If you use a response class with no media type, FastAPI will expect your response to have no content, so it will not document the response format in its generated OpenAPI docs.

## Check the username { #check-the-username }

Here's a more complete example.

Use a dependency to check if the username and password are correct.

# Body - 更新 { #body-updates }

## 使用 `PUT` 取代式更新 { #update-replacing-with-put }

要更新一個項目，你可以使用 [HTTP `PUT`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT) 操作。

你可以使用 `jsonable_encoder` 將輸入資料轉換為可儲存為 JSON 的資料（例如用於 NoSQL 資料庫）。例如把 `datetime` 轉成 `str`。

{* ../../docs_src/body_updates/tutorial001_py310.py hl[28:33] *}

`PUT` 用於接收應該取代現有資料的資料。

### 關於取代的警告 { #warning-about-replacing }

這表示，如果你想用 `PUT` 並在 body 中包含以下內容來更新項目 `bar`：

)

const (
	// Bucket Encryption configuration file name.
	bucketSSEConfig = "bucket-encryption.xml"
)

// PutBucketEncryptionHandler - Stores given bucket encryption configuration
// https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketEncryption.html
func (api objectAPIHandlers) PutBucketEncryptionHandler(w http.ResponseWriter, r *http.Request) {
	ctx := newContext(r, w, "PutBucketEncryption")

## Caveat { #caveat }

If you need to perform heavy background computation and you don't necessarily need it to be run by the same process (for example, you don't need to share memory, variables, etc), you might benefit from using other bigger tools like [Celery](https://docs.celeryq.dev).
