## Usando `Depends` e outros { #using-depends-and-others }

Nos endpoints WebSocket você pode importar do `fastapi` e usar:

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

Eles funcionam da mesma forma que para outros endpoints FastAPI/*operações de rota*:

{* ../../docs_src/websockets_/tutorial002_an_py310.py hl[68:69,82] *}

/// info | Informação

`http` 또는 `ws`로 들어오는 모든 요청은 대신 보안 스킴으로 리디렉션됩니다.

{* ../../docs_src/advanced_middleware/tutorial001_py310.py hl[2,6] *}

## `TrustedHostMiddleware` { #trustedhostmiddleware }

HTTP Host Header 공격을 방어하기 위해, 들어오는 모든 요청에 올바르게 설정된 `Host` 헤더가 있어야 하도록 강제합니다.

{* ../../docs_src/advanced_middleware/tutorial002_py310.py hl[2,6:8] *}

다음 인자들을 지원합니다:

Instead of importing documents, configure Fess to crawl your data sources:

**Web Crawling**:
- **Admin Path**: Crawler > Web
- **Supports**: HTTP/HTTPS websites
- **Features**: JavaScript rendering, authentication, custom headers

**File Crawling**:
- **Admin Path**: Crawler > File
- **Supports**: SMB, FTP, local file systems
- **Features**: Access control, file type filtering

**Data Store Crawling**:

        val request = HttpRequest.newBuilder()
            .uri(URI(uri))
            .apply {
                if (githubToken.isPresent) {
                    header("Authorization", "token ${githubToken.get()}")
                }
            }
            .build()
        val response = HttpClient.newHttpClient().send(request, HttpResponse.BodyHandlers.ofString())

          + ")") : "(cache)";
      int responseCode = response.code();

      System.out.printf("%03d: %s %s%n", responseCode, url, responseSource);

      String contentType = response.header("Content-Type");
      if (responseCode != 200 || contentType == null) {
        return;
      }

      MediaType mediaType = MediaType.parse(contentType);

如果您有一组相关的 **cookie**，您可以创建一个 **Pydantic 模型**来声明它们。🍪

这将允许您在**多个地方**能够**重用模型**，并且可以一次性声明所有参数的验证方式和元数据。😎

/// note | 注意

自 FastAPI 版本 `0.115.0` 起支持此功能。🤓

///

/// tip | 提示

此技术同样适用于 `Query` 、 `Cookie` 和 `Header` 。😎

///

## 带有 Pydantic 模型的 Cookie { #cookies-with-a-pydantic-model }

在 **Pydantic** 模型中声明所需的 **cookie** 参数，然后将参数声明为 `Cookie` ：

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}
