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.

	}

	unlockReturned := make(chan struct{}, 1)
	go func() {
		ctx, cancel := context.WithTimeout(context.Background(), 500*time.Millisecond)
		defer cancel()
		dm.Unlock(ctx)
		// Unlock is not blocking. Try to get a new lock.
		dm.GetLock(ctx, nil, id, source, Options{Timeout: 5 * time.Minute})
		unlockReturned <- struct{}{}
	}()

	timer := time.NewTimer(2 * testDrwMutexUnlockCallTimeout)
	defer timer.Stop()

	files, _ := filepath.Glob(filepath.Join(diskPath, ".writable-check-*.tmp"))
	for _, file := range files {
		go removeAll(file)
	}

	// Remove the entire folder in case there are leftovers that didn't get cleaned up before restart.
	go removeAll(pathJoin(diskPath, minioMetaTmpBucket+"-old"))

	// Renames and schedules for purging all bucket metacache.
	go renameAllBucketMetacache(diskPath)
}

```Python
results = await some_library()
```

Entonces declara tus *path operation functions* con `async def` de la siguiente manera:

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

/// note | Nota

Solo puedes usar `await` dentro de funciones creadas con `async def`.

// Wrapper for calling Create Bucket and ensure we get one and only one success.
func TestCreateBucket(t *testing.T) {
	ExecObjectLayerAPITest(ExecObjectLayerAPITestArgs{t: t, objAPITest: testCreateBucket, endpoints: []string{"MakeBucket"}})
}

// testCreateBucket - Test for calling Create Bucket and ensure we get one and only one success.

		// differently on each nodes, update skipEnvs()
		// map if there are such environment values
		if _, ok := skipEnvs[envK]; ok {
			continue
		}
		envValues[envK] = logger.HashString(env.Get(envK, ""))
	}
	scfg := &ServerSystemConfig{NEndpoints: globalEndpoints.NEndpoints(), MinioEnv: envValues, Checksum: binaryChecksum}
	var cmdLines []string
	for _, ep := range globalEndpoints {

The following example shows how to get the details of the user with `{userid}` from `{realm}` realm:

```
curl \
  -H "Authorization: Bearer eyJhbGciOiJSUz..." \
  "http://localhost:8080/auth/admin/realms/{realm}/users/{userid}"
```
