http://127.0.0.1:8000/items/foo?short=on
```

或

```
http://127.0.0.1:8000/items/foo?short=yes
```

或任何其他大小寫變化（全大寫、首字母大寫等），你的函式會將參數 `short` 視為 `bool` 值 `True`。否則為 `False`。

## 多個路徑與查詢參數 { #multiple-path-and-query-parameters }

你可以同時宣告多個路徑參數與查詢參數，FastAPI 會自動分辨。

而且不必按特定順序宣告。

會依名稱辨識：

{* ../../docs_src/query_params/tutorial004_py310.py hl[6,8] *}

## 必填查詢參數 { #required-query-parameters }

     * @throws IOException if an I/O error occurs
     */
    boolean ensureConnected() throws IOException;

    /**
     * Gets DFS referrals for the specified path.
     *
     * @param ctx the CIFS context
     * @param name the DFS path to resolve
     * @param targetHost the target host name
     * @param targetDomain the target domain
     * @param rn the referral number
     * @return dfs referral

```console
$ pip install jinja2

---> 100%
```

## 使用 `Jinja2Templates` { #using-jinja2templates }

- 匯入 `Jinja2Templates`。
- 建立一個可重複使用的 `templates` 物件。
- 在會回傳模板的「*路徑操作（path operation）*」中宣告一個 `Request` 參數。
- 使用你建立的 `templates` 來渲染並回傳 `TemplateResponse`，傳入模板名稱、`request` 物件，以及在 Jinja2 模板中使用的「context」鍵值對字典。

# Return a Response Directly { #return-a-response-directly }

When you create a **FastAPI** *path operation* you can normally return any data from it: a `dict`, a `list`, a Pydantic model, a database model, etc.

If you declare a [Response Model](../tutorial/response-model.md) FastAPI will use it to serialize the data to JSON, using Pydantic.

다음 명령어들에서 사용할 수 있는 몇몇 [환경 변수](environment-variables.md)를 생성하거나 수정하는 것을 의미합니다.

그 변수 중 하나가 `PATH` 변수입니다.

/// tip

`PATH` 환경 변수에 대해 더 알아보려면 [환경 변수](environment-variables.md#path-environment-variable) 섹션을 참고하세요.

///

가상 환경을 활성화하면 가상 환경의 경로인 `.venv/bin`(Linux와 macOS) 또는 `.venv\Scripts`(Windows)를 `PATH` 환경 변수에 추가합니다.

가령 환경을 활성화하기 전에는 `PATH` 변수가 다음과 같았다고 해보겠습니다:

//// tab | Linux, macOS

```plaintext

///

/// tip | İpucu

FastAPI'nin [VS Code için resmi bir eklentisi](https://marketplace.visualstudio.com/items?itemName=FastAPILabs.fastapi-vscode) (ve Cursor) vardır; path operation gezgini, path operation araması, testlerde CodeLens ile gezinme (testlerden tanıma atlama) ve FastAPI Cloud deploy ve logları gibi pek çok özelliği doğrudan editörünüzden sunar.

class EventSourceResponse(StreamingResponse):
    """Streaming response with `text/event-stream` media type.

    Use as `response_class=EventSourceResponse` on a *path operation* that uses `yield`
    to enable Server Sent Events (SSE) responses.

    Works with **any HTTP method** (`GET`, `POST`, etc.), which makes it compatible
    with protocols like MCP that stream SSE over `POST`.

        String urlWithTabs = "http://example.com/path\twith\ttabs";
        StatsKeyObject key = new StatsKeyObject("test");
        key.setUrl(urlWithTabs);
