Il s'agit d'un projet de la Fondation Linux. Il fournit des certificats HTTPS gratuitement. De manière automatisée. Ces certificats utilisent toutes les sécurités cryptographiques standard et ont une durée de vie courte (environ 3 mois), de sorte que la sécurité est en fait meilleure en raison de leur durée de vie réduite.

@app.get("/items/valid", response_model=Item)
def get_valid():
    return {"name": "valid", "price": 1.0}


@app.get("/items/coerce", response_model=Item)
def get_coerce():
    return {"name": "coerce", "price": "1.0"}


@app.get("/items/validlist", response_model=List[Item])
def get_validlist():
    return [
        {"name": "foo"},
        {"name": "bar", "price": 1.0},

So, even with the code above that doesn't use Pydantic explicitly, FastAPI is using Pydantic to convert those standard dataclasses to Pydantic's own flavor of dataclasses.

And of course, it supports the same:

* data validation
* data serialization
* data documentation, etc.

This works the same way as with Pydantic models. And it is actually achieved in the same way underneath, using Pydantic.

```Python hl_lines="8-15"

```

### 创建自定义 `GzipRoute` 类

接下来，创建使用 `GzipRequest` 的 `fastapi.routing.APIRoute  ` 的自定义子类。

此时，这个自定义子类会覆盖 `APIRoute.get_route_handler()`。

`APIRoute.get_route_handler()` 方法返回的是函数，并且返回的函数接收请求并返回响应。

本例用它根据原始请求创建 `GzipRequest`。

```Python hl_lines="18-26"
{!../../../docs_src/custom_request_and_route/tutorial001.py!}
```

!!! note "技术细节"

from fastapi.testclient import TestClient
from starlette.routing import Route

app = FastAPI()


class APIRouteA(APIRoute):
    x_type = "A"


class APIRouteB(APIRoute):
    x_type = "B"


class APIRouteC(APIRoute):
    x_type = "C"


router_a = APIRouter(route_class=APIRouteA)
router_b = APIRouter(route_class=APIRouteB)
router_c = APIRouter(route_class=APIRouteC)


@router_a.get("/")
def get_a():

We get the same response:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

but this time at the URL with the prefix path provided by the proxy: `/api/v1`.

Of course, the idea here is that everyone would access the app through the proxy, so the version with the path prefix `/api/v1` is the "correct" one.
