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

    Und bietet auch einen Default-Exceptionhandler dafür.
    
    Um diesen zu überschreiben, importieren Sie den `RequestValidationError` und verwenden Sie ihn in `@app.exception_handler(RequestValidationError)`, um Ihren Exceptionhandler zu dekorieren.
    
    Der Exceptionhandler wird einen `Request` und die Exception entgegennehmen.

  4. docs/en/docs/tutorial/handling-errors.md

    Let's say you have a custom exception `UnicornException` that you (or a library you use) might `raise`.
    
    And you want to handle this exception globally with FastAPI.
    
    You could add a custom exception handler with `@app.exception_handler()`:
    
    ```Python hl_lines="5-7  13-18  24"
    {!../../docs_src/handling_errors/tutorial003.py!}
    ```
    
    Here, if you request `/unicorns/yolo`, the *path operation* will `raise` a `UnicornException`.

  5. docs/ru/docs/tutorial/handling-errors.md

    И вы хотите обрабатывать это исключение глобально с помощью FastAPI.
    
    Можно добавить собственный обработчик исключений с помощью `@app.exception_handler()`:
    
    ```Python hl_lines="5-7  13-18  24"
    {!../../docs_src/handling_errors/tutorial003.py!}
    ```
    
    Здесь, если запросить `/unicorns/yolo`, то *операция пути* вызовет `UnicornException`.

  6. docs/pt/docs/tutorial/handling-errors.md

    Nesse cenário, se você precisa manipular essa exceção de modo global com o FastAPI, você pode adicionar um manipulador de exceção customizada com `@app.exception_handler()`.
    
    ```Python hl_lines="5-7  13-18  24"
    {!../../docs_src/handling_errors/tutorial003.py!}
    ```

  7. docs/ja/docs/tutorial/handling-errors.md

    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"
    {!../../docs_src/handling_errors/tutorial003.py!}
    ```
    
    ここで、`/unicorns/yolo`をリクエストすると、*path operation*は`UnicornException`を`raise`します。

    ## 安装自定义异常处理器
    
    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`。
