Linux 平台gsoap简单使用

gsoap下载地址：https://sourceforge.net/projects/gsoap2/?source=typ_redirect

1、编译生成soapcpp2

下载解压之后 跳转gsoap-2.8 目录，执行

./configure

cd gsoap/  执行 make

会在src目录下生成soapcpp2

2、创建test目录

新建add.h 头文件 内容如下

int ns2__add( int num1, int num2, int* sum );

cd test

然后我们执行../src/soapcpp2 -c add.h，自动生成一些远程调用需要的文件。如下所示：

接下来我们写一个服务端，创建文件addserver.c，内容如下：

#include "soapH.h"
#include "add.nsmap"


int main(int argc, char **argv)
{
    int m, s;
    struct soap add_soap;
    soap_init(&add_soap);
    soap_set_namespaces(&add_soap, namespaces);


    if (argc < 2) {
        printf("usage: %s <server_port> \n", argv[0]);
        exit(1);
    } else {
        m = soap_bind(&add_soap, NULL, atoi(argv[1]), 100);
        if (m < 0) {
            soap_print_fault(&add_soap, stderr);
            exit(-1);
        }
        fprintf(stderr, "Socket connection successful: master socket = %d\n", m);
        for (;;) {
            s = soap_accept(&add_soap);
            if (s < 0) {
                soap_print_fault(&add_soap, stderr);
                exit(-1);
            }
            fprintf(stderr, "Socket connection successful: slave socket = %d\n", s);
            soap_serve(&add_soap);
            soap_end(&add_soap);
        }
    }
    return 0;
}


int ns2__add(struct soap *add_soap, int num1, int num2, int *sum)
{
    *sum = num1 + num2;
    return 0;
}

我们接着写客户端，文件addclient.c

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#include "soapStub.h"
#include "add.nsmap"


int add(const char *server, int num1, int num2, int *sum)
{
    struct soap add_soap;
    int result = 0;
 soap_init(&add_soap);
   soap_set_namespaces(&add_soap, namespaces);
    soap_call_ns2__add(&add_soap, server, NULL, num1, num2, sum);
    printf("server is %s, num1 is %d, num2 is %d\n", server, num1, num2);


    if (add_soap.error) {
        printf("soap error: %d, %s, %s\n", add_soap.error, *soap_faultcode(&add_soap), *soap_faultstring(&add_soap));
        result = add_soap.error;
    }
    soap_end(&add_soap);
    soap_done(&add_soap);
    return result;
}

int main(int argc, char **argv)
{
    int result = -1;
    char server[128] = {0};
    int num1;
    int num2;
    int sum;

    if (argc < 4) {
        printf("usage: %s <ip:port> num1 num2 \n", argv[0]);
        exit(1);
    }

    strcpy(server,argv[1]);
    num1 = atoi(argv[2]);
    num2 = atoi(argv[3]);
    result = add(server, num1, num2, &sum);

    if (result != 0) {
        printf("soap error, errcode=%d\n", result);
    } else {
        printf("%d + %d = %d\n", num1, num2, sum);
    }
    return 0;
}

Makefile 文件，注意格式，命令行要以table开始

GSOAP_ROOT = /home/mint/my_work/gsoap/gsoap-2.8/gsoap
WSNAME = add
CC = g++ -g -DWITH_NONAMESPACES
INCLUDE = -I$(GSOAP_ROOT)
SERVER_OBJS = soapC.o stdsoap2.o soapServer.o $(WSNAME)server.o 
CLIENT_OBJS = soapC.o stdsoap2.o soapClient.o $(WSNAME)client.o $(WSNAME)cliento


all: server
server: $(SERVER_OBJS) 
$(CC) $(INCLUDE) -o $(WSNAME)server $(SERVER_OBJS) 


client: $(CLIENT_OBJS) 
$(CC) $(INCLUDE) -o $(WSNAME)client $(CLIENT_OBJS)


cl:
rm -f *.o *.xml *.a *.wsdl *.nsmap soapH.h $(WSNAME)Stub.* $(WSNAME)server ns.xsd $(WSNAME)test

注意：编译的时候我们需要gsoap包里的源代码文件，把上层目录下的stdsoap2.c和stdsoap2.h文件拷贝到当前目录

然后我们执行make，即可生产addserver程序；make client，生成addclient程序。
让server跑起来,执行./addserver 6666

终端打印出“Socket connection successful: master socket = 3”，那么你的server已经在前台run起来了；
运行客户端，./addclient ip:port num1 num2，返回加法的结果。
