PHP Webservice的发布与调用

判官007

　　PHP Webservice的发布与调用
　　1. 环境配置
　　配置php.ini，把php_soap.dll前面的分号去掉，
　　不然会报错
class soapserver not found

　　重启apache后通过phpinfo()查看
　　这样是表示环境已经支持soap的webservice了，后面的事情就是写代码了。

　　2. webservice的发布
　　发布出来的*.wsdl文件，其实是一个xml格式的文件，生成这个文件可以通过第3方软件，如ZendStudio 就可以生成。
　　示例，我用以下代码生成：
<?phpclass CTest{public function __construct(){}/**** @param string $oParams* @return string*/public function Add($oParams){$sParams = $oParams->oParams[l1] ;$oParams = json_decode($sParams);$a = $oParams->a;$b = $oParams->b;$c = $a+$b;return array('AddResult'=>$c);}}?>　　

　　生成的xml文件是：
<?xml version="1.0" encoding="UTF-8" ?> <wsdl:definitions targetNamespace="http://tempuri.org/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:tns="http://tempuri.org/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"><wsdl:types><s:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/"><s:element name="AddRequest"><s:complexType><s:sequence><s:element minOccurs="0" maxOccurs="1" name="oParams" type="s:string" /> </s:sequence></s:complexType></s:element><s:element name="AddResponse"><s:complexType><s:sequence><s:element minOccurs="0" maxOccurs="1" name="AddResult" type="s:string" /> </s:sequence></s:complexType></s:element></s:schema></wsdl:types><wsdl:message name="AddSoapIn"><wsdl:part name="parameters" element="tns:AddRequest" /> </wsdl:message><wsdl:message name="AddSoapOut"><wsdl:part name="parameters" element="tns:AddResponse" /> </wsdl:message><wsdl:portType name="CTestSoap"><wsdl:operation name="Add"><wsdl:input message="tns:AddSoapIn" /> <wsdl:output message="tns:AddSoapOut" /> </wsdl:operation></wsdl:portType><wsdl:binding name="CTestSoap" type="tns:CTestSoap"><soap:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="Add"><soap:operation soapAction="http://tempuri.org/Add" style="document" /> <wsdl:input><soap:body use="literal" /> </wsdl:input><wsdl:output><soap:body use="literal" /> </wsdl:output></wsdl:operation></wsdl:binding><wsdl:binding name="CTestSoap12" type="tns:CTestSoap"><soap12:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="Add"><soap12:operation soapAction="http://tempuri.org/Add" style="document" /> <wsdl:input><soap12:body use="literal" /> </wsdl:input><wsdl:output><soap12:body use="literal" /> </wsdl:output></wsdl:operation></wsdl:binding><wsdl:service name="CTest"><wsdl:port name="CTestSoap" binding="tns:CTestSoap"><soap:address location="http://192.168.6.44:80/webservice/server/server.php?wsdl[l2] " /> </wsdl:port><wsdl:port name="CTestSoap12" binding="tns:CTestSoap12"><soap12:address location="http://192.168.6.44:80/ webservice/server/server.php?wsdl[l3] " /> </wsdl:port></wsdl:service></wsdl:definitions>　　

　　生成xml文件后，就要通过一个服务发布出去，如：
<?phperror_reporting(E_ALL & ~E_DEPRECATED & ~E_NOTICE); include_once('../class/test.class.php');[l4] $server = new SoapServer('wscache/CTest.1.0.wsdl');$server->setClass('CTest');$server->handle();?>　　

　　然后可以向其他人或者系统提供出发布的地址，如：
　　http://192.168.6.44/webservice/server/server.php?wsdl
　　3. webservice的调用
　　通过上面提供的地址，写一个调用页面
<?phperror_reporting(E_ALL & ~E_DEPRECATED & ~E_NOTICE); header("Content-Type: text/html;charset=utf-8");$client = new SoapClient('http://192.168.6.44/webservice/server/server.php?wsdl');$str = '{"a":1,"b":20}';//调用方法一$r = $client->Add(array('oParams'=>$str)); //数组//调用方法二//$pParams->oParams = $str;//$r = $client->__call('Add',array($pParams));//这个得是对象var_dump($r);?>
