У цьому прикладі вона конвертує Pydantic model у `dict`, а `datetime` у `str`.

Nesse caso, significaria os atributos JSON e os tipos de dados que eles possuem, etc.

#### OpenAPI e JSON Schema { #openapi-and-json-schema }

OpenAPI define um *schema* de API para sua API. E esse *schema* inclui definições (ou "*schemas*") dos dados enviados e recebidos por sua API usando **JSON Schema**, o padrão para *schemas* de dados JSON.

En ese caso, significaría los atributos del JSON, los tipos de datos que tienen, etc.

#### OpenAPI y JSON Schema { #openapi-and-json-schema }

OpenAPI define un esquema de API para tu API. Y ese esquema incluye definiciones (o "esquemas") de los datos enviados y recibidos por tu API utilizando **JSON Schema**, el estándar para esquemas de datos JSON.

def test_main():
    response = client.get("/app")
    assert response.status_code == 200
    assert response.json() == {"message": "Hello World", "root_path": "/api/v1"}


def test_openapi():
    response = client.get("/openapi.json")
    assert response.status_code == 200
    assert response.json() == {

#### 資料 「schema」

「schema」這個術語也可能指某些資料的結構，比如 JSON 內容的結構。

在這種情況下，它指的是 JSON 的屬性、資料型別等。

#### OpenAPI 和 JSON Schema

OpenAPI 定義了 API 的 schema。這個 schema 包含了使用 **JSON Schema** 定義的資料，這是 JSON 資料 schema 的標準。

#### 檢查 `openapi.json`

如果你好奇原始的 OpenAPI schema 長什麼樣子，FastAPI 會自動生成一個包含所有 API 描述的 JSON (schema)。

    response = client.post("/pet/assignment", json={"pet_type": "cat", "meows": 5})
    assert response.status_code == 200, response.text
    assert response.json() == {"pet_type": "cat", "meows": 5}


def test_union_body_discriminator_annotated(client: TestClient) -> None:
    response = client.post("/pet/annotated", json={"pet_type": "dog", "barks": 3.5})
    assert response.status_code == 200, response.text
