例えば、URL内に複数回出現するクエリパラメータ`q`を宣言するには以下のように書きます:

{* ../../docs_src/query_params_str_validations/tutorial011.py hl[9] *}

そしてURLは以下です:

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

複数の*クエリパラメータ*の値`q`（`foo`と`bar`）を*path operation関数*内で*関数パラメータ*`q`としてPythonの`list`を受け取ることになります。

そのため、このURLのレスポンスは以下のようになります:

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

        FileSizeFormat format = new FileSizeFormat();

        assertEquals("0/800 B", format.formatProgress(0L, 800L));
        assertEquals("400/800 B", format.formatProgress(400L, 800L));
        assertEquals("800 B", format.formatProgress(800L, 800L));

        assertEquals("0/8.0 kB", format.formatProgress(0L, 8000L));
        assertEquals("0.4/8.0 kB", format.formatProgress(400L, 8000L));

### Hey API { #hey-api }

Once we have a FastAPI app with the models, we can use Hey API to generate a TypeScript client. The fastest way to do that is via npx.

```sh
npx @hey-api/openapi-ts -i http://localhost:8000/openapi.json -o src/client
```

This will generate a TypeScript SDK in `./src/client`.

{* ../../docs_src/query_params_str_validations/tutorial011_an_py310.py hl[9] *}

Entonces, con una URL como:

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

recibirías los múltiples valores del *query parameter* `q` (`foo` y `bar`) en una `list` de Python dentro de tu *path operation function*, en el *parámetro de función* `q`.

Sobald wir eine FastAPI-App mit den Modellen haben, können wir Hey API verwenden, um einen TypeScript-Client zu generieren. Der schnellste Weg das zu tun, ist über npx.

```sh
npx @hey-api/openapi-ts -i http://localhost:8000/openapi.json -o src/client
```

Dies generiert ein TypeScript-SDK in `./src/client`.

### Hey API { #hey-api }

Depois que tivermos uma aplicação FastAPI com os modelos, podemos usar o Hey API para gerar um cliente TypeScript. A forma mais rápida é via npx.

```sh
npx @hey-api/openapi-ts -i http://localhost:8000/openapi.json -o src/client
```

Isso gerará um SDK TypeScript em `./src/client`.
