我们还可以添加一个 `tags` 列表和额外的 `responses` 列表，这些参数将应用于此路由器中包含的所有*路径操作*。

我们可以添加一个 `dependencies` 列表，这些依赖项将被添加到路由器中的所有*路径操作*中，并将针对向它们发起的每个请求执行/解决。

请注意，和[*路径操作装饰器*中的依赖项](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}很类似，没有值会被传递给你的*路径操作函数*。

最终结果是项目相关的路径现在为：

...如我们所愿。

La façon dont vous l'utilisez est très simple. Par exemple, pour faire une requête `GET`, vous devez écrire :

```Python
response = requests.get("http://example.com/some/url")
```

En contrepartie l'API _des opérations de chemin_ de FastAPI pourrait ressembler à ceci :

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

}

// AuthNErrorResponse - represents an error response from the authN plugin.
type AuthNErrorResponse struct {
	Reason string `json:"reason"`
}

// AuthNResponse - represents a result of the authentication operation.
type AuthNResponse struct {
	Success *AuthNSuccessResponse
	Failure *AuthNErrorResponse
}

const (
	minValidityDurationSeconds int = 900
	maxValidityDurationSeconds int = 365 * 24 * 3600
)
