### Check the docs { #check-the-docs }

Now you can start your app and go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

You will see your docs have the normal *path operations* and now also some **webhooks**:

Але вона буде оброблена функцією-обробником `unicorn_exception_handler`.

Отже, Ви отримаєте зрозумілу помилку зі HTTP-статусом `418` і JSON-відповіддю:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | Технічні деталі

Ви також можете використовувати `from starlette.requests import Request` і `from starlette.responses import JSONResponse`.

Agora vamos revisar essas mudanças passo a passo.

## Esquema de segurança OAuth2 { #oauth2-security-scheme }

A primeira mudança é que agora nós estamos declarando o esquema de segurança OAuth2 com dois escopos disponíveis, `me` e `items`.

O parâmetro `scopes` recebe um `dict` contendo cada escopo como chave e a descrição como valor:

{* ../../docs_src/security/tutorial005_an_py310.py hl[63:66] *}

.github
default.etcd
*.gz
*.tar.gz
*.bzip2
*.zip
browser/node_modules
node_modules
docs/debugging/s3-verify/s3-verify
docs/debugging/xl-meta/xl-meta
docs/debugging/s3-check-md5/s3-check-md5
docs/debugging/hash-set/hash-set
docs/debugging/healing-bin/healing-bin
docs/debugging/inspect/inspect
docs/debugging/pprofgoparser/pprofgoparser

注意，划重点，`sub` 键在整个应用中应该只有一个唯一的标识符，而且应该是字符串。

## 检查

运行服务器并访问文档： <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>。

可以看到如下用户界面：

<img src="https://fastapi.tiangolo.com/img/tutorial/security/image07.png">

用与上一章同样的方式实现应用授权。

使用如下凭证：

用户名: `johndoe` 密码: `secret`

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

Es basiert auf <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, welches wiederum auf der Grundlage von Requests konzipiert wurde, es ist also sehr vertraut und intuitiv.

Damit können Sie <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> direkt mit **FastAPI** verwenden.

## `TestClient` verwenden { #using-testclient }

### Verifique a documentação automática da API { #check-the-automatic-api-docs }

Agora, execute o comando `fastapi` com o seu arquivo:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

E abra a documentação em <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.
