## Healthcheck Probe

MinIO server has two healthcheck related un-authenticated endpoints, a liveness probe to indicate if server is responding, cluster probe to check if server can be taken down for maintenance.

- Liveness probe available at `/minio/health/live`
- Cluster probe available at `/minio/health/cluster`

```

Examples:

Source (English):

```
<abbr title="JSON Web Tokens">JWT</abbr>
<abbr title="Enumeration">Enum</abbr>
<abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>
```

Result (German):

```
<abbr title="JSON Web Tokens">JWT</abbr>
<abbr title="Enumeration">Enum</abbr>
<abbr title="Asynchrones Server-Gateway-Interface">ASGI</abbr>
```

Tiene una operación `GET` que podría devolver un error.

Tiene una operación `POST` que podría devolver varios errores.

Ambas *path operations* requieren un `X-Token` header.

{* ../../docs_src/app_testing/app_b_an_py310/main.py *}

### Archivo de prueba extendido { #extended-testing-file }

Podrías entonces actualizar `test_main.py` con las pruebas extendidas:

В нём описана операция `GET`, которая может вернуть ошибку.

Ещё есть операция `POST`, и она может вернуть несколько ошибок.

Обе *операции пути* требуют наличия в запросе HTTP-заголовка `X-Token`.

{* ../../docs_src/app_testing/app_b_an_py310/main.py *}

### Расширенный файл тестов { #extended-testing-file }

Теперь обновим файл `test_main.py`, добавив в него тестов:

pkg go/ast, func PackageExports //deprecated #73088
pkg go/ast, func PreorderStack(Node, []Node, func(Node, []Node) bool) #73319
pkg go/ast, type MergeMode //deprecated #73088
pkg go/parser, func ParseDir //deprecated #71122
pkg go/token, method (*FileSet) AddExistingFiles(...*File) #73205
pkg go/types, const FieldVar = 6 #70250
pkg go/types, const FieldVar VarKind #70250
pkg go/types, const LocalVar = 2 #70250
pkg go/types, const LocalVar VarKind #70250

metrics without authentication, you don't need to use `mc` to generate prometheus config. You can skip reading further and move to 3.2 section.

The Prometheus endpoint in MinIO requires authentication by default. Prometheus supports a bearer token approach to authenticate prometheus scrape requests, override the default Prometheus config with the one generated using mc. To generate a Prometheus config for an alias, use [mc](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart)...

我們稍後會把這個 `APIRouter` 加進主要的 `FastAPI` 應用程式中，但先來看看相依性與另一個 `APIRouter`。

## 相依性 { #dependencies }

我們發現應用程式的多個地方會用到一些相依性。

所以把它們放進獨立的 `dependencies` 模組（`app/dependencies.py`）。

接下來我們會用一個簡單的相依性來讀取自訂的 `X-Token` 標頭：

{* ../../docs_src/bigger_applications/app_an_py310/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | 提示

為了簡化範例，我們使用了一個虛構的標頭。

但在真實情況下，使用內建的 [安全工具](security/index.md) 會有更好的效果。
