#### Existing language

Let's say you want to translate a page for a language that already has translations for some pages, like Spanish.

In the case of Spanish, the 2-letter code is `es`. So, the directory for Spanish translations is located at `docs/es/`.

!!! tip
    The main ("official") language is English, located at `docs/en/`.

* `allow_methods` - 一个允许跨域请求的 HTTP 方法列表。默认为 `['GET']`。你可以使用 `['*']` 来允许所有标准方法。
* `allow_headers` - 一个允许跨域请求的 HTTP 请求头列表。默认为 `[]`。你可以使用 `['*']` 允许所有的请求头。`Accept`、`Accept-Language`、`Content-Language` 以及 `Content-Type` 请求头总是允许 CORS 请求。
* `allow_credentials` - 指示跨域请求支持 cookies。默认是 `False`。另外，允许凭证时 `allow_origins` 不能设定为 `['*']`，必须指定源。
* `expose_headers` - 指示可以被浏览器访问的响应头。默认为 `[]`。

* `allow_headers` - 교차-출처를 지원하는 HTTP 요청 헤더의 리스트입니다. 기본값은 `[]` 입니다. 모든 헤더들을 허용하기 위해 `['*']` 를 사용할 수 있습니다. `Accept`, `Accept-Language`, `Content-Language` 그리고 `Content-Type` 헤더는 CORS 요청시 언제나 허용됩니다.
* `allow_credentials` - 교차-출처 요청시 쿠키 지원 여부를 설정합니다. 기본값은 `False` 입니다. 또한 해당 항목을 허용할 경우 `allow_origins` 는 `['*']` 로 설정할 수 없으며, 출처를 반드시 특정해야 합니다.

* `allow_methods` - オリジン間リクエストで許可するHTTPメソッドのリスト。デフォルトは `['GET']` です。`['*']`を使用してすべての標準メソッドを許可できます。
* `allow_headers` - オリジン間リクエストでサポートするHTTPリクエストヘッダーのリスト。デフォルトは `[]` です。`['*']`を使用して、すべてのヘッダーを許可できます。CORSリクエストでは、 `Accept` 、 `Accept-Language` 、 `Content-Language` 、 `Content-Type` ヘッダーが常に許可されます。
* `allow_credentials` - オリジン間リクエストでCookieをサポートする必要があることを示します。デフォルトは `False` です。
* `expose_headers` - ブラウザからアクセスできるようにするレスポンスヘッダーを示します。デフォルトは `[]` です。

But at some point, there was no other option than creating something that provided all these features, taking the best ideas from previous tools, and combining them in the best way possible, using language features that weren't even available before (Python 3.6+ type hints).

The same way, there are many compatible tools. Including code generation tools for many languages.

## Pydantic

One particular advantage that is not necessarily obvious is that you can **generate clients** (sometimes called <abbr title="Software Development Kits">**SDKs**</abbr> ) for your API, for many different **programming languages**.

## OpenAPI Client Generators

There are many tools to generate clients from **OpenAPI**.

A common tool is <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>.
