Artık `Path` ve `Query` kullanmayı gördüğümüze göre, request body bildirimlerinin daha ileri kullanım senaryolarına bakalım.

## `Path`, `Query` ve body parametrelerini karıştırma { #mix-path-query-and-body-parameters }

Öncelikle, elbette `Path`, `Query` ve request body parametre bildirimlerini serbestçe karıştırabilirsiniz ve **FastAPI** ne yapacağını bilir.

        // No results in current page, not done, and fetchMore will throw
        FileEntry initial = entry("one");
        TestIterator it =
                TestIterator.create(tree, parent, "*", null, 0, initial, List.of(new FileEntry[][] { new FileEntry[0] })).throwOnFetch();

        // Act
        assertTrue(it.hasNext());
        assertEquals("one", it.next().getName()); // consume initial

import subprocess

from playwright.sync_api import Playwright, sync_playwright


# Run playwright codegen to generate the code below, copy paste the sections in run()
def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    # Update the viewport manually
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")

如果你想完全禁用 OpenAPI 模式，可以将其设置为 `openapi_url=None`，这样也会禁用使用它的文档用户界面。

## 文档 URLs { #docs-urls }

你可以配置两个文档用户界面，包括：

- **Swagger UI**：服务于 `/docs`。
    - 可以使用参数 `docs_url` 设置它的 URL。
    - 可以通过设置 `docs_url=None` 禁用它。
- **ReDoc**：服务于 `/redoc`。
    - 可以使用参数 `redoc_url` 设置它的 URL。
    - 可以通过设置 `redoc_url=None` 禁用它。

例如，设置 Swagger UI 服务于 `/documentation` 并禁用 ReDoc：

// the token is the last token.
//
// The value is useful to stop processing early or when it is necessary to
// deliver a final empty token (which is different from a nil token).
// One could achieve the same behavior with a custom error value but
// providing one here is tidier.
// See the emptyFinalToken example for a use of this value.
var ErrFinalToken = errors.New("final token")

from typing import Annotated

from fastapi import FastAPI, Query

app = FastAPI()


@app.get("/items/")
async def read_items(q: Annotated[str | None, Query(min_length=3)]):
    results = {"items": [{"item_id": "Foo"}, {"item_id": "Bar"}]}
    if q:
        results.update({"q": q})

                    .map(line => line.value)
                    .join("\n");
                node.textContent = inputCommands;
                const div = document.createElement("div");
                node.style.display = "none";
                node.after(div);
                const termynal = new Termynal(div, {
                    lineData: useLines,
                    noInit: true,
                    lineDelay: 500
                });

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}
```

### Dockerfile { #dockerfile }

Now in the same project directory create a file `Dockerfile` with:

```{ .dockerfile .annotate }
# (1)!

   * list with one before {@code index}. Under these circumstances it returns a pair of elements as
   * a {@link MoveDesc}. The first one is the element that was previously at the end of the heap and
   * is now at some position before {@code index}. The second element is the one that was swapped
