The first change is that now we are declaring the OAuth2 security scheme with two available scopes, `me` and `items`.

The `scopes` parameter receives a `dict` with each scope as a key and the description as the value:

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

Because we are now declaring those scopes, they will show up in the API docs when you log-in/authorize.

    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```


/// info

`**second_user_data` 意思是:

將 `second_user_data` 字典直接作為 key-value 引數傳遞，等同於：`User(id=4, name="Mary", joined="2018-11-30")`

### 多種編輯器支援

整個框架的設計是為了讓使用變得簡單且直觀，在開始開發之前，所有決策都在多個編輯器上進行了測試，以確保提供最佳的開發體驗。

  - `PriorityLevelConfiguration`: the `.spec.limited.nominalConcurrencyShares` field defaults to `30` only if the field is omitted (v1beta3 also defaulted an explicit `0` value to `30`). Specifying an explicit `0` value is not allowed in the `v1` version in v1.29 to ensure compatibility with `v1.28` API servers. In `v1.30`, explicit `0` values will be allowed in this field in the `v1` API.

authentication now supports requiring specific claims with `--oidc-required-claim=<claim>=<value>` Previously, there was no mechanism for a user to specify claims in the OIDC authentication process that were requid to be present in the ID Token with an expected value. This version now makes it possible to require claims support for the OIDC authentication. It allows users to pass in a `--oidc-required-claims` flag, and `key=value` pairs in the API config, which will ensure that the specified required claims...
