建立接口实现类的代码

<?php
 include "SoapDiscovery.php";
 ini_set('soap.wsdl_cache_enabled','0');//关闭缓存
 //注意在开始编程的时候一点要关闭缓存这样的话，更新方法后，client端不会报错
 class Service
 {
     public function Hello()
     {
         return 'hello good';
     }
     public function Add($a,$b)
     {
         return (int)$a+$b;
     }
 }
 $wsdl=new SoapDiscovery('Service','soap');
 //if(isset($_GET['wsdl'])){
 //    header("Content-Type:text/xml; charset=utf-8");
 //    echo file_get_contents("Service.wsdl");
 //   die;  //也可以这么写。   也可以直接在URL中这样webservice.php?wsdl
 //}
 //$wsdl->getWSDL(); 调用或wsdl生成字符串
 $ss = new SoapServer('http://localhost/Service.wsdl');
 $ss->setClass('Service');
 $ss->handle();

然后SoapDoscpvery.php这个wsdl生成类的代码

apache,和nginx中$_SERVER变量信息不太一样， apache 和nignx的主机变量前者$_SERVER['HTTP_HOST']后者$_SERVER['SERVER_HOST']；


soap:address location=\"https://" . $_SERVER['HTTP_HOST'] 。中的协议原来是http 让我改成了https。因为网站是https协议。生成的wsdl的文件是http://www.wkcto.com:443/webservice.php。调用方法会出现地址性的错误

下面是更改后的截图

wsdl.png

声明一个连接的代码。当然连接直向webservice.php?wsdl最好。

推荐使用类库：composer require php2wsdl/php2wsdl

<?php
ini_set('soap.wsdl_cache_enabled','0');//关闭缓存
$soap=new SoapClient('http://localhost/wsdl.php');
//$soap=new SoapClient('http://localhost/webservice.php?wsdl');

$a=$soap->add(1,1);
//echo $soap->_soapCall('Add',array(1,2))//或者这样调用也可以
var_dump($a);

也可以在声明wsdl.php来引入wsdl进行解析，本质上说wsdl就是xml代码

<?php
header("Content-Type:text/xml; charset=utf-8;");
echo file_get_contents("Service.wsdl");

关于Java测试的代码

package testWeb;
 
import java.rmi.RemoteException;
import javax.xml.rpc.ParameterMode;
import javax.xml.rpc.ServiceException;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
 
public class Test {
 public String invokeRemoteFuc() {
 String endpoint = "http://test.solo365.cn/webservice.php?wsdl";
 String result = "no result!";
 Service service = new Service();
 Call call;
 Object[] object = new Object[1];
 object[0] = "Dear I miss you";//Object是用来存储方法的参数
 try {
 call = (Call) service.createCall();
 call.setTargetEndpointAddress(endpoint);// 远程调用路径
 call.setOperationName("Hello");// 调用的方法名
 
 // 设置参数名:
 call.addParameter("str1", // 参数名
 XMLType.XSD_STRING,// 参数类型:String
 ParameterMode.IN);// 参数模式：'IN' or 'OUT'
 
 // 设置返回值类型：
 call.setReturnType(XMLType.XSD_STRING);// 返回值类型：String 
 
 result = (String) call.invoke(object);// 远程调用
 } catch (ServiceException e) {
 e.printStackTrace();
 } catch (RemoteException e) {
 e.printStackTrace();
 }
 return result;
 }
 
 public static void main(String[] args) {
 Test t = new Test();
 String result = t.invokeRemoteFuc();
 System.out.println(result);
 }
}

php的soap无故出错的真凶

wsdl缓存

最近在开发上用到了soap，同时还碰到了一个怪问题。
当我修改了服务端的调用方法后，更新了wsdl，客户端的参数老是丢失（不是全丢失，而是部分），让人很郁闷。

第二天我索性增加了一个服务端的新方法，更新了wsdl，但是客户端请求却报错说没有定义该方法。
最后发现是因为php对soap的wsdl进行了缓存。

解决方法：

**修改php.ini中的soap.wsdl_cache_enabled=1(改为0)，soap.wsdl_cache_ttl=86400(改为0)两项。
特别注意的是，客户端和服务端的机器都要改。**

在Java工具wsimport错误

素包含 use ="encoded" 无法解析 WSDL！

java

原因：本地的jdk 版本是大于1.6 ，jdk1.7以后不再支持这种

解决方法

可以用eclipse工具类操作

操作步骤：

  1. 新建java project
  2. 选中刚才的java project,然后在new web service client ,将wsdl 的路径粘贴上去 。直接finish就可以看到java project 里面有生成的java 代码了。

关于use = "encoded" 几种类型的资料阅读

https://www.cnblogs.com/kaqike/archive/2011/11/06/2238261.html

关于stackoverflow.com 网站上说 是因为这个use ="encoded"这个类型太老了 ，不支持。

在WebXml网站中 用的是 <soap:body use="literal"/>

也就是说jdk版本高不支持。
