* 如果你要比較 Starlette，請將其與 Sanic、Flask、Django 等網頁框架（或微框架）進行比較。
* **FastAPI**：
    * 就像 Starlette 使用 Uvicorn 並不能比它更快一樣， **FastAPI** 使用 Starlette，所以它不能比它更快。
    * FastAPI 在 Starlette 基礎之上提供了更多功能。包含建構 API 時所需要的功能，例如資料驗證和序列化。FastAPI 可以幫助你自動產生 API 文件，（應用程式啟動時將會自動生成文件，所以不會增加應用程式運行時的開銷）。
    * 如果你沒有使用 FastAPI 而是直接使用 Starlette（或其他工具，如 Sanic、Flask、Responder 等），你將必須自行實現所有資料驗證和序列化。因此，你的最終應用程式仍然具有與使用 FastAPI 建置相同的開銷。在許多情況下，這種資料驗證和序列化是應用程式中編寫最大量的程式碼。

# Security Policy

Security is very important for FastAPI and its community. 🔒

Learn more about it below. 👇

## Versions

The latest version of FastAPI is supported.

You are encouraged to [write tests](https://fastapi.tiangolo.com/tutorial/testing/) for your application and update your FastAPI version frequently after ensuring that your tests are passing. This way you will benefit from the latest features, bug fixes, and **security fixes**.

Was hat **FastAPI** inspiriert, ein Vergleich zu Alternativen, und was FastAPI von diesen gelernt hat.

## Einführung

**FastAPI** würde ohne die frühere Arbeit anderer nicht existieren.

Es wurden zuvor viele Tools entwickelt, die als Inspiration für seine Entwicklung dienten.

/// note

You can use the `StaticFiles` class to serve static files, like JavaScript, CSS, images, etc.

Read more about it in the [FastAPI docs for Static Files](https://fastapi.tiangolo.com/tutorial/static-files/).

You can import it directly from `fastapi.staticfiles`:

```python
from fastapi.staticfiles import StaticFiles
```

from fastapi import FastAPI, Request
from fastapi.responses import HTMLResponse
from fastapi.staticfiles import StaticFiles
from fastapi.templating import Jinja2Templates

app = FastAPI()

app.mount("/static", StaticFiles(directory="static"), name="static")


templates = Jinja2Templates(directory="templates")


@app.get("/items/{id}", response_class=HTMLResponse)
async def read_item(request: Request, id: str):

import pytest
from fastapi import FastAPI
from fastapi.testclient import TestClient


@pytest.fixture(name="app", scope="module")
def get_app():
    with pytest.warns(DeprecationWarning):
        from docs_src.events.tutorial002 import app
    yield app


def test_events(app: FastAPI):
    with TestClient(app) as client:
        response = client.get("/items/")
        assert response.status_code == 200, response.text

## GraphQL Libraries

Here are some of the **GraphQL** libraries that have **ASGI** support. You could use them with **FastAPI**:

FastAPI unterstützt (und empfiehlt die Verwendung von) `Annotated` seit Version 0.95.0.

Wenn Sie eine ältere Version haben, werden Sie Fehler angezeigt bekommen, wenn Sie versuchen, `Annotated` zu verwenden.
