gsoap开发webservice 服务端.md
作者：互联网
无WSDL文件
1.编写头文件websever2.h：
1 //gsoap ns service name: calc 2 //gsoap ns service style: rpc 3 //gsoap ns service encoding: encoded 4 //gsoap ns service namespace: http://127.0.0.1:8089/calc.wsdl 5 //gsoap ns service location: http://127.0.0.1:8089/cal 6 //gsoap ns schema namespace: urn:calc 7 int ns__add(double a, double b, double *result); 8 int ns__sub(double a, double b, double *result); 9 int ns__mul(double a, double b, double *result); 10 int ns__div(double a, double b, double *result); 11 int ns__pow(double a, double b, double *result);
2.生成文件：
1 C:\Users\admin>e: 2 E:\>cd E:\4.0projet\webserver2\gsoap_2.9.65\gsoap-2.8\gsoap\bin\win32 3 E:\4.0projet\webserver2\gsoap_2.9.65\gsoap-2.8\gsoap\bin\win32>soapcpp2.exe -i -2 webserver2.h
3.将以下文件拷如项目：
前6个路径：
E:\4.0project\webserver2\gsoap_2.8.65\gsoap-2.8\gsoap\bin\win32
cal.nsmap
soapC.cpp
soapcalService.cpp（名称不固定，以service结尾）
soapcalcService.h（名称不固定，以service结尾）
soapH.h
soapStub.h
以下文件在路径：
E:\4.0project\webserver2\gsoap_2.8.65\gsoap-2.8\gsoap
stdsoap2.h
stdsoap2.cpp
分别添加到Header Files、Resource Files、Source Files内4.编写gSOAPService.cpp：
1 #define _CRT_SECURE_NO_WARNINGS **//一定要添加上**
2 #include "calc.nsmap"
3 #include"soapcalcService.h"
4 #include "iostream" //控件问提只能写“”
5
6 using namespace std;
7
8 //很重要
9 int http_get(struct soap *soap)
10 {
11 FILE*fd = NULL;
12 fd = fopen("E:\\4.0project\\webserver2\\gsoap_2.8.65\\gsoap-2.8\\gsoap\\bin\\win32\\calc.wsdl", "rb"); //open WSDL file to copy
13
14 if (!fd)
15 {
16 return 404; //return HTTP not found error
17 }
18 soap->http_content = "text/xml"; //HTTP header with text /xml content
19 soap_response(soap, SOAP_FILE);
20 for (;;)
21 {
22 size_t r = fread(soap->tmpbuf, 1, sizeof(soap->tmpbuf), fd);
23 if (!r)
24 {
25 break;
26 }
27 if (soap_send_raw(soap, soap->tmpbuf, r))
28 {
29 break; //cannot send, but little we can do about that
30 }
31 }
32 fclose(fd);
33 soap_end_send(soap);
34 return SOAP_OK;
35 }
36 int main(int argc, char *argv[])
37 {
38 calcService cal;
39 cal.fget = http_get;
40 while (1)
41 {
42 if (cal.run(8089))
43 {
44 cal.soap_stream_fault(std::cerr);
45 }
46 }
47 return 0;
48 }
49
50 //自动生成了calcService类，自己重写add等函数
51 /*加法的具体实现*/
52 int calcService::add(double num1, double num2, double* result)
53 {
54 if (NULL == result)
55 {
56 printf("Error:The third argument should not be NULL!\n");
57 return SOAP_ERR;
58 }
59 else
60 {
61 (*result) = num1 + num2;
62 return SOAP_OK;
63 }
64 return SOAP_OK;
65 }
66
67 /*减法的具体实现*/
68 int calcService::sub(double num1, double num2, double* result)
69 {
70 if (NULL == result)
71 {
72 printf("Error:The third argument should not be NULL!\n");
73 return SOAP_ERR;
74 }
75 else
76 {
77 (*result) = num1 - num2;
78 return SOAP_OK;
79 }
80 return SOAP_OK;
81 }
82
83 /*乘法的具体实现*/
84 int calcService::mul(double num1, double num2, double* result)
85 {
86 if (NULL == result)
87 {
88 printf("Error:The third argument should not be NULL!\n");
89 return SOAP_ERR;
90 }
91 else
92 {
93 (*result) = num1 * num2;
94 return SOAP_OK;
95 }
96 return SOAP_OK;
97 }
98
99 /*除法的具体实现*/
100 int calcService::div(double num1, double num2, double* result)
101 {
102 if (NULL == result || 0 == num2)
103 {
104 return soap_senderfault("Square root of negative value", "I can only compute the square root of a non-negative value");
105 return SOAP_ERR;
106 }
107 else
108 {
109 (*result) = num1 / num2;
110 return SOAP_OK;
111 }
112 return SOAP_OK;
113 }
114
115 int calcService::pow(double num1, double num2, double* result)
116 {
117 if (NULL == result || 0 == num2)
118 {
119 printf("Error:The second argument is 0 or The third argument is NULL!\n");
120 return SOAP_ERR;
121 }
122 else
123 {
124 (*result) = num1 / num2;
125 return SOAP_OK;
126 }
127 return SOAP_OK;
128 }
测试：浏览器输入： http://127.0.0.1:8089/calc.wsdl
可以查看wsdl文件 soapUI，新建soap工程，选择对应的wsdl，可以测试使用
已有wsdl文件
部分情况下，客户端已开发完成，需要根据已有wsdl生成.h文件，再通过.h文件生成服务端代码。 根据已有wsdl文件，生成.h文件
D:\JHC00144512\gsoap_2.8.65\gsoap-2.8\gsoap\bin\win32>wsdl2h.exe calc.wsdl修改wsdl地址时，主要修改wsdl文件内最后一部分中的：
<soap:address location="http://127.0.0.1:8089/macWS"/> 内location信息。
