〖Linux〗使用gsoap搭建web server（C++）

1. gsoap的好处就不用说了：百度百科

2. gsoap的下载地址：项目地址，目前我使用的是2.8.15版本

3. 开发环境：Ubuntu13.10

4. 具体操作步骤（以简单相加为例）：

　　1）编写add.h（头文件）

//gsoap ns service name: calc

//gsoap ns service protocol: SOAP

//gsoap ns service style: rpc

//gsoap ns service encoding: encoded

//gsoap ns service namespace:    http://localhost:8888

//gsoap ns service location:    http://localhost:8888

//gsoap ns service port:    http://localhost:8888

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

　　2）编写addserver.cpp（服务器）

#include "soapcalcService.h"                    /* 与add.h中第一行ns有关 */

#include "calc.nsmap"                           /* 与add.h中第一行ns有关 */

int main(int argc, char **argv)

{ calcService calc;                             /* 创建calc对象 */

  if (argc < )

    calc.serve();    /* serve as CGI application */

  else

  { int port = atoi(argv[]);

    if (!port)

    { fprintf(stderr, "Usage: server <port>\n");

      exit();

    }

    /* run iterative server on port until fatal error */

    if (calc.run(port))                         /* 运行在port端口上 */

    { calc.soap_stream_fault(std::cerr);

      exit(-);

    }

  }

  return ;

} 

int calcService::add(int a, int b, int *result) /* 在此处实现add() */

{ *result = a + b;

  return SOAP_OK;

}

　　3）编写addclient.cpp（客户端）

#include "soapcalcProxy.h"                      /* 与add.h第一行的ns有关 */

#include "calc.nsmap"                           /* 与add.h第一行的ns有关 */

#include <stdio.h>

#include <stdlib.h>

const char server[] = "127.0.0.1:4567";

int main(int argc, char **argv)

{ if (argc < )

  { fprintf(stderr, "Usage: client num1 num2\n");

    exit();

  }

  int a, b, result;

  a = (int)(strtod(argv[], NULL));             /* str转double再转int */

  b = (int)(strtod(argv[], NULL));

  calcProxy calc;                               /* 创建calc对象 */

  calc.soap_endpoint = server;                  /* 设定server */

  calc.add(a, b, &result);                      /* 执行add() */

  if (calc.error)

    calc.soap_stream_fault(std::cerr);

  else

    printf("result = %d\n", result);            /* 打印消息 */

  return ;

}

　　4）编写Makefile文件

# this is a Makefile to build client and server

# please setting the GSOAP_ROOT first.

# build procedure(EXAMPLE): server run on pc, then client run on arm

#     step1: setting GSOAP_ROOT

#     step2: setting OBJ_NS　　 # the first line in add.h

#     step3: setting OBJ_NAME　 # the basename of filename of add.h

#     step4: setting CC and CXX

#     step4: make

OBJ_NS := calc

OBJ_NAME := add

GSOAP_ROOT := /home/scue/work/gsoap_2.8.15/gsoap

INCLUDE := -I$(GSOAP_ROOT)

CC := clang++

GCC := clang++

#CC := arm-linux-g++

#CXX := arm-linux-g++

CFLAGS += -w

CXXFLAGS += -w

OBJ_SERVER := soapC.o stdsoap2.o soap$(OBJ_NS)Service.o $(OBJ_NAME)server.o

OBJ_CLIENT := soapC.o stdsoap2.o soap$(OBJ_NS)Proxy.o $(OBJ_NAME)client.o

all:

    @make soap

    @make server

    @make client 

server: $(OBJ_SERVER)

    $(CXX) $(CXXFLAGS) $(INCLUDE) $^ -o $@

client: $(OBJ_CLIENT)

    $(CXX) $(CXXFLAGS) $(INCLUDE) $^ -o $@

.PHONY:soap

soap:

    @cp -v $(GSOAP_ROOT)/stdsoap2.* .

    @$(GSOAP_ROOT)/bin/linux386/soapcpp2 -i $(OBJ_NAME).h

soapqt:

    @mkdir -p $(OBJ_NS)qtclient

    @cp -v soapH.h soapStub.h stdsoap2.h soap$(OBJ_NS)Proxy.h \

        soapC.cpp stdsoap2.cpp soap$(OBJ_NS)Proxy.cpp $(OBJ_NS).nsmap \

        $(OBJ_NS)qtclient/

# -c 生成C的文件

# -i 生成C++的文件

.PHONY:clean

clean:

    rm -f server client *.o

distclean:

    rm -f server client *.o ns* soap* *.xml *.nsmap *.wsdl stdsoap2.*

　　5）编译及试验

make

./server

./client   #将会返回5，也可以直接在浏览器中输入http://localhost:4567进行验证

总结：使用C++编写将会轻松很多。
