Quando você cria uma aplicação com o **FastAPI**, existe um atributo chamado `webhooks`, que você utilizar para defini-los da mesma maneira que você definiria as suas **operações de rotas**, utilizando por exemplo `@app.webhooks.post()`.

```Python hl_lines="9-13  36-53"
{!../../docs_src/openapi_webhooks/tutorial001.py!}
```

Os webhooks que você define aparecerão no esquema do **OpenAPI** e na **página de documentação** gerada automaticamente.

Но при просмотре и сравнении замеров производительности следует иметь в виду нижеописанное.

#### Option B: Paste your code here or provide a link to a custom end-to-end colab

```
(You can paste links or attach files by dragging & dropping them below)
- Include code to invoke the TFLite Converter Python API and the errors.
- Provide links to your TensorFlow model and (optionally) TensorFlow Lite Model.
```

### 3. Failure after conversion

不过，仍可以验证、转换与注释（使用 Pydantic 模型的请求体等）其它正常声明的参数。

但在某些特定情况下，还是需要提取 `Request` 对象。

## 直接使用 `Request` 对象

假设要在*路径操作函数*中获取客户端 IP 地址和主机。

此时，需要直接访问请求。

```Python hl_lines="1  7-8"
{!../../docs_src/using_request_directly/tutorial001.py!}
```

把*路径操作函数*的参数类型声明为 `Request`，**FastAPI** 就能把 `Request` 传递到参数里。

/// tip | "提示"

注意，本例除了声明请求参数之外，还声明了路径参数。

Sehingga kamu dapat kembali lagi dan mencari apa yang kamu butuhkan dengan tepat.

## Jalankan kode

Semua blok-blok kode dapat disalin dan digunakan langsung (Mereka semua sebenarnya adalah file python yang sudah teruji).

Untuk menjalankan setiap contoh, salin kode ke file `main.py`, dan jalankan `uvicorn` dengan:

<div class="termy">

```console
$ uvicorn main:app --reload

Beim Ansehen von Benchmarks und Vergleichen sollten Sie jedoch Folgende Punkte beachten.
