  2. docs/zh/docs/tutorial/handling-errors.md

    添加自定义处理器,要使用 [Starlette 的异常工具](https://www.starlette.io/exceptions/)。
    
    假设要触发的自定义异常叫作 `UnicornException`。
    
    且需要 FastAPI 实现全局处理该异常。
    
    此时,可以用 `@app.exception_handler()` 添加自定义异常控制器:
    
    ```Python hl_lines="5-7  13-18  24"
    {!../../../docs_src/handling_errors/tutorial003.py!}
    
    ```
    
    请求 `/unicorns/yolo` 时,路径操作会触发 `UnicornException`。
    
    但该异常将会被 `unicorn_exception_handler` 处理。
    
    接收到的错误信息清晰明了,HTTP 状态码为 `418`,JSON 内容如下:

    ## カスタム例外ハンドラのインストール
    
    カスタム例外ハンドラは<a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">Starletteと同じ例外ユーティリティ</a>を使用して追加することができます。
    
    あなた(または使用しているライブラリ)が`raise`するかもしれないカスタム例外`UnicornException`があるとしましょう。
    
    そして、この例外をFastAPIでグローバルに処理したいと思います。
    
    カスタム例外ハンドラを`@app.exception_handler()`で追加することができます:
    
    ```Python hl_lines="5 6 7  13 14 15 16 17 18  24"

  7. docs/en/docs/advanced/middleware.md

    app = SomeASGIApp()
    
    new_app = UnicornMiddleware(app, some_config="rainbow")
    ```
    
    But FastAPI (actually Starlette) provides a simpler way to do it that makes sure that the internal middlewares to handle server errors and custom exception handlers work properly.
    
    For that, you use `app.add_middleware()` (as in the example for CORS).
    
    ```Python
    from fastapi import FastAPI
    from unicorn import UnicornMiddleware
    
    app = FastAPI()

  8. docs/en/docs/how-to/custom-request-and-route.md

    We can also use this same approach to access the request body in an exception handler.
    
    All we need to do is handle the request inside a `try`/`except` block:
    
    ```Python hl_lines="13  15"
    {!../../../docs_src/custom_request_and_route/tutorial002.py!}
    ```
    
    If an exception occurs, the`Request` instance will still be in scope, so we can read and make use of the request body when handling the error:

                - close
    
    When a client disconnects, a `WebSocketDisconnect` exception is raised, you can catch it.
    
    You can import it directly form `fastapi`:
    
    ```python
    from fastapi import WebSocketDisconnect
    ```
    
    ::: fastapi.WebSocketDisconnect

  10. docs/de/docs/tutorial/handling-errors.md

    Nehmen wir an, Sie haben eine benutzerdefinierte Exception `UnicornException`, die Sie (oder eine Bibliothek, die Sie verwenden) `raise`n könnten.
    
    Und Sie möchten diese Exception global mit FastAPI handhaben.
