推荐答案

什么是网络服务

事情很多.在编程中，in 一般是指一个网页，可以从应用程序(可以是另一个网页，或桌面应用程序)调用，调用者将向其传递数据，或从中接收数据.

It is many things. In programming, in generally refers to a web page, that can be called from an application (be it another web page, or desktop app), and the caller will pass in data to it, or receive data from it.

从这个意义上说，它基本上就像普通编程语言中的方法"或函数"；除非你是通过互联网调用它.

In this sense, it's basically like a 'method' or 'function' in a normal programming language; except you're calling it over the internet.

SOAP

一种消息格式.如上所述，Web 服务基本上是一种方法"或功能".SOAP 是此方法的指令"和数据".它将概述数据类型，可能还有一堆数据.它是一种 XML 格式.

A message format. As discussed above, a web service is a basically a 'method' or 'function'. SOAP is the 'instructions' and 'data' to this method. It will outline data types, and possibly a bunch of data as well. It is an XML format.

REST 是实现应用程序接口但是、实现访问控制和其他类似事情的方法，特别是使用 HTTP 响应代码.因此，如果您没有访问权限，您将收到 401: Denied(我认为这是正确的代码).还有其他类型的响应代码很有用.它还使用其他 HTTP 命令，如 PUT/HEAD/OPTIONS.

REST is the means of implementing an interface to your application but, implementing access control, and other such things, specifically with HTTP Response codes. So you will get a 401: Denied (I think that's the right code), if you don't have access. There are other types of response codes that are useful. It also makes use of other HTTP commands like PUT/HEAD/OPTIONS.
