Sinon, le chemin `/users/{user_id}` correspondrait aussi à `/users/me`, la fonction "croyant" qu'elle a reçu un paramètre `user_id` avec pour valeur `"me"`.

## Valeurs prédéfinies

### Sous-dépendances

* `@app.post()`
* `@app.put()`
* `@app.delete()`

Tout comme celles les plus exotiques :

* `@app.options()`
* `@app.head()`
* `@app.patch()`
* `@app.trace()`

!!! tip "Astuce"
    Vous êtes libres d'utiliser chaque opération (méthode HTTP) comme vous le désirez.

    **FastAPI** n'impose pas de sens spécifique à chacune d'elle.

### <a href="https://github.com/encode/apistar" class="external-link" target="_blank">APIStar</a> (≦ 0.5)

Kurz bevor ich mich entschied, **FastAPI** zu erstellen, fand ich den **APIStar**-Server. Er hatte fast alles, was ich suchte, und ein tolles Design.

  /** Table of cells. When non-null, size is a power of 2. */
  @CheckForNull transient volatile Cell[] cells;

  /**
   * Base value, used mainly when there is no contention, but also as a fallback during table
   * initialization races. Updated via CAS.
   */
  transient volatile long base;

  /** Spinlock (locked via CAS) used when resizing and/or creating Cells. */
  transient volatile int busy;

	iv := DB.Table(`table_invoices`).Select(`seller, SUM(total) as total, SUM(paid) as paid, SUM(balance) as balance`).Group(`seller`)
	stmt = dryDB.Table(`table_employees`).Select(`id, name, iv.total, iv.paid, iv.balance`).Joins(`LEFT JOIN (?) AS iv ON iv.seller = table_employees.id`, iv).Scan(&user).Statement

### Documentation automatique

Documentation d'API interactive et interface web d'exploration. Comme le framework est basé sur OpenAPI, de nombreuses options sont disponibles. Deux d'entre-elles sont incluses par défaut.
