204 No Content

HTTP 204 Continue 成功状态响应码表示目前请求成功,但客户端需要继续保留它的现有页面。一个 204 响应在默认是可以被缓存的。响应可以包含头信息ETag

The common use case is to return 204 as a result of a PUT request, updating a resource, without changing the current content of the page displayed to the user. If the resource is created, 201 Created is returned instead. If the page should be changed to the newly updated page, the 200 should be used instead.
