gsoap development webservice server .md

No WSDL file

1. Write a header file 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. Generate file:

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. Copy the following files such as project:

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 ** // Be sure to add the ** 
  2 #include " calc.nsmap "  
  3 #include " soapcalcService.h " 
  4 #include " iostream "   // Control asked to mention only write ""

 29             break; //cannot send, but little we can do about that
 30         }
 31     }
 32     fclose(fd);

 34     return SOAP_OK;

Test: browser and enter:  http://127.0.0.1:8089/calc.wsdl
can view the wsdl file soapUI, the new soap project, select the corresponding wsdl, can be tested using

Existing wsdl file

In some cases, the client has been developed, based on existing needs wsdl generated .h file, and then generate the server code via .h file. According to the existing wsdl file to generate .h file

D:\JHC00144512\gsoap_2.8.65\gsoap-2.8\gsoap\bin\win32>wsdl2h.exe calc.wsdl

When modify wsdl address, the last part of the main changes in the wsdl file:

<soap:address location="http://127.0.0.1:8089/macWS"/> In the location information.
