DoRequest()

PCHAR CWebServiceLibCurl::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.
