定義一個用於權杖端點回應的 Pydantic Model。

建立一個工具函式來產生新的 access token。

{* ../../docs_src/security/tutorial004_an_py310.py hl[4,7,13:15,29:31,82:90] *}

## 更新相依項目 { #update-the-dependencies }

更新 `get_current_user`，讓它仍接收相同的權杖，但這次改用 JWT 權杖。

解碼收到的權杖、驗證它，並回傳目前的使用者。

如果權杖無效，立即回傳一個 HTTP 錯誤。

{* ../../docs_src/security/tutorial004_an_py310.py hl[93:110] *}

## 更新 `/token` 路徑操作 { #update-the-token-path-operation }

- The redirection URI (callback handler) receives the OAuth2 callback, verifies the state parameter, and obtains a Token.
- Using the id_token the callback handler further talks to Google OAuth2 Token URL to obtain an JWT id_token.
- Once obtained the JWT id_token is further sent to STS endpoint i.e MinIO to retrieve temporary credentials.
