そして、これらの通信はすべて同じWebSocket接続を使用します。

## `Depends` などの使用 { #using-depends-and-others }

WebSocketエンドポイントでは、`fastapi` から以下をインポートして使用できます。

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

これらは、他のFastAPI エンドポイント/*path operations* の場合と同じように機能します。

Read the new docs: [Query Parameter Models](https://fastapi.tiangolo.com/tutorial/query-param-models/).

#### `Header` Parameter Models

Use Pydantic models for `Header` parameters:

```python
from typing import Annotated

from fastapi import FastAPI, Header
from pydantic import BaseModel

app = FastAPI()


class CommonHeaders(BaseModel):
    host: str

    // Test wrapper functionality inheritance
    @Test
    public void test_inheritedMethods_areProperlyDelegated() {
        final String customPath = "/api/v1/test";
        final String testHeader = "X-Test-Header";
        final String testHeaderValue = "TestValue";

        mockRequest.addHeader(testHeader, testHeaderValue);
        mockRequest.setMethod("POST");
        mockRequest.setRequestURI("/test/uri");
