ここで、クエリパラメータ `needy` は `str` 型の必須のクエリパラメータです

以下のURLをブラウザで開くと:

```
http://127.0.0.1:8000/items/foo-item
```

...必須のパラメータ `needy` を加えなかったので、以下の様なエラーが表示されます:

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
}

But if you go to the browser at <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, you will see a nice HTTP error of:

```JSON

      "loc": [
        "path",
        "item_id"
      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo"
    }

## Ringkasan, secara bertahap

### Langkah 1: impor `FastAPI`

{* ../../docs_src/first_steps/tutorial001.py hl[1] *}

`FastAPI` adalah class Python yang menyediakan semua fungsionalitas API anda.

/// note | Detail Teknis

`FastAPI` adalah class turunan langsung dari `Starlette`.

Anda bisa menggunakan semua fungsionalitas <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> dengan `FastAPI` juga.

            context = new EncryptionNegotiateContext(mockConfig, null);

            assertNull(context.getCiphers());
            assertEquals(4, context.size()); // Size returns 4 as base (implementation detail)
        }

        @ParameterizedTest
        @DisplayName("Should encode with different cipher counts")
        @ValueSource(ints = { 0, 1, 2, 5, 10 })
        void testEncodeWithDifferentCipherCounts(int count) {

- Enabled concurrent log rotation in kubelet. You can now configure the maximum number of concurrent rotations with the `containerLogMaxWorkers`...
