Çeşitli fikirleri en popüler Python editörlerinde test ettim: PyCharm, VS Code, Jedi tabanlı editörler.

Bu test, en son <a href="https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools" class="external-link" target="_blank">Python Developer Survey</a>'ine göre, kullanıcıların yaklaşık %80'inin kullandığı editörleri kapsıyor.

## Benutzerdefinierte Header

Beachten Sie, dass benutzerdefinierte proprietäre Header <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">mittels des Präfix 'X-'</a> hinzugefügt werden können.

## Headers Personalizados

Ten en cuenta que se pueden añadir headers propietarios personalizados <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">usando el prefijo 'X-'</a>.

# WebSockets

You can use <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">WebSockets</a> with **FastAPI**.

## Install `WebSockets`

First you need to install `WebSockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets client

### In production

* [Write good commit messages.](https://cbea.ms/git-commit/#seven-rules)
* [Sign off your commits](https://git-scm.com/docs/git-commit#Documentation/git-commit.txt---signoff) to indicate that you agree to the terms of [Developer Certificate of Origin](https://developercertificate.org/). We can only accept PRs that have all commits signed off.
* Keep commits discrete. Avoid including multiple unrelated changes in a single commit.

    但表单包含文件时，编码为 `multipart/form-data`。使用了 `File`，**FastAPI** 就知道要从请求体的正确位置获取文件。

    编码和表单字段详见 <a href="https://developer.mozilla.org/zh-CN/docs/Web/HTTP/Methods/POST" class="external-link" target="_blank"><abbr title="Mozilla Developer Network">MDN</abbr> Web 文档的 <code>POST </code></a> 小节。

!!! warning "警告"

        // Expire cache snapshots of test Gradle distributions that are older than the tested version
        // Also expire version-specific cache snapshots when they can't be re-used (for 'snapshot-1' developer builds)
        val expireDistributionCache = Spec<GradleVersion> { candidateVersion ->
            (candidateVersion.isSnapshot && candidateVersion < gradleVersion)

!!! tip "豆知識"
    それぞれのステータスコードとどのコードが何のためのコードなのかについて詳細は<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Status" class="external-link" target="_blank"><abbr title="Mozilla Developer Network">MDN</abbr> HTTP レスポンスステータスコードについてのドキュメント</a>を参照してください。

## 名前を覚えるための近道

先ほどの例をもう一度見てみましょう:

```Python hl_lines="6"

!!! warning "Achtung"

!!! note "Technical Details"
    You could also use `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 `status`.
