## 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.

JSON can only contain UTF-8 encoded strings, so it can't contain raw bytes.

## 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.

## 篩選資料 - 安全性 { #filter-data-security }

為確保你不會回傳超出應有的資料，請參閱[教學 - 回應模型 - 回傳型別](../tutorial/response-model.md)。

## 最佳化回應效能 - 回應模型 - 回傳型別 { #optimize-response-performance-response-model-return-type }

為了在回傳 JSON 資料時最佳化效能，請使用回傳型別或回應模型，如此 Pydantic 會在 Rust 端處理序列化為 JSON，而不經過 Python。更多內容請參閱[教學 - 回應模型 - 回傳型別](../tutorial/response-model.md)。
