+ "<img src=\"http://example/bar.jpg\">";
        expected = "http://example/foo.jpg";
        assertGetThumbnailUrl(data, expected);

        data = "<img src=\"http://example/foo.jpg\">" //
                + "<img src=\"http://example/bar.jpg\" width=\"100\" height=\"100\">";
        expected = "http://example/bar.jpg";
        assertGetThumbnailUrl(data, expected);

아래와 같은 URL을 사용합니다:

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

여러 `q` *쿼리 매개변수* 값들을 (`foo` 및 `bar`) 파이썬 `list`로 *경로 작동 함수* 내 *함수 매개변수* `q`로 전달 받습니다.

따라서 해당 URL에 대한 응답은 다음과 같습니다:

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

/// tip | 팁

        return Lists.asList("foo", new String[] {"bar", "baz"}).iterator();
      }
    }.test();
  }

  private void checkFooBarBazList(List<String> list) {
    assertThat(list).containsExactly("foo", "bar", "baz").inOrder();
    assertEquals(3, list.size());
    assertIndexIsOutOfBounds(list, -1);
    assertEquals("foo", list.get(0));
    assertEquals("bar", list.get(1));
    assertEquals("baz", list.get(2));

If you communicate with that *path operation* sending two HTTP headers like:

```
X-Token: foo
X-Token: bar
```

The response would be like:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Recap { #recap }

Declare headers with `Header`, using the same common pattern as `Query`, `Path` and `Cookie`.

    Iterator<String> iterator = singletonList("foo").iterator();
    assertEquals("foo", getOnlyElement(iterator, "bar"));
  }

  public void testGetOnlyElement_withDefault_empty() {
    Iterator<String> iterator = emptyIterator();
    assertEquals("bar", getOnlyElement(iterator, "bar"));
  }

  public void testGetOnlyElement_withDefault_empty_null() {
    Iterator<String> iterator = emptyIterator();

  }

  @Override
  protected SortedMap<String, Map<Integer, Character>> makePopulatedMap() {
    RowSortedTable<String, Integer, Character> table = TreeBasedTable.create();
    table.put("foo", 1, 'a');
    table.put("bar", 1, 'b');
    table.put("foo", 3, 'c');
    return unmodifiableRowSortedTable(table).rowMap();
  }

        List<? super String> list) {
      return notSubtype(list);
    }

    // Can't test getSupertype() or getSubtype() because JDK reflection doesn't consider
    // Foo<?> and Foo<? extends Bar> equal for class Foo<T extends Bar>
    @TestSubtype(suppressGetSupertype = true, suppressGetSubtype = true)
    public UseIterable<?> explicitTypeBoundIsSubtypeOfImplicitTypeBound(
        UseIterable<? extends Iterable<?>> obj) {

Das würde bedeuten, dass **FastAPI** einen Body erwartet wie:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Wiederum, nur mit dieser Deklaration erhalten Sie von **FastAPI**:

 *
 * <p>For example, an XML escaper would convert the literal string {@code "Foo<Bar>"} into {@code
 * "Foo&lt;Bar&gt;"} to prevent {@code "<Bar>"} from being confused with an XML tag. When the
 * resulting XML document is parsed, the parser API will return this text as the original literal
 * string {@code "Foo<Bar>"}.
 *
 * <p>A {@code CharEscaper} instance is required to be stateless, and safe when used concurrently by

      .isEqualTo("example.com")
    assertThat(publicSuffixDatabase.getEffectiveTldPlusOne("foo.example.com"))
      .isEqualTo("example.com")
    assertThat(publicSuffixDatabase.getEffectiveTldPlusOne("foo.bar.square.com"))
      .isEqualTo("bar.square.com")
    assertThat(publicSuffixDatabase.getEffectiveTldPlusOne("foo.my.square.com"))
      .isEqualTo("foo.my.square.com")
  }
