Rpc风格的.net服务端代码:
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Xml.Linq;
namespace WebService1
{
[WebService(Namespace = "http://tempuri.org/")]
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
[SoapRpcMethod(Action = "http://tempuri.org/hello", RequestNamespace = "http://tempuri.org/", ResponseNamespace = "http://tempuri.org/")]
public string hello(String s)
{
return "Hello,"+s;
}
}
}
Document风格的.net服务端代码:
namespace WebService1
{
[WebService(Namespace = "http://tempuri.org/")]
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
public string hello(String s)
{
return "Hello,"+s;
}
}
}
java客户端代码:
String url="http://localhost:1117/Service1.asmx";
String namespace = "http://tempuri.org/";
String methodName = "hello";
String soapActionURI = "http://tempuri.org/hello";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL(url));
call.setUseSOAPAction(true);
//这个地方没设对就会出现Server was unable to read request的错误
call.setSOAPActionURI(soapActionURI);
call.setOperationName(new QName(namespace, methodName));
/*
这里如果设置成call.addParameter(new QName(namespace,"s"), XMLType.XSD_STRING,ParameterMode.IN);就是调用document风格的.net服务端如果设反了,.net服务端就接不到参数,接到的是null
*/
call.addParameter("s", XMLType.XSD_STRING, ParameterMode.IN);
call.setReturnType(XMLType.XSD_STRING);
String ret = (String) call.invoke(new Object[] { "kusix" });
System.out.println("返回结果---> " + ret);
如果.net在提供Rpc服务时设置成:[SoapRpcMethod(Action = "",..... 的话,那java客户端中意向的两句可以省略。
call.setUseSOAPAction(true);
call.setSOAPActionURI(soapActionURI);
本文提供了使用.NET编写的RPC和Document两种风格的WebService示例代码,并展示了如何通过Java客户端进行调用。文中详细解释了SOAPAction URI的作用及如何正确设置以避免服务端无法读取请求的问题。
