Linux下用gSOAP开发Web Service服务端和客户端程序(一)

2012-07-16 15:18 681 查看

1、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。

2、C版本的程序:

（1）头文件：SmsWBS.h，注释部分不可少，url部分的IP必须填写当前Linux电脑的IP

//gsoap ns service name: SmsWBS

//gsoap ns service style: rpc

//gsoap ns service namespace: http://192.168.2.161:9000/SmsWBS.wsdl

//gsoap ns service location: http://192.168.2.161:9000

//gsoap ns service encoding: encoded

//gsoap ns schema namespace: urn:SmsWBS

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

GSOAP_ROOT=/usr/local/gSOAP

WSNAME0=soap

WSNAME=SmsWBS

CC=g++ -g -DWITH_NONAMESPACES

INCLUDE=-I $(GSOAP_ROOT)/include

SERVER_OBJS=$(WSNAME0)C.o $(WSNAME0)Server.o stdsoap2.o

CLIENT_OBJS=$(GSOAP_ROOT)/env/envC.o $(WSNAME0)ClientLib.o stdsoap2.o

ALL_OBJS=${WSNAME}server.o $(WSNAME0)C.o $(WSNAME0)Server.o ${WSNAME}test.o $(WSNAME0)ClientLib.o

#GSOAP_SRC=/usr/local/gsoap-2.7/gsoap

all:server

${WSNAME}.wsdl:${WSNAME}.h

$(GSOAP_ROOT)/bin/soapcpp2 -c $(GSOAP_ROOT)/import ${WSNAME}.h

stdsoap2.o:$(GSOAP_ROOT)/src/stdsoap2.c

$(CC) -c $? $(INCLUDE)

$(ALL_OBJS):%.o:%.c

$(CC) -c $? $(INCLUDE)

server:Makefile ${WSNAME}.wsdl ${WSNAME}server.o $(SERVER_OBJS)

$(CC) ${WSNAME}server.o $(SERVER_OBJS) -o ${WSNAME}server

client:Makefile ${WSNAME}.wsdl ${WSNAME}test.c $(ALL_OBJS) stdsoap2.o

$(CC) ${WSNAME}test.o $(CLIENT_OBJS) -o ${WSNAME}test

clean:

rm -f *.o *.xml *.a *.wsdl *.nsmap $(WSNAME0)H.h $(WSNAME0)C.c $(WSNAME0)Server.c $(WSNAME0)Client.c $(WSNAME0)Stub.* $(WSNAME)$(WSNAME)Proxy.* $(WSNAME)$(WSNAME)Object.* $(WSNAME0)ServerLib.c $(WSNAME0)ClientLib.c $(WSNAME)server ns.xsd $(WSNAME)test

（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(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）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
