### `UploadFile`

`UploadFile` 은 다음과 같은 어트리뷰트가 있습니다:

ответе возвращается имеющий смысл HTTP-заголовок `WWW-Authenticate` в соответствии со спецификациями HTTP, <a href="https://datatracker.ietf.org/doc/html/rfc7235#section-3.1" class="external-link" target="_blank">RFC 7235</a>, <a href="https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized" class="external-link" target="_blank">RFC 9110</a>.

Но если по какой-то причине ваши клиенты зависят от старого поведения, вы можете вернуть его, переопределив метод `make_not_authenticated_error`...

Geri kalanı ise **FastAPI** tarafından işlenecektir.

Eğer uygulamanızı çalıştırıp <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a> adresine giderseniz, Flask'tan gelen yanıtı göreceksiniz:

```txt
Hello, World from Flask!
```

Eğer <a href="http://localhost:8000/v2/" class="external-link" target="_blank">http://localhost:8000/v2/</a> adresine giderseniz, FastAPI'dan gelen yanıtı göreceksiniz:

### `UploadFile`

**FastAPI** 提供了以下内容：

### 基于开放标准


* 用于创建 API 的 <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank"><strong>OpenAPI</strong></a> 包含了<abbr title="也被叫做: endpoints, routes">路径</abbr><abbr title="也叫做HTTP方法, 例如 POST, GET, PUT, DELETE">操作</abbr>，请求参数，请求体，安全性等的声明。
* 使用 <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (因为 OpenAPI 本身就是基于 JSON Schema 的)自动生成数据模型文档。

## Installation

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

## 安裝需求

FastAPI 是站在以下巨人的肩膀上：

- <a href="https://www.starlette.dev/" class="external-link" target="_blank">Starlette</a> 負責網頁的部分
- <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> 負責資料的部分

## 安裝

For example, it doesn't receive `datetime` objects, as those are not compatible with JSON.

So, a `datetime` object would have to be converted to a `str` containing the data in <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO format</a>.

The same way, this database wouldn't receive a Pydantic model (an object with attributes), only a `dict`.

You can use `jsonable_encoder` for that.

* Check the currently <a href="https://github.com/fastapi/fastapi/pulls" class="external-link" target="_blank">existing pull requests</a> for your language. You can filter the pull requests by the ones with the label for your language. For example, for Spanish, the label is <a href="https://github.com/fastapi/fastapi/pulls?q=is%3Aopen+sort%3Aupdated-desc+label%3Alang-es+label%3Aawaiting-review" class="external-link" target="_blank">`lang-es`</a>.

これにより<a href="https://github.com/sorcio/async_exit_stack" class="external-link" target="_blank">async-exit-stack</a>と<a href="https://github.com/python-trio/async_generator" class="external-link" target="_blank">async-generator</a>がインストールされます。
