Constructor & Destructor Documentation

CWebServiceWinInet()

CWebServiceWinInet::CWebServiceWinInet

(

)

Constructs a CWebService object and immediately establishes a connection to the "testman" Web Service.

Definition at line 14 of file CWebServiceWinInet.cpp.

{
    /* Zero-initialize variables */
    m_hHTTP = NULL;
    m_hHTTPRequest = NULL;
 
    /* Establish an internet connection to the "testman" server */
    m_hInet = InternetOpenW(L"rosautotest", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
 
    if(!m_hInet)
        FATAL("InternetOpenW failed\n");
}

~CWebServiceWinInet()

CWebServiceWinInet::~CWebServiceWinInet ( )

virtual

Destructs a CWebService object and closes all connections to the Web Service.

Definition at line 30 of file CWebServiceWinInet.cpp.

    if(m_hInet)
        InternetCloseHandle(m_hInet);

Member Function Documentation

DoRequest()

PCHAR CWebServiceWinInet::DoRequest ( const char *  Hostname, INTERNET_PORT  Port, const char *  ServerFile, const string &  InputData  )

overrideprivatevirtual

Sends data to the Web Service.

Parameters

InputData

A std::string containing all the data, which is going to be submitted as HTTP POST data.

Returns

Returns a pointer to a char array containing the data received from the Web Service. The caller needs to free that pointer.

Implements CWebService.
