C++与Java的webservice通信方式实现

C++与Java的一种webservice通信方式实现记录直接分享了.  代码工程

C++采用gsoap库来实现的,在gsoap的SDK中可以找到两个将接口生成代码框架的工具,soapcpp2.exe  wsdl2h.exe

服务端例子add.h

//gsoap ns service name: add
//gsoap ns service namespace: http://localhost/add.wsdl
//gsoap ns service location: http://localhost
//gsoap ns service executable: add.cgi
//gsoap ns service encoding: encoded
//gsoap ns schema namespace: urn:add

int ns__add(int a, int b, int *result);
int ns__sub(double a, double b, double *result);
int ns__mul(double a, double b, double *result);
int ns__div(double a, double b, double *result);
int ns__pow(double a, double b, double *result);
//int ns__checkLogin(char* Name,char* Pass, bool *result);
//int ns__TestShow(int *id, char* *result);
int ns__ClsP(int *result);
int ns__HahaKd(int *result);  
int ns__EndExe(char* Name, int *result); 
int ns__StartExe(char* Name, int *result);

服务端代码:

#include "DCSoap.h"
//输出DBdata的soap
//#include "Soap/soapH.h"
//#include "Soap/DBdata.h"
//输出add的soap
/*#include "lib/add.nsmap"*/
#include "../Soap/soapH.h"
#include "../Soap/add.h"

#include <iostream>

生成wsdl接口文件的方法:

rem wsdl2h.exe: 编译wsdl文件生成c/c++头文件
rem -o 文件名，指定输出头文件 
rem -n 名空间前缀 代替默认的ns 
rem -c 产生纯C代码，否则是C++代码 
rem -s 不要使用STL代码 
rem -t 文件名，指定type map文件，默认为typemap.dat 
rem -e 禁止为enum成员加上名空间前缀
rem soapcpp2.exe: gSOAP编译器，
rem 编译头文件生成服务器和客户端都需要的c/c++文件
rem -C 仅生成客户端代码 
rem -S 仅生成服务器端代码 
rem -L 不要产生soapClientLib.c和soapServerLib.c文件 
rem -c 产生纯C代码，否则是C++代码(与头文件有关) 
rem -I 指定import路径（见上文） 
rem -x 不要产生XML示例文件 
rem -i 生成C++包装，客户端为xxxxProxy.h(.cpp)，服务器端为xxxxService.h(.cpp)

attrib +r +h +s add.cpp
attrib +r +h +s add.h
del *.xml
del *.o
del *.h
del *.cpp
del *.nsmap
del *.xsd
del *.wsdl
rd /s /q client
rem 生成服务端代码
rem gsoap\bin\win32\soapcpp2.exe  -S -I gsoap\import Csoap\lib\add.h
gsoap\bin\win32\soapcpp2.exe add.h
rem gsoap\bin\win32\soapcpp2.exe -i add.h

rem 生成客户端代码
md client
copy /Y add.h .\client\
rem gsoap\bin\win32\wsdl2h.exe -o client\add.h add.wsdl
rem #gsoap\bin\win32\soapcpp2.exe -C -I gsoap\import client\add.h
rem #gsoap\bin\win32\wsdl2h.exe -o add.h ..\..\exe\add.wsdl
attrib -r -h -s add.cpp
attrib -r -h -s add.h
@copy /Y add.wsdl ..\exe\
pause

这里客户端请求 我还是用C++代码(java的应该很常见了) 

客户端就是拿到wsdl接口文件去生成代码了

@echo off

@echo off

cls
@echo on
copy /Y ..\..\exe\add.wsdl .\add.wsdl

..\..\Soap\gsoap\bin\win32\soapcpp2.exe  -C -I ..\..\Soap\gsoap\import add.h
pause

客户端调用例子

// SoapClientConsole.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include "SoapClient/soapH.h"
#include "SoapClient/soapStub.h"
#include "SoapClient/add.nsmap"
#include <string>
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	//int ns__add(int a, int b, int *result);
	struct soap TestSoap;
	soap_init(&TestSoap);
	int result = -1;
	_ns2__add input;
	input.a = 1;
	input.b = 1;
	input.soap = &TestSoap;
	_ns2__addResponse output;
	output.soap = &TestSoap;

	soap_call___ns1__add(&TestSoap,"http://127.0.0.1:80?wsdl",NULL,&input,&output);     //"http://127.0.0.1:80?wsdl"

	if(TestSoap.error)
	{
		printf("soap error:%d,%s,%s\n", TestSoap.error, *soap_faultcode(&TestSoap), *soap_faultstring(&TestSoap) );
		result = TestSoap.error;
	} 
	else
	{
		cout<<"Return     = "<<*output.result<<endl;
	}

	soap_end(&TestSoap);
	soap_done(&TestSoap);
	system("pause");
	return 0;
}

最后运行测试一下  只要IP对上跨机器通信也好使了.
