## 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.

JSON só pode conter strings codificadas em UTF-8, portanto não pode conter bytes puros.

接下来我会告诉你如何改进。🤓

## 自定义操作 ID 与更好的方法名 { #custom-operation-ids-and-better-method-names }

你可以**修改**这些操作 ID 的**生成**方式，使之更简单，从而在客户端中得到**更简洁的方法名**。

在这种情况下，你需要用其他方式确保每个操作 ID 依然是**唯一**的。

例如，你可以确保每个*路径操作*都有一个标签，然后基于**标签**和*路径操作***名称**（函数名）来生成操作 ID。

### 自定义唯一 ID 生成函数 { #custom-generate-unique-id-function }

FastAPI 为每个*路径操作*使用一个**唯一 ID**，它既用于**操作 ID**，也用于请求或响应里任何需要的自定义模型名称。

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

Prüfen Sie zunächst, ob Sie [Request Files](../tutorial/request-files.md) zum Hochladen von Binärdaten und [Benutzerdefinierte Response – FileResponse](./custom-response.md#fileresponse--fileresponse-) zum Senden von Binärdaten verwenden können, anstatt sie in JSON zu kodieren.

JSON kann nur UTF-8-kodierte Strings enthalten, es kann daher keine rohen Bytes enthalten.
