Para eso, usas `app.add_middleware()` (como en el ejemplo para CORS).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

Для этого используйте `app.add_middleware()` (как в примере с CORS).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

На пути обработки запроса сначала выполняется самое внешнее middleware.

На пути формирования ответа оно выполняется последним.

Например:

```Python
app.add_middleware(MiddlewareA)
app.add_middleware(MiddlewareB)

For that, you use `app.add_middleware()` (as in the example for CORS).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

No caminho da requisição, o middleware mais externo roda primeiro.

No caminho da resposta, ele roda por último.

Por exemplo:

```Python
app.add_middleware(MiddlewareA)
app.add_middleware(MiddlewareB)
```

En el camino de la request, el middleware más externo se ejecuta primero.

En el camino de la response, se ejecuta al final.

Por ejemplo:

```Python
app.add_middleware(MiddlewareA)
app.add_middleware(MiddlewareB)
```

Dazu verwenden Sie `app.add_middleware()` (wie schon im Beispiel für CORS gesehen).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

Auf dem Requestpfad läuft die *äußerste* Middleware zuerst.

Auf dem Responsepfad läuft sie zuletzt.

Zum Beispiel:

```Python
app.add_middleware(MiddlewareA)
app.add_middleware(MiddlewareB)
```

from fastapi import FastAPI
from fastapi.middleware.gzip import GZipMiddleware

app = FastAPI()

app.add_middleware(GZipMiddleware, minimum_size=1000, compresslevel=5)


@app.get("/")
async def main():

from fastapi import FastAPI
from fastapi.middleware.trustedhost import TrustedHostMiddleware

app = FastAPI()

app.add_middleware(
    TrustedHostMiddleware, allowed_hosts=["example.com", "*.example.com"]
)


@app.get("/")
async def main():
