PHP调用webservice接口笔记_php 调用webservice接口开发

1、【开启php_soap.dll扩展】

找到php.ini文件
；extension=php_soap.dll

删除掉"；" ，重启apache服务器

2、【下载SoapDiscovery.class.php类】

这个类库文件直接网上搜索就有了，代码如下：

    }  
}  
  
?>  

3、【生成wsdl文件】

创建文件server.php，代码如下：

<?php
define('WSDL_URL','Test.wsdl');        //定义WSDL文件路径
ini_set('soap.wsdl_cache_enabled','0');    //关闭WSDL缓存
 
 //WSDL文件不存在时自动创建
if(!file_exists(WSDL_URL))
{
    require_once 'SoapDiscovery.class.php';
    $disco = new SoapDiscovery('Test','domainName');/* domainName为你的域名，可以随便写 */
    $disco->getWSDL();
}
 
//SOAP开启并接收Client传入的参数响应 
$server = new SoapServer(WSDL_URL);
$server->setClass('Test');
$server->handle();
 
/* 测试类 */
class Test {
    public function hello($name = '') 
    {
        return 'Hello '.$name.'.';
    }
}

运行server.php文件，即可生成Test.wsdl文件，如下：

<?xml version="1.0" ?>
<definitions name="domainName" targetNamespace="urn:domainName" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="urn:domainName" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns="http://schemas.xmlsoap.org/wsdl/">
<types xmlns="http://schemas.xmlsoap.org/wsdl/" />
<portType name="domainNamePort"><operation name="hello">
<input message="tns:helloRequest" />
<output message="tns:helloResponse" />
</operation>
</portType>
<binding name="domainNameBinding" type="tns:domainNamePort">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />
<operation name="hello">
<soap:operation soapAction="urn:domainName#Test#hello" />
<input><soap:body use="encoded" namespace="urn:domainName" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
</input>
<output>
<soap:body use="encoded" namespace="urn:domainName" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
</output>
</operation>
</binding>
<service name="domainName">
<documentation />
<port name="domainNamePort" binding="tns:domainNameBinding"><soap:address location="http://localhost/server.php" />
</port>
</service>
<message name="helloRequest">
<part name="name" type="xsd:string" />
</message>
<message name="helloResponse">
<part name="hello" type="xsd:string" />
</message>
</definitions>

Test.wsdl文件中比较关键的地方用颜色标出来了，建议大家自己生成下，不要直接复制。

4、【调用接口】

创建client.php，代码如下：

<?php 
$client = new SoapClient("http://localhost/server.php?wsdl", array('trace' => 1));/* 创建soapclient对象 */
 
try {
    $result = $client->hello('man');/* 调用方法 */
    var_dump($result);
} catch (SoapFault $f){
    echo '__getFunctions = ';
    var_dump($client->__getFunctions());
    echo '<br/>-----------------------<br/>';
    echo '__getLastRequest = '.$client->__getLastRequest();
    echo '<br/>-----------------------<br/>';
    echo '__getLastResponse = '.$client->__getLastResponse();
    echo '<br/>-----------------------<br/>';
    echo "Error Message: {$f->getMessage()}";
}
?>

完成。
