Standard C/A + + program calls WebService via gSOAP

I. Environmental preparedness

In this article, all programs are developed under Linux and tested to work properly.

In the development process, we need to use gSOAP, can be downloaded from the following Web site: http://www.cs.fsu.edu/~engelen/soap.html

I downloaded the gsoap_2.7.12.tar.gz.

Download down to decompress, according to the normal installation process to compile, install.

# tar ZXVF gsozp_2.7.12.tar.gz

# CD gsoap_2.7.12

#./CONFIGURE–-PREFIX=/USR/LOCAL/GSOAP (Specify Installation path)

# make

# make Install

Second, the production of related documents

1, through the WSDL document, the production of C + + header files

# /usr/local/gSOAP/bin/wsdl2h –c –o TestHeader.h http://192.168.0.151:8080/services/TestWS?wsdl

2, copy gSOAP source code in the Import folder under the Stlvector.h file to TestHeader.h the same directory, if the WSDL document when parsing the use of the-s parameter, that is, do not use STL, you do not need to copy this file.

3, parse TestHeader.h file, generate stub program

# /usr/local/gSOAP/bin/soapcpp2 –c –C TestHeader.h

The parameter-C in the command generates a standard C program and, without this parameter, generates a C + + program.

The parameter-C in the command generates only the client program, and without this parameter, the client and server-side programs are generated by default.

Third, carry out related development

1. New Project

Create a new C project and copy the file you just generated to the project, set the engineering properties, include the gSOAP source code directory, link properties, need to include the file Libgsoap.a (developed using C) or LIBGSOAP++.A (developed using C + +).

2. Code Development

WebService can refer to the generated soapStub.h file as a specific invocation.

Demo code (call WebService's AddUser):

#include "soapH.h"
#include "TestHeaderHttpBinding.nsmap"
int main()
{
　　　　struct soap clientSOAP;
　　　　struct _ns1__addUser addUserMsg;
　　　　struct _ns1__addUserResponse addUserResponse;
　　　　soap_init(&clientSOAP);
　　　　addUserMsg.in0 = "test";
　　　　addUserMsg.in1 = "test";
　　　　addUserMsg.in2 = "test";
　　　　if(soap_call___ns1__addUser(&clientSOAP, NULL, NULL, &addUserMsg, &addUserResponse) == SOAP_OK)
　　　　{
　　　　　　　　printf("%s\n", *addUserResponse.out);
　　　　}
　　　　else
　　　　{
　　　　　　　　printf("Error\n");
　　　　}
　　　　
　　　　soap_destroy(&clientSOAP);
　　　　soap_end(&clientSOAP);
　　　　soap_done(&clientSOAP);
　　　　return 0;
}

Normally, you can see the processing results returned by the WebService at the console after the build runs.

In this code, _ns1__adduser, _ns1__adduserresponse, Soap_call___ns1__adduser are all available in soapStub.h, and specific applications may generate different code depending on the server.
