生成新客户端后，你将拥有**简洁的方法名**，并具备**自动补全**、**内联错误**等功能：

<img src="/img/tutorial/generate-clients/image08.png">

## 优点 { #benefits }

使用自动生成的客户端时，你会获得以下内容的**自动补全**：

* 方法
* 请求体中的数据、查询参数等
* 响应数据

你还会为所有内容获得**内联错误**。

每当你更新后端代码并**重新生成**前端时，新的*路径操作*会作为方法可用，旧的方法会被移除，其他任何更改都会反映到生成的代码中。🤓

   * <p>It is not specified if any performance benefits apply if {@code expectedSize} is close to,

If your **product/company** depends on or is related to **FastAPI** and you want to reach its users, you can sponsor the author (me) through [GitHub sponsors](https://github.com/sponsors/tiangolo). Depending on the tier, you could get some extra benefits, like a badge in the docs. 🎁

產生新的用戶端後，你現在會得到**乾淨的方法名稱**，同時保有所有的**自動完成**、**行內錯誤**等功能：

<img src="/img/tutorial/generate-clients/image08.png">

## 好處 { #benefits }

使用自動產生的用戶端時，你會得到以下項目的**自動完成**：

* 方法
* 本文中的請求有效載荷、查詢參數等
* 回應的有效載荷

你也會對所有內容獲得**行內錯誤**提示。

而且每當你更新後端程式碼並**重新產生**前端（用戶端），新的 *路徑操作* 會以方法形式可用、舊的會被移除，其他任何變更也都會反映到產生的程式碼中。🤓
