Linux平台下基于C++语言使用gSOAP开发Web Service服务端和客户端程序

4、C++版本的程序:

（1）头文件不变，还是SmsWBS.h

//gsoap ns service name: SmsWBS//gsoap ns service style: rpc//gsoap ns service namespace: http://192.168.1.102:9000/SmsWBS.wsdl//gsoap ns service location: http://192.168.1.102:9000//gsoap ns service encoding: encoded//gsoap ns schema namespace: urn:SmsWBSint ns__add(int num1, int num2, int *sum);

 

（2）编写一个万能的Makefile文件：（此文件稍作改动可以移植到任何工程中）

server := SmsWBSserverclient := SmsWBStest                                                            #your gsoap install directoryGSOAP_DIR=../../gsoap-2.8#web service name,added by dannyWSNAME0=soapSmsWBS                                                            #compilerCORSS_COMPILER = G++ :=$(CORSS_COMPILER)g++                                                            #flagsLIBS:=  -lpthread -lmINCLS := -I ./CFLAGS := -g -O2 -Wall -Wno-deprecated-declarations                                                            #filesWSDL_FILES := SmsWBS.hGSOAP_FILES :=$(WSNAME0)Proxy.cpp $(WSNAME0)Proxy.h $(WSNAME0)Service.h $(WSNAME0)Service.cpp soapC.cpp soapH.h soapStub.hCP_FILES := stdsoap2.h stdsoap2.cppCOM_SOURCES := soapC.cpp  stdsoap2.cppCOM_OBJS := $(COM_SOURCES:.cpp=.o)SERVER_SOURCES := $(server).cpp $(WSNAME0)Service.cppSERVER_OBJS := $(SERVER_SOURCES:.cpp=.o)CLIENT_SOURCES := $(client).cpp $(WSNAME0)Proxy.cppCLIENT_OBJS := $(CLIENT_SOURCES:.cpp=.o)                                                            TYPEMAP = $(wildcard *typemap.dat)ifeq ( , $(TYPEMAP))TYPEMAP = $(GSOAP_DIR)/gsoap/typemap.datendif#MAKE.PHONY: all   all: wsdl gsoap cp $(client) #$(server)                                                            $(server):$(SERVER_OBJS) $(COM_OBJS)$(G++) $(INCLS) $(CFLAGS) -o $@ $^ $(LIBS)$(client):$(CLIENT_OBJS) $(COM_OBJS)$(G++) $(INCLS) $(CFLAGS) -o $@ $^ $(LIBS)$(COM_OBJS) $(CLIENT_OBJS) $(SERVER_OBJS):%.o:%.cpp$(G++) $(INCLS) $(CFLAGS) -o $@ -c $^                                                              wsdl:ifneq ($(WSDL_FILES), $(wildcard $(WSDL_FILES)))$(GSOAP_DIR)/gsoap/bin/linux386/wsdl2h -o $(TYPEMAP) $(wildcard *.wsdl) -o $(WSDL_FILES)endifgsoap:ifneq ($(GSOAP_FILES), $(wildcard $(GSOAP_FILES)))$(GSOAP_DIR)/gsoap/bin/linux386/soapcpp2 -i  $(WSDL_FILES) -I $(GSOAP_DIR)/gsoap/importendifcp:ifneq ($(CP_FILES), $(wildcard $(CP_FILES)))@cp $(GSOAP_DIR)/gsoap/stdsoap2.cpp $(GSOAP_DIR)/gsoap/stdsoap2.h ./ -vendif                                                            #cleanclean:@rm -rfv *.o *~ *Proxy.h *.xml *.nsmap *.a *Object.h soapC.* $(WSNAME0)Service.* $(WSNAME0)Proxy.* $(server) $(client) *.nsmap $(CP_FILES)  $(GSOAP_FILES) 

 

（3）服务端程序SmsWBSserver.cpp：

#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)
{
 *sum = num1 + num2;
 return SOAP_OK;
}

 

以上的C和C++版本的Web Service服务端运行后，在本机或者其它机（windows系统也一样）浏览器中输入http://192.168.1.102:9000/SmsWBS?wsdl，会返回XML文件内容，并返回Web Service的功能函数描述，实现了允许客户端通过http的get操作来获取 SmsWBS.wsdl文件。

部分截屏：

 

（4）客户端程序SmsWBStest.cpp：

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

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]);

        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
