Denemek için:

* Uygulamayı birden fazla tarayıcı sekmesiyle açın.
* Bu sekmelerden mesaj yazın.
* Sonra sekmelerden birini kapatın.

Bu, `WebSocketDisconnect` exception'ını raise eder ve diğer tüm client'lar şuna benzer bir mesaj alır:

```
Client #1596980209979 left the chat

/// tip

And your **FastAPI** application might also be composed of several files/modules, etc.

### **FastAPI** app file { #fastapi-app-file }

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md):

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

In the file `main.py` you have your **FastAPI** app:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

[将 `dependencies` 添加到*路径操作装饰器*](dependencies-in-path-operation-decorators.md) 一章的思路均适用于全局依赖项， 在本例中，这些依赖项可以用于应用中的所有*路径操作*。

## 为一组路径操作定义依赖项 { #dependencies-for-groups-of-path-operations }

        if (testToken != null) {
            logger.info("Token: {}", testToken);
            return testToken;
        }

        given().contentType("application/json")
                .body("{\"index\":{\"_index\":\"fess_config.access_token\",\"_id\":\"" + DEFAULT_TEST_TOKEN_ID

Örneğin Uvicorn'u kurmak için:

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

</div>

Benzer bir süreç, diğer ASGI server programlarının tamamı için de geçerlidir.

/// tip | İpucu

`standard` eklediğinizde Uvicorn, önerilen bazı ek bağımlılıkları kurar ve kullanır.

而且，在[將 `dependencies` 新增到路徑操作裝飾器](dependencies-in-path-operation-decorators.md) 那一節中的所有概念依然適用，只是這裡是套用到整個應用中的所有路徑操作。

## 路徑操作群組的依賴 { #dependencies-for-groups-of-path-operations }
