1. web service client application
> wsdl2h -s -o MyHead.h http://www.genivia.com/calc.wsdl
-s 不用 STL
> soapcpp2 -i -C MyHead.h
Option -i (and alternatively option -j) indicates that we want C++ proxy and server objects that include the client (and server) code, -C indicates client-side only
soapcpp2 generates both client and server stubs and skeletons by default
这两步过程中可能会出错，要把必要的文件加上: soap12.h stdsoap2.h stdsoap2.cpp
然后，We use the generated soapcalcProxy class and calc.nsmap XML namespace mapping table to access the Web service. The soapcalcProxy class is a proxy to invoke the service:
1 #include "soapWebService1SoapProxy.h" // 自动生成的头文件 注：不用MyHead.h 2 #include "WebService1Soap.nsmap" 3 4 int main() 5 { 6 WebService1SoapProxy service; 7 _tempuri__GetSum a; 8 _tempuri__GetSumResponse result; 9 //a.soap = soap_new();10 a.a = 1;11 a.b = 5;12 //result.soap = soap_new();13 14 if (service.GetSum(&a, &result) == SOAP_OK)15 std::cout << "the num of 1 and 5 is " << result.GetSumResult << std::endl;16 else17 service.soap_stream_fault(std::cerr);18 service.destroy();19 20 getchar();21 return 0;22 } 编译
如果遇到 stdsoap2.obj : error LNK2001: 无法解析的外部符号_namespaces
参考
在 stdsoap2.h，添加
#ifndef WITH_NONAMESPACES
#define WITH_NONAMESPACES #endif
2. Develop a Web Service (Stand-Alone Server)
1 // File: currentTime.h 2 //gsoap ns service name: currentTime 3 //gsoap ns service namespace: urn:currentTime 4 //gsoap ns service location: http://www.yourdomain.com/currentTime.cgi 5 int ns__currentTime(time_t& response);
> soapcpp2 -i -S currentTime.h
// File: currentTime.cpp#include "soapcurrentTimeService.h" // include the proxy declarations#include "currentTime.nsmap" // include the XML namespace mappingsint main(){ // create server and serve on CGI-based request: currentTimeService server; /*server.serve(); server.destroy(); */ while (server.run(65533) != SOAP_TCP_ERROR) { server.soap_stream_fault(std::cerr); } return 0;}int currentTimeService::currentTime(time_t& response){ response = time(0); return SOAP_OK;} Compile with currentTime.cpp soapC.cpp soapcurrentTimeService.cpp stdsoap2.cpp
run
然后可以由 wsdl 文件生成客户端头文件，and ...
3. C# 调用 gsoap 的 service
参考
用 VS 自带的 wsdl.exe (在 C 盘的某个角落)
> wsdl.exe currentTime.wsdl
生成 currentTime.cs
将 currentTime.cs 放到 C# 的工程中，研究下代码结构，找到 currentTime 的初始化函数：
1 public picture() {2 this.Url = "http://localhost:65432/picture.cgi"; // 改成你的地址 3 } OK，可以用了。
4. 如果要发送 二进制数据，可先将其进行编码(暂时采用 base64 编码，实际场景中应采用更合适的编码算法)，以 string 形式发送。接收端再进行相应解码。
C++ gsoap service 端，读取图片：
1 int pictureService::picture(struct picdata &picture) 2 { 3 char *pic = NULL; 4 unsigned int length = 0; 5 6 std::ifstream is("chicken.jpg", std::ios::binary); 7 if (is) 8 { 9 is.seekg(0, is.beg);10 is.seekg(0, is.end); 11 length = is.tellg();12 is.seekg(0, is.beg);13 14 pic = new char[length];15 16 if (pic == NULL)17 return SOAP_ERR;18 19 is.read(pic, length);20 is.close();21 }22 23 picture.data = base64_encode((unsigned char*)pic, length);24 25 if (pic != NULL)26 {27 delete pic;28 pic = NULL;29 }30 31 return SOAP_OK;32 }
C# 端，调用 webservice，获取一张图片，并保存：
1 picture pic = new picture(); 2 picture1 pic1 = new picture1(); 3 pictureResponse res = pic.Callpicture(pic1); 4 5 string strData = res.picture.data; 6 byte[] bytes = Convert.FromBase64String(strData); 7 8 FileStream fs = new FileStream("D:\\picture.jpg", FileMode.OpenOrCreate); 9 fs.Write(bytes, 0, bytes.Length);10 fs.Close();
以上代码，有待优化。
