在其中一个响应发送之后，就不能再发送其他响应了。

///

/// tip | 提示

如果你在 *路径操作函数* 的代码中引发任何异常，它都会被传递给带有 `yield` 的依赖项，包括 `HTTPException`。在大多数情况下，你会希望在带有 `yield` 的依赖中重新抛出相同的异常或一个新的异常，以确保它被正确处理。

///

## 提前退出与 `scope` { #early-exit-and-scope }

通常，带有 `yield` 的依赖的退出代码会在响应发送给客户端**之后**执行。

但如果你知道在从 *路径操作函数* 返回之后不再需要使用该依赖，你可以使用 `Depends(scope="function")` 告诉 FastAPI：应当在 *路径操作函数* 返回后、但在**响应发送之前**关闭该依赖。

一旦送出了其中一個回應，就不能再送出其他回應。

///

/// tip

如果你在路徑操作函式的程式碼中拋出任何例外，它會被傳遞到使用 `yield` 的相依中（包含 `HTTPException`）。大多數情況你會想在該使用 `yield` 的相依中重新拋出相同的例外或一個新的例外，以確保它被正確處理。

///

## 提早關閉與 `scope` { #early-exit-and-scope }

通常，含 `yield` 的相依之結束程式碼會在回應送出給用戶端之後才執行。

但如果你確定在從路徑操作函式返回後就不會再使用該相依，你可以使用 `Depends(scope="function")`，告訴 FastAPI 應在路徑操作函式返回之後、但在回應送出之前關閉該相依。
