## 依赖项树与作用域

再次查看这个依赖项树与作用域。

`get_current_active_user` 依赖项包含子依赖项 `get_current_user`，并在 `get_current_active_user`中声明了作用域 `"me"` 包含所需作用域列表 ，在 `security_scopes.scopes` 中传递给 `get_current_user`。

*路径操作*自身也声明了作用域，`"items"`，这也是 `security_scopes.scopes` 列表传递给 `get_current_user` 的。

依赖项与作用域的层级架构如下：

* *路径操作* `read_own_items` 包含：
    * 依赖项所需的作用域 `["items"]`：
    * `get_current_active_user`:

  @Test
  fun crudVerbs() {
    val contentType = "application/json".toMediaType()
    val body = "{}".toRequestBody(contentType)

    val get = Request.Builder().url("http://localhost/api").get().build()
    assertThat(get.method).isEqualTo("GET")
    assertThat(get.body).isNull()

    val head = Request.Builder().url("http://localhost/api").head().build()
    assertThat(head.method).isEqualTo("HEAD")

    }
  }
}

private fun Request.requestForCache(): Request {
  val cacheUrlOverride = cacheUrlOverride

  return if (cacheUrlOverride != null && (method == "GET" || method == "POST")) {
    newBuilder()
      .get()
      .url(cacheUrlOverride)
      .cacheUrlOverride(null)
      .build()
  } else {
    this
  }

* Validate that there is an `item_id` in the path for `GET` and `PUT` requests.
* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
    * If it is not, the client will see a useful, clear error.
* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests.
    * As the `q` parameter is declared with `= None`, it is optional.

    val encodedFragment: String? = httpUrl.encodedFragment()
    val fragment: String? = httpUrl.fragment()
    val getFromUrl: HttpUrl? = HttpUrl.get(URL(""))
    val getFromUri: HttpUrl? = HttpUrl.get(URI(""))
    val parse: HttpUrl? = HttpUrl.parse("")
  }

  @Test @Disabled
  fun handshakeCertificates() {
    val handshakeCertificates = HandshakeCertificates.Builder().build()

우리 역시 이제부터 메소드를 "**작동**"이라고 부를 것입니다.

#### *경로 작동 데코레이터* 정의

```Python hl_lines="6"
{!../../../docs_src/first_steps/tutorial001.py!}
```

`@app.get("/")`은 **FastAPI**에게 바로 아래에 있는 함수가 다음으로 이동하는 요청을 처리한다는 것을 알려줍니다.

* 경로 `/`
* <abbr title="HTTP GET 메소드"><code>get</code> 작동</abbr> 사용

!!! info "`@decorator` 정보"
    이 `@something` 문법은 파이썬에서 "데코레이터"라 부릅니다.

## Abhängigkeitsbaum und Scopes

Sehen wir uns diesen Abhängigkeitsbaum und die Scopes noch einmal an.

Da die Abhängigkeit `get_current_active_user` von `get_current_user` abhängt, wird der bei `get_current_active_user` deklarierte Scope `"me"` in die Liste der erforderlichen Scopes in `security_scopes.scopes` aufgenommen, das an `get_current_user` übergeben wird.
