Linux下C gsoap client访问java webservice server

1 http://gsoap2.sourceforge.net/ 下载gsoap_2.7.15.tar.gz

2 tar -zxvf gsoap_2.7.15.tar.gz

3 ./configure(默认安装在/usr/local/share/gsoap目录下，也可以使用 ./configure –-prefix=/usr/local/gsoap指定安装路径)

4 make

5 su输入密码转到root用户

6 make install

7 创建工程目录，mkdir calculator

8 进入工程目录cd calculator

9 cp /home/jimmy/development/webservice/gsoap-2.7/gsoap/stdsoap2.c .
  cp /home/jimmy/development/webservice/gsoap-2.7/gsoap/stdsoap2.h .

10 mkdir include

14 创建calculator.c，内容如下：

   1 #include <stdio.h>
   2 #include "soapH.h"
   3 #include "CalculatorPortBinding.nsmap"
   4
   5 int main(int argc, char *argv[])
   6 {
   7         struct soap *soap = soap_new();
   8         struct ns1__add add;
   9         struct ns1__substract sub;
  10         struct ns1__multiply mul;
  11         struct ns1__divide div;
  12         struct ns1__addResponse add_ret;
  13         struct ns1__substractResponse sub_ret;
  14         struct ns1__multiplyResponse mul_ret;
  15         struct ns1__divideResponse div_ret;
  16
  17         int result;
  18
  19         add.arg0 = 1;
  20         add.arg1 = 2;
  21
  22         sub.arg0 = 1;
  23         sub.arg1 = 2;
  24
  25         mul.arg0 = 1;
  26         mul.arg1 = 2;
  27
  28         div.arg0 = 8;
  29         div.arg1 = 2;
  30
  31
  32         if(soap_call___ns1__add(soap, NULL, NULL, &add, &add_ret) == SOAP_OK)
  33                 printf("The sum of 1 and 2 is %d\n", add_ret.return_);
  34         else
  35                 soap_print_fault(soap, stderr);
  36
  37         if(soap_call___ns1__substract(soap, NULL, NULL, &sub, &sub_ret) == SOAP_OK)
  38                 printf("The substract of 1 and 2 is %d\n", sub_ret.return_);
  39         else
  40                 soap_print_fault(soap, stderr);
  41
  42         if(soap_call___ns1__multiply(soap, NULL, NULL, &mul, &mul_ret) == SOAP_OK)
  43                 printf("The multiply of 1 and 2 is %d\n", mul_ret.return_);
  44         else
  45                 soap_print_fault(soap, stderr);
  46
  47         if(soap_call___ns1__divide(soap, NULL, NULL, &div, &div_ret) == SOAP_OK)
  48                 printf("The divide of 8 and 2 is %d\n", div_ret.return_);
  49         else
  50                 soap_print_fault(soap, stderr);
  51
  52         soap_end(soap);
  53         soap_free(soap);
  54 }


15 创建Makefile

#INCLUDE=$(GSOAP_ROOT)
INCLUDE=./include
OBJS=soapC.o stdsoap2.o soapClient.o calculator.o
calculator: $(OBJS)
  gcc -I $(INCLUDE) -o calculator $(OBJS)
.PHONY: clean
clean:
  rm *.o calculator


16 make

cc    -c -o soapC.o soapC.c
cc    -c -o stdsoap2.o stdsoap2.c
cc    -c -o soapClient.o soapClient.c
cc    -c -o calculator.o calculator.c
gcc -I ./include -o calculator soapC.o stdsoap2.o soapClient.o calculator.o

17 ./calculator

The sum of 1 and 2 is 3
The substract of 1 and 2 is -1
The multiply of 1 and 2 is 2
The divide of 8 and 2 is 4

19 总结

把所有的xml文件删除依然可以正确编译运行
soapStub.h中包含所有的在calculator.c中使用的结构体和函数声明
soapcpp2常用选项
     * -C 仅生成客户端代码
     * -S 仅生成服务器端代码
     * -L 不要产生soapClientLib.c和soapServerLib.c文件
     * -c 产生纯C代码，否则是C++代码(与头文件有关)
     * -I 指定import路径（见上文）
     * -x 不要产生XML示例文件
     * -i 生成C++包装，客户端为xxxxProxy.h(.cpp)，服务器端为xxxxService.h(.cpp)。
/usr/local/bin/soapcpp2 -c calculator.h则产生服务器端和客户端的代码


20、安装注意：
在README.txt文件中：
To build without OpenSSL support, use:

        $ ./configure --disable-openssl
        $ make
        $ make install

我在ubuntu下安装采用此方法
