1、gSOAP的安裝：

到http:///projects/gsoap2/去下載最新版本，目前是：2.7.15

簡單安裝：

configure --prefix=/usr/local/gSOAP

       make

       make install

為了后面的C和C++版本的服務和客戶端的開發(fā)能夠脫離源代碼目錄，最好還要如下處理：

（1）將源代碼目錄下gsoap子目錄中的import目錄拷貝到gSOAP目錄下來；

（2）gSOAP目錄下建一個env目錄，將gsoap/samples/link下的所有文件拷貝過來，并且生成envC.o（C版本要用到），方法是：

/usr/local/gSOAP/bin/soapcpp2 -penv -c env.h

g++ -c -I /usr/local/gSOAP/include envC.c

（3）gSOAP目錄下建一個src目錄，將將源代碼目錄下gsoap子目錄中的stdsoap*.*拷貝過來。

2、功能說明：

       要開發(fā)的Web Service功能非常簡單，就是一個add函數(shù)，將兩個參數(shù)相加，返回其和。

3、C版本的程序:

（1）頭文件：SmsWBS.h

//gsoap ns service name: SmsWBS
//gsoap ns service style: rpc
//gsoap ns service namespace: http://192.168.1.88:9000/SmsWBS.wsdl
//gsoap ns service location: http://192.168.1.88:9000
//gsoap ns service encoding: encoded
//gsoap ns schema namespace: urn:SmsWBS

int ns__add(int num1, int num2, int *sum);
這個頭文件需要注意的是，前面的 // 部分是有意義的，可以在上面修改，如果完全去掉，將會導致生成的中間文件不同，由此會引起要修改Makefile文件                                           

（2）Makefile文件：

比較關鍵，如果頭文件中的 // 部分有修改，要檢查是否要修改Makefile文件

（3）服務端程序SmsWBSserver.c：

#include "soapH.h"
#include "SmsWBS.nsmap"

int main(int argc, char **argv)
{
        int m, s;               /* master and slave sockets */
        struct soap SmsWBS_soap;

        soap_init(&SmsWBS_soap);

        soap_set_namespaces(&SmsWBS_soap, namespaces);

        if (argc < 2)
        {
                printf("usage: %s <server_port> \n", argv[0]);
                exit(1);
        }
        else
        {
                m = soap_bind(&SmsWBS_soap, NULL, atoi(argv[1]), 100);
                if (m < 0)
                {
                        soap_print_fault(&SmsWBS_soap, stderr);
                        exit(-1);
                }

                fprintf(stderr, "Socket connection successful: master socket = %d\n", m);

                for (;;)
                {
                        s = soap_accept(&SmsWBS_soap);

                        if (s < 0)
                        {
                                soap_print_fault(&SmsWBS_soap, stderr);
                                exit(-1);
                        }

                        fprintf(stderr, "Socket connection successful: slave socket = %d\n", s);
                        soap_serve(&SmsWBS_soap);
                        soap_end(&SmsWBS_soap);
                }

       }

        return 0;
}

int ns__add(struct soap *add_soap, int num1, int num2, int *sum)
{
        *sum = num1 + num2;
        return 0;
}

（4）客戶端程序SmsWBStest.c：

#include <stdio.h>
#include <stdlib.h>
#include "soapStub.h"
#include "SmsWBS.nsmap"

int add(const char *server, int num1, int num2, int *sum);

int add(const char *server, int num1, int num2, int *sum)
{
        struct soap SmsWBS_soap;
        int result = 0;

        soap_init(&SmsWBS_soap);
        soap_set_namespaces(&SmsWBS_soap, namespaces);

        soap_call_ns__add(&SmsWBS_soap, server, "", num1, num2, sum);

        if(SmsWBS_soap.error)
        {
                printf("soap error:%d, %s, %s ", SmsWBS_soap.error, *soap_faultcode(&SmsWBS_soap), *soap_faultstring(&SmsWBS_soap));
                result = SmsWBS_soap.error;
         }

        soap_end(&SmsWBS_soap);
        soap_done(&SmsWBS_soap);

        return result;
}

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]);

        result = add(server, 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）編譯和運行：

前面都已經(jīng)準備好了，現(xiàn)在只需要：

make                                     ---得到服務端程序SmsWBSserver

make client                            ---得到客戶端程序SmsWBStest

SmsWBSserver 9000             ----運行服務端程序

出來類似下面的顯示就表示運行正常

Socket connection successful: master socket = 3

再運行客戶端程序：

SmsWBStest 67 78

顯示：

67 + 78 = 145
