También vas a necesitar un servidor ASGI para producción cómo <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> o <a href="https://github.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>.

Vielleicht möchten Sie ihre Kurse ausprobieren:

* <a href="https://training.talkpython.fm/fastapi-courses" class="external-link" target="_blank">Talk Python Training</a>

     * equality. Two <tt>NtlmPasswordAuthentication</tt> objects are equal if
     * their caseless domain and username fields are equal and either both hashes are external and they are equal or
     * both internally supplied passwords are equal. If one <tt>NtlmPasswordAuthentication</tt> object has external
     * hashes (meaning negotiated via NTLM HTTP Authentication) and the other does not they will not be equal. This is

Wenn Sie das mit Uvicorn ausführen und auf <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a> gehen, sehen Sie die Response von Flask:

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

Und wenn Sie auf <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> gehen, sehen Sie die Response von FastAPI:

```JSON
{

E o resto será manipulado pelo **FastAPI**.

Se você rodar a aplicação e ir até <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a>, você verá o retorno do Flask:

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

E se você for até <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a>, você verá o retorno do FastAPI:

```JSON
{

**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。
