虽然我们才刚刚开始，但其实你已经了解了这一切是如何工作的。

尝试更改下面这行代码：

```Python
    return {"item_name": item.name, "item_id": item_id}
```

......从：

```Python
        ... "item_name": item.name ...
```

......改为：

```Python
        ... "item_price": item.price ...
```

......注意观察编辑器是如何自动补全属性并且还知道它们的类型：

            final LabelTypeItem item = new LabelTypeItem();
            item.setLabel(labelType.getName());
            item.setValue(labelType.getValue());
            item.setPermissions(labelType.getPermissions());
            item.setVirtualHost(labelType.getVirtualHost());
            item.setLocale(labelType.getLocale());
            itemList.add(item);
        }
        labelTypeItemList = itemList;
    }

	case madmin.SRBucketMetaTypeObjectLockConfig:
		err = globalSiteReplicationSys.PeerBucketObjectLockConfigHandler(ctx, item.Bucket, item.ObjectLockConfig, item.UpdatedAt)
	case madmin.SRBucketMetaTypeSSEConfig:
		err = globalSiteReplicationSys.PeerBucketSSEConfigHandler(ctx, item.Bucket, item.SSEConfig, item.UpdatedAt)
	case madmin.SRBucketMetaLCConfig:

    @app.post("/items/")
    def create_item(item: Item):
        return item

    @app.post("/items-list/")
    def create_item_list(item: List[Item]):
        return item

    @app.get("/items/")
    def read_items() -> List[Item]:
        return [
            Item(
                name="Portal Gun",

    else:
        return [{"item_id": "i2", "user_id": user_id}]


@item_router.get("/{item_id}")
def get_item(item_id: str, user_id: Optional[str] = None):
    if user_id is None:
        return {"item_id": item_id}
    else:
        return {"item_id": item_id, "user_id": user_id}
