Web 服务是无状态的? [英] Webservices are stateless?

问题描述

为什么我们说 Web 服务是无状态的?

Why do we say that web services are stateless?

推荐答案

它们不会在来自客户端的请求之间保持任何状态.即服务不知道，也不关心，后续请求来自已经/没有提出过先前请求的客户端.基本上，它是给我这条信息并忘记我"，这让客户端有责任维护任何状态.

They don't persist any state between requests from the client. i.e. the service doesn't know, nor care, that a subsequent request came from client that has/hasn't made a previous request. Basically, its a 'give me this piece of info and forget about me' which puts the onus on the client to maintain any state.
