## 其他中间件

你可以稍后在 [Advanced User Guide: Advanced Middleware](../advanced/middleware.md){.internal-link target=_blank}阅读更多关于中间件的教程.

In this section we'll see how to use other middlewares.

## Adding ASGI middlewares

As **FastAPI** is based on Starlette and implements the <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> specification, you can use any ASGI middleware.

A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.

It was created to generate the HTML in the backend, not to create APIs used by a modern frontend (like React, Vue.js and Angular) or by other systems (like <abbr title="Internet of Things">IoT</abbr> devices) communicating with it.

* Il existe une extension du protocole TLS (celui qui gère le cryptage au niveau TCP, avant HTTP) appelée <a

## Atalho para lembrar os nomes

Vamos ver o exemplo anterior novamente:

```Python hl_lines="6"

* Há uma extensão para o protocolo TLS (aquele que lida com a criptografia no nível TCP, antes do HTTP) chamado <a href="https://en.wikipedia.org/wiki/Server_Name_Indication" class="external-link" target="_blank"><abbr title="Server Name Indication">SNI</abbr></a>.
    * Esta extensão SNI permite que um único servidor (com um único endereço IP) tenha vários certificados HTTPS e atenda a vários domínios / aplicativos HTTPS.

          pattern: coverage-*
          path: coverage
          merge-multiple: true
      - run: ls -la coverage
      - run: coverage combine coverage
      - run: coverage report
      - run: coverage html --title "Coverage for ${{ github.sha }}"
      - name: Store coverage HTML
        uses: actions/upload-artifact@v4
        with:
          name: coverage-html
          path: htmlcov
          include-hidden-files: true

Ist das nicht der Fall, wird der Inhalt mithilfe der Hilfsfunktion unter `fastapi.openapi.utils.get_openapi` generiert.

Und diese Funktion `get_openapi()` erhält als Parameter:

* `title`: Der OpenAPI-Titel, der in der Dokumentation angezeigt wird.
* `version`: Die Version Ihrer API, z. B. `2.5.0`.
* `openapi_version`: Die Version der verwendeten OpenAPI-Spezifikation. Standardmäßig die neueste Version: `3.1.0`.

Nó sẽ cho thấy một JSON bắt đầu giống như:

```JSON
{
    "openapi": "3.1.0",
    "info": {
        "title": "FastAPI",
        "version": "0.1.0"
    },
    "paths": {
        "/items/": {
            "get": {
                "responses": {
                    "200": {
