes listas de `scopes` para validar para cada *operação de rota*.

## JWT-Token mit Scopes

Ändern Sie nun die Token-*Pfadoperation*, um die angeforderten Scopes zurückzugeben.

Wir verwenden immer noch dasselbe `OAuth2PasswordRequestForm`. Es enthält eine Eigenschaft `scopes` mit einer `list`e von `str`s für jeden Scope, den es im Request erhalten hat.

Und wir geben die Scopes als Teil des JWT-Tokens zurück.

	"istio.io/istio/pkg/log"

// Required to get global logging to work
var (
	CNIAgent  = log.RegisterScope(constants.CNIAgentLogScope, "CNI agent scope")
	CNIPlugin = log.RegisterScope(constants.CNIPluginLogScope, "CNI plugin scope")

For this, we use `security_scopes.scopes`, that contains a `list` with all these scopes as `str`.

## Dependency tree and scopes

Let's review again this dependency tree and the scopes.

                        * `security_scopes` 参数的属性 `scopes` 是包含上述声明的所有作用域的**列表**，因此：
                            * `security_scopes.scopes` 包含用于*路径操作*的 `["me", "items"]`
                            * `security_scopes.scopes` 包含*路径操作* `read_users_me` 的 `["me"]`，因为它在依赖项里被声明
                            * `security_scopes.scopes` 包含用于*路径操作* `read_system_status` 的 `[]`（空列表），并且它的依赖项 `get_current_user` 也没有声明任何 `scope`
