在高级使用场景中，如果不想使用「缓存」值，而是为需要在同一请求的每一步操作（多次）中都实际调用依赖项，可以把 `Depends` 的参数 `use_cache` 的值设置为 `False` :

```Python hl_lines="1"
async def needy_dependency(fresh_value: str = Depends(get_value, use_cache=False)):
    return {"fresh_value": fresh_value}
```

## 小结

千万别被本章里这些花里胡哨的词藻吓倒了，其实**依赖注入**系统非常简单。

依赖注入无非是与*路径操作函数*一样的函数罢了。

					sorted = append(sorted[:sortedIdx], append([]string{c.name}, sorted[sortedIdx:]...)...)
				} else if curIdx > sortedIdx {
					return fmt.Errorf("conflicting callback %s with before %s", c.name, c.before)
				}
			} else if idx := getRIndex(names, c.before); idx != -1 {
