何时使用doGet，doPost和服务

问题描述

我想知道这些servlet方法。我对这些方法有所了解，比如

I was wondering about these servlet methods. i know something about these methods like

• doPost 对参数数字没有限制 doGet has。


• doGet 快于 doPost 。


• doPost 比 doGet 。



• doPost has no limitations on paramater numbers while doGet has.

And my question is, as these methods takes same parameters and does the process which we implement. then what is the major difference between these methods and At which specific situation each of this method is used to process.

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.
