So, to avoid ID collisions, when creating the JWT token for the user, you could prefix the value of the `sub` key, e.g. with `username:`. So, in this example, the value of `sub` could have been: `username:johndoe`.

The important thing to keep in mind is that the `sub` key should have a unique identifier across the entire application, and it should be a string.

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。
