* Do not finish the title with a period (`.`).
* When the PR is for a translation, start with the `🌐` and then `Add {language} translation for` and then the translated file path. For example:

```Markdown
🌐 Add Spanish translation for `docs/es/docs/teleporting.md`
```

执行顺序大致如下时序图所示。时间轴从上到下，每一列都代表交互或者代码执行的一部分。

participant client as Client
participant handler as Exception handler
participant dep as Dep with yield
participant operation as Path Operation
participant tasks as Background tasks

    Note over client,operation: Can raise exceptions, including HTTPException
    client ->> dep: Start request
    Note over dep: Run code up to yield

### `FileResponse`

Streamt eine Datei asynchron als Response.

Nimmt zur Instanziierung einen anderen Satz von Argumenten entgegen als die anderen Response-Typen:

* `path` – Der Dateipfad zur Datei, die gestreamt werden soll.
* `headers` – Alle benutzerdefinierten Header, die inkludiert werden sollen, als Dictionary.

/// tip

Prefer to use the `Annotated` version if possible.

## Update the `/token` *path operation*

Create a `timedelta` with the expiration time of the token.

Create a real JWT access token and return it.

/// tip

We'll discuss the `@lru_cache` in a bit.

For now you can assume `get_settings()` is a normal function.

///

And then we can require it from the *path operation function* as a dependency and use it anywhere we need it.

* Paths containing backsteps (for example, "../bar") are no longer allowed in hostPath volume paths, or in volumeMount subpaths ([#47290](https://github.com/kubernetes/kubernetes/pull/47290), [@jhorwit2](https://github.com/jhorwit2))

In Kubernetes 1.18, there are two significant additions to Ingress: A new `pathType` field and a new `IngressClass` resource. The `pathType` field allows specifying how paths should be matched. In addition to the default `ImplementationSpecific` type, there are new `Exact` and `Prefix` path types.
