A.REST服务比SOAP和XML-RPC更为简洁,可以完全通过HTTP协议实现,还可以利用缓存Cache来提高响应速度,性能、效率和易用性上都优于SOAP协议。
B.REST服务中的资源所指的不是数据,而是数据和表现形式的组合,可以是图片,Word、文件,甚至可以是一种虚拟的服务,所有的服务资源都可以通过URL进行唯一标识。

He was young and completely unknown, but Paul Waterhouse believed in himself. He'd heard that there was going to be a large exhibition for jewellery designers and he asked the organisers whether he could show some of his work. 'I was only 21,' he says, 'and they agreed, if I could show a complete collection.' So he went to the bank, borrowed £1,500 for materials, and began to work on new designs. 'The exhibition was fantastic. Although everyone else was much more experienced than I was, my designs were still praised.'
He decided to transfer his business to Canada and began to experiment with new materials: all sorts of stones from around the world, some totally new to him. 'As most of them weren't precious, it changed the way I approached design. It was great! I was able to produce much larger pieces of modern jewellery,' he says. 'Then I was asked by an advertising agency to design a wedding ring for a TV advert. The agency liked what I'd done, but their client, a car manufacturer, wanted something a little more traditional. I was happy to make changes and that work gave me a lot of free publicity.'
At the start of his career, Paul felt confident.
A.Right
B.Wrong
C.Doesn't say
