gsoap入門實例

本文轉載自查看原文 2014-07-18 19:23 2307 gsoap/ VS2008/ Web Service

環境
VS2008，gsoap_2.8，win7
實例場景：在客戶端輸入一個字符串，然后傳遞給服務端計算字符串長度並返回給客戶端（附加一些加減乘除法的實現）；
將..\gsoap-2.8\gsoap\bin\win32中的兩個exe文件所在路徑加入環境變量中，后面有用；

新建一個文件夾，設計一個calculator.h文件，如下（前面幾行的注釋我也不知道有啥用）

 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);

在該文件夾中打開cmd（方法ctrl+右鍵 --》在此處打開命令窗口），輸入命令：soapcpp2.exe calculator.h
有關gsoap的命令用法自行百度；
你會發現生成很多很多文件
利用VS2008創建一個calServer的工程，將calculator.h add.nsmap soapC.cpp soapServer.cpp soapH.h soapStub.h放入該工程，並且將gsoap-2.8\gsoap下的stdsoap2.h stdsoap2.cpp也添加到該工程；添加完后，在項目屬性中的鏈接器--輸入--附加依賴項中輸入wsock32.lib；

在calServer中添加一個main.cpp，代碼如下:

  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();                                //創建一個soap
 10     int iSocket_master = soap_bind(CalculateSoap, NULL, 10000, 100);         //綁定到相應的IP地址和端口（）NULL指本機，
 11     //10000為端口號，最后一個參數不重要。
 12     if (iSocket_master< 0)                                                  //綁定出錯
 13     {
 14         soap_print_fault(CalculateSoap, stderr);
 15         exit(-1);
 16     }
 17     printf("SoapBind success,the master socket number is:%d\n",iSocket_master); //綁定成功返回監聽套接字
 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); //綁定成功返回監聽套接字
 28         soap_serve(CalculateSoap);
 29         soap_end(CalculateSoap);
 30     }
 31     soap_done(CalculateSoap);
 32     free(CalculateSoap);
 33 
 34     return 0;
 35 }
 36 
 37 /*加法的具體實現*/
 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 /*減法的具體實現*/
 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 /*乘法的具體實現*/
 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 /*除法的具體實現*/
 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
 94     {
 95         (*result) = num1 / num2;
 96         return SOAP_OK;
 97     }
 98     return SOAP_OK;
 99 }
100 
101 int ns__Hello(struct soap *soap, char *str, int *len)
102 {
103     /*if (NULL == result)

106         return SOAP_ERR;
107     }
108     else
109     {
110         cout << result <<endl;
111         return SOAP_OK;
112     }*/
113     //if (NULL == result)
114     cout << str <<endl;
115     (*len) = strlen(str);
116     return SOAP_OK;

118 }

Server端完成，可以運行了。
客戶端：利用VS2008創建一個calClient的工程，將calculator.h add.nsmap soapC.cpp soapClient.cpp soapH.h soapStub.h放入該工程，並且將gsoap-2.8\gsoap下的stdsoap2.h stdsoap2.cpp也添加到該工程；添加完后，在項目屬性中的鏈接器--輸入--附加依賴項中輸入wsock32.lib；

在calClient中添加一個main.cpp，代碼如下：

 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 }

Client端完成，可以先運行Server，在運行Client看看效果。
注意：客戶端和服務端可以再兩台電腦上允許並訪問。
