Se você não declarar um modelo de resposta, o FastAPI usará o `jsonable_encoder` explicado em [Codificador Compatível com JSON](../tutorial/encoder.md) e o colocará em uma `JSONResponse`.

Você também pode criar uma `JSONResponse` diretamente e retorná-la.

## Convert any Data to JSON-compatible { #convert-any-data-to-json-compatible }

To convert any data to JSON-compatible, read the docs for [Tutorial - JSON Compatible Encoder](../tutorial/encoder.md).

## OpenAPI Metadata - Docs { #openapi-metadata-docs }

Якщо ви не оголошуєте модель відповіді, **FastAPI** використає `jsonable_encoder`, описаний у [Сумісному з JSON кодері](../tutorial/encoder.md), і помістить результат у `JSONResponse`.

Ви також можете створити `JSONResponse` безпосередньо і повернути його.

/// tip | Порада

from fastapi import FastAPI
from fastapi.encoders import jsonable_encoder
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str | None = None
    description: str | None = None
    price: float | None = None
    tax: float = 10.5
    tags: list[str] = []


items = {
    "foo": {"name": "Foo", "price": 50.2},
    "bar": {"name": "Bar", "description": "The bartenders", "price": 62, "tax": 20.2},

关于如何传数据给后端的更多信息（使用 `httpx` 或 `TestClient`），请查阅 [HTTPX 文档](https://www.python-httpx.org)。

/// info | 信息

注意 `TestClient` 接收可以被转化为JSON的数据，而不是Pydantic模型。

如果你在测试中有一个Pydantic模型，并且你想在测试时发送它的数据给应用，你可以使用在[JSON Compatible Encoder](encoder.md)介绍的`jsonable_encoder` 。

///

## 运行起来 { #run-it }

之后，你只需要安装 `pytest`。

确保你创建并激活一个[虚拟环境](../virtual-environments.md)，然后再安装，例如：

<div class="termy">

```console

`TestClient`'ın Pydantic model'lerini değil, JSON'a dönüştürülebilen verileri aldığını unutmayın.

Testinizde bir Pydantic model'iniz varsa ve test sırasında verisini uygulamaya göndermek istiyorsanız, [JSON Uyumlu Encoder](encoder.md) içinde açıklanan `jsonable_encoder`'ı kullanabilirsiniz.

///

## Çalıştırma { #run-it }

Bundan sonra yapmanız gereken tek şey `pytest`'i kurmaktır.
