比如，下面有 4 个 API 路径操作（*端点*）：

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

开发人员可以使用依赖项及其子依赖项为这些路径操作添加不同的权限：

```mermaid
graph TB

current_user(["current_user"])
active_user(["active_user"])
admin_user(["admin_user"])
paying_user(["paying_user"])

public["/items/public/"]
private["/items/private/"]

                                }
                            },
                        },
                    },
                    "summary": "Read Item Public Data",
                    "operationId": "read_item_public_data_items__item_id__public_get",
                    "parameters": [
                        {
                            "required": True,

例えば、４つのAPIエンドポイント（*path operations*）があるとします:

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

そして、依存関係とサブ依存関係だけで、それぞれに異なるパーミッション要件を追加することができます:

```mermaid
graph TB

current_user(["current_user"])
active_user(["active_user"])
admin_user(["admin_user"])
paying_user(["paying_user"])

public["/items/public/"]
private["/items/private/"]

                                }
                            },
                        },
                    },
                    "summary": "Read Item Public Data",
                    "operationId": "read_item_public_data_items__item_id__public_get",
                    "parameters": [
                        {
                            "required": True,

                                }
                            },
                        },
                    },
                    "summary": "Read Item Public Data",
                    "operationId": "read_item_public_data_items__item_id__public_get",
                    "parameters": [
                        {
                            "required": True,
