そしてURLは以下です:

```
http://localhost:8000/items/?q=foo&q=bar
```

複数の*クエリパラメータ*の値`q`（`foo`と`bar`）を*path operation関数*内で*関数パラメータ*`q`としてPythonの`list`を受け取ることになります。

そのため、このURLのレスポンスは以下のようになります:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

例如，识别**汽车**或**博客**。

接着，为实体添加权限，比如**驾驶**（汽车）或**编辑**（博客）。

然后，把 JWT 令牌交给用户（或机器人），他们就可以执行驾驶汽车，或编辑博客等操作。无需注册账户，只要有 API 生成的 JWT 令牌就可以。

同理，JWT 可以用于更复杂的场景。

在这些情况下，多个实体的 ID 可能是相同的，以 ID  `foo` 为例，用户的 ID 是 `foo`，车的 ID 是 `foo`，博客的 ID 也是  `foo`。

为了避免 ID 冲突，在给用户创建 JWT 令牌时，可以为 `sub` 键的值加上前缀，例如 `username:`。因此，在本例中，`sub` 的值可以是：`username:johndoe`。

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。
