这样，只编写一次代码，**FastAPI** 就可以为多个*路径操作*共享这段代码 。

/// check | "检查"

注意，无需创建专门的类，并将之传递给 **FastAPI** 以进行「注册」或执行类似的操作。

只要把它传递给 `Depends`，**FastAPI** 就知道该如何执行后续操作。

///

## 要不要使用 `async`？

**FastAPI** 调用依赖项的方式与*路径操作函数*一样，因此，定义依赖项函数，也要应用与路径操作函数相同的规则。

func isMaxObjectSize(size int64) bool {
	return size > globalMaxObjectSize
}

// Check if part size is more than or equal to minimum allowed size.
func isMinAllowedPartSize(size int64) bool {
	return size >= globalMinPartSize
}

// isMaxPartNumber - Check if part ID is greater than the maximum allowed ID.
func isMaxPartID(partID int) bool {
	return partID > globalMaxPartID
}

  - Add this Role into compositive role named `default-roles-{realm}` - `{realm}` should be replaced with whatever realm you created from `prerequisites` section. This role is automatically trusted in the 'Service Accounts' tab.

- Check that `account` client_id has the role 'admin' assigned in the "Service Account Roles" tab.

After that, you will be able to obtain an id_token for the Admin REST API using client_id and client_secret:
