但对于某些高级应用场景,还是需要添加自定义响应头: ```Python hl_lines="14" {!../../../docs_src/handling_errors/tutorial002.py!} ``` ## 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!} ```

**"404 Not Found"** のエラー(およびジョーク)を覚えていますか? ## `HTTPException`の使用 HTTPレスポンスをエラーでクライアントに返すには、`HTTPException`を使用します。 ### `HTTPException`のインポート ```Python hl_lines="1" {!../../../docs_src/handling_errors/tutorial001.py!} ``` ### コード内での`HTTPException`の発生 `HTTPException`は通常のPythonの例外であり、APIに関連するデータを追加したものです。 Pythonの例外なので、`return`ではなく、`raise`です。

### What is "Mounting" "Mounting" means adding a complete "independent" application in a specific path, that then takes care of handling all the sub-paths. This is different from using an `APIRouter` as a mounted application is completely independent. The OpenAPI and docs from your main application won't include anything from the mounted application, etc.

之后,所有处理逻辑都一样。 但因为改变了 `GzipRequest.body`,**FastAPI** 加载请求体时会自动解压。 ## 在异常处理器中访问请求体 !!! tip "提示" 为了解决同样的问题,在 `RequestValidationError` 的自定义处理器使用 `body` ([处理错误](../tutorial/handling-errors.md#use-the-requestvalidationerror-body){.internal-link target=_blank})可能会更容易。 但本例仍然可行,而且本例展示了如何与内部组件进行交互。 同样也可以在异常处理器中访问请求体。 此时要做的只是处理 `try`/`except` 中的请求: ```Python hl_lines="13 15"

#### Define a *path operation decorator* ```Python hl_lines="6" {!../../../docs_src/first_steps/tutorial001.py!} ``` The `@app.get("/")` tells **FastAPI** that the function right below is in charge of handling requests that go to: * the path `/` * using a <abbr title="an HTTP GET method"><code>get</code> operation</abbr> !!! info "`@decorator` Info" That `@something` syntax in Python is called a "decorator".

It is a plug-in for many frameworks (and there's a plug-in for Starlette too). The way it works is that you write the definition of the schema using YAML format inside the docstring of each function handling a route. And it generates OpenAPI schemas. That's how it works in Flask, Starlette, Responder, etc. But then, we have again the problem of having a micro-syntax, inside of a Python string (a big YAML).

## Accessing the request body in an exception handler !!! tip To solve this same problem, it's probably a lot easier to use the `body` in a custom handler for `RequestValidationError` ([Handling Errors](../tutorial/handling-errors.md#use-the-requestvalidationerror-body){.internal-link target=_blank}). But this example is still valid and it shows how to interact with the internal components.

You can import it directly form `fastapi`: ```python from fastapi import WebSocketDisconnect ``` ::: fastapi.WebSocketDisconnect ## WebSockets - additional classes Additional classes for handling WebSockets. Provided directly by Starlette, but you can import it from `fastapi`: ```python from fastapi.websockets import WebSocketDisconnect, WebSocketState ``` ::: fastapi.websockets.WebSocketDisconnect
