## Einfache Verwendung

Näher betrachtet, werden *Pfadoperation-Funktionen* deklariert, um verwendet zu werden, wann immer ein *Pfad* und eine *Operation* übereinstimmen, und dann kümmert sich **FastAPI** darum, die Funktion mit den richtigen Parametern aufzurufen, die Daten aus der Anfrage extrahierend.

   * which is still better than alternatives.
   *
   * Per-thread hash codes are initialized to random values.
   * Contention and/or table collisions are indicated by failed
   * CASes when performing an update operation (see method
   * retryUpdate). Upon a collision, if the table size is less than
   * the capacity, it is doubled in size unless some other thread
   * holds the lock. If a hashed slot is empty, and lock is

// TestDeleteBucket - validates DELETE bucket operation.
func (s *TestSuiteCommon) TestDeleteBucket(c *check) {

	// HTTP request to create the bucket.

我们还可以添加一个 `tags` 列表和额外的 `responses` 列表，这些参数将应用于此路由器中包含的所有*路径操作*。

我们可以添加一个 `dependencies` 列表，这些依赖项将被添加到路由器中的所有*路径操作*中，并将针对向它们发起的每个请求执行/解决。

请注意，和[*路径操作装饰器*中的依赖项](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}很类似，没有值会被传递给你的*路径操作函数*。

最终结果是项目相关的路径现在为：

* `/items/`
* `/items/{item_id}`

...如我们所愿。

* 它们将被标记为仅包含单个字符串 `"items"` 的标签列表。
