webservice-一种xml数据交换格式

代码地址

git clone https://gitee.com/yanglingyun/webservice_learn.git

概念

• 以xml形式交换数据

php实现

php.ini开启soap

php7.3.4

extension=soap

测试调用

<?php
// 利用soapclient
$soapclient = new SoapClient('http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx?wsdl');
// 客户端通过wsdl，了解webservice可调用方法与参数细节
// print_r($soapclient->__getFunctions());// 获得调用方法
print_r($soapclient->getMobileCodeInfo(array('mobileCode'=>'13426060134')));
 获得调用方法

得

Array ( [0] => getRegionDatasetResponse getRegionDataset(getRegionDataset $parameters) [1] => getRegionProvinceResponse getRegionProvince(getRegionProvince $parameters) [2] => getRegionCountryResponse getRegionCountry(getRegionCountry $parameters) [3] => getSupportCityDatasetResponse getSupportCityDataset(getSupportCityDataset $parameters) [4] => getSupportCityStringResponse getSupportCityString(getSupportCityString $parameters) [5] => getWeatherResponse getWeather(getWeather $parameters) [6] => getRegionDatasetResponse getRegionDataset(getRegionDataset $parameters) [7] => getRegionProvinceResponse getRegionProvince(getRegionProvince $parameters) [8] => getRegionCountryResponse getRegionCountry(getRegionCountry $parameters) [9] => getSupportCityDatasetResponse getSupportCityDataset(getSupportCityDataset $parameters) [10] => getSupportCityStringResponse getSupportCityString(getSupportCityString $parameters) [11] => getWeatherResponse getWeather(getWeather $parameters) )

数组传参调用

print_r($soapclient->getMobileCodeInfo(array('mobileCode'=>'13426060134')));

搭建webservice服务

WSDL服务描述文档

<?xml version='1.0' encoding='UTF-8'?><wsdl:definitions name="HelloWorldService" targetNamespace="http://soap.com" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://soap.com" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <wsdl:types>
<xs:schema targetNamespace="http://soap.com"  xmlns:xs="http://www.w3.org/2001/XMLSchema">

</xs:schema>
  </wsdl:types>
  <!-- add的消息（相当于类有一个add方法） -->
	<wsdl:message name="sumReq">
		<!-- 消息里面包含add对象(相当于类中要传入的值) -->
		<wsdl:part type="xsd:string" name="item" />
	</wsdl:message>
	<!-- add的返回消息相当于return -->
	<wsdl:message name="sumRes">
		<wsdl:part type="xsd:string" name="value" />
	</wsdl:message>
  <wsdl:portType name="oplist">
    <wsdl:operation name="sum">
      <wsdl:input message="tns::sumReq"/>
      <wsdl:output message="tns::sumRes"/>
    </wsdl:operation>
  </wsdl:portType>
<wsdl:binding name="cartWsBi" type="tns:oplist">
    <soap:binding style="document"
			transport="http://schemas.xmlsoap.org/soap/http" />

		<wsdl:operation name="sum">
			<wsdl:input>
				<soap:body use="literal" />
			</wsdl:input>
			<wsdl:output>
				<soap:body use="literal" />
			</wsdl:output>
		</wsdl:operation>
  </wsdl:binding>
<wsdl:service name="shop">
    <wsdl:port binding="tns:cartWsBi" name="cartWs">
      <soap:address location="http://soap.com/service.php"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

处理函数service.php

<?php
function sum($str){
    return 'webservice' . $str;
}
$server = new soapServer('http://soap.com/wsdl.xml'); 
$server->addFunction('sum');// 注册
$server->handle();

请求文件client.php

<?php
// 利用soapclient
$soapclient = new SoapClient('http://soap.com/wsdl.xml');
// 客户端通过wsdl，了解webservice可调用方法与参数细节
// print_r($soapclient->__getFunctions());// 获得调用方法
print_r($soapclient->sum('13426060134'));

搭建xml_rpc服务

简化soap，对参数包装简单

php.ini开启php_xmlrpc

extension=xmlrpc

创建rpc服务器

<?php
function hello($str){
    return 'hello world'.$str;
}
$server = xmlrpc_server_create();
// 注册用户函数入服务器 参数: 服务器 注册函数名 注册后函数名
xmlrpc_server_register_method($server,'hello','hello');
// 收取POST请求 内容为xml
$req = $HTTP_RAW_POST_DATA;
// 响应用户
$res = xmlrpc_server_call_method($server, $req, null);
// 输出
header('content-type:text/xml');
echo $res;
// 销毁服务器
xmlrpc_server_destroy($server);

rpc请求

<?php
class rpcclient {
    protected $url;
    public function __construct($url)
    {
        $this->url = $url;
    }
    protected function __query($req){
      
        $context = stream_context_create(
          array(
                'http'=>array(
                    'method'=>'POST',//大写必须
                'header'=>'content-type:text/xml',
                'content'=>$req
                )
            )
            
            );
            
            return xmlrpc_decode(file_get_contents($this->url, false,$context));
    }
    public function __call($method, $args)
    {
        $req = xmlrpc_encode_request($method, $args);
        return $this->__query($req);
    }
}
$client  = new rpcclient('http://soap.com/rpc-server.php');
print_r($client->hello());
