- 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。

{* ../../docs_src/templates/tutorial001_py310.py hl[4,11,15:18] *}

/// note

在 FastAPI 0.108.0、Starlette 0.29.0 之前，`name` 是第一個參數。

此外，在更早的版本中，`request` 物件是作為 context 的鍵值對之一傳給 Jinja2 的。

## Base64 vs Arquivos { #base64-vs-files }

Primeiro, considere se você pode usar [Arquivos na request](../tutorial/request-files.md) para fazer upload de dados binários e [Response personalizada - FileResponse](./custom-response.md#fileresponse--fileresponse-) para enviar dados binários, em vez de codificá-los em JSON.

Ahora que hemos visto cómo usar `Path` y `Query`, veamos usos más avanzados de las declaraciones del request body.

## Mezclar `Path`, `Query` y parámetros del cuerpo { #mix-path-query-and-body-parameters }

Primero, por supuesto, puedes mezclar las declaraciones de parámetros de `Path`, `Query` y del request body libremente y **FastAPI** sabrá qué hacer.

* the payload: die Payload
* the performance: NOT die Performance
* the query: die Query
* the recap: die Zusammenfassung
* the request (what the client sends to the server): der Request
* the request body: der Requestbody
* the request bodies (plural): die Requestbodys
* the response (what the server sends back to the client): die Response
* the return type: der Rückgabetyp
