*
   * <p>For example, if {@code rangeMap} had the entries {@code [1, 5] => "foo", (6, 8) => "bar",
   * (10, ∞) => "baz"} then {@code rangeMap.subRangeMap(Range.open(3, 12))} would return a range map
   * with the entries {@code (3, 5] => "foo", (6, 8) => "bar", (10, 12) => "baz"}.
   *
   * <p>The returned range map supports all optional operations that this range map supports, except

    assertEquals("", Files.getFileExtension("blah."));
    assertEquals("", Files.getFileExtension(".blah."));
    assertEquals("", Files.getFileExtension("/foo.bar/blah"));
    assertEquals("", Files.getFileExtension("/foo/.bar/blah"));
  }

  public void testGetNameWithoutExtension() {
    assertEquals("", Files.getNameWithoutExtension(".txt"));

    assertThrows(NegativeArraySizeException.class, () -> Atomics.newReferenceArray(-1));
  }

  public void testNewReferenceArray_withStringArray() throws Exception {
    String[] array = {"foo", "bar", "baz"};
    AtomicReferenceArray<String> refArray = Atomics.newReferenceArray(array);
    for (int i = 0; i < array.length; ++i) {
      assertEquals(array[i], refArray.get(i));
    }

Dann, mit einer URL wie:

```
http://localhost:8000/items/?q=foo&q=bar
```

bekommen Sie alle `q`-*Query-Parameter*-Werte (`foo` und `bar`) in einer Python-Liste – `list` – in ihrer *Pfadoperation-Funktion*, im Funktionsparameter `q`, überreicht.

Die Response für diese URL wäre also:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

/// tip | "Tipp"

    assertThat(requestsMade.size).isEqualTo(1)
  }

  @Test
  fun outOfOrderResponses() {
    val firstResponseCode = AtomicInteger()
    val secondResponseCode = AtomicInteger()
    val secondRequest = "/bar"
    val firstRequest = "/foo"
    val latch = CountDownLatch(1)
    val dispatcher: Dispatcher =
      object : Dispatcher() {
        override fun dispatch(request: RecordedRequest): MockResponse {

```

#### 기본값이 있는 필드를 갖는 값의 데이터

하지만 모델의 필드가 기본값이 있어도 ID가 `bar`인 항목(items)처럼 데이터가 값을 갖는다면:

```Python hl_lines="3  5"
{
    "name": "Bar",
    "description": "The bartenders",
    "price": 62,
    "tax": 20.2
}
```

응답에 해당 값들이 포함됩니다.

#### 기본값과 동일한 값을 갖는 데이터

```

本例中，**FastAPI** 不使用 `__init__`，我们要直接在代码中使用。

## 创建实例

使用以下代码创建类实例：

```Python hl_lines="16"
{!../../docs_src/dependencies/tutorial011.py!}
```

这样就可以**参数化**依赖项，它包含 `checker.fixed_content` 的属性 - `"bar"`。

## 把实例作为依赖项

然后，不要再在 `Depends(checker)` 中使用 `Depends(FixedContentQueryChecker)`， 而是要使用 `checker`，因为依赖项是类实例 - `checker`，不是类。

处理依赖项时，**FastAPI** 以如下方式调用 `checker`：

```Python
checker(q="somequery")
```
