一. 安装gsoap
下载地址：http://sourceforge.net/projects/gsoap2/files/
解压安装：./configure --prefix=/usr/local/gsoap && make && make install
示例目录：gsoap-2.8/gsoap/samples 有各类语言使用接口方法
async chaining gmt Makefile mashup README.txt udp xml-rpc-json atom chaining++ googleapi Makefile.am mashup++ rest varparam autotest curl hello Makefile.cpp_proxy_rules mtom roll wcf aws databinding httpcookies Makefile.cpp_proxy_rules_j mtom-stream router webserver calc dime link Makefile.cpp_rules oneway rss wsa calc++ dom link++ Makefile.c_rules oneway++ ssl wsrm calc_vs2005 factory lu Makefile.defines polytest template wsse calc_xcode factorytest magic Makefile.in primes testmsgr wst
二. 编写demo
定义函数接口，写chw.h文件
//gsoap ns service name: chw Simple calculator service //gsoap ns service style: rpc //gsoap ns service encoding: encoded //gsoap ns service namespace: //gsoap ns service location: //gsoap ns schema namespace: urn:chw //gsoap ns service method-documentation: add Sums two values int add(int a, int b, int *result); //gsoap ns service method-documentation: sub Subtracts two values int sub(int a, int b, int *result);
使用命令：soapcpp2 -c -x chw.h
-c 产生纯C代码，否则是C++代码(与头文件有关)
-I 指定import路径
-x 不要产生XML示例文件
生成文件有：
[root@Logcen5 test]# ls chw.h soapClient.c soapH.h soapServer.c soapStub.h soapC.c soapClientLib.c soap.nsmap soapServerLib.c
查看soapStub.h文件

SOAP_FMAC5 int SOAP_FMAC6 sub(struct soap*, int a, int b, int *result);
另外需要从gsoap拷贝两个文件过来stdsoap2.c和stdsoap2.h，方便gcc编译不报错！
编写自己的服务端。server.c
#include <stdio.h>
#include "soapH.h"
#include "soap.nsmap"
int main(int argc, char *argv[])
{
struct soap soap;
SOAP_SOCKET m, s;
int ret;
soap_init(&soap);
if (argc < 2)
soap_serve(&soap);
else
{
m = soap_bind(&soap, NULL, atoi(argv[1]), 100);
if (!soap_valid_socket(m))
{
soap_print_fault(&soap, stderr);
exit(-1);
}
fprintf(stderr, "Socket connection successful: master socket = %d
", m);
for ( ; ; )
{
s = soap_accept(&soap);
fprintf(stderr, "Socket connection successful: slave socket = %d
", s);
if (!soap_valid_socket(s))
{
soap_print_fault(&soap, stderr);
exit(-1);
}
soap_serve(&soap);
soap_end(&soap);
}
}
return 0;
}
int add(struct soap *soap, int a, int b, int *result)
{
*result = a + b;
return SOAP_OK;
}
int sub(struct soap *soap, int a, int b, int *result)
{
*result = a - b;
return SOAP_OK;
}
编译命令：gcc -o ser server.c soapC.c soapServer.c stdsoap2.c 生成可执行程序 ser
编写自己的客户端。client.c
#include "soapH.h"
#include "soap.nsmap"
const char server[] = "http://localhost:8888";
int main(int argc, char *argv[])
{
struct soap soap;
int a, b, result;
if (argc < 4)
{
fprintf(stderr, "Usage: [add|sub|mul|div|pow] num num
");
exit(0);
}
a = atoi(argv[2]);
b = atoi(argv[3]);
soap_init(&soap);
switch(*argv[1])
{
case 'a':
//soap_call_ns__add(&soap, server, "", a, b, &result);
soap_call_add(&soap, server, "", a, b, &result);
break;
case 's':
//soap_call_ns__sub(&soap, server, "", a, b, &result);
soap_call_sub(&soap, server, "", a, b, &result);
break;
default:
fprintf(stderr, "Unknown command
");
exit(0);
}
if (soap.error)
{
soap_print_fault(&soap, stderr);
exit(1);
}
else
printf("result = %d
", result);
soap_destroy(&soap);
soap_end(&soap);
soap_done(&soap);
return 0;
}
编译命令：gcc -o cle client.c soapC.c soapClient.c stdsoap2.c生成可执行程序 cle
测试：
在一个窗口执行：./ser 8888
[root@Logcen5 test]# ./ser 8888 Socket connection successful: master socket = 3
另外一个窗口执行：./cle add 2 3
[root@Logcen5 test]# ./cle add 2 3 result = 5
