/// warning | Uyarı

Yukarıdaki örnekte olduğu gibi bir `Response`'u doğrudan döndürdüğünüzde, response aynen olduğu gibi döndürülür.

Bir model ile serialize edilmez, vb.

İçinde olmasını istediğiniz veriyi taşıdığından emin olun ve değerlerin geçerli JSON olduğundan emin olun (eğer `JSONResponse` kullanıyorsanız).

///

/// note | Teknik Detaylar

`from starlette.responses import JSONResponse` da kullanabilirsiniz.

System.out.println("REQUEST 1 (new connection)");
try (Response response = client.newCall(request).execute()) {
  // Consume and discard the response body.
  response.body().source().readByteString();
}

System.out.println("REQUEST 2 (pooled connection)");
try (Response response = client.newCall(request).execute()) {
  // Consume and discard the response body.
  response.body().source().readByteString();
}

/// warning

上の例のように `Response` を直接返すと、それはそのまま返されます。

モデルなどによってシリアライズされません。

必要なデータが含まれていること、そして（`JSONResponse` を使用している場合）値が有効な JSON であることを確認してください。

///

/// note | 技術詳細

`from starlette.responses import JSONResponse` を使うこともできます。

**FastAPI** は開発者の利便性のために、`fastapi.responses` と同じ `starlette.responses` を提供しています。しかし、利用可能なレスポンスのほとんどは Starlette から直接提供されています。`status` も同様です。

///

    client = TestClient(app)
    response = client.get("/test1")
    assert response.status_code == 200
    assert response.json() == {"foo": "bar"}

    response = client.get("/test1", params={"var": "baz"})
    assert response.status_code == 200
    assert response.json() == {"foo": "baz"}

    response = client.get("/test2")
    assert response.status_code == 200
    assert response.json() == {"foo": "bar"}

/// note | Technical Details

You could also use `from starlette.requests import Request` and `from starlette.responses import JSONResponse`.

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette. The same with `Request`.

Por exemplo, você pode querer retornar uma *response* em *plain text* ao invés de um JSON para os seguintes erros:
