The response of the `token` endpoint must be a JSON object.

It should have a `token_type`. In our case, as we are using "Bearer" tokens, the token type should be "`bearer`".

And it should have an `access_token`, with a string containing our access token.

For this simple example, we are going to just be completely insecure and return the same `username` as the token.

/// tip

Die Response des `token`-Endpunkts muss ein JSON-Objekt sein.

Es sollte einen `token_type` haben. Da wir in unserem Fall „Bearer“-Token verwenden, sollte der Token-Typ "`bearer`" sein.

Und es sollte einen `access_token` haben, mit einem String, der unseren Zugriffstoken enthält.

In diesem einfachen Beispiel gehen wir einfach völlig unsicher vor und geben denselben `username` wie der Token zurück.

## 返回 Token

`token` 端点的响应必须是 JSON 对象。

响应返回的内容应该包含 `token_type`。本例中用的是**Bearer**Token，因此， Token 类型应为**`bearer`**。

返回内容还应包含 `access_token` 字段，它是包含权限 Token 的字符串。

本例只是简单的演示，返回的 Token 就是 `username`，但这种方式极不安全。

下一章介绍使用哈希密码和 <abbr title="JSON Web Tokens">JWT</abbr> Token 的真正安全机制。

但现在，仅关注所需的特定细节。
