You can probably skip this part.

There's an alternative way to define this logic to be executed during *startup* and during *shutdown*.

from fastapi import FastAPI

app = FastAPI()

items = {}


@app.on_event("startup")
async def startup_event():
    items["foo"] = {"name": "Fighters"}
    items["bar"] = {"name": "Tenders"}


@app.get("/items/{item_id}")
async def read_items(item_id: str):

```

Die folgenden Argumente werden unterstützt:

* `minimum_size` – Antworten, die kleiner als diese Mindestgröße in Bytes sind, nicht per GZip komprimieren. Der Defaultwert ist `500`.

## Andere Middlewares

Es gibt viele andere ASGI-Middlewares.

Zum Beispiel:

from fastapi.testclient import TestClient

app = FastAPI()

items = {}


@app.on_event("startup")
async def startup_event():
    items["foo"] = {"name": "Fighters"}
    items["bar"] = {"name": "Tenders"}


@app.get("/items/{item_id}")
async def read_items(item_id: str):
    return items[item_id]


def test_read_items():
    with TestClient(app) as client:
        response = client.get("/items/foo")

	// connChange will be signaled whenever State has been updated, or at regular intervals.
	// Holding the lock allows safe reads of State, and guarantees that changes will be detected.
	connChange *sync.Cond
	handlers   *handlers

	remote             *RemoteClient
	clientPingInterval time.Duration
	connPingInterval   time.Duration
	blockConnect       chan struct{}

	incomingBytes func(n int64) // Record incoming bytes.

## Meinungen

```Python hl_lines="2-4"
{!../../docs_src/dependencies/tutorial007.py!}
```

Der ge`yield`ete Wert ist das, was in *Pfadoperationen* und andere Abhängigkeiten eingefügt wird:

```Python hl_lines="4"
{!../../docs_src/dependencies/tutorial007.py!}
```

Der auf die `yield`-Anweisung folgende Code wird ausgeführt, nachdem die Response gesendet wurde:

from typing import Union

from fastapi import Body, FastAPI, status
from fastapi.responses import JSONResponse

app = FastAPI()

items = {"foo": {"name": "Fighters", "size": 6}, "bar": {"name": "Tenders", "size": 3}}


@app.put("/items/{item_id}")
async def upsert_item(
    item_id: str,
    name: Union[str, None] = Body(default=None),
    size: Union[int, None] = Body(default=None),
):
    if item_id in items:
