Em sua rota WebSocket você pode esperar (`await`) por mensagens e enviar mensagens.

Você pode receber e enviar dados binários, de texto e JSON.

클라이언트가 추가 데이터를 보내려고 하면 **오류** 응답을 받게 됩니다.

예를 들어, 클라이언트가 폼 필드를 보내려고 하면:

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

`extra` 필드가 허용되지 않는다는 오류 응답을 받게 됩니다:

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

如果客戶端嘗試在**查詢參數**中發送一些**額外的**資料，他們將會收到一個**錯誤**回應。

例如，如果客戶端嘗試發送一個值為 `plumbus` 的 `tool` 查詢參數，如：

```http
https://example.com/items/?limit=10&tool=plumbus
```

他們將收到一個**錯誤**回應，告訴他們查詢參數 `tool` 是不允許的：

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus"
        }
    ]
}

```

you would receive the multiple `q` *query parameters'* values (`foo` and `bar`) in a Python `list` inside your *path operation function*, in the *function parameter* `q`.

So, the response to that URL would be:

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

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["cookie", "santa_tracker"],
            "msg": "Extra inputs are not permitted",
            "input": "good-list-please",
