发帖数: 5921 | 1 很多job description里面都要求有开发web service的经验，特别是一些金融机构。我
在网上搜了很久，看了一些文章和代码，甚至照着一些教程动手写了些小程序。但还是
云里雾里，觉得始终抓不住要点。甚至如果别人问我什么是web service，我都一下子
答不上来。尽管wiki之类的网站已经看了几十遍了。
向有经验的各位朋友请教一下(尤其是goodbug, briteguy, zhaoce等各位大侠, :))，
究竟什么是web service？如何学习它？能不能推荐一个小project，使得一个有不少编
程经验，但对web这一块没多少实践经验的人能把相关概念融会贯通，从而能尽快地在
工作中完成类似的开发要求？
多谢。 |

http和tcp/ip一定要清楚
尤其是http和tcp/ip之间的关系
现在几乎所有的网络底层协议都是tcp/ip
你会servlet么？
用servlet来写response什么的
不要用框架
把request和response什么弄懂
然后把response里面的html/jsp给换成xml
这是server side
然后在client side，自己用java从main开始写
模拟提交http request
然后接收response
然后弄明白这中间是怎么回事
对比一下web service的一个访问和普通的http访问之间的区别
就大概能够明白是怎么回事了
其实所谓的web service就是客户端把一个xml塞进去
然后再拿到一个xml，xml可以描述你拿到的和发送的是什么东西
当然你也可以不用xml，但是实际上http就已经可以不用html了
你返回什么类型都没问题
web service其实没什么东西，换了一个好听的名字而已
uddi和wsdl之类的就不用看了，了解一下是什么就行了
关键是http, soap, rest, xml, tcp/ip这... 阅读全帖 |

发帖数: 13709 | 3 这个是传输数据的协议
web service的协议则侧重于定义封装数据的格式
所以大部分都是xml
置标语言最初的本意就是用来封装并描述数据的
web service最初的灵感就来自我们天天用的http传送的各种数据
一个request发送过去之后，拿到一个html的response
xml的灵感就来自html，所以最常见的应用就是xhtml这个extension
然后在保留这个传输协议的基础之上，对request和response里面的数据做了定义
最初要求全部用xml来搞，但是群众总是拒绝接受这么复杂的东西
所以有了各种简化版，rest和json就是这种简化版的产物
区别仅仅在于用不用xml而已
web service这个最早是在ieee那个icws上提出来的
我们这边的几所大学在这个领域很活跃 |
