In the next chapter, you will see a real secure implementation, with password hashing and <abbr title="JSON Web Tokens">JWT</abbr> tokens.

But for now, let's focus on the specific details we need.

///

{* ../../docs_src/security/tutorial003_an_py310.py hl[87] *}

/// tip

By the spec, you should return a JSON with an `access_token` and a `token_type`, the same as in this example.

En el próximo capítulo, verás una implementación segura real, con hashing de passwords y tokens <abbr title="JSON Web Tokens">JWT</abbr>.

Pero por ahora, enfoquémonos en los detalles específicos que necesitamos.

# OAuth2 com Senha (e hashing), Bearer com tokens JWT { #oauth2-with-password-and-hashing-bearer-with-jwt-tokens }

Agora que temos todo o fluxo de segurança, vamos tornar a aplicação realmente segura, usando tokens <abbr title="JSON Web Tokens">JWT</abbr> e hashing de senhas seguras.

Este código é algo que você pode realmente usar na sua aplicação, salvar os hashes das senhas no seu banco de dados, etc.

Vamos começar de onde paramos no capítulo anterior e incrementá-lo.

## 回傳 token { #return-the-token }

`token` 端點的回應必須是 JSON 物件。

它應該有一個 `token_type`。在本例中，我們使用「Bearer」tokens，token 類型應該是「`bearer`」。

而且它還應該有一個 `access_token`，其值為包含我們存取權杖的字串。

在這個簡單示例中，我們會不安全地直接回傳相同的 `username` 當作 token。

下一章你會看到真正安全的實作，包含密碼雜湊與 <abbr title="JSON Web Tokens - JSON 網頁權杖">JWT</abbr> tokens。

但現在先把注意力放在我們需要的這些細節上。

Previously, site replication required the root credentials of peer sites to be identical. This is no longer necessary because STS tokens are now signed with the site replicator service account credentials, thus allowing flexibility in the independent management of root accounts across sites and the ability to disable root accounts eventually.
