gSOAP嵌入式linux下的移植与程序开发

一、移植

       1、下载源码

　　

　　    本例下载最新版本为：gsoap_2.8.33.zip

　　2、解压源码

　　   $ unzip gsoap_2.8.33.zip
      3、平台准备unbuntu1204
          $sudo apt-get install build-essential

　　    $sudo apt-get install libgtk2.0-dev libglib2.0-dev

　　    $sudo apt-get install checkinstall
          $sudo apt-get install flex bison
          $sudo apt-get install openssl
          $sudo apt-cache search libssl | grep SSL
          $sudo apt-get install libssl-dev

　　4、编译x86 平台下工具

　　$ ./configure --prefix=/usr/local/gsopa-x86

　　$ make

　　$ make install
      $ export PATH=/usr/local/gSOAP-x86/bin:$PATH

　　5、编译arm平台工具

　　./configure --prefix=/usr/local/gsopa-arm --host=arm-linux

　　再次配置源码，这次配置目标平台变为arm-linux

　　修改源码，根据编译错误提示进行适当修改：

　　修改源码目录下的config.h

　　注释掉：

　　#define malloc rpl_malloc

　　soapcpp和wsdl2h在编译过程中会生成同事这两个工具也在编译时会被用来生成一些特定的文件，所以如果soapcpp和wsdl2h 如果被编译成arm架构则无法在PC上执行，也就意味着接下的编译无法完成，所以这里选择不编译这两个文件，而选择使用上节编译所生产的x86架构的对应 文件。

　　修改gsoap/src/Makefile

　　注释掉

　　soapcpp2$(EXEEXT): $(soapcpp2_OBJECTS) $(soapcpp2_DEPENDENCIES) $(EXTRA_soapcpp2_DEPENDENCIES)

　　@rm -f soapcpp2$(EXEEXT)

　　$(AM_V_CCLD)$(soapcpp2_LINK) $(soapcpp2_OBJECTS) $(soapcpp2_LDADD) $(LIBS)

　　修改gsoap/wsdl/Makefile

　　wsdl2h$(EXEEXT): $(wsdl2h_OBJECTS) $(wsdl2h_DEPENDENCIES) $(EXTRA_wsdl2h_DEPENDENCIES)

　　@rm -f wsdl2h$(EXEEXT)

　　$(AM_V_CXXLD)$(wsdl2h_LINK) $(wsdl2h_OBJECTS) $(wsdl2h_LDADD) $(LIBS)

　　拷贝x86架构下的soapcpp和wsdl2h到工程源码目录下：

　　$ cp /home/linux/gsoap/gsoap-x86/bin/soapcpp2 /home/linux/gsoap/gsoap-2.8/gsoap/src/

　　$ cp /home/linux/gsoap/gsoap-x86/bin/wsdl2h /home/linux/gsoap/gsoap-2.8/gsoap/wsdl/

　　编译

　　$ make

　　安装

　　$ make install

addserver.c

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

int main(int args,char **argv)
{
 int m,s;
 struct soap add_soap;
 soap_init(&add_soap);
 soap_set_namespaces(&add_soap,namespaces);
 if(args<2)
 {
    printf("usage:%s\n",argv[0]);
    exit(1);
 }
 else
 {
     m = soap_bind(&add_soap,NULL,atoi(argv[1]),100);

     exit(-1);
     }

     for(;;)

}

int ns2__add(struct soap *add_soap,int num1,int num2,int *sum)

    if(add_soap.error)
    {

{
    int resutl = -1;
    char server[128]={0};
    int num1;
    int num2;
    int sum;
    if(argc<4)
    {
        printf("usage:%s num1 num2\n",argv[0]);
        exit(1);
    }
    strcpy(server,argv[1]);
    num1 = atoi(argv[2]);
    num2 = atoi(argv[3]);
    resutl = add(server,num1,num2,&sum);
    if(resutl!=0)
    {
        printf("soap error,errorcode=%d\n",resutl);
    }
    else

    }
    return 0;

}

//x86 linux Makefile

GSOAP_ROOT=/usr/local/gSOAP-x86
WSNAME=add
CC= g++ -g -DWITH_NONAMESPACES
INCLUDE=-I $(GSOAP_ROOT)/include
SERVER_OBJS = soapC.o stdsoap2.o soapServer.o addserver.o
CLIENT_OBJS = soapC.o stdsoap2.o soapClient.o addclient.o addtest.o

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

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

//arm-linux Makefile

GSOAP_ROOT=/usr/local/gSOAP-arm
WSNAME=add
CC= arm-linux-g++ -g -DWITH_NONAMESPACES
INCLUDE=-I $(GSOAP_ROOT)/include
SERVER_OBJS = soapC.o stdsoap2.o soapServer.o addserver.o
CLIENT_OBJS = soapC.o stdsoap2.o soapClient.o addclient.o addtest.o

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

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

  2、编译
   先
   $soapcpp2 -c add.h 产生soap文件
   $make client 得到客户端程序
   $make all 得到服务端程序
（可分别编译X86 与 ARM板程序，仅仅是执行位置不一样，编译后程序不依赖任何库，可在任意目录执行）
  3、执行
  服务器端：$./addserver 8000 该服务端口绑定为8000端口
成功：Socket connection successful:master socket=3
客服端连接成功：socket connecntion successful:slave socket = 4

  客服端：$./addclient 192.168.7.7 8000  1 2
               server is 192.168.7.7:8000,num1 is 1,num2 is 2 1+2=3
   这里服务器IP地址，加端口号，加 SOAP参数
三、WSDL天气获取
1、新建目录
$weather
2、从服务器下载头文件
$wsdl2h -c -o  weather.h
//可ping是否通
3、生成客户代码
$soapcpp2 -x -C -c weather.h
-x不生成xml文件
-C 仅仅生存客服端代码
4.拷贝gsoap目录下的stdsoap2.h stdsoap2.c 到weather目录下
5、编写客户端程序
// 数据结构参考了weather.h和

#include <stdio.h>
#include "soapH.h"
#include <string.h>
#include "WeatherWSSoap.nsmap"

//author: jon/2016/08/01

#define CITY_NAME "深圳"

int main(int argc,char *argv[])
{
    struct soap soap;
    int ret = 0;
    int element = 0;
    int i=0;
    struct _ns1__getWeather myCitWeather;
    myCitWeather.theCityCode = CITY_NAME;
    //myCitWeather.theUserID = 0;

    struct _ns1__getWeatherResponse myRetnWeather;

    soap_init(&soap);
    soap_set_mode(&soap,SOAP_C_UTFSTRING);
    soap.mode |=SOAP_C_UTFSTRING;

    if(soap_call___ns1__getWeather(&soap,NULL,NULL,&myCitWeather,&myRetnWeather)==SOAP_OK)
    {
         int Size = myRetnWeather.getWeatherResult->__sizestring;
         for(i=0;i {
            printf("is %d   get %s\n",i,myRetnWeather.getWeatherResult->string[i]);
         }
    }
    soap_destroy(&soap);
    soap_end(&soap);
    soap_done(&soap);
    return 0;
}

6.makefile
#CROSS_COMPILER=

CC:=$(CROSS_COMPILER)gcc
GCC:=$(CROSS_COMPILER)g++

all:
    $(CC) -o weather weather.c soapC.c soapClient.c stdsoap2.c

clean:
    rm -f weather


7.执行
$make

$./weather
