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`.

        * Nas respostas, o `set` será convertido para uma `list`.
        * O esquema gerado vai especificar que os valores do `set` são unicos (usando o `uniqueItems` do JSON Schema).
* `bytes`:
    * O `bytes` padrão do Python.
    * Em requisições e respostas será representado como uma `str`.
    * O esquema gerado vai especificar que é uma `str` com o "formato" `binary`.
* `Decimal`:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

erhält er eine Error-Response, die ihm mitteilt, dass das Feld `extra` nicht erlaubt ist:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }

When you return a `Response` directly, like in the example above, it will be returned directly.

It won't be serialized with a model, etc.

Make sure it has the data you want it to have, and that the values are valid JSON (if you are using `JSONResponse`).

/// note | Technical Details

You could also use `from starlette.responses import JSONResponse`.

For internal purposes, we use binary formats for their brevity.
We use the `Serializer` abstraction to separate the actual implementation of serialization from its uses.

When sharing data with external tools, we use JSON.

## Status

ACCEPTED

## Consequences

* The configuration cache serialization infrastructure should be used for all serialization.

          System.out.println(response.body().string());
        }
      }
    ```

### Parse a JSON Response With Moshi ([.kt][ParseResponseWithMoshiKotlin], [.java][ParseResponseWithMoshiJava])

[Moshi](https://github.com/square/moshi) is a handy API for converting between JSON and Java objects. Here we're using it to decode a JSON response from a GitHub API.

    public String searchLog;

    /** The user info setting. */
    public String userInfo;

    /** The user favorite setting. */
    public String userFavorite;

    /** The web API JSON setting. */
    public String webApiJson;

    /** The default label value setting. */
    public String defaultLabelValue;

    /** The append query parameter setting. */
    public String appendQueryParameter;

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

They will receive an error response telling them that the field `extra` is not allowed:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }

Sie wird nicht mit einem Modell usw. serialisiert.

Stellen Sie sicher, dass sie die gewünschten Daten enthält und dass die Werte gültiges JSON sind (wenn Sie `JSONResponse` verwenden).

Sie können auch `from starlette.responses import JSONResponse` verwenden.
