 * This test binds two different web servers (IPv4 and IPv6) to the same port, but on different

 * `::1` will reach the IPv6 server.

* This also allows using automatic **client code generation** in many languages.

Interactive API documentation and exploration web user interfaces. As the framework is based on OpenAPI, there are multiple options, 2 included by default.

 * [OkHttp's TLS Configuration History][tls_history] to track these changes.

Actually, all (or most) of the web frameworks work in this same way.

You never call those functions directly. They are called by your framework (in this case, **FastAPI**).

* 使用 [**JSON Schema**](https://json-schema.org/) 自动生成数据模型文档（因为 OpenAPI 本身就是基于 JSON Schema 的）。
* 经过了缜密的研究后围绕这些标准而设计。并非狗尾续貂。
* 这也允许了在很多语言中自动**生成客户端代码**。

### 自动生成文档 { #automatic-docs }

交互式 API 文档以及具探索性 web 界面。因为该框架是基于 OpenAPI，所以有很多可选项，FastAPI 默认自带两个交互式 API 文档。

* [**Swagger UI**](https://github.com/swagger-api/swagger-ui)，可交互式操作，能在浏览器中直接调用和测试你的 API。
