## Compartilhando dependências `Annotated` { #share-annotated-dependencies }

Nos exemplos acima, você pode ver que existe uma pequena **duplicação de código**.

## `username`과 데이터 형태 검증하기 { #verify-the-username-and-data-shape }

`username`을 얻었는지 확인하고, 스코프를 추출합니다.

그런 다음 Pydantic 모델로 데이터를 검증합니다(`ValidationError` 예외를 잡습니다). JWT 토큰을 읽거나 Pydantic으로 데이터를 검증하는 과정에서 오류가 나면, 앞에서 만든 `HTTPException`을 raise합니다.

如此一來，你只需撰寫一次共用程式碼，**FastAPI** 會替你的各個「路徑操作」呼叫它。

/// check | 檢查

注意，你不必建立特殊的類別並把它傳到 **FastAPI** 去「註冊」或做類似的事。

只要把它傳給 `Depends`，**FastAPI** 就知道該怎麼處理其餘的部分。

## 共用 `Annotated` 依賴 { #share-annotated-dependencies }

在上面的範例中，可以看到有一點點的「重複程式碼」。

當你要使用 `common_parameters()` 這個依賴時，你得寫出完整的型別註解搭配 `Depends()`：

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

# Advanced: Use Remote Build Execution (RBE) (internal developers only)
#
#   RBE dramatically speeds up builds and testing. It also gives you a
#   public URL to share your build results with collaborators. However,
#   it is only available to a limited set of internal TensorFlow developers.
#
#   RBE is incompatible with local caching, so you must remove
