What is
Sometimes everyone always talks about WebService, so what is it? ?
In the past, there was no application communication standard, which was independent of platform, build model and programming language. Only through the Web Service, the client and the server can communicate freely with HTTP, no matter what the platform and programming language of the two programs are.
So in summary: WebService is a cross-programming language and cross-operating system platform remote call technology.
The so-called cross-programming language and cross-operating platform means that the server program is written in java, and the client program can be written in other programming languages, and vice versa! The cross-operating system platform means that the server program and the client program can run on different operating systems.
The so-called remote call is a method by which a program on a computer a can call an object on another computer b For example, UnionPay provides the POS credit card system for shopping malls, and the code of the transfer method called by the POS machine in the shopping mall actually runs on the bank server. For example, Taobao.com, Schoolnet, Baidu, etc. expose their system services in the form of webservice services, so that third-party websites and programs can call these service functions, which expands the market share of their own systems and expands the concept. Blowing is the so-called SOA application.
