gsoap入门实例

1. 环境
   VS2008，gsoap_2.8，win7
2. 实例场景：在客户端输入一个字符串，然后传递给服务端计算字符串长度并返回给客户端（附加一些加减乘除法的实现）；
3. 将..\gsoap-2.8\gsoap\bin\win32中的两个exe文件所在路径加入环境变量中，后面有用；
4. 新建一个文件夹，设计一个calculator.h文件，如下（前面几行的注释我也不知道有啥用）

    1 //gsoap ns service name: add
    2 //gsoap ns service namespace: http://localhost/add.wsdl
    3 //gsoap ns service location: http://localhost
    4 //gsoap ns service executable: add.cgi
    5 //gsoap ns service encoding: encoded
    6 //gsoap ns schema namespace: urn:add
    7 int ns__add(int num1, int num2, int* result );
    8 int ns__sub(int num1, int num2, int* result );
    9 int ns__mult( int num1, int num2, int *result);
   10 int ns__divid( int num1, int num2, int *result);
   11 int ns__Hello(char* str,int *len);

    

5. 在该文件夹中打开cmd（方法ctrl+右键 --》在此处打开命令窗口），输入命令：soapcpp2.exe calculator.h
   有关gsoap的命令用法自行百度；
6. 你会发现生成很多很多文件
7. 利用VS2008创建一个calServer的工程，将calculator.h  add.nsmap soapC.cpp soapServer.cpp soapStub.h放入该过程，并且将gsoap-2.8\gsoap下的stdsoap2.h stdsoap2.cpp也添加到该过程；添加完后，在项目属性中的链接器--输入--附加依赖项 中输入wsock32.lib；
8. 在calServer中添加一个main.cpp，代码如下:

     1 #include "soapH.h"
     2 #include "add.nsmap"
     3 #include "stdio.h"
     4 #include <iostream>
     5 using namespace std;
     6 
     7 int main( int argc, char *argv[])
     8 {
     9     struct soap *CalculateSoap = soap_new();                                //创建一个soap
    10     int iSocket_master = soap_bind(CalculateSoap, NULL, 10000, 100);         //绑定到相应的IP地址和端口（）NULL指本机，
    11     //10000为端口号，最后一个参数不重要。
    12     if (iSocket_master< 0)                                                  //绑定出错
    13     {
    14         soap_print_fault(CalculateSoap, stderr);
    15         exit(-1);
    16     }
    17     printf("SoapBind success,the master socket number is:%d\n",iSocket_master); //绑定成功返回监听套接字
    18 
    19     while(1)
    20     {
    21         int iSocket_slaver = soap_accept(CalculateSoap);
    22         if (iSocket_slaver < 0)
    23         {
    24             soap_print_fault(CalculateSoap, stderr);
    25             exit(-2);
    26         }
    27         printf("Get a new connection,the slaver socket number is:%d\n",iSocket_slaver); //绑定成功返回监听套接字
    28         soap_serve(CalculateSoap);
    29         soap_end(CalculateSoap);
    30     }
    31     soap_done(CalculateSoap);
    32     free(CalculateSoap);
    33 
    34     return 0;
    35 }
    36 
    37 /*加法的具体实现*/
    38 int ns__add(struct soap *soap, int num1, int num2, int* result )   
    39 {
    40     if (NULL == result)
    41     {
    42         printf("Error:The third argument should not be NULL!\n");
    43         return SOAP_ERR;
    44     }
    45     else
    46     {
    47         (*result) = num1 + num2;
    48         return SOAP_OK;
    49     }
    50     return SOAP_OK;
    51 }
    52 
    53 /*减法的具体实现*/
    54 int ns__sub(struct soap *soap,int num1, int num2, int* result )
    55 {
    56     if (NULL == result)
    57     {
    58         printf("Error:The third argument should not be NULL!\n");
    59         return SOAP_ERR;
    60     }
    61     else
    62     {
    63         (*result) = num1 - num2;
    64         return SOAP_OK;
    65     }
    66     return SOAP_OK;
    67 }
    68 
    69 /*乘法的具体实现*/
    70 int ns__mult(struct soap *soap, int num1, int num2, int *result)
    71 {
    72     if (NULL == result)
    73     {
    74         printf("Error:The third argument should not be NULL!\n");
    75         return SOAP_ERR;
    76     }
    77     else
    78     {
    79         (*result) = num1 * num2;
    80         return SOAP_OK;
    81     }
    82     return SOAP_OK;
    83 }
    84 
    85 /*除法的具体实现*/
    86 int ns__divid(struct soap *soap, int num1, int num2, int *result)
    87 {
    88     if (NULL == result || 0 == num2)
    89     {
    90         printf("Error:The second argument is 0 or The third argument is NULL!\n");
    91         return SOAP_ERR;
    92     }
    93     else

