### **FastAPI** Normal { #normal-fastapi }

Primeiro, escreva toda a sua aplicação **FastAPI** normalmente:

     * @return the parent lease key
     */
    public Smb2LeaseKey getParentLeaseKey() {
        return parentLeaseKey;
    }

    /**
     * Gets the lease epoch from the V2 response
     * @return the epoch
     */
    public int getEpoch() {
        return epoch;
    }

    @Override
    public int decode(byte[] buffer, int bufferIndex, int len) throws SMBProtocolDecodingException {
        int start = bufferIndex;

Vous verrez la documentation automatique alternative (fournie par <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>) :

### 可选的 API 文档

访问 <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>。

你会看到另一个自动生成的文档（由 <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a> 生成）：

## 示例升级

现在修改 `main.py` 文件来从 `PUT` 请求中接收请求体。

Y **ReDoc** utiliza el archivo:

* <a href="https://cdn.jsdelivr.net/npm/redoc@2/bundles/redoc.standalone.js" class="external-link" target="_blank">`redoc.standalone.js`</a>

Después de eso, tu estructura de archivos podría verse así:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
└── static
    ├── redoc.standalone.js
    ├── swagger-ui-bundle.js

E o **ReDoc** usa o arquivo:

* <a href="https://cdn.jsdelivr.net/npm/redoc@2/bundles/redoc.standalone.js" class="external-link" target="_blank">`redoc.standalone.js`</a>

Depois disso, sua estrutura de arquivos deve se parecer com:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
└── static
    ├── redoc.standalone.js
    ├── swagger-ui-bundle.js

Используя информацию выше, вы можете той же вспомогательной функцией сгенерировать схему OpenAPI и переопределить любые нужные части.

Например, добавим <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" class="external-link" target="_blank">расширение OpenAPI ReDoc для включения собственного логотипа</a>.

### Обычный **FastAPI** { #normal-fastapi }

Сначала напишите приложение **FastAPI** как обычно:
