Linux平台下基于C++语言使用gSOAP开发Web Service服务端和客户端程序

4、C++版本的程序:
（1）头文件不变，还是SmsWBS.h

//gsoap ns service name: SmsWBS
//gsoap ns service style: rpc
//gsoap ns service namespace: http://192.168.1.102:9000/SmsWBS.wsdl //gsoap ns service location: http://192.168.1.102:9000 //gsoap ns service encoding: encoded
//gsoap ns schema namespace: urn:SmsWBS

int ns__add(int num1, int num2, int *sum);

（2）编写一个万能的Makefile文件：（此文件稍作改动可以移植到任何工程中）

server := SmsWBSserver
client := SmsWBStest
                                                            
#your gsoap install directory
GSOAP_DIR=../../gsoap-2.8

#web service name,added by danny
WSNAME0=soapSmsWBS

（3）服务端程序SmsWBSserver.cpp：

#include "soapSmsWBSService.h"

#include "SmsWBS.nsmap"

int main(int argc, char **argv)

{

SmsWBSService sms;

if (argc < 2)

sms.serve(); /* serve as CGI application */

else

{

int port = atoi(argv[1]);

if (!port)

{

fprintf(stderr, "Usage: SmsWBSserver++ <port>\n");

exit(0);

}

/* run iterative server on port until fatal error */

if (sms.run(port))

{

sms.soap_stream_fault(std::cerr);

exit(-1);

}

}

return 0;

}

int SmsWBSService::add(int num1, int num2, int *sum)

{

*sum = num1 + num2;

return SOAP_OK;

}



以上的C和C++版本的Web Service服务端运行后，在本机或者其它机（windows系统也一样）浏览器中输入http://192.168.1.102:9000/SmsWBS?wsdl，会返回XML文件内容，并返回Web Service的功能函数描述，实现了允许客户端通过http的get操作来获取 SmsWBS.wsdl文件。

部分截屏：





（4）客户端程序SmsWBStest.cpp：

#include <stdio.h>

#include <stdlib.h>

#include "soapSmsWBSProxy.h"

#include "SmsWBS.nsmap"

int main(int argc, char **argv)

{

int result = -1;

char* server="http://localhost:9000";

int num1 = 0;

int num2 = 0;

int sum = 0;

if( argc < 3 )

{

printf("usage: %s num1 num2 \n", argv[0]);

exit(0);

}

num1 = atoi(argv[1]);

num2 = atoi(argv[2]);

SmsWBSProxy sms;

result = sms.add(num1, num2, &sum);

if (result != 0)

{

printf("soap err, errcode = %d \n", result);

}

else

{

printf("%d + %d = %d \n", num1, num2, sum);

}

return 0;

}

（5）编译运行，与C版本类似，只是服务端运行时没有提示信息
