### Target language

Translate to Simplified Chinese (简体中文).

Language code: zh.

### Grammar and tone

1) Use clear, concise technical Chinese consistent with existing docs.
2) Address the reader naturally (commonly using “你/你的”).

### Headings

1) Follow existing Simplified Chinese heading style (short and descriptive).
2) Do not add trailing punctuation to headings.

# CORS（跨域资源共享）

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS 或者「跨域资源共享」</a> 指浏览器中运行的前端拥有与后端通信的 JavaScript 代码，而后端处于与前端不同的「源」的情况。

## 源

源是协议（`http`，`https`）、域（`myapp.com`，`localhost`，`localhost.tiangolo.com`）以及端口（`80`、`443`、`8080`）的组合。

因此，这些都是不同的源：

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

即使它们都在 `localhost` 中，但是它们使用不同的协议或者端口，所以它们都是不同的「源」。

## 步骤

По умолчанию **FastAPI** автоматически преобразует возвращаемое значение в JSON с помощью `jsonable_encoder`, как описано в [JSON кодировщик](../tutorial/encoder.md){.internal-link target=_blank}.

Затем "под капотом" эти данные, совместимые с JSON (например `dict`), помещаются в `JSONResponse`, который используется для отправки ответа клиенту.

Но вы можете возвращать `JSONResponse` напрямую из ваших *операций пути*.

查看文档 <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs。</a>

下图显示的是主应用 API 文档，只包括其自有的*路径操作*。

<img src="/img/tutorial/sub-applications/image01.png">

然后查看子应用文档 <a href="http://127.0.0.1:8000/subapi/docs" class="external-link" target="_blank">http://127.0.0.1:8000/subapi/docs。</a>

下图显示的是子应用的 API 文档，也是只包括其自有的*路径操作*，所有这些路径操作都在 `/subapi` 子路径前缀下。

Example:

    Source (English):

        «««
        <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel docs</a>
        »»»

    Result (German):

        «««
        <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel-Dokumentation</a>
        »»»

        groovyOptions.encoding = "utf-8"
        configureCompileTask(options)
    }
}

Starlette (и **FastAPI**) основаны на <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, что делает их совместимыми и со стандартной библиотекой Python <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a>, и с <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.

It also includes what has changed, how validations are now more correct and strict, possible caveats, etc.

You can read it to understand better what has changed.

## Tests { #tests }

Make sure you have [tests](../tutorial/testing.md){.internal-link target=_blank} for your app and you run them on continuous integration (CI).
