Then if you go to the URLs at `/openapi.json`, `/docs`, or `/redoc` you will just get a `404 Not Found` error like:

```JSON

    "detail": "Not Found"
}

# 응답을 직접 반환하기

**FastAPI**에서 *경로 작업(path operation)*을 생성할 때, 일반적으로 `dict`, `list`, Pydantic 모델, 데이터베이스 모델 등의 데이터를 반환할 수 있습니다.

기본적으로 **FastAPI**는 [JSON 호환 가능 인코더](../tutorial/encoder.md){.internal-link target=_blank}에 설명된 `jsonable_encoder`를 사용해 해당 반환 값을 자동으로 `JSON`으로 변환합니다.

그런 다음, JSON 호환 데이터(예: `dict`)를 `JSONResponse`에 넣어 사용자의 응답을 전송하는 방식으로 처리됩니다.

그러나 *경로 작업*에서 `JSONResponse`를 직접 반환할 수도 있습니다.

예를 들어, 사용자 정의 헤더나 쿠키를 반환해야 하는 경우에 유용할 수 있습니다.

# 直接返回响应

当你创建一个 **FastAPI** *路径操作* 时，你可以正常返回以下任意一种数据：`dict`，`list`，Pydantic 模型，数据库模型等等。

**FastAPI** 默认会使用 `jsonable_encoder` 将这些类型的返回值转换成 JSON 格式，`jsonable_encoder` 在 [JSON 兼容编码器](../tutorial/encoder.md){.internal-link target=_blank} 中有阐述。

然后，**FastAPI** 会在后台将这些兼容 JSON 的数据（比如字典）放到一个 `JSONResponse` 中，该 `JSONResponse` 会用来发送响应给客户端。

但是你可以在你的 *路径操作* 中直接返回一个 `JSONResponse`。

直接返回响应可能会有用处，比如返回自定义的响应头和 cookies。

This program posts data to a service. [Full source][post_example].

public static final MediaType JSON = MediaType.get("application/json");

OkHttpClient client = new OkHttpClient();

String post(String url, String json) throws IOException {
  RequestBody body = RequestBody.create(json, JSON);
  Request request = new Request.Builder()

- `/items/{item_id}` এর জন্য `PUT` অনুরোধের বডি JSON হিসাবে পড়ুন:
  - লক্ষ করুন, `name` একটি প্রয়োজনীয় অ্যাট্রিবিউট হিসাবে বিবেচনা করেছে এবং এটি `str` হতে হবে।
  - লক্ষ করুন এখানে, `price` অ্যাট্রিবিউটটি আবশ্যক এবং এটি `float` হতে হবে।
  - লক্ষ করুন `is_offer` একটি ঐচ্ছিক অ্যাট্রিবিউট এবং এটি `bool` হতে হবে যদি উপস্থিত থাকে।
  - এই সবটি গভীরভাবে অবস্থানরত JSON অবজেক্টগুলিতেও কাজ করবে।
- স্বয়ংক্রিয়ভাবে JSON হতে এবং JSON থেকে কনভার্ট করুন।
