1. On the face of it ,WebService It's an application that exposes itself to the outside world through Web Calling API, In other words, it can be programmed through Web To call this application . We call this WebService Is called the client , And to provide this WebService Is called the server side .

2. At a deeper level ,WebService Is a new platform for building interoperable distributed applications , It's a platform , It's a set of standards . It defines how an application works in Web Interoperability on the Internet , You can use any language you like , Write on any platform you like Web service , As long as we can get through Web service Standards query and access these services .

3.Web Service It's a platform independent , Low coupling , Self contained 、 Based on programmable web Applications for , Open... Can be used XML（ A subset of the standard generic markup language ） Standard to describe 、 Release 、 Find out 、 Coordinate and configure these applications , Applications for developing distributed, interoperable applications . [1]

4.Web Service technology , It can make different applications run on different machines without the aid of additional 、 Specialized third-party software or hardware , You can exchange data or integrate with each other . basis Web Service Between the application of specification implementation , Whatever language they use 、 What is the platform or internal protocol , Can exchange data with each other .Web Service It's self describing 、 Self contained available network modules , Can perform specific business functions .Web Service It's also easy to deploy , Because they are based on some conventional industry standards and some existing technologies , Such as a subset of the standard General Markup Language XML、HTTP.Web Service Reduce the cost of application interface .Web Service It provides a common mechanism for the integration of business processes among the whole enterprise or even multiple organizations .

> Web The three cores of service

• 1、Soap：
  SOAP（Simple Object Access Protocol, Simple object access protocol ） It's based on xml The agreement , Used in step-by-step applications can recognize . in addition ,SOAP There is no programming language defined by itself , This makes SOAP It can be delivered to various remote systems in the form of messages .

  SOAP The transmission protocol used , It can be HTTP,SMTP,POP3,JMS.

  SOAP It includes 4 part ：
  01.“SOAP encapsulation （Envelope）”：

• 2.WSDL：
  WSDL（Web Service Description Language,web Service description language ） It's a XML file , He defines a given in an abstract way independent of the concrete language web Relevant operations and messages of service recipients .

• 3.UDDI：
  UDDI（Universal Description Discovery and Integration, Unified description of discovery and integration protocols ） It's a norm , Defines and web Release of service related information , Discover and manage .

Web Service example

Create in the root directory soap Folder , The file structure is as follows ：

Client.php

<?php
try{
  // non-wsdl Way to call web service
  //  establish  SoapClient  object 
  $soap = new SoapClient(null,array('location'=>"http://localhost/soap/Server.php",'uri'=>'Server.php'));
  //  Call function  
  $result1 = $soap->getName();
  $result2 = $soap->__soapCall("getUrl",array());
  echo $result1."<br/>";
  echo $result2;
} catch(SoapFault $e){
  echo $e->getMessage();
}catch(Exception $e){
  echo $e->getMessage();
}

Server.php

<?php 
// SiteInfo  Class is used to process requests 
Class SiteInfo
{
    /**
     *     Return site name 
     *    @return string 
     *
     */
    public function getName(){
        return " Novice tutorial -test";
    }

    public function getUrl(){
        return "www.runoob.com";
    }
}

//  establish  SoapServer  object 
$s = new SoapServer(null,array("location"=>"http://localhost/soap/Server.php","uri"=>"Server.php"));

//  export  SiteInfo  All the functions in the class 
$s->setClass("SiteInfo");
//  Deal with one SOAP request , Call the necessary functions , And send back a response .
$s->handle();
?>
