Sie können für Typdeklarationen auch `str`, `float`, `bool` und viele andere komplexe Datentypen verwenden.

Mehrere davon werden wir in den nächsten Kapiteln erkunden.

Wenn Sie *Pfadoperationen* erstellen, haben Sie manchmal einen fixen Pfad.

Etwa `/users/me`, um Daten über den aktuellen Benutzer zu erhalten.

When we create an instance of the `OAuth2PasswordBearer` class we pass in the `tokenUrl` parameter. This parameter contains the URL that the client (the frontend running in the user's browser) will use to send the `username` and `password` in order to get a token.

### Définir l’ordre des tags { #order-of-tags }

L’ordre de chaque dictionnaire de métadonnées de tag définit également l’ordre affiché dans l’interface utilisateur de la documentation.

Par exemple, même si `users` viendrait après `items` par ordre alphabétique, il est affiché avant, car nous avons ajouté ses métadonnées comme premier dictionnaire de la liste.

   * higher value than you need can waste space and time, and a significantly lower value can lead
   * to thread contention. But overestimates and underestimates within an order of magnitude do not
   * usually have much noticeable impact. A value of one permits only one thread to modify the cache
   * at a time, but since read operations and cache loading computations can proceed concurrently,

### 檢視文件 { #check-the-docs }

現在檢視文件時，會看到所有額外的中繼資料：

### 標籤順序 { #order-of-tags }

每個標籤中繼資料 dictionary 在清單中的順序，也會決定它們在文件介面中的顯示順序。

例如，雖然按字母排序時 `users` 會排在 `items` 之後，但因為我們在清單中將它的中繼資料放在第一個，所以它會先顯示。

## OpenAPI URL { #openapi-url }
