推荐答案

你提到的技术差异很大，我们谈论的是REST metaphers。

There's the technically differences you mentioned and there's part where we're talking about REST metaphers.

除了POST和GET之外，还有PUT和DELETE。您应该将GET用于不改变数据的操作，POST用于创建，PUT用于更新数据。 DELETE显然是删除数据。

Beside POST and GET, there's PUT and DELETE too. You should use GET for operations which don't alter your data, POST for creation and PUT for update of data. DELETE is obviously for deletion of data.
