在flux架构中，谁负责向服务器发送更新? [英] In the flux architecture, who is responsible for sending updates to the server?

问题描述

所以在flux架构中，数据流如下:

So in the flux architecture, data flows as follows:

View -> Action -> Dispatcher -> Store
 ^ <-----------------------------|

所以假设视图是一个评论框.当用户提交评论时，会触发 addComment 操作，但是该评论应该发送到服务器的哪里呢?它应该发生在动作函数中，在调度它之前，还是应该在从调度器接收到动作时存储?

So let's say the view is a comment box. When the user submits a comment, an addComment action is triggered, but where should that comment be sent to the server? Should it happen in the action function, before dispatching it, or should the store doing it when receiving the action from the dispatcher?

这两种情况似乎都违反了单一职责模式.或者应该有两个 CommentStores，一个 LocalCommentStore 和一个 ServerCommentStore 来处理 addComment 操作?

Both cases seam like a violation of the single responsibility pattern. Or should there be two CommentStores, one LocalCommentStore and a ServerCommentStore that both handle the addComment action?

推荐答案

在您的情况下，Action 负责向商店发送待处理操作或乐观更新以及向 WebAPI 发送调用:

In your case Action is responsible for both sending a pending action or optimistic update to the store and sending a call to the WebAPI:

View -> Action -> Pending Action or optimistic update  -> Dispatcher -> Store -> emitEvent -> View 
               -> WebUtils.callAPI()

onWebAPISuccess -> Dispatcher -> Store -> emitEvent -> View
onWebAPIFail -> Dispatcher -> Store -> emitEvent -> View