    98     return SOAP_OK;
    99 }
   100 
   101 int ns__Hello(struct soap *soap, char *str, int *len)
   102 {

   107     }
   108     else

   115     (*len) = strlen(str);
   116     return SOAP_OK;
   117

9. Server端完成，可以运行了。
10. 客户端：利用VS2008创建一个calClient的工程，将calculator.h  add.nsmap soapC.cpp soapClient.cpp soapStub.h放入该过程，并且将gsoap-2.8\gsoap下的stdsoap2.h stdsoap2.cpp也添加到该过程；添加完后，在项目属性中的链接器--输入--附加依赖项 中输入wsock32.lib；
11. 在calClient中添加一个main.cpp，代码如下：

     1 #include "soapH.h"
     2 #include "add.nsmap"
     3 #include "stdio.h"
     4 #include <iostream>
     5 using namespace std;
     6 
     7 int main( int argc, char *argv[])
     8 {
     9     printf("The Client is runing...\n");
    10     int num1 = 110;
    11     int num2 = 11;
    12     int result = 0;
    13 
    14     struct soap *CalculateSoap = soap_new();
    15     //soap_init(CalculateSoap);
    16        注意改你的ip,端口10000不改
    17     char * server_addr = "http://xx.x.x.x:10000";
    18 
    19     int iRet = soap_call_ns__add(CalculateSoap,server_addr,"",num1,num2,&result);
    20     if ( iRet == SOAP_ERR)
    21     {
    22         printf("Error while calling the soap_call_ns__add");
    23     }
    24     else
    25     {
    26         printf("Calling the soap_call_ns__add success。\n");
    27         printf("%d + %d = %d\n",num1,num2,result);
    28     }
    29 
    30     iRet = soap_call_ns__sub(CalculateSoap,server_addr,"",num1,num2,&result);
    31     if ( iRet == SOAP_ERR)
    32     {
    33         printf("Error while calling the soap_call_ns__sub");
    34     }
    35     else
    36     {
    37         printf("Calling the soap_call_ns__sub success。\n");
    38         printf("%d - %d = %d\n",num1,num2,result);
    39     }
    40 
    41     iRet = soap_call_ns__mult(CalculateSoap,server_addr,"",num1,num2,&result);
    42     if ( iRet == SOAP_ERR)
    43     {
    44         printf("Error while calling the soap_call_ns__mult");
    45     }
    46     else
    47     {
    48         printf("Calling the soap_call_ns__mult success。\n");
    49         printf("%d * %d = %d\n",num1,num2,result);
    50     }
    51 
    52     iRet = soap_call_ns__divid(CalculateSoap,server_addr,"",num1,num2,&result);
    53     if ( iRet == SOAP_ERR)
    54     {
    55         printf("Error while calling the soap_call_ns__divid");
    56     }
    57     else
    58     {
    59         printf("Calling the soap_call_ns__divid success。\n");
    60         printf("%d / %d = %d\n",num1,num2,result);
    61     }
    62     char *str = new char[1024];
    63     cin.getline(str,1024);
    64     cout << str <<endl;
    65     int len;
    66     iRet = soap_call_ns__Hello(CalculateSoap,server_addr,"",str,&len);
    67     if ( iRet == SOAP_ERR)
    68     {
    69         printf("Error while calling the soap_call_ns__add");
    70     }
    71     else
    72     {
    73         cout << str << " length is " << len <<" success!\n";
    74     }
    75 
    76     soap_end(CalculateSoap);
    77     soap_done(CalculateSoap);
    78     free(CalculateSoap);
    79 
    80     return 0;
    81 }

     

12. Client端完成，可以先运行Server，在运行Client看看效果。
