Linux下⽤gSOAP开发WebService服务端和客户端程序
⽹上本有⼀篇流传甚⼴的C版本的，我参考来实现，发现有不少问题，现在根据⾃⼰的开发经验将其修改，使⽤⽆误；另外，补充同样功能的C++版本，我想这个应该更有⽤，因为能⽤C++，当然好过受限于C。
1、gSOAP的安装：
简单安装：
configure --prefix=/usr/local/gSOAP
make
make install
为了后⾯的C和C++版本的服务和客户端的开发能够脱离源代码⽬录，最好还要如下处理：
（1）将源代码⽬录下gsoap⼦⽬录中的import⽬录拷贝到gSOAP⽬录下来；
（2）gSOAP⽬录下建⼀个env⽬录，将gsoap/samples/link下的所有⽂件拷贝过来，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⽬录下建⼀个src⽬录，将将源代码⽬录下gsoap⼦⽬录中的stdsoap*.*拷贝过来。调用webservice服务
2、功能说明：
要开发的Web Service功能⾮常简单，就是⼀个add函数，将两个参数相加，返回其和。
3、C版本的程序:
（1）头⽂件：SmsWBS.h
int ns__add(int num1, int num2, int *sum);
这个头⽂件需要注意的是，前⾯的 // 部分是有意义的，可以在上⾯修改，如果完全去掉，将会导致⽣成的中间⽂件不同，由此会引起要修改Makefile⽂件
（2）Makefile⽂件：
⽐较关键，如果头⽂件中的 // 部分有修改，要检查是否要修改Makefile⽂件

（3）服务端程序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）客户端程序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()
{
printf("soap error:%d, %s, %s ", , *soap_faultcode(&SmsWBS_soap), *soap_faultstring(&SmsWBS_soap));
result = ;
}
soap_end(&SmsWBS_soap);
soap_done(&SmsWBS_soap);
return result;
}
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）编译和运⾏：
前⾯都已经准备好了，现在只需要：
make ---得到服务端程序SmsWBSserver
make client ---得到客户端程序SmsWBStest
SmsWBSserver 9000 ----运⾏服务端程序
出来类似下⾯的显⽰就表⽰运⾏正常
Socket connection successful: master socket = 3
再运⾏客户端程序：
SmsWBStest 67 78
显⽰：
67 + 78 = 145
调⽤Web Service成功

#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)
{

return SOAP_OK;
}
（4）客户端程序SmsWBStest.cpp：
#include <stdio.h>
#include <stdlib.h>
#include "soapSmsWBSProxy.h"
#include "SmsWBS.nsmap"
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续（三）
