When you import `Query`, `Path` and others from `fastapi`, they are actually functions.

That when called, return instances of classes of the same name.

So, you import `Query`, which is a function. And when you call it, it returns an instance of a class also named `Query`.

These functions are there (instead of just using the classes directly) so that your editor doesn't mark errors about their types.

在这个例子中，你会有：

* `UsersService`

### 客户端方法名 { #client-method-names }

现在，像 `createItemItemsPost` 这样的生成方法名看起来不太简洁：

```TypeScript
ItemsService.createItemItemsPost({name: "Plumbus", price: 5})
```

...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。
