If your app needs to receive and send JSON data, but you need to include binary data in it, you can encode it as base64.

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

Consider first if you can use [Request Files](../tutorial/request-files.md) for uploading binary data and [Custom Response - FileResponse](./custom-response.md#fileresponse--fileresponse-) for sending binary data, instead of encoding it in JSON.

                        System.err.println("\n\nSuite: " + suite);

                        try (BufferedReader reader = eventWriter.reader()) {
                            PrintStream out = System.out;
                            for (String message = reader.readLine(); message != null; message = reader.readLine()) {
                                if (message.startsWith("  1> ")) {
                                    out = System.out;

                }))
                .status(Status.OK)
                .result());
    }

    /**
     * Creates a new boost document rule setting.
     *
     * @param body the request body containing boost document rule information
     * @return JSON response with result status
     */
    // POST /api/admin/boostdoc/setting

Bu örnekte herhangi bir Pydantic model tanımlamadık. Hatta request body JSON olarak <dfn title="bytes gibi düz bir formattan, ör. bytes, Python nesnelerine dönüştürme">ayrıştırılmıyor</dfn>; doğrudan `bytes` olarak okunuyor ve `magic_data_reader()` fonksiyonu bunu bir şekilde parse etmekten sorumlu oluyor.

Buna rağmen, request body için beklenen şemayı tanımlayabiliriz.

- 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。
