OpenAPI 要求每個操作 ID 在所有 *路徑操作* 之間必須唯一，因此 FastAPI 會用**函式名稱**、**路徑**與 **HTTP 方法/操作**來產生該操作 ID，如此便能確保操作 ID 的唯一性。

接下來我會示範如何把它變得更好看。🤓

## 自訂 Operation ID 與更好的方法名稱 { #custom-operation-ids-and-better-method-names }

你可以**修改**這些操作 ID 的**產生方式**，讓它們更簡潔，並在用戶端中得到**更簡潔的方法名稱**。

在這種情況下，你需要用其他方式確保每個操作 ID 都是**唯一**的。

例如，你可以確保每個 *路徑操作* 都有標籤，接著根據**標籤**與 *路徑操作* 的**名稱**（函式名稱）來產生操作 ID。

Also, **automatically generated clients** will have simpler interfaces, so that the developers communicating with your API can have a much better time working with your API. 😎
