* `TRACE`

In the HTTP protocol, you can communicate to each path using one (or more) of these "methods".

---

When building APIs, you normally use these specific HTTP methods to perform a specific action.

Normally you use:

* `POST`: to create data.
* `GET`: to read data.
* `PUT`: to update data.
* `DELETE`: to delete data.

So, in OpenAPI, each of the HTTP methods is called an "operation".

Da es sehr einfach ist, ist es relativ intuitiv zu erlernen, obwohl die Dokumentation an einigen Stellen etwas technisch wird.

Es wird auch häufig für andere Anwendungen verwendet, die nicht unbedingt eine Datenbank, Benutzerverwaltung oder eine der vielen in Django enthaltenen Funktionen benötigen. Obwohl viele dieser Funktionen mit Plugins hinzugefügt werden können.

				select {
				case <-done:
					return
				case <-ticker.C:
					res.deleteExpired()
				}
			}
		}(res.done)
	}
	return &res
}

// Purge clears the cache completely.
// onEvict is called for each evicted key.
func (c *LRU[K, V]) Purge() {
	c.mu.Lock()
	defer c.mu.Unlock()
	for k, v := range c.items {
		if c.onEvict != nil {
			c.onEvict(k, v.Value)
		}
		delete(c.items, k)
	}

Sie können auch `from starlette.responses import JSONResponse` verwenden.

**FastAPI** bietet dieselben `starlette.responses` auch via `fastapi.responses` an, als Annehmlichkeit für Sie, den Entwickler. Die meisten verfügbaren Responses kommen aber direkt von Starlette.

Wenn Sie eine `requirements.txt`-Datei verwenden, können Sie die Version wie folgt angeben:

```txt
fastapi==0.45.0
```

Das würde bedeuten, dass Sie genau die Version `0.45.0` verwenden.

Oder Sie können sie auch anpinnen mit:

```txt
fastapi>=0.45.0,<0.46.0
```
