...这是因为客户端生成器会把每个*路径操作*的 OpenAPI 内部**操作 ID（operation ID）**用作方法名的一部分。

OpenAPI 要求每个操作 ID 在所有*路径操作*中都是唯一的，因此 FastAPI 会使用**函数名**、**路径**和**HTTP 方法/操作**来生成操作 ID，以确保其唯一性。

接下来我会告诉你如何改进。🤓

## 自定义操作 ID 与更好的方法名 { #custom-operation-ids-and-better-method-names }

你可以**修改**这些操作 ID 的**生成**方式，使之更简单，从而在客户端中得到**更简洁的方法名**。

在这种情况下，你需要用其他方式确保每个操作 ID 依然是**唯一**的。

例如，你可以确保每个*路径操作*都有一个标签，然后基于**标签**和*路径操作***名称**（函数名）来生成操作 ID。

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。
