    Convert any object to something that can be encoded in JSON.

    This is used internally by FastAPI to make sure anything you return can be
    encoded as JSON before it is sent to the client.

這裡我們宣告 `openapi_url` 設定，預設值同樣是 `"/openapi.json"`。

接著在建立 `FastAPI` 應用時使用它。

然後你可以將環境變數 `OPENAPI_URL` 設為空字串，以停用 OpenAPI（包含文件 UI），如下：

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

之後若你造訪 `/openapi.json`、`/docs` 或 `/redoc`，會看到如下的 `404 Not Found` 錯誤：

```JSON

Eles serão convertidos para seus valores correspondentes (strings neste caso) antes de serem retornados ao cliente:

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

No seu cliente, você receberá uma resposta JSON como:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}

使用 `ModelName.lenet.value` 也能获取值 `"lenet"`。

///

#### 返回枚举成员 { #return-enumeration-members }

即使嵌套在 JSON 请求体里（例如，`dict`），也可以从路径操作返回枚举成员。

返回给客户端之前，会把枚举成员转换为对应的值（本例中为字符串）：

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

客户端中的 JSON 响应如下：

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

        |  -H 'Content-Type: application/json; charset=utf-8' \
        |  --data '{"key":"value"}'
        """.trimMargin(),
      )
  }

## What is "Form Data" { #what-is-form-data }

The way HTML forms (`<form></form>`) sends the data to the server normally uses a "special" encoding for that data, it's different from JSON.

**FastAPI** will make sure to read that data from the right place instead of JSON.

/// note | Technical Details

Data from forms is normally encoded using the "media type" `application/x-www-form-urlencoded` when it doesn't include files.

O jeito que os formulários HTML (`<form></form>`) enviam os dados para o servidor normalmente usa uma codificação "especial" para esses dados, a qual é diferente do JSON.

**FastAPI** se certificará de ler esses dados do lugar certo, ao invés de JSON.

/// note | Detalhes Técnicos

Dados de formulários normalmente são codificados usando o "media type" `application/x-www-form-urlencoded` quando não incluem arquivos.
