首先，要关注的是依赖项。

依赖项就是一个函数，且可以使用与*路径操作函数*相同的参数：

```Python hl_lines="8-11"
{!../../docs_src/dependencies/tutorial001.py!}
```

大功告成。

只用了**2 行**代码。

依赖项函数的形式和结构与*路径操作函数*一样。

因此，可以把依赖项当作没有「装饰器」（即，没有 `@app.get("/some-path")` ）的路径操作函数。

依赖项可以返回各种内容。

本例中的依赖项预期接收如下参数：

* 类型为 `str` 的可选查询参数 `q`
* 类型为 `int` 的可选查询参数 `skip`，默认值是 `0`
* 类型为 `int` 的可选查询参数 `limit`，默认值是 `100`

然后，依赖项函数返回包含这些值的 `dict`。

func (target *KafkaTarget) SendFromStore(key store.Key) (err error) {
	if err = target.init(); err != nil {
		return err
	}
	switch {
	case key.ItemCount == 1:
		var event event.Event
		event, err = target.store.Get(key)
		if err != nil {
			// The last event key in a successful batch will be sent in the channel atmost once by the replayEvents()
			// Such events will not exist and wouldve been already been sent successfully.
