# Return a Response Directly { #return-a-response-directly }

When you create a **FastAPI** *path operation* you can normally return any data from it: a `dict`, a `list`, a Pydantic model, a database model, etc.

If you declare a [Response Model](../tutorial/response-model.md) FastAPI will use it to serialize the data to JSON, using Pydantic.

# 直接回傳 Response { #return-a-response-directly }

當你建立一個 **FastAPI** 的路徑操作 (path operation) 時，通常可以從中回傳任何資料：`dict`、`list`、Pydantic 模型、資料庫模型等。

如果你宣告了 [回應模型](../tutorial/response-model.md)，FastAPI 會用 Pydantic 將資料序列化為 JSON。

如果你沒有宣告回應模型，FastAPI 會使用在[JSON 相容編碼器](../tutorial/encoder.md)中說明的 `jsonable_encoder`，並把它放進 `JSONResponse`。

但你也可以直接從路徑操作回傳 `JSONResponse`。

# Request'i Doğrudan Kullanmak { #using-the-request-directly }

Şu ana kadar, ihtiyacınız olan request parçalarını tipleriyle birlikte tanımlıyordunuz.

Verileri şuradan alarak:

* path'ten parameter olarak.
* Header'lardan.
* Cookie'lerden.
* vb.

Bunu yaptığınızda **FastAPI**, bu verileri doğrular (validate eder), dönüştürür ve API'niz için dokümantasyonu otomatik olarak üretir.
